Of the following sets, which represents a function? (1 point)

Situation A = {student's name, all the colors that the student likes}

Situation B = {student's name, the student's favorite math teacher}

Group of answer choices

Both A and B

Only B

Neither A nor B

Only A

Answers

Answer 1

Answer: Only B

============================================

Explanation:

For situation A,

x is the input and it represents the student's name. y is the output and it represents the colors the student likes.

The pairing (x,y) tells us what a certain student likes in terms of color.

For example, the point (Allen, Red) tells us that Allen likes the color red. We could also have (Allen, Green) telling us he also likes green. Because the input "Allen" maps to more than one output, this means situation A is not a function. A function is only possible if any given input maps to exactly to one output. The input must be in the domain. The domain in this case is the set of all students in the classroom.

In contrast, Situation B is a function because a student will only have one favorite math teacher. I'm interpreting this to mean "number one favorite" and not a situation where a student can select multiple favorites.

An employee at a health club takes home an after-tax salary of $950 every two weeks. If the tax rate is 8%, how much does the employee make every two weeks before taxes? Round your answer to the nearest dollar.Write an equation and explain how you used it to find your answer.

Answers

Answer:

$1032.60

Step-by-step explanation:

Given data

salary = $950 every two weeks

tax rate = 8%

let the initial pay be x

and let the pay after tax deduction be p

p= x-8/100x

Hence the equation for his pay is

[tex]p=x-0.08x-------------1[/tex]

subsitute

950=x-0.08x

950= 0.92x

divide both sides by 0.92

x= 950/0.92

x=$1032.60

The employee make $1032.60 every two weeks before taxes
