The quotient of nine times a number and seven

Step-by-step explanation:

Let x be the number.

We have been given a sentence. We are supposed to represent our given information into an algebraic expression.

Nine times a number would be .

We know that the quotient is as one quantity being divided by another.

To get the quotient of nine times a number and seven, we will divide by 7 as:

Therefore, our required quotient would be .

b is the answer that makes most sense

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
