What does a regression line really tell us? There are actually four things it can tell us, but I only need you and your group to

come up with two things (try for four, though!). As a hint, see if you can address these issues: what does it do, what can we use it for, how does it differentiate values, what can it tell us about the data?

Answer:

Here is one idea:

You can use a regression line to predict what will happen at a time not given by your data.  You can use it to make predictions about future times.

Here is another one:

The equation for the regression line or even the graph of can tell us if the data is increasing as we move through future times or if it is decreasing as we move through future times.

Try to come up with one of your own so you can have three. :)

Ahat [919]

Answer:

The length of mid-segment XY=4 units

Step-by-step explanation:

Given:

Length of QR=8 units

XY is the mid-segment which means the line joining the midpoints of two sides of triangle.

By mid-segment theorem the mid-segment of a triangle is parallel to the third side and half of the length of third side.

So, we can write:

XY=\frac{1}{2}QR  

XY=\frac{1}{2}(8)

∴ XY=4 units

∴The length of mid-segment XY=4 units

Find the area of the semi circle
Aleonysh [2.5K]

Answer:

76.96902001

Step-by-step explanation:

We know that the area of a circle is pi * r^2 so we can take that equation and divide it by two to get your answer. So in this case it would be \frac{pi*7*2}{2}. Hope this helps!
