Answer:

33 pages per hour

Step-by-step explanation:

1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.

2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: \(\frac{x}{11} =3\).

3. (Solving x/11 = 3)

Step 1: Multiply both sides by 11

Therefore, Penny read 33 pages per hour.

78% of the students in the sample stated they would prefer to start their own business rather than work for someone else.

The sample proportion is a statistic that measures the proportion of individuals in a sample who have a particular characteristic of interest. In this case, we are interested in the proportion of college students who stated they would prefer to start their own business rather than work for someone else.

The sample proportion can be calculated as the number of individuals in the sample who have the characteristic of interest (in this case, preferring to start their own business) divided by the total number of individuals in the sample. Using the information provided in the question, we have:

Number of individuals in the sample who prefer to start their own business: 78

Total number of individuals in the sample: 100

So the sample proportion is:

sample proportion = 78/100 = 0.78

Rounding this to two decimal places, we get:

sample proportion ≈ 0.78

Answer: y = -3/5x - 6

Step-by-step explanation:

There are a few equations that can be used for this, but the simplest one would be y = mx + b

We are given:

y = -3

m = -3/5 (slope)

x = -5

b = ?

Our equation is this, we are solving for b

==> -3 = -3/5 ( -5) + b

==> -3 = -3/5 ( -5) + b ( multiply the brackets)

==> -3 = 3 + b ( subtract 3 to both sides)

==> -6 = b

Now we can make the desired equation in slope intercept form;

y = -3/5x - 6

Domain of the radical function of the form f(x) = √(ax + b) + c is given by the solution of the inequality ax + b ≥ 0 and the range is the all possible values obtained by substituting the domain values in the function.

We know that the general form of a radical function is,

f(x) = √(ax + b) + c

The domain is the possible values of x for which the function f(x) is defined.

And in the other hand the range of the function is all possible values of the functions.

Here for radical function the function is defined in real field if and only if the polynomial under radical component is positive or equal to 0. Because if this is less than 0 then the radical component of the function gives a complex quantity.

ax + b ≥ 0

x ≥ - b/a

So the domain of the function is all possible real numbers which are greater than -b/a.

And range is the values which we can obtain by putting the domain values.

the volume of the solid generated when the region R, bounded by the graphs of y = x, y = e^2, and the line x = 1, is revolved about the line y = 1, is approximately 0.339 cubic units (option A).

To find the volume, we will use the method of cylindrical shells. Each cylindrical shell is formed by rotating a vertical strip of the region about the axis of rotation (y = 1). The height of each shell is the difference between the upper and lower curves, which is (e^2 - x). The radius of each shell is the distance between the axis of rotation (y = 1) and the y-coordinate, which is (1 - x).

Integrating the volume element 2π(1 - x)(e^2 - x) dx from x = 0 to x = 1, we can calculate the total volume. Evaluating this integral gives us an approximate volume of 0.339 cubic units. Therefore, the correct option is A.

The statement "If x = -10, then x² = 100" is false. When we square -10, we get 100, so the correct statement would be "If x = -10, then x² = 100."

The statement that is NOT true is:

If x = -10, then x² = 100.

The other three statements are all true:

If x² = 100, then x = 10.This is true because the square root of 100 is ±10, and when we take the square root, we consider the positive square root, which is 10.

If x = 10, then x² = 100. This is also true because when we square 10, we get 100.The statement x² = 100 if and only if x = 10 or x = -10 is true.

This statement is based on the fact that the square root of 100 is ±10, so when we square either 10 or -10, we get 100.

If the inter-quartile range is 25 and SD 15 marks then For the new set of marks, a) the mean is 60, b) the median is 55.

By subtracting 10 from all the marks, we shift the entire distribution downward by 10 units. Since the mean represents the average value, subtracting 10 from each mark will decrease the mean by 10. Therefore, the new mean is 70 - 10 = 60.

The median represents the middle value in a sorted list of marks. Since we only subtract a constant value, the order of the marks remains unchanged, and the relative positions of the marks do not shift. Thus, subtracting 10 from all the marks will also decrease the median by 10. Therefore, the new median is 65 - 10 = 55.

It is important to note that subtracting a constant from all the marks does not affect the interquartile range (IQR) or the standard deviation (SD) because these measures are based on the relative positions and deviations of the marks rather than their absolute values.

The acceleration of a particle moving along a straight line is given by a = 6t. If, when t = 0, its velocity, v, is 1 and its position, s, is 3, then at any time t: s = t³ + t + 3. The correct answer is C.

We know that acceleration is the derivative of velocity and velocity is the derivative of position. So, integrating the given acceleration a = 6t with respect to time we get, v = 3t² + C1 where C1 is a constant of integration.

Given that when t = 0, v = 1, so substituting these values in the above equation, we get 1 = 3(0)² + C1, which implies C1 = 1.

Now, integrating the velocity v = 3t² + 1 with respect to time we get, s = t³ + t + C2 where C2 is a constant of integration.

Given that when t = 0, s = 3, so substituting these values in the above equation, we get 3 = 0³ + 0 + C2, which implies C2 = 3.

Therefore, the position of the particle at any time t is given by s = t³ + t + 3.

Step-by-step explanation:

Fame age be x and sister's age = y

Five years ago:

Fame's age = x - 5

His sister's age = y -5

\(x -5 =\dfrac{1}{6}*(y-5)\\\\\)

Multiply the entire equation by 6

\(6*(x-5)=6*\dfrac{1}{6}(y-5)\\\)

6x- 6*5  = y-5

6x - 30 = y - 5

6x  -30 + 5 = y

y = 6x - 25--------------(I)

Three year after:

Fame's age = x + 3

His sister's age = y + 3

2*(x +3) = y + 3

2x + 6   = y + 3

2x + 6 -3 = y

y = 2x + 3 -------------(II)

Substitute y = 6x - 25 in equation (II)

6x - 25 = 2x + 3

Add 25 to both sides

6x  = 2x + 3 + 25

6x  = 2x + 28

Subtract 2x from both sides

6x - 2x = 28

       4x = 28

Divide both sides by 4

x = 28/4

x = 7

Substitute x = 7 in equation (I)

y =6x - 25

y = 6*7 - 25

  = 42 - 25

y = 17

Fame's age = 7 years

His sister's age = 17 years

4) Let the distance between X and Y be D

Time take by Wie = distance÷ speed

                             \(= \dfrac{D}{75}\)

Time taken by Wary = distance ÷ speed

                                  \(=\dfrac{D}{80}\)

Time difference = 10 minutes.

As Wary drives in high speed that Wie, he takes less time

\(\dfrac{D}{75}-\dfrac{D}{80}= \dfrac{10}{60}\\\\\)

LcM = 1200

\(\dfrac{16D}{75*16}-\dfrac{15D}{85*15}=\dfrac{1}{6}\\\\\\\dfrac{16D-15D}{1200}=\dfrac{1}{6}\\\\\\\dfrac{D}{1200}=\dfrac{1}{6}\\\\\\D=\dfrac{1}{6}*1200\\\\\\\)

The Mae takes the absolute values of the forecast errors to ensure they don't cancel each other out.

By considering only the magnitude of the errors, the MAE (Mean Absolute Error) provides a measure of the average deviation between forecasts and actual values.

To ensure that forecast errors don't cancel each other out, the Mean Absolute Error (MAE) calculation involves taking the absolute values of the errors. The MAE is a commonly used metric to measure the accuracy of a forecasting model.

Forecast errors represent the differences between predicted values and actual values. These errors can be positive or negative, depending on whether the forecast overestimates or underestimates the actual value. By taking the absolute values, the direction of the error is disregarded, and only the magnitude of the deviation is considered.

By summing up the absolute values of all the forecast errors and dividing by the number of observations, the MAE provides an average measure of how far the forecasts deviate from the actual values. It allows for the evaluation of the average absolute magnitude of the errors without considering their direction.

In summary, the Mean Absolute Error (MAE) takes the absolute values of the forecast errors to ensure they don't cancel each other out. This approach allows for a measurement of the average deviation between forecasts and actual values by considering only the magnitude of the errors.

A U.S. dollar can buy approximately 0.21 Swiss francs (rounded to two decimal places). Thus, the answer is option d) 0.21.

To determine how much Swiss francs a U.S. dollar can buy, we need to use the given exchange rates between different currencies.

Given:

1 ounce of gold costs 15 U.S. dollars and 14.3028 Italian lira.

1 ounce of silver costs 0.7302 Italian lira and 0.1605 Swiss francs.

Let's calculate the exchange rate between the U.S. dollar and the Swiss franc using the given information:

1 ounce of silver = 0.7302 Italian lira

1 ounce of silver = 0.1605 Swiss francs

To find the exchange rate between the Italian lira and the Swiss franc, we can divide the price of 1 ounce of silver in Swiss francs by the price of 1 ounce of silver in Italian lira:

Exchange rate: 0.1605 Swiss francs / 0.7302 Italian lira

Simplifying this, we get:

Exchange rate: 0.2199 Swiss francs / 1 Italian lira

Now, let's find the exchange rate between the U.S. dollar and the Italian lira:

1 ounce of gold = 15 U.S. dollars

1 ounce of gold = 14.3028 Italian lira
