Answer:
her total profit is 3
Step-by-step explanation:
1.50 x 30 = 45
to find total profit - 45-42= 3
Multiply all of the numbers together: 5 x 2 x 8 = 10 x 8 = 80 ways
To answer this question with the choices given, you would substitute the possible answers into your work for the base and the height of each dimension on the entire campground.
To find the length of the campground, you multiply each choice by 5 because there are 5 campsites.
For the width, you add each choice to 4.
Then you multiply the total length by the total width to see if your answer is 950 square yards.
See the attached picture for all the work.
Answer:
The 99% confidence interval = (126.93,157.67)
Step-by-step explanation:
The formula for Confidence Interval =
Mean ± z × Standard deviation /√n
Mean = 142. 3 mmHg
Standard deviation = 20.8 mmHg.
n = 12
Z score for 99% confidence interval = 2.56
Confidence Interval =
142.3 ± 2.56 × 20.8/√12
142.3 ± 2.56 × 6.0044427996
142.3 ± 15.371373567
Confidence Interval
= 142.3 - 15.371373567
= 126.92862643
≈ 126.93
142.3 + 15.371373567
= 157.67137357
≈ 157.67
Therefore, the 99% confidence interval = (126.93,157.67)
