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
Y - 3 = 1/2 (x + 4)
y - 3 = 1/2 x + 2
1/2x + 2 = y - 3
1/2x - y = -3 - 2
1/2x - y = -5 answer
