Answer:
N = 9
M = 87.11
Step-by-step explanation:
According to the situation, the data provided and the solution are as follows
The scores for the student in the classroom is
= 88 88 92 88 88 72 96 88 84
The different student's number of scores is 9
The solution of new n and M is shown below:-
Sample size (n) = 9
Sample mean (m) is
= 
= 87.11
L (4, 6) M (-2, 1)
The width of the line is the difference in "X" values (4 minus -2 = 6) and the height is the difference in "Y" values (6 minus 1 =5)
So the midpoint of LM will be a point that is half-way of the "X" and "Y" distances (6/2 = 3 and 5/2 - 2.5)
"X" goes from -2 to 4. Adding 3 to -2 equals 1
"Y" goes from 1 to 6. Adding 2.5 to 1 equals 3.5
So the midpoint = (1, 3.5)
Answer:
15.09
Step-by-step explanation:
She ran only 12 times every 4 weeks, so we divide 60.36 by 4 which then becomes the result of running 3 days a week which means the answer is 15.09 because 15.09 multiplied by 4 is 60.36.
