The scatter plot shows the time spent studying ,x, and the midterm score, y, for each of 25 students. Use the equation of the line of best fit, y=3.85x+15.60, to answer the questions below. Give exact answers, not rounded approximations. (A) What is the predicted midterm score for a student who doesn't spend any time studying? (B) What is the predicted midterm score for a student who studies for 15 hours? (C) For an increase of one hour in the time spent studying, what is the predicted increase in the midterm score?

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

answer: i wpould go with c

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
