yes it is because prime numbers are 2 ,3 , 5 ,7
Answer:
Leena walked 5/7 miles with her friend
Step-by-step explanation:
7/7 = 1
7 +4 =11
45 is your answer to 56-11
P = 0.11
1-p = .89
n = 200
mean = n*p = 22
std dev = n*sqrt(p(1-p)/n) = 4.425
find z values for standard normal distribution
Z= (30-22)/4.425 = 1/808
look up table to find P(Z less than 1.808) which is same P(x less than 30)
for 2nd part, you need 2 Z values
Z1 = (25-22) / 4.425 = 0.678
Z2 = (15-22) / 4.425 = -1.58
P(-1.58 less than Z less than 0.678) = P(Z less than .678) - P(Z less than - 1.58)
