Answer:

10.-8/-2 can't represent calculating a mean change in score because a mean change in score is counted by adding up the scores & then dividing it by the number of the scores. As a number of scores can never be negative, so -8 can't be divided by -2 . So, -8/-2 can't represent this.

6. a) Andrea's mean weekly change will be negative. Because after adding up her weekly changes, we'll find a negative number. & as the number of weeks is positive, then the mean will be a negative number .

b)the division equation is: -15/5

So, her mean weekly change is -3

Answer:

9 1/3

Step-by-step explanation:

As you may know, when you divide a positive number by a negative number, the quotient (result of the division) is negative.

Knowing this, all you have to do is divide the numbers normally as positive numbers and then add a negative sign at the end.

To divide fractions, you change the sign to multiplication and multiply the first number by the reciprocal of the second number.

The reciprocal is just the "flipped" version of a fraction.

For example, the reciprocal of 3/4 would be 4/3.

In this problem, you can't reduce.

So, just multiply the top numbers and do the same with the bottom numbers.

That would be \frac{35*4}{5*3}.

35*4=140 and 5*3=15.

The fraction would be 140/15

You can divide 140 by 15, which would be 9 and 1/3
