Answer:
The sample size needed is 2401.
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 of the interval is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use 






The sample size needed is 2401.

Fido's dog must lose 1.17 pounds each month to reach healthier weight.
Step-by-step explanation:
Given,
Weight of fido's dog = 35 pounds
Time period = 6 months
Goal weight to reach = 28 or less pounds
Let,
m be the weight to be lose each month.
Weight of dog - Time period * Weight to lose each month ≤ Goal weight

Dividing both sides by -6

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

Answer:
The total profit P(x) or the month is
.
Step-by-step explanation:
A company produces x units of a product per month.
The total cost represents by the function C(x).

The total revenue represents by the function R(x).

The profit is the difference between revenue and cost.



Combine like terms.


Therefore, the total profit P(x) or the month is
.
