Ok so
basically solve for y
2x+18y=36
subtract 2x from both sides
18y=-2x+36
divide both sides b 18
y=-1/9x+2
Answer:
The requirements for the hypothesis test are not met
Step-by-step explanation:
We have the following information from the statement:
sample size = n = 60
Probability = p = 13% = 0.13
Now, we calculate the multiplication of this which would be:
n * p = 60 * (0.13) = 7.8 which is less than 10
Therefore the requirements for the hypothesis test are not met, since the multiplication of n by p would have to be greater than 10 for it to be met, but this is not the case.
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
