Answer 1

Answer:

75.7 I think that is the answer

Answer 2

Answer:

Final answer:

To find the mean absolute deviation, calculate the absolute difference between each value and the mean, then find the average of those absolute differences.

Explanation:

To find the mean absolute deviation for the given set, follow these steps:

Calculate the mean of the set by adding up all the values and dividing by the total count.
Find the absolute difference between each value and the mean.
Add up all the absolute differences.
Divide the sum of absolute differences by the total count.

In this case, the mean of the set is (65+90+85+70+70+95+55)/7 = 74.29

The absolute differences between each value and the mean are: |65-74.29|, |90-74.29|, |85-74.29|, |70-74.29|, |70-74.29|, |95-74.29|, |55-74.29| which simplify to 9.29, 15.71, 10.71, 4.29, 4.29, 20.71, 19.29

The sum of the absolute differences is 84.29

Finally, divide the sum by the total count: 84.29/7 = 12.04

So, the mean absolute deviation for the given set is approximately 12.04

A striped marlin can swim at a rate of 70 miles per hour. Is this a faster or slower rate than a sailfish, which takes 30 minutes to swim 40 miles? Show your work.

Answers

Let's do the work shall we....

this is going to be a ratio problem.

Striped Marlin:
70 miles/ One hour (Or 60 minutes)

Sailfish:
40 miles/ 30 minutes.

Since 30 minutes is only one half of 60 minutes, all we have to do is multiply the sailfish ratio by 2 in order to receive the correct mph.

(40miles/30 minutes) x2 = (80 miles/60 minutes(or one hour)).

Therefore, the sailfish is faster! 80 miles per hour is faster than the 70 mph marlin.

You convert the minutes to hours and the marlin is slower because 70 mph is less than 80 mph.My work is in the attachment.

What is the mean of 87, 93, 86, 90, and 84?

Answers

88 would be the mean.

Final answer:

The mean of 87, 93, 86, 90, and 84 is 88.

Explanation:

To find the mean of a set of numbers, you need to sum up all the numbers in the set and then divide by the total number of values. For this set, the sum is 87 + 93 + 86 + 90 + 84 = 440. There are 5 numbers in the set, so to find the mean, you divide the sum by 5: 440 ÷ 5 = 88.
