WEATHER The daily high temperature (in oF) in a city for the first 10 days of last year were: 38, 48, 51, 53, 64, 69, 51, 53, 43 and 36. For the first 10 days of this year, they were: 32, 17, 30, 34, 35, 40, 43, 36, 38
and 28. Compare the standard deviations for the two years

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
