Which phrase best describes the regression model for the data? Review the table of values showing the number of days each year from 1990 to 1997 that air quality in San Diego did not meet federal air quality standards.

>>Which phrase best describes the regression model for the data?<<

A) power model; y = 41.21x–0.86

B) exponential model; y = 54.97(0.71)x

C) logarithmic model; y = 39.14 – 17.93 ln x

D) quadratic model; y = 0.60x2 – 10.38x + 46.73

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

the correct answer is 5 6 and 7

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
