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 sum of all observations divided by the number of observations.

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%.

Vera_Pavlovna [14]

Answer:

Jack's final bank account amount will be $54,782.50, earning $7,459.31 in interest.

General Formulas and Concepts:
Algebra I

Compounded Interest Rate Formula: $\displaystyle A = P \bigg( 1 + \frac{r}{n} \bigg) ^{nt}$

A is final amount
P is principle amount
r is rate
n is compounded rate
t is time

Step-by-step explanation:

Step 1: Define

Identify given variables.

P = $47,323.15

r = 0.05

n = 1

t = 3

Step 2: Find Interest

[Compounded Interest Rate Formula] Substitute in variables:
$\displaystyle A = 47323.15 \bigg( 1 + \frac{0.05}{1} \bigg) ^{1(3)}$
Evaluate:
$\displaystyle A = \boxed{54782.5}$
