1. The scatterplot below shows the quarterback rating for 28 different NFL quarterbacks in the 2013 season, where x = QB rating after 4 weeks and y = QB rating at the end of the season. Quarterback rating
is complicated to calculate, but better performances result in bigger QB ratings. The line y = x and a
vertical line showing the mean QB rating after 4 weeks are also shown on the scatterplot.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
