Since you can factor 5 out of both 45c and 10d, the expression will be 5(9c+2d)
5(9c+2d)
=)=)=)
Divide both sides by 2, which equals 7, then to get x alone, divide by 5 which gives you 1.4.
Answer: 4
Step-by-step explanation:
Given the following :
P = probability of success = 0.5
n = number of trials = 8
The expected value of a binomial distribution with probability of success P and number of trials n is defined by:
E(n, p) = n * p
Therefore, expected value when P = 0.5 and n = 8
E(8, 0.5) = 8 × 0.5
= 4
The expected value of the binomial distribution is 4
Answer:
