A.= 9/8 OR 1 1/8
B.= 11/12
C.= 17/12 OR 1 5/8
Answer:
n > -4/3
Step by step
Step by step solution :
Step 1 :
Equation at the end of step 1 :
25 - (0 - 3 • (4n - 3)) > 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
12n + 16 = 4 • (3n + 4)
Equation at the end of step 3 :
4 • (3n + 4) > 0
Step 4 :
4.1 Divide both sides by 4
4.2 Divide both sides by 3
n+(4/3) > 0
Solve Basic Inequality :
4.3 Subtract 4/3 from both sides
n > -4/3
Answer:
the business is a goo
Step-by-step explanation:
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%.
