Answer:
B. 2 3/5
Step-by-step explanation:
how i would solve this expression is start out by converting "4 1/3" into an improper fraction.
4 1/3 is equivalent to 13/3
next to find out how much water melissa used we have to multiply 3/5 by our improper fraction giving us this expression:
13/3 x 3/5
solving a fraction is simple, multiply the numerator by numerator,
and denominator by denominator.
so, we will end up with
39/15 or simplified to 2 3/5
hope this helps :D
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
