Answer: 75
Step-by-step explanation:
Multiple all those numbers together and then divide by 3
Answer:
3 tan theta=root 3
tan theta=root 3/3
tan theta=0.57
Step-by-step explanation:
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.
