No because in a square a area is base times height and the sides are equal so you don't have to subtract but the answer 64 can be the area of a square of the square sides are 8

Calculate the equation of the line if two points are (1,6) and (5,0) Hint, you will have to find the slope of the line and then

Answer:

The equation is $y=\frac{-3}{2} x-9$

Step-by-step explanation:

First, you will have to find the slope of the two points.To do that, you will have to use the formula : $m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

Our points are $(1,6)$ and $(5,0)$

We will have to substitute the points into the formula.

$m=\frac{0-6}{5-1}$

Then, we will simplify

$m= \frac{-6}{4}$

We could simplify that fraction into $\frac{-3}{2}$

So, our slope is $\frac{-3}{2}$

We will have to pick a coordinate point, and choose. I chose $(1,6)$

We will substitute the x-value and the y-value of the coordinate point, including our slope, to calculate the y-intercept.

The formula we will be using is $y=mx+b$

We will substitute in our values which will make it look like:

$6=\frac{-3}{2} (1)+b$

We will then multiply $\frac{-3}{2}$ by $1$ which will stay the same.

Then, we will multiply $\frac{-3}{2}$ by $6$ which will equal $-9$

$-9=b$

Hence, the equation for our line is $y=\frac{-3}{2} x-9$

Hope it helped:D

Since the range of the scores given was between 300 and 700 (which is 2 standard deviations below and above the mean), the probability that a randomly selected student's math score - as based on the empirical rule of statistics - is 95%. In decimal form, it is .95.
