Answer:
3.5cm
Step-by-step explanation:
Vol=πr²h
Transposing for h,=vol÷πr²
where r=22/2=11cm and taking π=3.142
h=1331/(3.142×(11)²)=3.5cm
Answer:
16.4
Step-by-step explanation:
If it is asking for the tenth it will be the 1st one after the point and you round it to the next one.

Answer:
A Poisson distribution, with λ=5.3
Step-by-step explanation:
For this type of random variables, a Poisson distribution is the most adecuate.
If the number of occurrences in ten minutes is 5.3, we can define the parameter λ=5.3 and the probability function as:
Answer:
B
Step-by-step explanation:
n - 4 = 4.5 - 4 = 0.5
8(n - 4) = 8 *(0.5 ) = 4
6 *n = 6 * 4.5 = 27
8(n - 4) + 6n
8(0.5) + 6*4.5
4 + 27
