math is my worst subject

2

Step-by-step explanation:

Step 1:

- 5x + 4 = 3x - 12       Equation

Step 2:

4 = 8x - 12         Add 5x on both sides

Step 3:

16 = 8x       Add 12 on both sides

Step 4:

x = 16 ÷ 8       Divide

x = 2

Hope This Helps :)

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
