Answer:
Step-by-step explanation:
A = (3.14)(8)2
= 200.96
The amount A when the principal P is compounded continuously is given by the formula :

Here r is rate of interest and t is time .
In the question P=1600 ,r=6.5%=0.065 ,t= 6 years
Substituting these values in the formula

A= 1600(1.48)
A=2363.17
Balance after 6years is $2363.17
Notice that:

Now, we use the formula for the z-score:

Then the percentage of the calls that lasted less than 10 min is 15.87%
Answer:
12
Step-by-step explanation:
The expected value is
, where n=148 is the sample size and
.
We calculate the z-score of 37.5 using the formula:



From the standard normal distribution table, the area to the left of 1.43 is 0.9236.
.
The expected number of people in the sample with body temperatures above 37.5 degrees is 
We don't have a fractional human being, so the rule of thumb is to round up.
