Answer 1

88

Explanation:

Answer 2

The average in Algebra I is 88.

Given:

79, 84, 84, 90, 91, 100

Solution:

The average is find the arithmetic mean of the given data.

The average is found by total all the data divided by number of data.

Let us assume, each scores with a variable for better understanding.

`A=79`

`B=84`

`C=84`

`D=90`

`E=91`

`F=100`

Let's take the average as 'A'.

The average of the given scores in formula is:

`A=(A+B+C+D+E+F)/(6)`

On substituting the values,

`\Rightarrow A=(79+84+84+90+91+100)/(6)`

`\Rightarrow A=(528)/(6)`

Now,

`\therefore A=88`
