The standard error of the mean is 128.125.
The formula for standard error is:

With our information, we have:
It is a supplementary angle. D because the add up to 180.
Answer:
No
Step-by-step explanation:
Answer:
the slope is 6/7 the y-intercept is (0, -
)
Step-by-step explanation:
I'm not 100% sure sorry lol.
Y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m
so
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
points (-2,3) and (3,0)
slope is (0-3)/(3-(-2))=-3/(3+2)=-3/5
a point is (3,0) Or (-2,3)
so it could be
y-0=-3/5(x-3) or y-3=-3/5(x-(-2)) which is equal to y-3=-3/5(x+2)
that's the answer
B is answer
