Answer:
60 mph
Step-by-step explanation:
Time:miles
4:240
1:x
To get x divide 240 by 4 because that's what we divided 4 by to get 1
The rate is 60
select all times with the rate of 60 mph
Your answer should be -11.5
The correlation coefficient is a number that indicates the direction
and closeness of points of a line of best of fit.
So it tells us two things.
It tells us the direction of the line of best fit
and it tells us the closeness of the points.
Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.
It will be a negative correlation because the slope is negative.
Answer:
4
Step-by-step explanation:
rise/run = slope
As it goes to the left or adds by one, it goes up by 4
4/1

![\boxed{\boxed{\sf x=42\°}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B%5Csf%20x%3D42%5C%C2%B0%7D%7D)
Step-by-step explanation:
Given the diagram, we can see that ∠PQR and ∠RQS are complementary angles.
*Two angles with measures that add up to 90° are known as Complementary angles.*
Therefore, m∠PQR+m∠RQS=90°
![\sf \angle PQR+\angle RQS=90\°](https://tex.z-dn.net/?f=%5Csf%20%5Cangle%20PQR%2B%5Cangle%20RQS%3D90%5C%C2%B0)
![\sf 48+x=90\°](https://tex.z-dn.net/?f=%5Csf%2048%2Bx%3D90%5C%C2%B0)
Subtract 48 from both sides:
![\sf 48+x-48=90-48](https://tex.z-dn.net/?f=%5Csf%2048%2Bx-48%3D90-48)
![\sf x=42\°](https://tex.z-dn.net/?f=%5Csf%20x%3D42%5C%C2%B0)
