Using that equation, our P = 150, r = .08, t = 13, and n = 12 (because there are 12 months in a year). Filling in accordingly, we have
. Simplifying a bit we have
. Doing the addition inside the parenthesis and then raising that number to the 156th power, we have
. Multiply those and get A(t) = $422.92
Answer:
1.39
Step-by-step explanation:
100 = 12x, this finds how many hours she works total over 6 days.
so x = 8.33, so she works 8.33 hours per 6 days.
8.33 = 6x, solves for how many hours per day
x = 1.38
So she works 1.38 hours everyday.

Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.
The mean of a data-set is the <u>sum of all observations divided by the number of observations</u>.
In this problem:
- In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is
. - In the next n observations, mean of 1.
Hence, the mean is:
We want the mean to be of 0.9, thus:
3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.
