Part a.) If you apply the distributive property first to solve the equation, what operation will you need to do last? Part b.) If instead you divide first to solve the equation, what operation would you need to use last?

Answers

Answer 1

The equation is solved and the distributive property is used

Given data ,

a)

If you use the distributive property to solve the equation first, either addition or subtraction will need to be done last, depending on the equation. This is so that you may isolate the variable on one side of the equation or combine like terms after applying the distributive principle, which usually requires addition or subtraction as the last step.

b)

Instead, if you divide first to answer the problem, you would need to apply multiplication as the last operation. This is because, in order to "undo" the division operation and find the variable, you would need to multiply by the reciprocal of the value by which you had divided to isolate the variable. As the inverse operation of division, multiplication would be utilized as the last step in the equation's solution.

Hence , the equations are solved

When a plane flies into the wind, it can travel 3000 mi in 6 h. When it flies with the wind, it can travel the same distance in 5h. Find the rate of the plane in still air and the rate of the wind.

Answers

The rate of the plane in still air is 550 mph, and the rate of the wind is 50 mph.

Let's denote the rate of the plane in still air as "p" and the rate of the wind as "w".

When the plane flies into the wind, its effective speed is reduced by the speed of the wind.

So, the speed of the plane relative to the ground is:

p - w

Similarly, when the plane flies with the wind, its effective speed is increased by the speed of the wind, so its speed relative to the ground is:

p + w

We know that the distance traveled by the plane is 3000 miles in both cases, so we can set up two equations based on the formula:

distance = rate x time

When the plane flies into the wind:

3000 = (p - w) x 6

And when the plane flies with the wind:

3000 = (p + w) x 5

Now we have two equations with two unknowns, which we can solve for "p" and "w".

Let's start by simplifying both equations:

Equation 1: 3000 = 6p - 6w

Equation 2: 3000 = 5p + 5w

We can then solve for one of the variables in terms of the other. For example, we can solve for "p" in terms of "w" by rearranging Equation 2:

5p = 3000 - 5w

p = (3000 - 5w) / 5

We can then substitute this expression for "p" into Equation 1 and solve for "w":

3000 = 6[(3000 - 5w) / 5] - 6w

Multiplying both sides by 5:

15000 = 6(3000 - 5w) - 30w

Distributing the 6:

15000 = 18000 - 30w - 30w

Combining like terms:

15000 = 18000 - 60w

Subtracting 18000 from both sides:

-3000 = -60w

Dividing both sides by -60:

w = 50

Now that we know the rate of the wind is 50 mph, we can substitute this value into either Equation 1 or Equation 2 to solve for "p".

Let's use Equation 2:

3000 = 5p + 5(50)

3000 = 5p + 250

2750 = 5p

p = 550.

A random sample of 10 observations is selected from a normal population. The sample mean was 11 and the sample standard deviation 3.2. Using the 0.1 significance level:

Answers

The sample mean is significantly different from 10 at a 0.1 significance level.

The null hypothesis is a statement about the population parameter that we are testing, and the alternative hypothesis is the complement of the null hypothesis. The significance level is the probability of rejecting the null hypothesis when it is true.

In this case, we can use the following null and alternative hypotheses:

Null hypothesis: The population mean is equal to 10.

Alternative hypothesis: The population mean is not equal to 10.

We will use a two-tailed test because the alternative hypothesis is not directional.

We can use the t-test to test the null hypothesis. The t-test statistic is calculated as follows:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

In this case:

[tex]t = (11 - 10) / (3.2 / \sqrt{10} ) = 1.58[/tex]

We need to find the critical value of t at the 0.1 significance level with 9 degrees of freedom (10 - 1 = 9). We can use a t-table or a statistical software to find this value. The critical value is ±1.833.

Since the calculated t-value of 1.58 is not greater than the critical value of ±1.833, we cannot reject the null hypothesis. We do not have sufficient evidence to conclude that the population mean is different from 10 at the 0.1 significance level.

suppose a data set has a mean of 110 with a standard deviation of 10. What is the minimum relative frequency of data greater than 80 but also less than 140

Answers

The minimum relative frequency of data greater than 80 but less than 140 is 0.9973 or approximately 99.73%.

To find the minimum relative frequency of data greater than 80 but less than 140, we need to use the z-score formula, which measures the number of standard deviations a data point is from the mean.

z = (x - μ) / σ

where x is the data point, μ is the mean, and σ is the standard deviation.

For x = 80:

z = (80 - 110) / 10 = -3

For x = 140;

z = (140 - 110) / 10 = 3

Using a standard normal distribution table or calculator, we can find that the area under the curve between z = -3 and z = 3 is approximately 0.9973.

Therefore, the minimum relative frequency of data greater than 80 but less than 140 is 0.9973 or approximately 99.73%.

g A vat with 500 gallons of beer contains 4% alcohol (by volume). Beer with 6% alcohol is pumped into the vat at a rate of 5 gal/min and the mixture is pumped out at the same rate. What is the percentage of alcohol after an hour

Answers

After an hour, the percentage of alcohol in the vat is approximately 4.92%.

After an hour of pumping beer with 6% alcohol into the vat at a rate of 5 gallons per minute and simultaneously pumping the mixture out at the same rate, the percentage of alcohol in the vat can be calculated as follows:

Initially, the vat has 500 gallons of beer with 4% alcohol content. This means there are 20 gallons of alcohol in the vat (500 * 0.04).

Now, let's consider the beer being pumped in at a rate of 5 gallons per minute with a 6% alcohol content. Over the course of an hour (60 minutes), this amounts to 300 gallons of beer, containing 18 gallons of alcohol (300 * 0.06).

As the mixture is being pumped out at the same rate, only 500 gallons of beer remain in the vat after an hour. The total alcohol in the vat is the sum of the alcohol from the initial beer and the pumped-in beer, minus the amount of alcohol pumped out. The mixture pumped out contains the same proportion of alcohol as the mixture in the vat, so it amounts to (5 gallons/minute * 60 minutes) * X%, where X% is the percentage of alcohol in the mixture at the end of an hour.

To find X%, we can set up the following equation:

20 (initial alcohol) + 18 (alcohol pumped in) - 5 * 60 * X% = 500 * X%

Solving for X, we get:

38 - 300 * X% = 500 * X%

Rearranging and solving for X, we find that:

X% ≈ 4.92%

Two bottling plants package a certain type of sports drink. Suppose the mean volume of all of this type of sports drinks is 20 fluid ounces. Bottling plant A bottles approximately 44688 sports drinks per day. Bottling plant B bottles approximately 177430 sports drinks per day. On a particular day, which bottling plant is less likely to record a mean volume of 21 fluid ounces for the day?

Answers

Based on sample size, bottling plant B is less likely to record a mean volume of 21 fluid ounces for the day compared to bottling plant A.

To determine which bottling plant is less likely to record a mean volume of 21 fluid ounces for the day, we can use the concept of sample size and standard deviation. As the sample size increases, the standard deviation decreases, which means that the mean is more likely to be close to the population mean of 20 fluid ounces.

In this case, bottling plant B has a larger sample size (177430 sports drinks) than bottling plant A (44688 sports drinks), which means that it is less likely to record a mean volume of 21 fluid ounces for the day.

This is because the larger sample size of bottling plant B will lead to a smaller standard deviation and a more accurate estimation of the population mean.

Thus, there are 20 ways for the gambler to choose exactly 3 lucky numbers out of the 6 randomly chosen numbers in a keno game.

To find the number of ways the gambler can choose exactly 3 lucky numbers out of the 6 randomly chosen numbers in a keno game, we need to use combinations. A combination represents the number of ways to choose a certain number of items from a larger set without considering the order.

In this case, we will use the combination formula, which is C(n, k) = n! / (k! * (n-k)!), where n is the total number of items and k is the number of items to be chosen.

Here, n = 6 (the total numbers chosen by the gambler) and k = 3 (the number of lucky numbers to be chosen).

Applying the formula: C(6, 3) = 6! / (3! * (6-3)!)

C(6, 3) = 6! / (3! * 3!)

C(6, 3) = 720 / (6 * 6)

C(6, 3) = 720 / 36

C(6, 3) = 20

Describe how you constructed the curve and discuss its features. The normal distribution curve is centered at square and has 2 points of inflection square representing mu - alpha, and square representing mu + alpha.

Answers

To draw a normal curve with a mean (µ) of 61 and a standard deviation (σ) of 14, you can follow these steps:

1. Begin by plotting the mean (µ = 61) on the horizontal axis.
2. Mark one standard deviation above and below the mean (µ + σ = 61 + 14 = 75 and µ - σ = 61 - 14 = 47).
3. Draw a symmetric bell-shaped curve around the mean, with the curve extending toward the points marked in step 2.

The normal distribution curve is centered at the mean (µ = 61) and has two points of inflection representing µ - σ (47) and µ + σ (75). The curve is symmetric, with its highest point at the mean. As we move further away from the mean in either direction, the curve tapers off and approaches the horizontal axis without actually touching it. Approximately 68% of the data will fall within one standard deviation (between 47 and 75), 95% within two standard deviations, and 99.7% within three standard deviations of the mean.

To choose the correct graph of the normal curve, look for a bell-shaped curve that is symmetric around the mean (61), with points of inflection at 47 and 75. The graph should also reflect the decreasing probability density as you move further from the mean.

The force exerted by an electric charge at the origin on a charged particle at a point (x,y,z) with position vector r = (x,y,z) is F(r) =Kr/||r||^3. Where k is a constant. Find the work done as the particle moves along a straight line from (2, 0, 0) to (2,3,5)

Answers

To find the work done, we need to integrate the force F(r) along the path that the particle moves. Since the path is a straight line, we can parametrize it as r(t) = (2, 0, 0) + t((2,3,5)-(2,0,0)) = (2+2t, 3t, 5t),

where 0 <= t <= 1.

Then, the force F(r(t)) is given by F(t) = K(2+2t, 3t, 5t)/[(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2).

The work done by the force as the particle moves from (2,0,0) to (2,3,5) is given by the line integral:

W = ∫ F(r(t)) · dr(t) from t=0 to t=1

where dr(t) is the differential of r(t) with respect to t.

Now, we need to evaluate the dot product F(r(t)) · dr(t).

Note that dr(t) = (2,3,5) dt, since the path is a straight line.

Therefore: F(r(t)) · dr(t) = K(2+2t, 3t, 5t)/[(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2) · (2,3,5) dt

= K(2+2t)(2) + 3t(3) + 5t(5) / [(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2) dt

= K(4+4t + 9t + 25t) / [(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2) dt

= 38Kt / [(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2) dt

Thus, the work done is:

W = ∫ F(r(t)) · dr(t) from t=0 to t=1

= ∫0^1 38Kt / [(2+2t)^2 + (3t)^2 + (5t)^2]^(3/2) dt

Which method of sampling is based on dividing a population into subgroups, sampling a set of subgroups, and conducting a complete census within the subgroups sampled? a) Judgment sampling b) Systematic sampling c) Continuous process sampling d) Cluster sampling

Answers

The method of sampling that is based on dividing a population into subgroups, sampling a set of subgroups, and conducting a complete census within the subgroups sampled is known as cluster sampling.

This method of sampling is often used when the population is too large to be sampled as a whole or when it is difficult to obtain a comprehensive list of the population.

In cluster sampling, the population is divided into smaller subgroups, or clusters, that are more manageable in size. These clusters are then randomly selected, and a complete census is conducted within each of the selected clusters. This means that every individual within the selected clusters is included in the sample.

Cluster sampling can be more efficient and cost-effective than other sampling methods because it reduces the amount of resources required to sample large populations. It is important to note, however, that cluster sampling can lead to increased sampling error if the selected clusters are not representative of the population as a whole.

In summary, cluster sampling is a method of sampling that involves dividing a population into subgroups, sampling a set of subgroups, and conducting a complete census within the selected subgroups. This method can be an effective way to sample large populations, but it is important to ensure that the selected clusters are representative of the population to minimize sampling error.

Find the area of the region included between the parabolas y² = 4(7+ 1)(x +7+ 1), and y² = 4(7 + 1)(7+1 - x)

Answers

The  area enclosed by the parabolas y² = 32(x + 8) and y² = -32(x - 6) is (64√3)/9.

We can start by simplifying the equations of the parabolas:

y² = 4(7 + 1)(x + 7 + 1)
y² = 4(7 + 1)(7 + 1 - x)

y² = 32(x + 8)
y² = -32(x - 6)

We can see that the parabolas are symmetrical with respect to the y-axis, so we only need to consider the region to the right of the y-axis. To find the points of intersection between the parabolas, we can set the right-hand sides of the equations equal to each other:

32(x + 8) = -32(x - 6)

Expanding and simplifying, we get:

64x + 256 = 192 - 32x
96x = -64
x = -2/3

So the parabolas intersect at x = -2/3. We can find the corresponding y-values by plugging this value of x into either equation:

y² = 32(x + 8)
y² = 32(-2/3 + 8)
y² = 256/3
y = ±(16√3)/3

So the points of intersection are (-2/3, (16√3)/3) and (-2/3, -(16√3)/3).

To find the area between the parabolas, we can integrate the difference between their y-values with respect to x:

A = ∫[0, -2/3] (16√3)/3 - (-16√3)/3 dx + ∫[-2/3, 0] (-16√3)/3 - (16√3)/3 dx
A = ∫[-2/3, 0] 32√3/3 dx
A = (32√3)/3 ∫[-2/3, 0] dx
A = (32√3)/3 [(0) - (-2/3)]
A = (64√3)/9

Therefore, the area enclosed by the parabolas y² = 32(x + 8) and y² = -32(x - 6) is (64√3)/9.

the given functions represent transfer functions of two systems in a control system, and they can be analyzed using various tools in the Laplace domain to determine their behavior and characteristics.

The given functions represent the transfer functions of two systems in a control system. The first transfer function, g(s), has two poles at s=1 and one pole at s=10. The poles at s=1 are repeated twice, indicating that this is a second-order system. The second transfer function, h(s), is a constant function with a value of 1.

To analyze the behavior of these systems, we can use tools such as the Laplace transform, which allows us to convert differential equations into algebraic equations that are easier to solve. The Laplace transform of g(s) can be written as G(s) = 1/(s+1)^2(s+10), and the Laplace transform of h(s) is H(s) = 1.

Once we have the transfer functions in the Laplace domain, we can use them to compute various system parameters such as the frequency response, step response, and stability. For example, the frequency response of a system is given by the magnitude and phase of the transfer function evaluated at different frequencies. The step response of a system is the output of the system when a unit step input is applied, and it can be computed using the inverse Laplace transform.

Muriel is putting crown molding in her bedroom. The room has a length of 15 feet and a width of 12 feet. The molding comes in 10-foot. boards that cost $45 per board. How much will she pay for the molding before tax

Answers

To calculate the total cost of crown molding for Muriel's bedroom before tax, we'll follow these steps:

1. Find the perimeter of the room.
2. Determine the number of boards needed.
3. Calculate the total cost.

Step 1: Find the perimeter of the room.
The formula for the perimeter of a rectangle is P = 2(L + W), where L is the length and W is the width.
P = 2(15 + 12) = 2(27) = 54 feet

Step 2: Determine the number of boards needed.
Each board is 10 feet long, so we need to divide the perimeter by the length of each board.
54 feet / 10 feet = 5.4 boards
Since we can't purchase a fraction of a board, Muriel will need to buy 6 boards.

Step 3: Calculate the total cost.
Each board costs $45, so multiply the number of boards by the cost per board.
6 boards * $45 = $270

Muriel will pay $270 for the crown molding before tax.

The probability of selecting three cans of apple juice is 286/10000.

What is the probability?

The probability of selecting three cans of apple juice is calculated as follows:

Data given:

an ice chest contains 8 cans of apple juice, 6 cans of grape juice, 4 cans of orange juice, and 5 cans of mango juice.

The probability of selecting an apple juice can on the first draw = 8/23

Without replacement, the probability of selecting another apple juice can on the second draw = 7/22

Without replacement, the probability of selecting a third apple juice can on the third draw = 6/21

The probability of selecting three cans of apple juice will be:

(8/23) * (7/22) * (6/21) = 0.0286 or 286/10000

The sides of a rectangle are (x+5) and (x+7). If the area of the rectangle is 120, what is the value of x?

Answers

Thus, the sides of the rectangle are 10 and 12, and the area is indeed 120.

To solve this problem, we can use the formula for the area of a rectangle, which is A = L x W, where A is the area, L is the length, and W is the width.

In this case, we know that the length is x+7 and the width is x+5, and the area is 120. So we can write:

120 = (x+7)(x+5)

Expanding the brackets, we get:

120 = x^2 + 12x + 35

Rearranging, we get:

x^2 + 12x - 85 = 0

Now we can solve for x using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = 12, and c = -85, so we get:

x = (-12 ± √(12^2 - 4(1)(-85))) / 2(1)
x = (-12 ± √(144 + 340)) / 2
x = (-12 ± √484) / 2
x = (-12 ± 22) / 2

So the two possible values of x are -17 and 5. However, we can see that the length and width of the rectangle must be positive, so we can reject the negative value and conclude that:

x = 5
Therefore, the sides of the rectangle are 10 and 12, and the area is indeed 120.

Suppose that n balls are tossed into n bins, where each toss is independent and the ball is equally likely to end up in any bin. What is the expected number of empty bins

Answers

The expected number of empty bins when tossing n balls into n bins, with each toss being independent and equally likely, can be determined using the concept of probability.

Let's define the probability that a specific bin remains empty after n tosses as P(empty). Since each ball has n choices, there are n^n possible ways to distribute the balls. To find the probability that a specific bin is empty, we can consider the situation where balls can be tossed into the remaining n-1 bins, resulting in (n-1)^n possible distributions. Therefore, P(empty) = ((n-1)^n) / (n^n).

Now, to calculate the expected number of empty bins, we can use the concept of linearity of expectation. The expected value of the sum of random variables is equal to the sum of the expected values of the individual random variables. In this case, the random variables represent the empty status of each bin (1 if empty, 0 if not).

The expected number of empty bins is the sum of the probabilities of each bin being empty, which is n * P(empty). So, the expected number of empty bins = n * (((n-1)^n) / (n^n)).

Using this formula, you can determine the expected number of empty bins when n balls are tossed into n bins independently and with equal likelihood.

b. To define the event of selling more than three computers using set notation, we look for outcomes in the sample space where the number of computers sold is greater than 3. This would be the set: {4, 5}.
c. The probability of selling five computers is given in the question as 0.10 (or 10%).

a. The sample space would be {0, 1, 2, 3, 4, 5}, as these are the possible numbers of computers that could be sold tomorrow.

b. The event of selling more than three computers can be defined using set notation as {x | x > 3}, which means the set of all numbers (x) that are greater than 3.

c. The probability of selling five computers would be the probability of the event {5}, which is a singleton set (a set with only one element). Since each number in the sample space has an equal chance of occurring, and there are six possible outcomes in the sample space, the probability of selling five computers would be 1/6.
