Based upon data from his AP United States History class, Mr. Unsworth determined that the relationship between a student's hours watching TV per week (x) and that student's score on the AP
(y) exam were negatively correlated. He determined that the equation of the best fit line is
y = -0.21x + 5.22. Based upon these results, predict a student's AP score (to the nearest whole
number) if he watches 12 hours of TV a week.

95.03 is the answer. hope this !

sorry man i accidentally pressed yes my bad

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
