If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function".

C = {(9, 1) (8, -3) (7, 5) (-5, 3)}

not a function
Domain: {9, 8, 7, -5} Range: {1, -3, 5, 3}

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

What is the value of x in the diagram below?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
