Answer:
After n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Step-by-step explanation:
Given;
estimated annual sales, a = 9600 units
determine common ratio, r;

sum of the units in use after n years is calculated by applying sum of nth term;


Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.
Answer:
Step-by-step explanation:
Mean is just another word for average. To find the average, add up all the values then divide by the number of values.
There are 7 values in the first data set. The average is:
(3 + 4 + 6 + 4 + 3 + 1 + 4) / 7 = 25/7 ≈ 3.57
There are 7 values in the second data set. The average is:
(6 + 7 + 2 + 4 + 5 + 5 + 3) / 7 = 32/7 ≈ 4.57
I solved the problem, answer is 11.4% as 2500-11.4% is 2215.

There are
shaded parts and
total parts.
Write this as a fraction.

Simplify the fraction.
