The answer will be the last one as it equals 4x + 3. this means that the equation will be parallel and does not have a solution.
A) the z score for 95% is 1.96
Multiply by the deviation:
1.96 x 0.005 = 0.0098
Now add and then subtract that from the mean:
4.035 - 0.0098 = 4.0252
4.035 + 0.0098 = 4.0448
The interval is (4.0252, 4.0448)
B) 4.035 +/- 1.96 x sqrt( 0.005/sqrt(25))
= 4.035 +/-0.00196
Answer: ( 4.033, 4.037)
C) the conclusion is that both 4.020 and 4.055 are out of the range.
4.020 is below the lowest range and 5.055 is higher than highest range.

....
3x-2y= -12
y=4x+1
3x-2(4x+1)= -12
3x-8x-2= -12
-5x=-12+2
-5x=-10
x= -10/-5
x=2
y=4x+1
y=4•2+1
y=8+1
y=9
(x,y) = (2,9)
