7less than one-fourth of a number equal to 17. what is the number? how do i solve this? pls

Solve it by reversing what is done to the number. You don't need an equation to do that.

17 is 7 less than ...

so adding 7 to 17, making 24, will give you ... one-fourth of the number. If 24 is one-fouth of the number, multiplying 24 by 4 will give you the number. Doing that tells you the number is 96.

You can do the same solution process using an equation.

(1/4)n - 7 = 17 . . . . . 7 less than 1/4 of a number is 17

(1/4)n = 24 . . . . . . . add 7

n = 4·24 = 96 . . . . multiply by 4

The number is 96.

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
