Answer:

$\boxed {\tt 90 \%}$

Step-by-step explanation:

The average can be found by adding up all the values and dividing by the number of values.

1. Add the values

The values are her five test scores: 100, 95, 75, 100, 80

Add them : 100+ 95+75+100+80 = 450

2. Divide by the number of values

She took five tests, so there are five values. Divide 450 by 5.

450/5=90 = 90%

Her average grade is 90%

How do I convert a fraction to decimals

Andre45 [30]

Every fraction is a short way to write a division problem.
A fraction means

(the top number) divided by (the bottom number).

When you go ahead and actually do the division, the quotient you get
is the decimal form of the fraction.

Example:

Let's say you have the fraction 792 / 3168 .

Just pull out your pencil or your calculator, and divide 792 by 3168.

You'll get 0.25 . That's the decimal form of that whole ugly fraction !

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What

Answer:

0.98

Step-by-step explanation:

The investment starts at $10,000.

$10,000 is 100% of the investment.

In the first year, it loses 2% of its value. That means that after 1 year, the value of 100% of $10,000 is decreased by 2% of $10,000.

100% - 2% = 98%
