Eric has saved $587.46 to but a used car. the car he wants costs $675. how much more money does he need? write an equation. then solve.

He needs 87.54.

Step-by-step explanation:

675.00 - 587.46 = 87.54

the answer is $87.54. Supposed that the value of x is $87.54, write it as:

$675 - $587.46 = x

then solve, rewrite the factors and write the answer.

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
