What is the value of x?

__units

x = 28 units

Step-by-step explanation:

We need to find the value of x.

The given triangles are similar triangles.

So, the ratio of corresponding sides are same.

Solving this equation we can find value of x.

So, we get x = 28

So, we get the value of x: x = 28 units

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
