You used the fact that you can multiply both sides of an equality by the same, non-zero constant.
So, if you start with the trivial equality
you can multiply both sides by 3:
But if 
, 
becomes 
, which is 
. So, we have
which leads to
if you recall that
Answer:
Its D
Step-by-step explanation:
Slope intercept form is y=MX +B
if you plug it in, it would be y=1/8x+3 meaning 1/8 is the slope (m) and 3 is the y intercept (b)

40x is the number of lawns he can do, less the time to do his grandparents time (added to other law time) and he has 660 mins of less to complete them.
<span>(1) What are the values of the sample proportion of people who live within 1 mile of a hazardous waste site and its standard error?
Solution:
pˆ = 0.3, and standard error p
0.3 Ă— 0.7/450 = 0.0216.
(2) What are the values of the sample proportion of people who live outside of the 1 mile radius around a hazardous waste site and its standard error?
Solution:
pˆ = 0.7, and standard error p
0.3 Ă— 0.7/450 = 0.0216.</span>
