Hope this helps, thank you :) !!
This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero.
To do this, we will multiply -3 to (x=3y=31)
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73
Answer:
60 70 80m9
Step-by-step explanation:
Let the mean number of cars passing through intersection 1 be μ1 and that of intersection 2 be μ2. Then the appropriate test of the city planner's hypothesis is
H0: μ1 - μ2 = 0
H1: μ1 - μ2 ≠ 0
