Answer: MAD= 3
Step-by-step explanation:
Find the mean of the data set
31+24+32+28+29+36/6= 30
subtract EACH data by the mean, find the absolute value of the answer
31-30= 1 (absolute value)
24-30= 6 (absolute value)
32-30= 2 (absolute value)
28-30= 2 (absolute value)
29-30= 1 (absolute value)
36-30= 6 (absolute value)
Now find the mean of the values
1+6+2+2+1+6/6=3
MAD=3
8.75 x 420.3 = 3677.625 m
3677.625/1125.803 = 3.266668 ft/sec
Answer:
an = 67 -11(n -1)
Step-by-step explanation:
The terms of your arithmetic sequence have a common difference of -11. The first term is 67.
These values can be used in the generic formula for the n-th term:
an = a1 +d(n -1) . . . . . . first term a1, common difference d
an = 67 -11(n -1) . . . . . formula for the n-th term
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
