Answer:
The answer is 440 in2 because the rest of the answers are incorrect.
Step-by-step explanation:
The correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.
<h3>What is mean?</h3>
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The difference between the mean times is about 16 times the mean absolute deviation of the data set.
127.9-127.4=0.5
0.26-0.23=0.03
0.5/0.03=16.6666
We can see that the ratio of the mean times difference is 16 times the mean deviation by solving the above.
Therefore the correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.

Answer:
B
Step-by-step explanation:
cos B = = = =
-2 ( 27) =( - 12) 3/ 8
- 54 = 4.5
Not sure how to do it in this form but in slope intercept form for example if the slope was -4/3 the perpendicular would be 3/4 it’s the negative reciprocal of the answer
