From the diagram of the box plot
A. The IQR for the male's data is approximately 14 - 5 = 9
B. The median for female is 7
The median for male is estimated 10
Difference 10 - 7 = 3.
C. The mean would be better to compare males with females because from the box plot diagram, more males saw the movie than females.
D. The possible reason for the outlier in the data set could be due to more females attending the movie than normal.

Write an equation in slope-intercept form of the line that contains the points in the table.
Answers
Step 1. We are given a table of (x, y) values and we need to select the option that represents the slope calculation.
First, we remember the formula to calculate the slope:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are two points or sets of values given for the line.
Step 2. In the numerator of the slope formula, we have a subtraction between y-values.
In the table, the y-values are:
Therefore, in the numerator of the calculation, we must have a subtraction between two of these numbers. This discards options A, and B.
Step 3. In options C and D we have this:
[tex]C.\frac{9-(-3)}{1-(-2)}[/tex][tex]D.\frac{-3-11}{-2-4}[/tex]In option C, there is a correct subtraction of 9 and -3, but in option D, the correct subtraction would be -3-(-11). Therefore option D is also discarded and the correct answer is C.

Suppose that the corrals are rectangular in shape. The formula of the area of a rectangle is

[tex]\begin{gathered} A_1=50\cdot40=2000 \\ A_2=60\cdot35=2100 \\ A_3=55\cdot45=2475 \\ A_4=65\cdot40=2600 \end{gathered}[/tex]Then, divide each area by its corresponding population,
[tex]\begin{gathered} \frac{A_1}{110}=18.1818\ldots<20 \\ \frac{A_2}{115}=18.2608\ldots<20 \\ \frac{A_3}{125}=19.8<20 \\ \frac{A_4}{110}=20=20 \end{gathered}[/tex]Therefore, the only corral that meets the requirement is corral 4, the answer is option D.
Which proportion describes the relationship between corresponding sides of the triangles?
Answers
Answer: C. WX/RS = 3/6
Explanation:
In the triangle WXY the vertical side is WX, and the horizontal side is XY.
In the triangle RST the vertical side is RS, and the horizontal side is ST.
Since both triangles are similar, this means that their angles have the same measurements, and that there is a propotion or relationship between their sides.
The corresponding sides in this triangle are the following:
WX is a corresponding side with RS
XY is a corresponding side with ST
WY is a corresponding side with RT
Out of the options that we have, the only one that relates two corresponding sides is:
[tex]C\mathrm{}\frac{WX}{RS}=\frac{3}{6}[/tex]This is because as we pointed out, WX ans RS are correponding sides.
Also from the image we see that WX = 3 and RS = 6 wich is correctly placed in option C. Thus C represents the proportion between the two corresponding sides.
Answer: C. WX/RS = 3/6

Find the equation (in terms of xx ) of the line through the points (-4,1) and (3,-2)

First, find the slope of the line that passes through the given points using the slope formula:
[tex]m=\frac{\Delta y}{\Delta x}[/tex]Next, substitute the value of the slope and the coordinates of one of the given points into the slope-intercept form of the equation of a line to find the y-intercept b:

Neve has 12 full boxes of jars of slime and 7 loose jars of slime. If Neve has a total of 187 jars of slime, which equation can be used to find the number of jars in each box?
Answers
Answer:
15 jars in each box
Step-by-step explanation:
linear equation:
12*N + 7
Now we know that Neve has 187 jars in total, then we can write:
12*N + 7 = 187
We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:
12*N + 7 = 187
12*N = 187 - 7
12*N = 180
N = 180/12 = 15

Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probability of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
For P(3)
Number of favourable outcomes = 1
Total number of outcomes = 8
P(3) = [tex]\frac{1}{8}[/tex]
For P(9)
Number of favourable outcomes = 0
P(9) = 0
For P(odd number)
Favourable outcomes = {1, 3, 5, 7}
Number of favourable outcomes = 4
P(odd number) = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]
For P(Number greater than 2)
Favourable outcomes = {3, 4, 5, 6, 7, 8}
Number of favourable outcomes = 6
P(number greater than 2) = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]

Write the numbers that will fill in the eighth row of Pascal’s triangle.
Answers
To answer this question, we're going to use some important properties of the Pascal's triangle.
1) If we number the rows starting at zero, then the kth row has k + 1 elements.
2) If we number the elements on the kth row starting with zero, then the mth element of row k is given by
[tex]\begin{pmatrix}{k} \\ {m}\end{pmatrix}=\frac{k!}{m!(k-m)!}[/tex]Using those two properties, we can answer our question.
We want to know the numbers that will fill in the eighth row, this means our k = 8.
From the first property, we know that we have 9 elements on this row, and they are given by
[tex]\begin{pmatrix}{8} \\ {m}\end{pmatrix}=\frac{8!}{m!(8-m)!},m=0,1,2,\ldots,8[/tex]Plugging each m value on this equation, we have
[tex]\begin{gathered} \begin{pmatrix}{8} \\ {0}\end{pmatrix}=\frac{8!}{0!(8-0)!}=\frac{8!}{8!}=1 \\ \begin{pmatrix}{8} \\ {1}\end{pmatrix}=\frac{8!}{1!(8-1)!}=\frac{8!}{7!}=8 \\ \begin{pmatrix}{8} \\ {2}\end{pmatrix}=\frac{8!}{2!(8-2)!}=\frac{8\cdot7}{2}=28 \\ \begin{pmatrix}{8} \\ {3}\end{pmatrix}=56 \\ \begin{pmatrix}{8} \\ {4}\end{pmatrix}=70 \\ \begin{pmatrix}{8} \\ {5}\end{pmatrix}=56 \\ \begin{pmatrix}{8} \\ {6}\end{pmatrix}=28 \\ \begin{pmatrix}{8} \\ {7}\end{pmatrix}=8 \\ \begin{pmatrix}{8} \\ {8}\end{pmatrix}=1 \end{gathered}[/tex]And those are the values on the eighth row.
