The approximate height of the projectile after 3 seconds using 6 rectangles is 335.45 feet.

We have,

To approximate the height of the projectile after 3 seconds using 6 rectangles, we can use the Riemann sum with a width of Δt = 0.5 seconds.

First, we need to find the velocity of the projectile at each of the six-time intervals:

v(0.5) = - 15.4(0.5) + 147 = 139.3

v(1.0) = - 15.4(1.0) + 147 = 131.6

v(1.5) = - 15.4(1.5) + 147 = 123.9

v(2.0) = - 15.4(2.0) + 147 = 116.2

v(2.5) = - 15.4(2.5) + 147 = 108.5

v(3.0) = - 15.4(3.0) + 147 = 100.8

Next, we can use the Riemann sum formula to approximate the height of the projectile after 3 seconds:

∫v(t)dt from t=0 to t=3

≈ Δt [v(0)/2 + v(0.5) + v(1.0) + v(1.5) + v(2.0) + v(2.5) + v(3.0)/2]

≈ 0.5 [0 + 139.3 + 131.6 + 123.9 + 116.2 + 108.5 + 100.8/2]

≈ 0.5 [139.3 + 131.6 + 123.9 + 116.2 + 108.5 + 50.4]

≈ 0.5 [670.9]

≈ 335.45

(a) The cumulative distribution function (CDF) of Y is given by:

F_Y(y) = P(Y <= y) = 1 - P(Y > y) = 1 - P(X1 > y, X2 > y, ..., Xn > y)

Since X1, X2, ..., Xn are independent and uniformly distributed on [θ1, θ2], we have:

P(Xi > y) = (θ2 - y) / (θ2 - θ1) for θ1 <= y <= θ2

P(Xi > y) = 0 for y < θ1

P(Xi > y) = 1 for y > θ2

Therefore,

F_Y(y) = 1 - P(X1 > y, X2 > y, ..., Xn > y)

= 1 - P(X1 > y) * P(X2 > y) * ... * P(Xn > y)

= 1 - [(θ2 - y) / (θ2 - θ1)]^n for θ1 <= y <= θ2

The density function of Y is the derivative of the CDF:

f_Y(y) = d/dy [1 - [(θ2 - y) / (θ2 - θ1)]^n]

= n(θ2 - y)^(n-1) / (θ2 - θ1)^n for θ1 <= y <= θ2

(b) The expectation of Y is:

E(Y) = ∫θ1^θ2 y * f_Y(y) dy

= ∫θ1^θ2 y * n(θ2 - y)^(n-1) / (θ2 - θ1)^n dy

= n/(n+1) * (θ2 - θ1) / 2

(c) Since Y is an unbiased estimator of θ2, we have:

E(Y) = θ2

n/(n+1) * (θ2 - θ1) / 2 = θ2

θ2 = 2/n * (n/(n+1) * (θ2 - θ1) + θ1)

Therefore, an unbiased estimator for θ2 is:

θ2_hat = 2/n * (n/(n+1) * (X_bar - θ1) + θ1)

where X_bar is the sample mean of X1, X2, ..., Xn.

The optimal solution to the primal problem is z = 16, with x1 = 0, x2 = 0, x3 = 4, and x4 = 0.

To find an optimal solution to the dual problem of the primal linear programming problems in Exercises 6 and 8, we can use the final tableau determined in solving the primal problem.

Exercise 6: Maximize z = 2x1 + x2 + 3x3 subject to 2x1 - x2 + 3x3 ≤ 5, 6x1 + 3x2 + 5x3 ≤ 10, 2x1 + x2 ≤ 7, x1, x2, x3 ≥ 0.

The primal problem has three constraints, so the dual problem will have three variables. Let y1, y2, and y3 be the dual variables corresponding to the three primal constraints, respectively. The dual problem is:

Minimize w = 5y1 + 10y2 + 7y3 subject to 2y1 + 6y2 + 2y3 ≥ 2, -y1 + 3y2 + y3 ≥ 1, 3y1 + 5y2 ≤ 1, y1, y2, y3 ≥ 0.

To find the optimal solution to the dual problem, we can use the final tableau of the primal problem:

   | x1 | x2 | x3 |  RHS |
----|----|----|----|-----|
x2  |  0 |  1 |  0 | 1/2 |
x4  |  2 | -1 |  3 | 5/2 |
x5  |  6 |  3 |  5 | 10  |

The primal problem is in standard form, so the dual problem is also in standard form. The coefficients of the primal objective function become the constants on the right-hand side of the dual constraints, and vice versa. The final tableau of the primal problem shows that x2 and x4 are the basic variables, so the dual variables corresponding to these constraints are nonzero. The other dual variable, y3, is zero. We can read off the optimal solution to the dual problem:

y1 = 0, y2 = 1/2, y3 = 0, w = 5/2.

Therefore, the optimal solution to the primal problem is z = 5/2, with x1 = 0, x2 = 1/2, and x3 = 0.

Exercise 8: Minimize z = 4x1 + x2 + x3 + 3x4 subject to 2x1 + x2 + 3x3 + x4 ≤ 12, 3x1 + 2x2 + 4x3 = 5, 2x1 - x2 + 2x3 + 3x4 = 8, 3x1 + 4x2 + 3x3 + x4 ≥ 2, x1, x2, x3, x4 ≥ 0.

The primal problem has four constraints, so the dual problem will have four variables. Let y1, y2, y3, and y4 be the dual variables corresponding to the four primal constraints, respectively. The dual problem is:

Maximize w = 12y1 + 5y2 + 8y3 + 2y4 subject to 2y1 + 3y2 + 2y3 + 3y4 ≤ 4, y1 + 2y2 - y3 + 4y4 ≤ 1, 3y1 + 4y2 + 2y3 + 3y4 ≤ 1, y1, y2, y3, y4 ≥ 0.

To find the optimal solution to the dual problem, we can use the final tableau of the primal problem:

   | x1 | x2 | x3 | x4 | RHS |
----|----|----|----|----|-----|
x3  |  2 | -1 |  2 |  3 |  8  |
x4  |  3 |  4 |  3 |  1 |  2  |

Answer:

x + 2x + 3x = 20

6x = 20

x = 3 1/3 cm, so 2x = 6 2/3 cm and

3x = 10 cm

The lengths are 3 1/3 cm, 6 2/3 cm, and 10 cm.

The length of the third side is BC ≈ 1315.5.

Let the two sides of the triangle with given altitudes be AB=1010 and AC=1515. Let h be the length of the altitude from A to BC.

Let D and E be the feet of the perpendiculars from A to BC and from B to AC, respectively. Then we have:

BD = AB - AD = 1010 - h

CE = AC - AE = 1515 - h

Since the length of the altitude from A to BC is the average of the lengths of the altitudes to the two given sides, we have:

h = (BD + CE) / 2

h = [(1010 - h) + (1515 - h)] / 2

2h = 2525 - h

3h = 2525

h = 2525 / 3

Now we use the Pythagorean theorem on the right triangle ABD:

[tex]AD^2 + BD^2 = AB^2[/tex]

[tex]h^2 + (1010 - h)^2 = 1010^2[/tex]

Expanding and simplifying, we get:

[tex]2h^2 - 2020h + 515 = 0[/tex]

Solving for h using the quadratic formula, we get:

h = [tex](2020 ± sqrt(2020^2 - 4(2)(515))) / (2(2))[/tex]

h ≈ 808.6 or h ≈ 1511.4

We take the smaller value of h since the altitude is shorter than the length of the side opposite to it. Therefore, h ≈ 808.6.

Now we can use the Pythagorean theorem on the right triangle ABC:

[tex]BC^2 = AC^2 - h^2[/tex]

[tex]BC^2 = 1515^2 - (808.6)^2[/tex]

BC ≈ 1315.5

The probability that at least 1 patient will arrive during this time is approximately 0.9967 or 99.67%. This information will help you staff the ER with the optimal number of doctors and nurses to handle the patient load.

As the human resource manager for the Cookeville Regional Medical Center's Emergency room, we need to calculate the probability that at least 1 patient will arrive between 11pm and midnight on Friday night.

Since the number of patients follows a Poisson distribution with a mean of 5.7, we can use the Poisson distribution formula:

P(X ≥ 1) = 1 - P(X = 0)

where X represents the number of patients arriving during this time.

To calculate P(X = 0), we can use the Poisson distribution formula:

P(X = 0) = (e^-λ * λ^0) / 0!

where λ is the mean number of patients, which is 5.7 in this case.

Plugging in the values, we get:

P(X = 0) = (e^-5.7 * 5.7^0) / 0! = 0.0030

Therefore,

P(X ≥ 1) = 1 - P(X = 0) = 1 - 0.0030 = 0.9970

So the probability that at least 1 patient will arrive between 11pm and midnight on Friday night is 0.9970 or approximately 99.7%.

This information can be used by the Human Resources Director to staff the ER with the optimal number of doctors and nurses to handle the expected patient volume during this time.

As the human resource manager for the Cookeville Regional Medical Center's Emergency room, you need to calculate the probability that at least 1 patient will arrive between 11pm and midnight on a Friday night. The number of patients follows a Poisson distribution with a mean of 5.7 patients.

To find the probability that at least 1 patient will arrive, we will first calculate the probability that no patients arrive (P(X=0)) and then subtract it from 1. The formula for the Poisson distribution is:

P(X = k) = (e^(-λ) * λ^k) / k!

where λ is the mean (5.7 patients in this case), k is the number of patients, and e is the base of the natural logarithm (approximately 2.71828).

To calculate P(X=0):

P(X = 0) = (e^(-5.7) * 5.7^0) / 0!
         = (e^(-5.7) * 1) / 1
         ≈ 0.0033

Now, to find the probability of at least 1 patient arriving, we will subtract the probability of no patients arriving from 1:

P(X ≥ 1) = 1 - P(X = 0)
        = 1 - 0.0033
        ≈ 0.9967

So, the probability that at least 1 patient will arrive during this time is approximately 0.9967 or 99.67%. This information will help you staff the ER with the optimal number of doctors and nurses to handle the patient load.

If we pick 23 fruits at random, then 7% of the time, their mean weight will be greater than 210.8 grams.

To solve this problem, we need to use the Central Limit Theorem, which states that the sampling distribution of the means of a random sample from any population will be approximately normally distributed if the sample size is large enough.

In this case, since we are picking 23 fruits at random, we can assume that the sampling distribution of the mean weight of the fruits will be approximately normal with a mean of 204 grams and a standard deviation of 16/sqrt(23) grams.

To find the weight of the fruits such that their mean weight will be greater than a certain amount 7% of the time, we need to find the z-score associated with that probability using a standard normal distribution table. The z-score can be calculated as:

z = invNorm(0.93) = 1.475

where invNorm is the inverse normal function. This means that the weight of the fruits such that their mean weight will be greater than this amount 7% of the time is:

Answer:

the first one because Albert sat on apple tree and discovered u don't have a father

Answer: A

Step-by-step explanation:

Reject the null hypothesis at the 0.020 level of significance and conclude that the population mean is less than 7.

To find the critical value for the test statistic, we first need to determine the level of significance or alpha (α). In this case, the significance level is given as 0.020.

Since this is a one-tailed test (alternative hypothesis is less than 7), we will use a z-test and look up the critical value from the z-table.

Using a standard normal distribution table, we can find the z-score that corresponds to a probability of 0.020 in the left-tail. The critical value is the negative z-score that corresponds to the probability of 0.020.

Looking up the z-score in the table or using a calculator, we find that the critical value for a significance level of 0.020 is -2.054.

This means that if our calculated test statistic falls below -2.054, we can reject the null hypothesis at the 0.020 level of significance and conclude that the population mean is less than 7.

n = 18 (number of trials)

p = 0.3 (probability of success, i.e., an order being placed)

q = 1 - p = 0.7 (probability of failure, i.e., no order being placed)

We want to find the probability of more than 3 successes, which can be written as:

P(X > 3) = 1 - P(X ≤ 3)

To calculate this, we need to use the binomial cumulative distribution function or a binomial probability table. Alternatively, we can use the complement rule:

P(X > 3) = 1 - P(X ≤ 3) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)]

P(X = k) = (n choose k) * [tex]p^k * q^{(n-k)[/tex]

where (n choose k) = n! / (k! * (n-k)!) is the binomial coefficient.

P(X = 0) = (18 choose 0) * [tex]0.3^0 * 0.7^1^8[/tex] = 0.000005

P(X = 1) = (18 choose 1) * [tex]0.3^1 * 0.7^1^7[/tex] = 0.00016

P(X = 3) = (18 choose 3) *[tex]0.3^3 * 0.7^1^5[/tex] = 0.0086

Therefore

P(X > 3) = 1 - [0.000005 + 0.00016 + 0.0017 + 0.0086] ≈ 0.9896

f_x = 2x

f_y = 2y

f_z = -8z

Then, we can evaluate these partial derivatives at the given point (-3, -6, 1):

f_x(-3, -6, 1) = -6

f_y(-3, -6, 1) = -12

f_z(-3, -6, 1) = -8

n = <f_x(-3, -6, 1), f_y(-3, -6, 1), f_z(-3, -6, 1)> = <-6, -12, -8>

To find the equation of the tangent plane, we can use the point-normal form of the equation of a plane:

n · (r - P) = 0

where n is the normal vector, P is the given point, and r is a general point on the plane. Substituting in the values we have, we get:

Simplifying and expanding the dot product, we get:

Simplifying further, we get:

-6r + 18 - 12r + 72 - 8r + 8 = 0

Combining like terms, we get:

A 99% confidence interval for the true proportion of teens aged 13-17 who have their own desktop or laptop computer can be calculated using the information provided in the nationwide random survey of 1,500 teens. In the survey, approximately 65% (or 0.65) of the respondents indicated that they have their own computer.

To calculate the confidence interval, we'll use the formula:

CI = p-hat ± Z * √(p-hat * (1 - p-hat) / n)

where:
- CI represents the confidence interval
- p-hat is the sample proportion (0.65)
- Z is the Z-score corresponding to the desired confidence level (2.576 for a 99% confidence interval)
- n is the sample size (1,500)

Now, let's plug in the values:

CI = 0.65 ± 2.576 * √(0.65 * 0.35 / 1,500)

CI = 0.65 ± 2.576 * 0.0128

CI = 0.65 ± 0.0330

So, the 99% confidence interval is (0.617, 0.683).

With 90% confidence, we can say that the population mean falls between 20.96 and 23.04.

To construct the confidence interval for a population mean, we can use the formula:

Confidence interval = sample mean ± (critical value) x (standard error)

where the standard error is the standard deviation of the sample mean, which is calculated as:

standard error = sample standard deviation / √sample size

The critical value depends on the desired level of confidence and the degrees of freedom (df), which is the sample size minus 1. For a 90% confidence interval and 62 degrees of freedom, the critical value from a t-distribution is 1.667 (found using a t-table or calculator).

Plugging in the values, we get:

standard error = 5 / √64 = 5 / 8 = 0.625

Confidence interval = 22 ± 1.667 x 0.625 = (20.96, 23.04)

The  distance between the ships is increasing at a rate of approximately 18.71 km/h.

To solve this problem, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the two sides are the distance traveled by ship A and the distance traveled by ship B.

distance = rate × time = 40 km/h × 4 h = 160 km

Now let's calculate the distance between the two ships at noon:

distance = √(170² + 0²) = √28900 ≈ 170.13 km

At 4:00 p.m., ship A has traveled 160 km east, and ship B has traveled 25 km/h × 4 h = 100 km north. We can use the Pythagorean theorem to calculate the new distance between the two ships:

distance = √(170² + 160² + 100²) ≈ 244.95 km

Therefore, the distance between the ships at 4:00 p.m. is approximately 244.95 km. To find the rate of change of this distance, we can subtract the initial distance from the final distance and divide by the time interval:

rate of change = (244.95 km - 170.13 km) / 4 h ≈ 18.71 km/h

Therefore, the distance between the ships is increasing at a rate of approximately 18.71 km/h.

The probability that the second light is green, given that the first light is green, is 0.695 or approximately 69.5%.

We can use Bayes' Theorem to find the probability that the second light is green, given that the first light is green. Let G1 and G2 denote the events that the first and second lights are green, respectively. Then we have:

P(G2 | G1) = P(G1 and G2) / P(G1)

We are given that P(G1 and G2) = 0.41, and P(G1) = 0.59. Substituting these values, we get:

P(G2 | G1) = 0.41 / 0.59 = 0.695

Therefore, the probability that the second light is green, given that the first light is green, is 0.695 or approximately 69.5%.

To answer your question, we will use the conditional probability formula:

P(A and B) = P(A) * P(B|A)

In this case, A represents the first light being green, B represents the second light being green, and P(A and B) is the probability of both lights being green. We are given the following:

P(A and B) = 0.41
P(A) = 0.59
We need to find P(B|A), which is the probability that the second light is green given that the first light is green.

Using the formula, we have:

0.41 = 0.59 * P(B|A)

To solve for P(B|A), divide both sides by 0.59:

P(B|A) = 0.41 / 0.59 ≈ 0.6949

Therefore, the probability that the second light is green, given that the first light is green, is approximately 0.6949.

There are 51,121,423 different committees that can be formed from 12 teachers and 32 students if the committee consists of both teachers and students.

To find the number of different committees that can be formed from 12 teachers and 32 students if the committee consists of both teachers and students, we need to use the combination formula. We can choose k members from a group of n members by using the formula:

n choose k = n! / (k! * (n-k)!)

In this case, we want to choose a committee that consists of both teachers and students, so we need to choose at least one teacher and at least one student. We can do this by choosing 1, 2, 3, ..., 11, or 12 teachers, and then choosing the remaining members of the committee from the students.

Let's start with choosing 1 teacher. There are 12 choices for the teacher, and we need to choose the remaining members of the committee from the 32 students. We can choose k students from a group of 32 students using the combination formula:

32 choose k = 32! / (k! * (32-k)!)

So the total number of committees that can be formed with 1 teacher and k students is:

12 * 32 choose k

To find the total number of committees that can be formed with at least one teacher and at least one student, we need to sum up the number of committees for each possible number of teachers:

total = 12 * (32 choose 1) + 12 * (32 choose 2) + ... + 12 * (32 choose 31) + 12 * (32 choose 32)

This is a bit cumbersome to calculate, but fortunately there is a shortcut: we can use the complement rule to find the number of committees that do not include any teachers, and then subtract this from the total number of committees. The number of committees that do not include any teachers is simply the number of committees that can be formed from the 32 students:

32 choose k = 32! / (k! * (32-k)!)

So the total number of committees that can be formed with at least one teacher and at least one student is:

total = 12 * (32 choose 1) + 12 * (32 choose 2) + ... + 12 * (32 choose 31) + 12 * (32 choose 32)
     = 12 * (2^32 - 1) - 32 choose 0
     = 12 * (2^32 - 1) - 1
     = 51,121,423

Therefore, there are 51,121,423 different committees that can be formed from 12 teachers and 32 students if the committee consists of both teachers and students.

Answer: $4$

Step-by-step explanation:

The correct option is b) 3. The average processing time is 4 minutes. A denial of service probability of no more than 0.01 is desired. The average interarrival time is 10 minutes. The system need 3 servers.

To determine how many servers are needed in an Erlang loss system with an average processing time of 4 minutes, a denial of service probability of no more than 0.01, and an average interarrival time of 10 minutes, you can follow these steps:

1. Calculate the traffic intensity (A) using the formula: A = processing time / interarrival time. In this case, A = 4 minutes / 10 minutes = 0.4 Erlangs.

2. Use Erlang's B formula to find the number of servers (s) required to achieve a desired probability of denial of service (P): P = ([tex]A^s[/tex] / s!) / Σ([tex]A^k[/tex] / k!) from k = 0 to s.

3. Iterate through the options provided (a: 2 servers, b: 3 servers, c: 4 servers, d: 5 servers) and find the first option that satisfies the desired probability of denial of service (P ≤ 0.01).

After performing the calculations, you'll find that option b) 3 servers satisfies the desired probability of denial of service. Therefore, the system needs 3 servers to achieve a denial of service probability of no more than 0.01.

Once you complete the 50 trials, you can calculate the total number of heads and tails by adding the counts from the corresponding columns.

Since I'm a text-based AI and cannot physically flip pennies, I'll provide you with a general understanding of the possible outcomes.
When you simultaneously flip two pennies 50 times, there are four possible outcomes for each flip:
1. Both pennies show heads (HH)
2. The first penny shows heads, and the second penny shows tails (HT)
3. The first penny shows tails, and the second penny shows heads (TH)
4. Both pennies show tails (TT)
Each outcome has a probability of 1/4. After flipping the two pennies 50 times, you'll have a total of 100 coin flips. To record the number of heads and tails you get, create a table with four columns: 'HH', 'HT', 'TH', and 'TT'. Then, mark each outcome as you perform the 50 trials.

After 52 hours, approximately 70.7 milligrams of the radioactive substance will remain.

To solve this problem, we can use the exponential decay formula:
N(t) = N0 * e^(-λt)
where N(t) is the amount of substance remaining at time t, N0 is the initial amount of substance, λ is the decay constant, and e is the base of the natural logarithm.
We can find λ by using the fact that half of the substance decays in 36 hours:
N(36) = N0/2
100 mg = 200 mg * e^(-λ * 36)
e^(-λ * 36) = 0.5
-λ * 36 = ln(0.5)
λ = ln(2)/36
Now we can use this value of λ to find N(52):
N(52) = 200 mg * e^(-λ * 52)
N(52) = 200 mg * e^(-ln(2)/36 * 52)
N(52) ≈ 78.1 mg
Therefore, approximately 78.1 milligrams of the radioactive substance will remain after 52 hours.
A scientist is observing a radioactive substance that decays exponentially. Initially, there are 200 milligrams of the substance. After 36 hours, 100 milligrams remain. To determine how many milligrams will remain after 52 hours, we can use the formula:
Final amount = Initial amount * (1/2)^(time elapsed/half-life)
First, we need to find the half-life of the substance. Since it decays to half its initial amount in 36 hours:
Half-life = 36 hours
Now we can plug in the values to find the amount remaining after 52 hours:
Final amount = 200 mg * (1/2)^(52/36) = 200 mg * (1/2)^1.44 ≈ 70.7 mg
After 52 hours, approximately 70.7 milligrams of the radioactive substance will remain.

For multivariate statistical techniques where there is more than one dependent variable, multivariate analysis of variance and covariance and canonical correlation and multiple discriminant analysis can be used.

In data analysis, we look at different variables (or factors) and how they can affect certain situations or outcomes. For example, in marketing, you can look at how the "money spent on advertising" variable affects the "number of sales" variable. A multivariate statistical technique known as factor analysis or multivariate analysis is used to look for patterns among related variables. Multivariate analysis is based on the observation and analysis of more than one statistical outcome variable simultaneously. Many different multivariate statistical techniques such as discriminant analysis, cluster analysis, principal component analysis (PCA) and factor analysis (FA). Therefore, multivariate analysis of variance (MANOVA) is used to measure the effect of multiple independent variables on two or more dependent variables.

Thus, the radius of the right circular cylinder as 2 inches for the given values of lateral surface area (LSA) and volume.

To find the radius of the right circular cylinder, we will use the given lateral surface area (LSA) and volume. The formulas for these are:

LSA = 2 * pi * r * h

Volume = pi * r^2 * h

Where r is the radius, and h is the height of the cylinder.

We are given LSA = 3.5 square inches and Volume = 3.5 cubic inches. Let's plug these values into the formulas:

3.5 = 2 * pi * r * h (1)

3.5 = pi * r^2 * h (2)

Now, we want to isolate the radius. To do this, we can solve equation (1) for h:

h = 3.5 / (2 * pi * r)

Now, substitute this expression for h into equation (2):

3.5 = pi * r^2 * (3.5 / (2 * pi * r))

Simplify the equation by cancelling out pi and 3.5:

1 = r * (1 / (2 * r))

Multiply both sides by 2 * r:

2 * r = r^2

Now, solve for r:

r^2 - 2 * r = 0

r(r - 2) = 0

This gives us two possible values for r: r = 0 and r = 2. Since the radius cannot be 0, we have the radius of the right circular cylinder as 2 inches.

Answer:

According to the Triangle Inequality Theorem, the range of possible lengths for the third side of the triangle, x, is 1 < x < 11.

Step-by-step explanation:

To determine the range of possible lengths for the third side of the triangle, we need to use the Triangle Inequality Theorem.

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

If a, b, and c are the lengths of the sides of a triangle, then:

We have been told that two sides of the triangle are 5 cm and 6 cm.

Let "x" be the length of the third of the triangle.

Using the Triangle Inequality Theorem, we can write the following inequalities:

Simplify the inequalities:

The first inequality tells us that x should be less than 11 cm.

The second inequality tells us that x should be greater than zero (since length cannot be negative).

The third inequality tells us that the x should be greater than 1 cm.

Therefore, the range of possible lengths for the third side is 1 < x < 11.
