The correct option is B. The Wolverines' distribution is negatively skewed, but the Panthers' distribution is symmetric.
When is data symmetric for a given box plot?Data is symmetric if the median is in the mid of the box plot and the box is mid to the line connecting both whiskers.
The box plot showing scores for the Panthers basketball team has the median shown by a vertical line dividing the box into 2 equal halves.
Also, both whiskers on either side are relatively equal which shows that the data set for bulldogs is symmetric.
On the other side, the box plot for wolverine shows the median closer to the upper quartile.
That shows that the data set for team Wolverines' distribution is negatively skewed.
The correct option is B. The Wolverines' distribution is negatively skewed, but the Panthers' distribution is symmetric.

Step-by-step explanation:
The completed equation should say:
y = -3x + 4
This is slope-intercept form of the equation. It's a fill-in-the-blank equation. You put the slope in the first blank and the y-intercept in the second blank. Your math program put the negative sign in and it does need to be there. To find the slope, look at the points on the line. To get from one point to the next you go DOWN3 and over 1. DOWN3 and OVER1 is the slope -3/1, which is -3. This number goes beside (in front of) the x. The line crosses the y-axis at 4, fill that in at the end of the equation (the second blank).
The equation for the line is

Avani has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $17, before discount and tax. After the discount, and before tax, the price is $15.64. Find the percent discount.
The percentage discount on the item will be equal to 8%.
What is the percentage?
The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
Given that:-
Price of the item before tax and discount = $17After discount and before tax price is = $15.64The percentage of the discount will be calculated as:-
Percentage discount = ( 17 - 16.64 ) / ( 17 )
Percentage discount= ( 1.36 ) / ( 17 )

Answer:
1. 85 people were surveyed
Determine the Angle Measures
The angles are p=67°, q=15°, x=82°, y=81°, s=28° and m=72.5°.
For the given figures we need to find the unknown angles.
In the first figure to find angle p first apply the angle sum property to the triangle.
That is, 82°+31°+p=180° (∵ Sum of interior angles of a triangle is 180°)
⇒p=67°.
p=67° is a vertically opposite angle to the other triangle.
To find q:
67°+98°+q=180°
⇒q=15°.
In the second figure to find angles x and y apply the angle sum property to the triangle.
That is, 28°+(53°+x)+17°=180°
⇒98°+x=180°
⇒x=82°.
To find y:
x+y+17°=180°
⇒82°+y+17°=180°
⇒y=81°
In the third figure to find angles x and y apply the angle sum property to the triangle.
That is, 100-x+30+4x+7x=180°
⇒10x=80°⇒x=10°.
Now the angles of the triangle are 100-10=90°, 30+4x=70°
y=90°+70°=160° (∵Exterior angle is equal to the sum of two opposite interior angles).
In the 4th figure, to find angle 's' use the isosceles triangle concept.
That is, s+76°+76°=180° (∵In isosceles triangle base angles are equal)
⇒s=28°
In the 5th figure, to find angle 'm' use the isosceles triangle concept.
That is, 35°+m+m=180° (∵In isosceles triangle base angles are equal)
⇒2m=145°
⇒m=72.5°
Hence, the angles are p=67°, q=15°, x=82°, y=81°, s=28° and m=72.5°.

If the set U = {all positive integers} and set A = {x|x ∈ U and x is an odd positive integer}, which describes the complement of set A, Ac?
Ac = {x|x ∈ U and is a negative integer}
Ac = {x|x ∈ U and is zero}
Ac = {x|x ∈ U and is not an integer}
Ac = {x|x ∈ U and is an even positive integer}
Answer: Choice D) set of even integers
=======================================================
Explanation:
U = universal set = {all positive integers} = {1, 2, 3, 4, 5, ...}
A = {stuff in set U that is odd} = {1, 3, 5, 7, 9, ...}
[tex]A^c[/tex] = {stuff in set U but NOT from set A} = {2, 4, 6, 8, ...}
[tex]A^c[/tex] = {set of even numbers from set U}
In set theory, the complement is simply the complete opposite. If the number 7 is found in set A for instance, then 7 is not going to live in the complement [tex]A^c[/tex]
The opposite of the odd numbers is the set of even numbers.
Therefore, we go for choice D as our final answer.
Side note: if we union set A with its complement [tex]A^c[/tex] then we get the universal set as a result. [tex]A \cup A^c = \text{universal set} = \text{set of all positive integers}[/tex]
The solution is Option D.
Ac = {x|x ∈ U and is an even positive integer} where Ac represents the complement of set A
What is union and intersection of sets?
The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the set U be = {all positive integers}
So , the values of set U = { 1 , 2 , 3 , 4 , 5 .. }
And , let the set A = {x|x ∈ U and x is an odd positive integer}
So , the value of set A = { 1 , 3 , 5 , 7 , ... }
And , the complement of set A is Ac
The value of set Ac is all the even positive odd integers
So , the value of set Ac = { 2 , 4 , 6 , 8 .. }
Therefore , the value of set Ac = { 2 , 4 , 6 , 8 .. }
Hence , the set Ac = {x|x ∈ U and is an even positive integer}

The cost of the toy is expressed by the function y = 3x + 5, where x is the number of toys. If Peter bought 8 toys, find the cost of the toys.
Answer: If Peter bought 8 toys, the cost of the toys will be 29.
From the equation, y = 3x + 5, they have given the value of x as eight. So if we put eight in the equation and solve it, we will get the value of y. I believe there are some errors in the question as it doesn't specify that y is the cost. Also cost requires some sort of unit, which is not given in the context. I can't really tell if it is dollars or rubles or pounds etc. So I just gave it as the way it is. Since no other clues are given, this is most likely it.

When 7/11 is written as a decimal, what is the sum of the first 20 digits after the decimal point? Pls Help
There's a neat trick to finding the rational form of a repeating decimal number. Take for instance [tex]x=0.123123123\ldots[/tex]. Then
[tex]x = 0.123123123\ldots \\\\ \implies 1000x = 123.123123\ldots \\\\ \implies 1000x - x = 123.123123\ldots - 0.123123\ldots \\\\ \implies 999x = 123 \\\\ \implies x = \dfrac{123}{999}[/tex]

[tex]x = \dfrac7{11}[/tex]
Multiply the numerator and denominator by 9,

A line with slope 2 passes through the point (2, -4). Find the coordinates of another point on the line.
Answer:
(3, -2)
Step-by-step explanation:
We can view slope as: [tex]\frac{rise}{run}[/tex] (rise / run)
"rise" is the change in y from one point to another
"run" is the difference in x from one point to another
So, if the slope of a line is 2, it rises 2 every time it runs 1 (2 = 2/1)
So, we can find another point on the line by adding 2 to the y-value, and adding 1 to the x-value.

Find the equation of the line passing through the points -2x+1 (8,2)
The line that passes through (-2, 1) and (8, 2) is:
y = (1/10)*x + 12/10
How to find the equation of the line?I assume you want to find the equation of the line that passes through (-2, 1) and (8, 2).
A general linear equation is written as:
y = a*x + b
If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case, we know that it passes through (-2, 1) and (8, 2), then:
[tex]a = \frac{2 - 1}{8 - (-2)} = 1/10[/tex]
Then the line is:
y = (1/10)*x + b
To find the value of b, we use one of the given points, for example if we use (8, 2), it means that when x = 8, we must have y = 2.
2 = (1/10)*8 + b
2 - 8/10 = b
20/10 - 8/10 = b
12/10 = b

You are riding along a straight river from east to the west at speed of 160m/m. At a given time, you will see the bearing of a church on the other parallel road is N 70 degrees W, and 4 minutes later the bearing is N 56 degrees W. What is the width of the river? (Round your answer to two decimal points)
Using the given information, the width of the river is 505.96 m
Bearing and DistancesFrom the question, we are to determine the width of the river
Consider the given diagram,
Let F be the first position of the biker
S be the second position
and C be the position of the church
First, we will determine the distance covered from F to S
Speed = 160m/min
Time = 4 minutes
Using the formula,
Distance = Speed × Time
Distance covered = 160 × 4
Distance covered = 640 m
That is, /FS/ = 640 m
Now, consider ΔFSC
∠F = 90° - 70° = 20°
∠S = 90° + 56° = 146°
and ∠C = 180° - 20° - 146° = 14°
By the Law of Sines
[tex]\frac{/FC/}{sin\ S}= \frac{/FS/}{sin\ C}[/tex]
∴ [tex]\frac{/FC/}{sin\ 146^\circ}= \frac{640}{sin\ 14^\circ}[/tex]
[tex]/FC/ =\frac{640 \times sin \ 146^\circ}{sin \ 14^\circ}[/tex]
/FC/ = 1479.33 m
Now,
By SOH CAH TOA
[tex]cos \ 70^\circ = \frac{d}{/FC/}[/tex]
NOTE: d is the width of the river
∴ d = /FC/ × cos70°
d = 1479.33 × cos70°
d = 505.96 m
Hence, the width of the river is 505.96 m

Find the value of y.
Answer:
y = 5
Step-by-step explanation:
Since the lines are parallel, same side interior angles are supplementary.
That allows us to solve for x.
7x + 17 + 5x - 5 = 180
12x = 168
x = 14
The angles 23yand 5x - 5 are supplementary, so the sum of the measures equals 180°.
23y + 5x - 5 = 180
We already know that x = 14.
23y + 5(14) - 5 = 180
23y = 115
