Mifrin, the manufacturer of an over-the-counter pain reliever, claims that its product brings relief to headache sufferers in less than 3.5 minutes, on average. To make this claim in its commercials, Mifrin was required to show evidence that headache relief really did come in less than 3.5 minutes, on average. Mifrin reported that for a random sample of 50 headache sufferers, the mean time to relief was 3.3 minutes and the standard deviation was 60 seconds. You would like to estimate the average time it takes for headache sufferers to feel relief after taking Mifrin. Which of the following would you use to calculate the 99% confidence interval? a. z = ±2.300
b. z = ±2.575
c. t = ±2.678
d. t = ±2.403

i think asking google will you get the answer to that question

answer: 3.26019516

step-by-step explanation:

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
