If the problem is
(17 ^ 3) * (79 ^ 7)
The steps are:
Step 1:
(17 ^ 3) = 4913
Step 2:
(79 ^ 7) = 1.92039E + 13
Step 3:
(4913) * (1.92039E + 13) = 9.43488E + 16
If the problem is
(173) * (797)
Step 1:
Multiply both terms with a calculator:
(173) * (797) = 137881
Probability(not rain today) =100-15=85% ans is B
Answer:
D. Lines coincide
Step-by-step explanation:
On dividing y/2y and 4/8 and x/2x you get 1/2. Since 1/2 is common answer for all the parts, lines will coincide.
Answer:
The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

A confidence interval has two bounds, the lower and the upper
Lower bound:

Upper bound:

In this problem, we have that:

Lower bound:

Upper bound:

The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.
