Answer:

I am assuming you are asking for what percent correct she got. She got 46% correct.

Step-by-step explanation:

You divide the answers correct by the total questions. She got 69 out of 150, so dividing that is .46

To turn a decimal into a percentage, just move the decimal two places to the right, thus getting 46 %

If I assumed what you were asking incorrectly, let me know and I'll be happy to help!

In these kind of problems, it's always the best to just draw it. There are "formulas" to calculate this, but it's better to know intuitively.

Midpoint, as the name suggests is the point that is exactly halfway between two points. To find a midpoint in one dimension, we would take an average between those two points.
Example: Number exactly halfway between 8 and 16 is $\frac{8 + 16}{2}= 12$

We can do the same for two dimensions, it just means we'll have to calculate both for x-values and y-values

Midpoint $( \frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} ) = ( \frac{9-1 }{2} , \frac{8-2 }{2} ) =( 4, 3 )$

Using the identity (a+b)(a+b) = a^2 + 2ab + b^2 we get the answer 4Z^2 + 20Z + 25
