The average is pretty simple to find. Add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
The answer to this specific question can be modeled as 
. After simplifying everything, you would get x 
77, so Justin has to get at least a 77 to get a 75 average.
I am pretty sure the answer is c
m = 16
8 6
Cross multiply:
m * 6 = 8 * 16
Simplifying
m * 6 = 8 * 16
Reorder the terms for easier multiplication:
6m = 8 * 16
Multiply 8 * 16
6m = 128
Solving
6m = 128
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Divide each side by '6'.
m = 21.33333333
Simplifying
m = 21.33333333
Answer:
is there a picture that u could send
Answer: 9.9 years.
Step-by-step explanation:
If interest is compounded continuously, then formula to compute final amount A = 
, where P =initial amount, r= rate of interest , t=time.
Given: P= $61,000, r= 1.9% =0.019 , A = $ 73600
Substitute all values in formula
Taking natural log on both sides
Hence, the required time = 9.9 years.
