What is the value of X in the equation 1/5X—2/3yequals 30when y equals 15

x = 50

Step-by-step explanation:

y = 15

1/5X - 2/3y = 30

1/5x - (2/3 x 15) = 30

1/5x - (10) = 30

1/5x = 30 - 20

1/5x = 10

x = 50

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
