At most 12 peppers can be bought with $18
Step-by-step explanation:
Given
Total amount for peppers = $18
Cost per pepper = $1.50
Let p be the number of peppers that can be bought from $18 at $1.50 per pepper
So,
Dividing both sides by 1.50
Hence,

Answer:
The 98% confidence interval for the mean repair cost for the dryers is (83.4161, 103.3039).
Step-by-step explanation:
We have a small sample size n = 25, and s = 19.95. The confidence interval is given by
where
is the
th quantile of the t distribution with n - 1 = 25 - 1 = 24 degrees of freedom. As we want the 98% confidence interval, we have that
and the confidence interval is
where
is the 1st quantile of the t distribution with 24 df, i.e.,
. Then, we have
and the 98% confidence interval is given by (83.4161, 103.3039).
bear in mind that the degree of a polynomial comes from the highest degree of any of its terms, and the degree of a term is the sum of all exponents in the variables.
