I NEED HELP ASAP!! Determine which integer will make the inequality 12 > 2x + 4 true.

S:{8}
S:{4}
S:{12}
S:{−2}

Answers

The value x= -2 makes the inequality  true.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

12 > 2x + 4

Now, if we put x= 8 then

= 2x+ 8

= 2(8)+8

= 16+ 8

= 24 > 12

So, x=8 is not true

Now,  if we put x= 4 then

= 2x+ 8

= 2(4)+8

= 8+ 8

= 16 > 12

So, x=4 is not true

Now,  if we put x= 12 then

= 2x+ 8

= 2(12 )+8

= 24 + 8

= 32 > 12

So, x=12 is not true

and,  if we put x= -2 then

= 2x+ 8

= 2(-2)+8

= -4+ 8

= 4 < 12

So, x=-2 is true.

Step-by-step explanation:

To simplify this expression, we first factor the numerator and denominator, and then cancel any common factors:


x² + 3x - 28 = (x + 7)(x - 4)

x² - 7x + 12 = (x - 3)(x - 4)


So the expression simplifies to:


(x + 7)(x - 4) / (x - 3)(x - 4)The (x - 4)

A square placemat has an area of 169 in.² Sally decides to decorate the placemat by putting fringe around the edges how many inches of fringe will Sally need to buy how many feet is this

Answers

Answer:

4 feet and 4 inches of fringe

Step-by-step explanation:

The length and width of a square are equal to each other

Let x = length of a side of a square

Area of a square = Length × Width

                            = (x inches) × (x inches)

                            = [tex]x^{2}[/tex] [tex]in^{2}[/tex]

The area of the square placemat = 169 [tex]in^{2}[/tex]

∴                                            [tex]x^{2} in^{2}[/tex]  = 169 [tex]in^{2}[/tex]

Taking the square root on both sides of the equation to get rid of the square:

                                             x inches = [tex]\sqrt{169}[/tex] inches

                                            x inches = [tex]\sqrt{169}[/tex] inches

   ([tex]\sqrt{169} =[/tex] ± 13. However, the negative value will be rejected since the length of a side CANNOT be negative)    

        So, x = 13 inches

This means the perimeter of the square = (13 + 13 + 13 + 13) inches

                                                                   = 52 inches

52 inches of fringe will be needed by Sally

Unit conversion:

                                                   I foot = 12 inches

                                      ∴          y feet = 52 inches

     Cross-multiplication is applied:

                       (y feet)(12 inches) = (52 inches)(1 foot)

Isolating y and making it the subject of the formula:

                                   y feet = [tex]\frac{(52 inches)(1 foot)}{12 inches}[/tex]

               

Inches in the numerator and denominator will cancel each other out completely:

                                  y feet = [tex]\frac{52}{12}[/tex] feet

                             

Applying long division:

The highest quotient to be multiplied by 12 to give a number, which is closest to 52 but still less than 52. 12×4 = 48. Therefore, the quotient is 4 and the remainder is 4.

∴ 52 inches = 4 feet and 4 inches

Answers

The best estimate for the African lion population is 14 individuals.

Using the Lincoln-Petersen index to estimate  population

The best estimate for the African lion population can be found using the Lincoln-Petersen index, which is a commonly used method for estimating fish or wildlife populations.

The formula for the Lincoln-Petersen index is:

N = (2 x tagged individuals caught) / (total tagged individuals + total untagged individuals caught)

Plugging in the given values:

N = (2 x 8) / (20 + 160) = 16 / 180 = 0.089

Multiplying N by the number of lions caught (160) will give us the best estimate for the African lion population:

African lion population = N x 160 = 0.089 x 160 = 14.24 (rounded to the nearest whole number, 14)

evaluate the numerical value of the final momentum of the t-shirt using the results from parts a and b.

Answers

The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is the sum of the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied.

The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is calculated by summing the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied. Momentum is a vector quantity which is equal to the product of the mass and velocity of an object. In this case, the t-shirt has a mass of 4 kg and a velocity of 4 m/s. The force of 15 N applied to the t-shirt for 3 seconds causes the t-shirt to accelerate, increasing its velocity from 4 m/s to 8 m/s. This increase in velocity results in an increase in the momentum of the t-shirt from 2 kg⋅m/s to 17.5 kg⋅m/s. Thus, by calculating the change in momentum due to the applied force, we can determine the final momentum of the t-shirt.

Answers

The company produce each month to maximize their profit be (50, 100000).

What is meant by maximize their profit?

To ensure the best output and price levels are realized in order to maximize returns, business firms engage in the process of profit maximization. In order to achieve its profit objectives, the company modifies important variables including sale price, production costs, and output levels.

"Profit maximization" emphasizes the location of this critical point, or the optimal output at which your company is most profitable. An educational non-profit organization called Khan Academy states that "a corporation striving to maximize profit will produce the quantity where 'marginal cost' and 'marginal income' are equal to each other."

Let x be the number of ceiling fans

If the price per fan when you sell x fans exists (300 - 2x), then the amount received for selling x fans exists x(300 - 2x)

The cost for producing x fans is (20x + 100).

Profit = x(300 - 2x) - (20x + 100)

y = (1000 + 20x)(300 - 2x)

simplifying the equation, we get

y = 300000 - 2000x + 6000x - 40x²

y = -40x² + 4000x + 300000

simplifying the above equation, we get

y = -40(x² - 100x + 2500) + 100000

find a nonzero polynomial $p(x)$ passing through the point $(2,0)$ and satisfying the equation $p(x)

Answers

A polynomial of degree n can pass through n + 1 points. So, if we have n + 1 points, we can construct a unique polynomial that passes through all those points.

A nonzero polynomial passing through a specific point (x, y) means that the value of the polynomial at that x-coordinate must be equal to the y-coordinate of the point. So, if the point (2, 0) is one of the points that the polynomial passes through, then we have:

[tex]p(2) = 0[/tex]

We can construct a polynomial with this information. For example, one possible polynomial is:

[tex]p(x) = (x - 2)^2[/tex]

This polynomial satisfies the equation p(2) = 0 since:

[tex]p(2) = (2 - 2)^2 = 0^2 = 0[/tex]

Therefore, the polynomial [tex]p(x) = (x - 2)^2[/tex] is a nonzero polynomial that passes through the point (2, 0) and satisfies the equation p(x). Note that there could be other polynomials that also satisfy the given conditions.

In general, a polynomial of degree n can pass through n + 1 points. So, if we have n + 1 points, we can construct a unique polynomial that passes through all those points.

Answer: We can use the Pythagorean theorem to find the length of the hypotenuse (c) of the triangle:

c = √(a^2 + b^2) = √(75.4^2 + 41.7^2) = √(5702.76 + 1738.69) = √(7441.45)

c ≈ 86.38 yd

Next, we can use the inverse cosine function (arccos) to find angle A:

A = arccos(a/c) = arccos(75.4/86.38)

A ≈ 30.49°

Finally, we can use the complementary angle formula to find angle B:

B = 90° - A

b) n = 25 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 4

c) n = 36 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 3.33

d) n = 100 ⇒  [tex]\sigma_{\bar{x}}[/tex] = 2

We know that for a normally distributed population, the sample mean is also normally distributed.

The sample mean is:

[tex]\mu_{x}[/tex] = μ

where μ is the population mean.

Here, the population is normally distributed with μ = 120

So, the mean of the sampling distribution for any sample size would be, [tex]\mu_{x}[/tex] = 120

As we know the formula for the standard deviation of the sample mean is:

[tex]\sigma_{\bar{x}}[/tex] = σ/[tex]\sqrt{n}[/tex]

where,  [tex]\sigma_{\bar{x}}[/tex]  is the Standard deviation of the sample mean

σ is the population standard deviation

n is the Sample size.

Here, σ = 20

Using above formula of the standard deviation of the sample mean,

For sample size n = 100

[tex]\sigma_{\bar{x}}[/tex] = 20/[tex]\sqrt{(100)}[/tex]

[tex]\sigma_{\bar{x}}[/tex] = 20/10

[tex]\sigma_{\bar{x}}[/tex] = 2

For sample sizen = 16

A baseball team plays in a stadium that holds 52000 spectators. With the ticket price at $9 the average attendance has been 21000. When the price dropped to $7, the average attendance rose to 26000.a) Find the demand function p(x) where x is the number of the spectators. (Assume that p(x) is linear.) p(x)=----------------b) How should ticket prices be set to maximize revenue? The revenue is maximized by charging $ --------per ticket.

Answers

The required demand function and revenue per ticket are p(x) = -0.4 * (x - 21000) + $9 and  $9.

How to find demand function?

a) To find the demand function p(x), we can use the two data points: (21000, $9) and (26000, $7). To find the slope of the demand function, we can use the formula:

slope = (change in price) / (change in attendance)

Plugging in the two data points, we get:

slope = ($9 - $7) / (26000 - 21000) = -$2 / 5000 = -0.4

To find the y-intercept, we can use either data point and the slope we just found. Let's use the first data point:

p(x) = slope * (x - 21000) + $9

Now we have our demand function:

p(x) = -0.4 * (x - 21000) + $9

b) To maximize revenue, we need to find the price that will result in the maximum number of tickets sold. This is equal to the price that corresponds to the peak of the demand function, or the maximum value of x for which p(x) is decreasing. To find this, we can take the derivative of the demand function and set it equal to zero:

simplify 7^8x7^3x7^3/7^9x7^5

Answers

To simplify the expression, we can use the exponent rules of multiplication and division.

The first rule is for multiplying exponential expressions with the same base:

a^m * a^n = a^(m + n)

The second rule is for dividing exponential expressions with the same base:

a^m / a^n = a^(m - n)

Applying these rules to the expression:

7^8 * 7^3 * 7^3 / 7^9 * 7^5

= 7^(8 + 3 + 3) / 7^(9 + 5)

= 7^14 / 7^14

= 7^(14 - 14)

= 7^0

= 1

So the simplified expression is equal to 1

A number cube with faces labeled from 1 to 6 will be rolled once.

The number rolled will be recorded as the outcome.

Give the sample space describing all possible outcomes.

Then give all of the outcomes for the event of rolling a number greater than 5 .

If there is more than one element in the set, separate them with commas.

Answers

The outcomes for the event of rolling a number greater than 5 is 1.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, a number cube with faces labeled from 1 to 6 will be rolled once.

Now, sample space is {1, 2, 3, 4, 5, 6}

Total number of outcomes =6

Number of favourable outcomes =1

Here, the probability is 1/6

Therefore, the outcomes for the event of rolling a number greater than 5 is 1.

Answers

The proportion of temperatures between 17.02°C and 25°C is 0.9539

What is Standard Deviation?

The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

mean = 21.02points and

standard deviation =  points.

Now, using

z= (x-u)/σ

z= 17.02 - 21.02/ 2

z= -2

again, z= (x-u)/σ

z= 25- 21.02 / 2

z= 1.99

So, the proportion is

P(x<108.20)-P(x<104.60)

=P(Z<2.65)-P(Z<2.2)

= 0.9497 -0.0228

=0.9539

Given that f(x)= 2x-1 g(x)=3x and h(x)=x^2+1
Pic is attached below

Answers

The values of the composite functions are g(f(0))= -3 and f(f(2)) = 5

How to evaluate the composite functions

From the question, we have the following parameters that can be used in our computation:

f(x)= 2x-1 g(x)=3x and h(x)=x^2+1

To calculate g(f(0)), we have

f(0)= 2(0)-1 = -1

This means that

g(f(0)) = g(-1)

So, we have

g(f(0)) = 3(-1) = 3

For f(f(2)), we have

f(2)= 2(2)-1 = 3

So, we have

f(f(2)) = 2(3) - 1 = 5

Hence, the composite functions are g(f(0))= -3 and f(f(2)) = 5

When posted overseas to country A at age r, the employees of
a large company are subject to a force of mortality such that, at exact duration
† years after arrival overseas (1 = 0, 1,2, 3,4),

Answers

The probability that an employee posted to country A at age 30 will survive to age 40 if she remains in that country is 2 x 10⁻⁶³

Probability is a mathematical concept that describes the likelihood of a specific event occurring within a set of possible outcomes

Let's start by defining some terms. The force of mortality, also known as the death rate, is the number of deaths per unit time per unit of population.

The probability of survival is the chance that an individual will live past a certain age. In our case, we want to know the probability of surviving from age 30 to age 40 while living in country A.

To calculate the probability of survival, we will use the formula:

[tex]P(x) = e^{-qx}[/tex]

Where P(x) is the probability of survival at age x and qx is the force of mortality at age x.

First, we will calculate the force of mortality for the first five years after arrival in country A using the equation given in the question:

90x+1 = (6 - 1)9x+1

For x = 30, we have:

90(30) + 1 = (6 - 1)9(30) + 1

2701 = 5 * 891 + 1

2701 = 4445 + 1

2700 = 4445

So, q30 = 4445/30 = 148.5

Next, we will use this value to calculate the probability of survival for the first five years in country A:

[tex]P30 = e^{-q3} = e^{-148.5} = 1.2 \times 10^{-64}[/tex]

Since the force of mortality for those who have lived in country A for at least five years is 50% greater than the US Life Tables, 2002, Females, we can calculate the force of mortality for the next 10 years as follows:

qx = 1.5 x qx from US Life Tables

Using the values from Table 3.11, we have:

q31 = 1.5 x 98,424 = 147,636

q32 = 1.5 x 98,362 = 147,543

q33 = 1.5 x 98,296 = 147,444

q34 = 1.5 x 98,225 = 147,338

q35 = 1.5 x 98,148 = 147,222

q40 = 1.5 x 97,500 = 146,250

Finally, we can use these values to calculate the probability of survival from age 31 to age 40:

[tex]P31 = e^{-q31} = e^{-147,636} = 1.3 \times 10^{-65}\\ \\P32 = e^{-q32} = e^{-147,543} = 1.4 \times 10^{-66}\\\\P33 = e^{-q33} = e^{-147,444} = 1.5 \times 10^{-67}\\\\P34 = e^{-q34} = e^{-147,338} = 1.6 \times 10^{-68}\\\\P35 = e^{-q35} = e^{-147,222} = 1.7 \times 10^{-69}\\\\P40 = e^{-q40} = e^{-146,250} = 2.0 \times 10^{-63)}\\\\[/tex]

For those who have lived in country A for at least five years the force of mortality at each age is 50% greater than that of US Life Tables, 2002, Females, at the same age.

1. What rectangle dimensions give the greatest possible area? Explain. (From the rectangle with a perimeter of 20 meters)

2. Suppose the dimensions were not restricted to whole numbers. Would this change your answer? Explain. (same as # 1)

Answers

Problem 1

L = length

W = width

P = perimeter of the rectangle

P = 2L+2W

P = 20

2L+2W = 20

L+W = 10 after dividing everything by 2.

L = 10-W

area = length*width

A = L*W

A = (10-W)*W

A = -W^2 + 10W

Let x replace W for a temporary basis.

If we graphed y = -x^2+10x, then we'd see the highest point occurs at (5, 25). This means a width of 5 meters leads to the largest area of 25 square meters.

The length would be L = 10-W = 10-5 = 5 meters as well.

It turns out that a 5 meter by 5 meter square is the best choice when trying to max out this rectangle's area.

====================================================

Problem 2

The results we got from the previous section was that a 5 by 5 square will max out the area.

If we allowed non-whole numbers into the mix, then it wouldn't change the previous answer. The best choice is still that 5 by 5 square.

The answer only would change if the result of the previous section was some non-integer value.
