B.0.15
Step-by-step explanation:
To approximate a binomial distribution as a normal distribution, two conditions must be met:
np > 10
nq = n (1−p) > 10
Here, n = 250. Check each value of p to see if it meets the conditions.
A. p = 0.03
np = 7.5, nq = 242.5
B. p = 0.15
np = 37.5, nq = 212.5
C. p = 0.02
np = 5, nq = 245
D. p = 0.97
np = 242.5, nq = 7.5
E. p = 0.99
np = 247.5, nq = 2.5
Of the five choices, only B meets both conditions.

1. Answer is 4.5 km / hr.
... because you divide the time but the distance so for this question you divide 22.5 by 5 and that's your answer. do the same for every question! hope this helps.
