Answer:
E(M) = 23/3
Var(M) = 53/9.
Step-by-step explanation:
There are three possible values for M: 4, 6, and 10.
.
That's six unique combinations in total. If the balls are drawn randomly, the probability for getting each combination shall be equal. That is:
.
Consider the formula for the expected value of a discrete random variable:
.
Formula for the variance of a discrete random variable (note that this formula can take many other forms):
.

Answer:
152
ΔY = 436 - 132 =304
Δ X = 6-4 = 2
ΔY/X = 304/2 = 152

Answer:
828
Step-by-step explanation:
The expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)
and 2(-0.5(1.7))
<h3>Distributive law of expansion</h3>
Given the expression below;
-0.5 (1.7 + 1.7)
According to the distributive law;
A(B+C) = AB + AC
Expand
-0.5(1.7) + (-0.5)(1.7)
-0.5(1.7) - 0.5(1.7)
2(-0.5(1.7))
Hence the expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)
and 2(-0.5(1.7))
