Hope it helps :)
Μ = 268 days, the population mean
σ = 9 days, the population standard deviation
For the random variable x = 272 days, the z-score is
z = (x-μ)/σ
= (272 - 268)/9
= 0.4444
From z-tables, obtain
P(z <= 0.6716) = 0.6716 = 67.2%
Answer: 67.2%

3+7=10
Answer:
4
Step-by-step explanation:
DA²= CB×CA
6²= y×(y+5)
36=y²+5y
y²+5y-36=0
x1+x2=-5
x1×x2=36
x1=4
x2=-9
x must be positive, then answer is 4
chek: 4×9=36
Answer:
