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):
.
The value of 4 in 34,258 is 10 times the value of the 4 in 47,163
(-1,8) is the correct answer I’m pretty sure
Answer:
(4, 9) and (-10, -8)
Step-by-step explanation:
The standard form of linear equations is Ax + By = C where A and B ≠ 0, and A is non-negative.
Therefore, the correct answer is A) 6x - 7y = 8
