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

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

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 =_____ .

Answer:

The answer to your question is:

(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

Radius

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.

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.

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.
