Orion is working with a data set that compares the outside temperature, in degrees celsius, to the number of gallons of ice cream sold per day at a local grocery store.
the data has a line of best fit modeled by the function f(x) = 3x + 4 . orion determines that when the temperature is 25∘c, the store should sell about 79 gallons of ice cream. the correlation coefficient of the data is 0.39.
explain how accurate orion expects the prediction to be.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

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)

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
