Answer:
answer : B
Step-by-step explanation:
( x + 7) (3x -2) = 3x² - 2x +21x -14
( x + 7) (3x -2) = 3x²+19x -14
The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.
<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.
59.32 - 59.1 = 0.22
2.4 - 1.5 = 0.9
0.22 / 0.9 = 0.25
Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

Answer:
8
Step-by-step explanation:
45 divided by 5 is 9 and what you do on the to you do on the bottom which means you would do 40 divided by 5 which you would get 8 as your answer.
They could be 28 + 29 + 30
1km=1000metres
15km=15000 metres
15000/600=25
25-1=24 (minus the last one)
hope this helps :)
