Answer:

Answer: Pct women = 56%; pct men = 44%

Step-by-step explanation:

Pct men = total men/total people * 100

men = 750-420 = 330

Pct men = 330/750 *100 = 11/25 *100 = 0.44 * 100 = 44%

.

Pct women = 100% - 44% = 56%

.

Check the answer by checking the percentage of women.

women = 420

Pct women = 420/750 * 100 = 14/25 = 56%

Correct.

52 miles per hour

Step-by-step explanation:

Answer: 52 MPH

Because as you can see at the (Miles) it is 300 above like 4/60,

and 52 is the best choice

explanation :

6 x 52 = 312

312 is the closest to 300

and if you pick the other ones you get:

42 x 6 = 252 "Not Close"

72 x 6 = 432 "Over 300"

32 x 6 = 192 "Not Close"

The mean and standard deviation of the heights of 10 people were determined using an Excel spreadsheet. If your height is less than the mean, then you are shorter than the average height.

To calculate the mean height, you need to sum up all the heights and divide the total by the number of values. The standard deviation measures the spread of the heights from the mean. You can use the following steps in Excel to calculate these values:

Enter the 10 height values in a column, say column A.

In an empty cell, use the formula "=AVERAGE(A1:A10)" to calculate the mean height.

In another empty cell, use the formula "=STDEV(A1:A10)" to calculate the standard deviation of the heights.

Comparing your height to the mean height of the sample depends on your own height. If your height is greater than the mean, then you are taller than the average height of the 10 people. If your height is less than the mean, then you are shorter than the average height. If your height is equal to the mean, then you have the same height as the average height of the sample.

Regression

A) We can see the graph and through the data that the most indicated form is to find the regression model since there is not much uniformity among the data to describe it as a purely linear model.

Plotting that scatterplot, and generating the equation we know that the equation is:

a) The 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).

b) The 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).

To calculate the confidence intervals for the population proportion, we can use the formula:

Confidence Interval = sample proportion ± margin of error

The margin of error can be calculated using the formula:

Margin of Error = critical value * standard error

where the critical value is determined based on the desired confidence level and the standard error is calculated as:

Standard Error = \(\sqrt{((p * (1 - p)) / n)}\)

Given that the sample proportion (p) is 0.81 and the sample size (n) is 500, we can calculate the confidence intervals.

a. 90% Confidence Interval:

To find the critical value for a 90% confidence interval, we need to determine the z-score associated with the desired confidence level. The z-score can be found using a standard normal distribution table or calculator. For a 90% confidence level, the critical value is approximately 1.645.

Margin of Error = \(1.645 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)

≈ 0.0323

Confidence Interval = 0.81 ± 0.0323

≈ (0.7777, 0.8423)

Therefore, the 90% confidence interval for the population proportion is approximately (0.7777, 0.8423).

b. 95% Confidence Interval:

For a 95% confidence level, the critical value is approximately 1.96.

Margin of Error = \(1.96 * \sqrt{(0.81 * (1 - 0.81)) / 500)}\)

≈ 0.0363

Confidence Interval = 0.81 ± 0.0363

≈ (0.7737, 0.8463)

Thus, the 95% confidence interval for the population proportion is approximately (0.7737, 0.8463).

If the composite functions f(g(x)) and g(f(x)) both equal to x, then the function g is the Inverse function of f.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. 

Let us take the Example.

Suppose f(x)= x/4 and g(x)=4x.

Let x=1

then f(g(x))= f(g(1))=f(4)=1

and g(f(x))=g(f(1))=g(1/4)=1

Here, f(g(x))=g(f(x))=1

Therefore , we can say that f(g(x)) and g(f(x)) are inverse of each other.

Answer:

1) 6 (the answer is 6)

Step-by-step explanation:

First, let's calculate how much the textbooks cost in total: 30 textbooks * $116.00/textbook = $<<30*116=3480.00>>3480.00

Then, let's subtract the cost of the textbooks from the total amount of money the math department has available: $6500.00 - $3480.00 = $<<6500-3480=3015.00>>3015.00

Finally, we can divide the amount of money the math department has left by the cost of each laptop to determine how many laptops they can afford: $3015.00 / $439.00/laptop = 6.83 laptops

Since it's not possible to buy a fraction of a laptop, the math department can only buy 6 laptops. Therefore, the answer is 6, which corresponds to choice (1).

If the quantity bought and sold under a price floor is Q=15, The price floor is $50.

To find the price floor, we need to determine the equilibrium price and compare it to the price floor. At equilibrium, quantity demanded equals quantity supplied, so we can set the demand equation equal to the supply equation and solve for Q:

100 - 2Q = 20 + 2Q

4Q = 80

Q = 20

So, the equilibrium quantity is 20. Since we know that Q=15 under the price floor, we can plug this value into either the demand or supply equation to find the price floor:

P = 100 - 2Q = 100 - 2(15) = $70

Therefore, the price floor is $50, which is lower than the equilibrium price. This means that the price floor is not binding, as the market price will still be determined by the equilibrium.

The cutoff point for the number of minutes at which the customer should be contacted is 696 minutes

To calculate the upper fence for the monthly phone use data, we need to first find the quartiles.

Step 1: Arrange the data in order from smallest to largest

307, 335, 336, 341, 371, 375, 380, 395, 413, 424, 440, 465, 467, 489, 510, 512, 515, 521, 521

Step 2: Find the median

The median is the middle value of the data set. If the data set has an odd number of values, the median is the middle value. If the data set has an even number of values, the median is the average of the two middle values.

In this case, we have an even number of values, so we take the average of the two middle values

Median = (413 + 424)/2 = 418.5

Step 3: Find the first quartile (Q1)

The first quartile is the median of the lower half of the data set. To find Q1, we first find the median of the lower half:

Lower half: 307, 335, 336, 341, 371, 375, 380, 395, 413

Median of lower half = (371 + 375)/2 = 373

Step 4: Find the third quartile (Q3)

The third quartile is the median of the upper half of the data set. To find Q3, we first find the median of the upper half:

Upper half: 424, 440, 465, 467, 489, 510, 512, 515, 521, 521

Median of upper half = (489 + 510)/2 = 499.5

Step 5: Calculate the interquartile range (IQR)

The interquartile range is the difference between Q3 and Q1

IQR = Q3 - Q1 = 499.5 - 373 = 126.5

Step 6: Calculate the upper fence

The upper fence is defined as Q3 + 1.5 × IQR

Upper fence = Q3 + 1.5 × IQR = 499.5 + 1.5 × 126.5 = 695.75

Therefore, the cutoff point for the number of minutes at which the customer should be contacted is 696 minutes (rounded to the nearest minute).

The integers that are closest to the number in the middle in the inequality x < √82 < y are x = 9 and y = 11.

To find the integers x and y that satisfy the inequality x < √82 < y, we need to find the two integers that are closest to the square root of 82.

First, we know that the perfect square that is less than 82 is 81, which is equal to 9². Therefore, we can say that 9 < √82.

Next, we need to find the next closest integer to the square root of 82. To do this, we can calculate the square of 10 and the square of 11, which are 100 and 121, respectively. Since 82 is closer to 81 than to 100, we can say that √82 < 10.5.

Therefore, x = 9 and y = 11 are the integers that satisfy the inequality x < √82 < y.

Answer:

Step-by-step explanation:

The function f(x)=-2(x+2)(x+6) already has an inverse that is a function, and there is no need to restrict the domain.

To restrict the domain of the function f(x)=-2(x+2)(x+6) so that the inverse is a function, we need to consider the concept of a one-to-one function.

A one-to-one function is a function in which each input value (x) corresponds to exactly one output value (f(x)), and vice versa. In other words, there are no repeated output values for different input values.

To ensure that the inverse of f(x) is a function, we need to restrict the domain in a way that eliminates any potential for repeated output values. In this case, we have a quadratic function, and to restrict the domain, we need to identify the values of x that result in repeated output values.

To do this, we can analyze the factors of the quadratic function. The factors of f(x)=-2(x+2)(x+6) are (x+2) and (x+6). Since these factors are linear and distinct, we can conclude that there are no repeated output values.

Therefore, the function f(x)=-2(x+2)(x+6) already has an inverse that is a function, and there is no need to restrict the domain.

The graph of f(x) = -2⁻ˣ is given as attached.

To graph the function f(x) = -2⁻ˣ, we can follow these steps:

1. Choose a set of x-values to plot on the x-axis. Since the function has an exponent that involves negative powers of 2, we should choose values that are evenly spaced on the x-axis, such as -3, -2, -1, 0, 1, 2, and 3.

2. Substitute each x-value into the function to find the corresponding y-value. For example, when x = -3, we have f(-3) = -2⁻³ = -1/8. Similarly, we can find the y-values for the other x-values we chose.

3. Plot the points (x, y) on the graph. Make sure to label the axes and use a ruler or graphing software to ensure accuracy.

4. Connect the points with a smooth curve to show the shape of the function between the plotted points. Since the function has a negative exponent, it approaches zero as x gets larger, so the curve should approach the x-axis as it moves to the right.

The resulting graph should show a decreasing curve that gets closer and closer to the x-axis, without ever touching it, as x gets larger.

Note that the values of y for each x are:

When x = -3, y = -1/8

When x = -2, y = -1/4

When x = -1, y = -1/2

When x = 0, y = -1

When x = 1, y = -2

When x = 2, y = -4

When x = 3, y = -8

The deflection angle of light by the white dwarf star is approximately \(\(0.00108 \times 206,265 = 223.03\)\)arcseconds (rounded to two decimal places).

To calculate the deflection angle of light by a white dwarf star, we can use the formula derived from Einstein's theory of general relativity:

\(\[\theta = \frac{4GM}{c^2R}\]\)

where:

\(\(\theta\)\) is the deflection angle of light,

G is the gravitational constant \((\(6.67430 \times 10^{-11} \, \text{m}^3 \, \text{kg}^{-1} \, \text{s}^{-2}\)),\)

M is the mass of the white dwarf star,

c is the speed of light in a vacuum \((\(299,792,458 \, \text{m/s}\)),\) and

(R) is the radius of the white dwarf star.

Let's calculate the deflection angle using the given values:

Mass of the white dwarf star, \(\(M = 1.2 \times \text{solar mass}\)\)

Radius of the white dwarf star, \(\(R = 0.0088 \times \text{solar radius}\)\)

We need to convert the solar mass and solar radius to their respective SI units:

\(\(1 \, \text{solar mass} = 1.989 \times 10^{30} \, \text{kg}\)\(1 \, \text{solar radius} = 6.957 \times 10^8 \, \text{m}\)\)

Substituting the values into the formula, we get:

\(\[\theta = \frac{4 \times 6.67430 \times 10^{-11} \times 1.2 \times 1.989 \times 10^{30}}{(299,792,458)^2 \times 0.0088 \times 6.957 \times 10^8}\]\)

Evaluating the above expression, the deflection angle \(\(\theta\)\) is approximately equal to 0.00108 radians.

To convert radians to arcseconds, we use the conversion factor: 1 radian = 206,265 arcseconds.

Therefore, the deflection angle of light by the white dwarf star is approximately \(\(0.00108 \times 206,265 = 223.03\)\)arcseconds (rounded to two decimal places).

Hence, the deflection angle is approximately 223.03 arcseconds.
