The help desk is keeping track of the number of minutes the average caller spends on hold. A 2-column table with 6 rows titled Average Time on Hold with Help Desk. The first column is labeled Week with entries 1, 2, 3, 4, 5, 6. The second column is labeled Average Time on Hold (minutes) with entries 7, 5, 3, 2, 3, 5.
According to the table, during which interval did the average time spent on hold increase?

week 1 to week 3
week 1 to week 4
week 4 to week 6
week 3 to week 5

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

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)
