fredd [130]

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

on the last 5 quizzes, marco has earned a total of 21 out of 25 possible points. if he has a perfect score on the next several q
nevsk [136]

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 \frac{21}{25} = 0.84.
  • In the next n observations, mean of 1.

Hence, the mean is:

M = \frac{0.84(5) + n}{5 + n} = \frac{4.2 + n}{5 + n}

We want the mean to be of 0.9, thus:

M = 0.9

\frac{4.2 + n}{5 + n} = 0.9

4.2 + n = 0.9n + 4.5

0.1n = 0.3

n = \frac{0.3}{0.1}

n = 3

3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.
