Answer:
There is a negative correlation in the data set.
Step-by-step explanation:
This can be found out by observing the fact that the points are decreasing as time goes on and the slope is downward from left to right.
In the given triangle , Coordinates of A (-1,3) , B (-5,-1), C (3,-1).
Let's find the slope of AB and AC .
Formula of slope is

For AB, slope is,

And slope of AC is

Product of the slopes of AB and AC is

Since the product of the two slopes is -1, so AB and AC are perpendicular.
And if they are perpendicular, angle BAC is 90 degree, so the triangle is right triangle .
Now we check the length of the sides of the triangle, and for that we use distance formula , which is

So for AB,

For AC,

For BC,

And since two sides are equal, so the triangle is isosceles triangle .
7x, 4y, 1are the terms, and 7x is the leading term.
Answer:
C. 8 miles per hour
Step-by-step explanation:
1/24th of an hour is 2.5 minutes, taking Diego 2.5 minutes to ride 1/3rd of a mile
2.5 x 3 (to signify how long it would take Diego to ride a mile) = 7.5 minutes
60 divided by 7.5 = 8
<em>Therefore, Diego's speed in MPH is </em><em>8.</em>
