At track practice trina and 8.5 miles in 41 minutes and 22 seconds on average how long did it take trina to run each mile

(x,y)→(-y,x).

Then

R(−4, −1)→R''(1,-4);

S(−1, −1)→S''(1,-1);

T(−4, −2)→T''(2,-4).

2. Translation 2 units up has a rule:

(x,y)→(x,y+2).

Then:

R''(1,-4)→R'(1,-2);

S''(1,-1)→S'(1,1);

T′'(2,-4)→T'(2,-2).

1st transforamation - option D, 2nd transformation

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

sorry can't

i googled though and something came up but it was in science langueage not common english sooo
