Step-by-step explanation:

This question has missing details because the number of video games is not stated;

However, you'll arrive at your answer if you follow the steps I'll highlight;

The question requests for the number of arrangement; That means we're dealing with permutation

Let's assume the number of video games is n;

To arrange n games, we make use of the following permutation formula;

\(^nP_n = \frac{n!}{(n-n)!}\)

Simplify the denominator

\(^nP_n = \frac{n!}{0!}\)

0! = 1; So, we have

\(^nP_n = \frac{n!}{1}\)

\(^nP_n = n!\)

Now, let's assume there are 3 video games;

This means that n = 3

\(^3P_3 = 3!\)

\(^3P_3 = 3 * 2 * 1\)

\(^3P_3 = 6\ ways\)

So, whatever the number of video games is; all you have to do is; substitute this value for n;

Answer: 45

Step-by-step explanation:

The total profit in all was \(1040-900=\$ 140\).

The total profit per pizza was \((0.50)(8)=\$4\).

This means they sold \(\frac{140}{4}=35\) pizzas.

Adding this to the 10 pizzas held back, there were \(35+10=45\) pizzas in the original order.

Floyd needs 33 matches to make a rectangle with a length of 20 matches.

To find out how many matches Floyd needs to make a rectangle with a length of 20 matches, we can observe a pattern in the given information.

From the given data, we can see that as the length of the rectangle increases by 4 matches, the number of matches used increases by 8. This means that for every additional 4 matches in length, Floyd requires 8 more matches.

Using this pattern, we can calculate the number of matches needed for a rectangle with a length of 20 matches.

First, we need to determine the number of 4-match increments in the length of 20 matches. We can do this by subtracting the starting length of 3 matches from the target length of 20 matches, which gives us 20 - 3 = 17.

Next, we divide the number of 4-match increments by 4 to determine how many times Floyd needs to add 4 matches. In this case, 17 ÷ 4 = 4 with a remainder of 1.

Since Floyd requires 8 matches for each 4-match increment, we multiply the number of increments by 8, which gives us 4 × 8 = 32 matches.

Finally, we add the remaining matches (1 match in this case) to the total, resulting in 32 + 1 = 33 matches needed to reach a length of 20 matches.

______ allows data to be transmitted by the computer in ahu-man-of riendly from

The coordinates of points C, E and G are respectively; C(-0.75, 8.5),  E(3.75, 7.5) and H(7.5, 6)

We are told that the line AB is divided into 7 equally spaced points labelled as C, D, E, F, G, H and I.

Now, coordinates of A and B are; A(-3, 9) and B(9, 5)

Since they are equally spaced, then it means that point F is the midpoint of the line. If (x, y) is the coordinate of F, then;

x, y = (-3 + 9)/2, (9 + 5)/2

x, y = (6, 7)

H is the midpoint of FB. Thus;

H(x, y) = (6 + 9)/2, (5 + 7)/2

H(x, y) = (7.5, 6)

D is midpoint of A and F. Thus;

D(x, y) = (-3 + 6)/2, (9 + 7)/2

D(x, y) = (1.5, 8)

E is midpoint of F and D. Thus;

E(x, y) = (1.5 + 6)/2, (8 + 7)/2

E(x, y) = (3.75, 7.5)

C is midpoint of D and A. Thus;

We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.

A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.

This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.

A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

The angles of rotation for a regular pentagon are:

A Regular Pentagon has five equal sides and five equal angles.

Since the sum of the interior angles of a polygon with n sides is given as:

(n-2) x 180°, then we have:

(5-2) x 180 = 540°.

Note that n = sides of pentagon which is 5

Since all angles in a regular pentagon are equal, each angle measures (540/5) = 108°.

The angles of rotation for a regular polygon are given by the formula 360/n, where n is the number of sides.

Therefore, the angles of rotation for a regular pentagon is:

360/5 = 72°,

Any other angles will be in the multiple of 72. Therefore we have:

We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

The mean is a measure of central tendency that represents the average value of a set of numbers. It is also called the arithmetic mean or simply the average.

We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

The mean and the median are two different measures of central tendency, and they can have different values depending on the distribution of the data. In general, if a data set is symmetric and bell-shaped, the mean and the median are close to each other. However, if the data set is skewed, the mean and the median may be different.

For example, consider the following two data sets:

Set 1 data: 1, 2, 3, 4, and 5.

The median is 3.

The mean is (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3.

Data set 2: 1, 2, 3, 4, 10

The median is 3.

The mean is (1 + 2 + 3 + 4 + 10) / 5 = 20 / 5 = 4.

In data set 1, the mean is the same as the median. In data set 2, the mean is greater than the median because the value 10 is an outlier that pulls the mean up.

Therefore, without additional information about the distribution of the data, we cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

Answer:

\(\textsf{c) \quad $1 \frac{1}{2}$ cups of broccoli per 1 lb of beef}.\)

Step-by-step explanation:

Given information:

Create a ratio of pounds of beef to cups of broccoli, where x is the number of cups of broccoli to one pound of beef:

\(\implies \dfrac{3}{4}: \dfrac{9}{8}=1:x\)

\(\implies \dfrac{\frac{3}{4}}{\frac{9}{8}}=\dfrac{1}{x}\)

Cross multiply:

\(\implies \dfrac{3}{4}x=\dfrac{9}{8}\)

\(\implies x=\dfrac{9}{8} \div \dfrac{3}{4}\)

To divide fractions, flip the second fraction (make the numerator the denominator, and the denominator the numerator) then multiply it by the first fraction:

\(\implies x=\dfrac{9}{8} \times \dfrac{4}{3}\)

\(\implies x=\dfrac{9 \times 4}{8 \times 3}\)

\(\implies x=\dfrac{36}{24}\)

\(\implies x=\dfrac{3 \cdot \diagup\!\!\!\!\!\!12}{2 \cdot \diagup\!\!\!\!\!\!12}\)
