7 students......receive 0
5 students......receive 3......thats $ 15
7 students.....receive 5.......thats $ 35
3 students.....receive 6.......thats $ 18
2 students.....receive 8.......thats $ 16
the mean (or the average) can be found by adding up the total amount received and dividing by how many students there were.
so the mean is : (0 + 15 + 35 + 18 + 16) / (7 + 5 + 7 + 3 + 2) =
84 / 24 = 3.5 <==
Y=(6/7)x - 1/2 (where 1/2 is the y intercept and 6/7 is the slope)
Line
for me convert to slope intercept form
y=mx+b
m=slope
b=y intercept, aka whre the line crosses the y axis
y-2=4(x-5)
y-2=4x-20
y=4x-18
slope=4
yint=-18
positive slope so it goes from bottom left to top right
crosses y axis at -18
first 2 don' cross at -18
3rd, dunno
4th, is going from top left to bottom right, incorrect
answer is 3rd one
