3 minutes because 60 minutes = an hour so 60/20 = 3 minutes so 3 minutes per mile
Answer:
C or d
Step-by-step explanation:
Answer:
mean = 2.55
Standard deviation = 1.118
Step-by-step explanation:
Probability of babies who are boys
P = 0.51
Then we have q = 1-p
= 1-0.51
= 0.49
We have n = 5
We calculate the mean as:
np
= 0.51x5
= 2.55
Therefore mean = 2.55
The standard deviation
= √variance
= √npq
= √0.51x5x0.49
=√1.2495
= 1.118
20 because it is counting by fives (5,10,15,20) and 5x4=20
