# The fifth period Coordinate Algebra class received their quiz grades back from Mr. Smith today. The students were offered a chance for five quiz points if they constructed a box and whisker plot using the 20 quiz scores. As Mr. Smith's teaching assistant, you are asked to create a solution key for the box and whisker plot. Mr. Smith asked you to report back to him tomorrow morning with the Q1, Q3, and IQR.Use the set of student quiz scores to complete your calculations. Complete your work in the space provided or upload a file that can display math symbols if your work requires it.Turn in the Q1, Q3, and IQR and all of the necessary steps that you took to make your calculations. Fifth Period Quiz Grades: 100, 96, 58, 95, 60, 95, 69, 88, 71, 95, 85, 93, 91, 78, 78, 85, 86, 98, 87, 100

Answer: First, we need to put the numbers in order...
58,60,69,71,78,78,85,85,86,87,88,91,93,95,95,95,96,98,100,100
and since there is an even number of numbers (20), we need to find the 2 middle numbers and divide them by 2 to find the median (Q2)
Q2 (the median) = (87 + 88) / 2 = 175/2 = 87.5
now we take all the numbers below 87.5...and find the median (middle number) and that number will be Q1...there is 2 middle numbers...so we add them and divide by 2
Q1 = (78 + 78) / 2 = 156/2 = 78
now we take all the numbers after 87.5....and find the median...there will be 2 numbers, so we add them and divide by 2..that wil be Q3
Q3 = (95 + 95) / 2 = 190/2 = 95

So in summary :
Q1 = 78

A circle is centered at the point (5, -4) and passes through the point (-3, 2). The equation of this circle is (x +_____)2 + (y +____)2 =_____ .

(x - 5)² + (y + 4)² = 10²     or         (x - 5)² + (y + 4)² = 100

Step-by-step explanation:

Data

Center (5, - 4)

Point ( -3 , 2)

Formula

d = √ ((x2- x1)² + (y2 - y1)²)

(x - h)² + (y - k)² = r²

Process

d = √ ((-3 - 5)² + (2 + 4)²)

d = √ ((-8)² + (6)²)

d = √ 64 + 36

d = √100

d = 10 units

Circle

(x - 5)² + (y + 4)² = 10²

(x - 5)² + (y + 4)² = 100

Jack buys a bag of 5 apples each equal in size he eat 1/2 of one Apple what fraction did he eat

You have  apples left.
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate  of it.
Jack ate  of an apple in 5 apples.
If you say that Jack ate  of 3 apples, then he ate  apples. So there isn't any difference when he ate  of an apple.

Step-by-step explanation:

A membership committee of three is formed from four eligible members. Let the eligible members be represented by A, B, C, and D. The possible outcomes include S = {ABC, ABD, ACD, BCD}. Which statements about the situation are true?

A membership committee.

The committee is formed by the three that are eligible members. These members are represented by the letter as A, B, C, and D. This stated that outcomes of the three remember maybe S = {ABC, ABD, ACD, BCD}.

Hence the answer is there are four ways to choose in the committee. There are thee a person D is included and person B and C are not included.

• As per the statement, the given outcomes that are S equal to {ABC, ABD, ACD, BCD} which is given tells about that there are four ways that the committee members can be considered.
• The are other three ways also that lead to the choosing of the member of the committee. Person B and C are not necessary to be included in the committee.
• Hence options 1, 2, 3 are correct or true.

Step-by-step explanation:

The given sample space of S is  = {ABC, ABD, ACD, BCD},

And from this sample space it can be deduced that;

(a) There can be four ways to choose the committee.

(b) There can be three ways in which person D is always included.

(c) And if persons B and C are necessarily be  included, then there are two ways to form the committee.
