Answer: Andrew - 1.875 Michael- 3.125
Step-by-step explanation:
If Andrew overtakes in 8 hours, we can divide 15 miles by 8 to see how many miles per hour he goes.
15/8 = 1.875
Then we can multiply 1.875 by 3 to see how much he traveled while walking towards Michael.
1.875*3=5.265- the distance he traveled
Now subtract that by 15 to see how many miles Michael walked.
15-5.625=9.375
That means Michael walked 9.375 miles.
Divide 9.375 by 3 to see how many miles he walked per hour
9.375/ 3 = 3.125
The mean absolute deviation is the average distance between each number, and the mean, so the answer is 2.4 Hope this helps.
Answer:

Step-by-step explanation:
the pattern is *2 then -2
3*2=6
6-2=4
4*2=8
8-2=6
6*2=12
<h2>12-2=
10</h2>
Answer:
8748
Step-by-step explanation:
The formula for the nth term in a geometric sequence is ar^n-1.
We can find the first term, as a(3)^4-1 = 108 which also means that 27a = 108.
a = 4.
We find the 8th term using this:
(4)(3)^8-1 = (4)(3)^7 = 8748.
