Answer:
Option D
Step-by-step explanation:
A reporter collects a random sample of 50 runners from all the runners who finished the Cherry Blossom Ten Mile Run in 2009 and constructs a 99% confidence interval for the true mean finish time to be (86.05, 99.38) minutes.
Assuming the reporter performed the calculations correctly, which of the following statements are appropriate interpretations of this confidence interval?
We can expect that 99% of confidence intervals created using the same method the reporter used will contain the true mean run time for runners of this race.

Answer: the area of the finished tarp is 131872 square inches
Step-by-step explanation:
Search strip of tarp is rectangular. The formula for determining the area of a rectangle is expressed as
Area = length × width
An order was placed for a rectangular tarp that will be made up of 8 strips of fabric. Each strip is 26 inches wide and 634 feet long. The area of each strip of tarp is
Area = 26 × 634 = 16484 square inches
Therefore, the area of the finished tarp would be
8 × 16484 = 131872 square inches
