Step-by-step explanation:
The answer is provided in the options. The answer should have been A, if the question was 3x²-27.
Answer:
2x + 3y = 13
4x - y = -2
In the second equation, subtract 4x from both sides.
-y = -2 - 4x
Divide both sides by -1.
y = 2 + 4x
Put this into the first equation in place of y.
2x + 3(2 + 4x) = 13
Multiply everything in the parenthesis by 3.
2x + 6 + 12x = 13
Combine like terms.
14x + 6 = 13
Subtract 6 from both sides.
14x = 7
Divide 14 on both sides.
x = 7 / 14
x = 0.5
Put this into the second equation in place of x.
4(0.5) - y = -2
2 - y = -2
Subtract 2 from both sides.
-y = -4
Divide both sides by -1.
y = 4
So x = 0.5 and y = 4.

Answer:
The degrees of freedom associated with this problem are 16.
Step-by-step explanation:
The degrees of freedom associated with a problem, independent of the confidence level, is the sample size subtracted by 1.
In this problem, we have that:
She takes a random sample of 17 trucks, so the sample size is 17.
This means that the degrees of freedom associated with this problem are 16.
