Expand & simplify 6 ( 4 c + 2 ) − 6 ( 2 c − 2 )

Step-by-step explanation:

The first step, is to distribute. Multiply 6 to 4c and 2. Also multiply -6 to 2c and 2. After the distribution, you'd end up with 24c + 12 - 12c +12.

After this, the second step is to combine like terms. We know that 24c and -12c both have the variable of c. So, 24c - 12c=12c. We also know that 12 and 12 are also alike, so 12 + 12=24.

Now, we are left with the answer of 12c + 24.

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
