Answer:
0.708
Step-by-step explanation:
The calculation of the value of the linear correlation coefficient R is shown below:-
Cost Number
9 85
2 52
3 55
4 68
2 67
5 86
9 83
10 73
Value of linear correlation coefficient R is 0.70772136
or
= 0.708
For clarification look at the spreadsheet which has been attached and uses the following steps which are as follows
Step 1
To activate the data analysis option:- Go to file menu click on add-in option and choose the manage option and select Excel Add-in option click on Ok after that choose Analysis Tool Pak
Step 2
After following step 1 choose data tab and select data analysis tab and select correlation and click ok
Step 3
After selecting correlation to select the range from $A$2:$B$9 and then click OK to reach the value of linear correlation coefficient R.
The most reasonable answer is D.
8.8 will round to 9 and 2.7 will round to 3, and the division will round to 3. Bruce's answer rounds to 4, so his answer is not reasonable.

<u>Answer</u>:
Angle A = 17°, Angle B = 73°
<u>Step-by-step explanation:</u>
Angle A & Angle B are complementary angles (given) so they will form 90°.
Let's take,
Angle A = x
Angle B = 4x +5 (angle B is five degrees more than four times angle A)
Measure of each angle=?
Angle A + Angle B = 90°
x + 4x + 5 = 90
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85 ÷ 5
x = <u>1</u><u>7</u><u>°</u>
Angle A = x = <u>1</u><u>7</u><u>°</u>
Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = <u>7</u><u>3</u><u>°</u>
