I would say sometimes since JK and JL both start with the letter "J" meaning that the endpoint in called "J." There are infinite other points along that ray that can be named anything so that means "JK" and "JL" are possible.
Find the mean, median mode and range of: 75, 80, 60, 90, 85, 80, -7, 90, 70, 65

Answer:
Mean: 68.8.
Median: 77.5
Mode: 80, 90
Step-by-step explanation:
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90
(75, 80) are the middle numbers, so add them both, then divide by 2.
80, 90 appear more than the other numbers.
Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.
. Distance = Speed * Time
Let s represent the speed of the cars in miles per hour. The problem statement tells you
.. red car distance + 25 miles = blue car distance
.. s*3 + 25 = s*(3 + 0.5)
.. 25 = 0.5s ... subtract 3s from both sides
.. 50 = s ... multiply by 2
The speed of the red and blue cars is 50 miles per hour.
True. Force is equal to mass times acceleration. So if we have a mass of 5kg and an acceleration of 3. Then the force is 15 N
