Answer:
Yes
Step-by-step explanation:
9.8 - (-2.4) = 12.2
22 - 9.8 = 12.2
34.2 - 22 = 12.2
Since it increases by the same amount each time it is arithmetic

Answer:
7 is 50 , 8 is84, 9 is 45, 10 is 135, 11 is 155 and 12 is 80
Step-by-step explanation:
His average was 55.0 seconds, multiply that by the number of times he ran. This will give you the total time:
55.0 * 3 = 165 total seconds.
Subtract his times for the fastest and slowest to find the time for the third one:
165 - 54.3 - 56.1 = 54.6
The third race was 54.6 seconds.
Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2 ).
In this case:
J(-3,18)
T(7,-10)
The midpoint will be:
( (-3+7)/2 , (18-10)/2 )=(4/2 , 8/2)=(2, 4).
Answer: the midpoint of segment JT is (2,4)
