Find two numbers whose square increased by 15 equals 8 times the number.

5 and 3

So we let the number take the letter b, anc the expression of the question is:

b^2+15=8×bso

b^2+15=8b

Then we take the 8b to the other side of the equal sign so that it becomes...

b^2+15-8b=0

Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...

From there we work out to get two different numbers...either b-5=0

b=5

Or b-3=0

b=3

So the two numbers are 5 and 3

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
