k=40
Step-by-step explanation:
subtract 12 from k we would get 28
Answer:
1139.82
Step-by-step explanation:
3.14×5.5×5.5×12= 1139.82
5.5×5.5=30.25
30.25×12=363.00
363×3.14=1139.82
Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
For this case we have:
The division given by:
102 ÷ 3 = 34
To verify its result we use multiplication as a reverse operation, that is:
We multiply the quotient by the divisor and its result must be the dividend.
So:

Multiplication,
