Step-by-step explanation:
Answer:
8%
Step-by-step explanation:
1) create equation
y = (4)2.5 + 125
2) simplify
y = 10 + 125
y = 135
3) find difference
x = 135-125/125
x = 0.08
x = 8%
Answer:
its d
Step-by-step explanation:
i just took it
If a variable is binomially distributed with n trials and a success probability of p, then the mean = np, variance = np(1–p) and standard deviation = square root of variance.
In this case, n = 1200, p = 0.35. So, mean = (1200)(0.35) = 420,
variance = (1200)(0.35)(1–0.35) = 273,
standard deviation = square root of variance = √273 = 16.52.
