Answer:
Step-by-step explanation:
Give the rate of change of sales revenue of a store modeled by the equation 
. The Total sales revenue function S(t) can be gotten by integrating the function given as shown;
a) The total sales for the first week after the campaign ends (t = 0 to t = 7) is expressed as shown;
Total sales = S(7) - S(0)
= 6,860 - 0
Total sales for the first week = $6,860
b) The total sales for the secondweek after the campaign ends (t = 7 to t = 14) is expressed as shown;
Total sales for the second week = S(14)-S(7)
Given S(7) = 6,860
To get S(14);
The total sales for the second week after campaign ends = 13,720 - 6,860
= $6,860
function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation.
The answer is C, 6 x 4 = 24!
Answer:
The monthly payments = $ 297
Step-by-step explanation:
It is given that,Tom’s total payment for his loan was $14,256 he paid it off at making 48 monthly payments
<u>To find the monthly payments</u>
we have,
Total payment = $14256
Number of monthly payments = 48
Monthly payments = 14256/48 = 297
Therefore Tom's monthly payments of his loan = $ 297
Answer:
a. With 90% confidence the proportion of all Americans who favor the new Green initiative is between 0.6290 and 0.6948.
b. If the sample size is changed, the confidence interval changes as the standard error depends on sample size.
About 90% percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about 10% percent will not contain the true population proportion.
Step-by-step explanation:
We have to calculate a 90% confidence interval for the proportion.
The sample proportion is p=0.6619.
The standard error of the proportion is:
The critical z-value for a 90% confidence interval is z=1.6449.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 90% confidence interval for the population proportion is (0.6290, 0.6948).
