Answer:
r = 17 units
Step-by-step explanation:
The radius is the distance from the centre (- 7, - 1) to the point on the circle
(8, 7)
Use the distance formula to calculate the radius (r)
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)
r =
=
= = 17 units
52 miles per hour.
Divide 234 by 4.5, as that is what you must divide 4.5 by to get 1.
234/4.5 = 52 miles per hour.
The median is 120.
The lower quartile is 112.
The upper quartile is 140.
The interquartile range is 28.
Hope this helps <333
It would be 150+300 which equals 450.
