Having done poorly on their math final exams in​ June, six students repeat the course in summer​ school, then take another exam in August. If we consider these students representative of all students who might attend this summer school in other​ years. Do these results provide evidence that the program is worthwhile? June 54, 49, 68, 66, 62, 62

August 50, 65, 74, 64, 68, 72

Required:

Evaluate on a TI 83 calculator

23

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
