The list shows the yards gained and lost during the first several lays of a football game: 8,4,3,7,-15,20,5,-12,32,1
how can i write an expression that shows how to compute the average of gain or loss per play. then compute the average

Solve for mean, +5.3 yards per play on average

Step-by-step explanation:

Add all the numbers together, which gives 53 yards. Now, divide by the number of plays.

53/10=5.3 yards per play increase on average

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
