Answer:
allow more accurate modeling
Step-by-step explanation:
They ask us what we should expect from a normally distributed error term with of zero, we analyze each option:
a. have values that are symmetric about the variance.
False, does not guarantee symmetry.
b. allow more accurate modeling.
It is correct, in this case we would have a more accurate model.
c. yield biased regression estimates.
it is also false, not necessarily.
d. be a hyperbolic curve.
false, not necessarily.
The system of equation that has one solution is: (d) –2x+ 7y = –5 and 2x +7y = –9
<h3>What are systems of equations?</h3>
This is a group of equations which may have none, one or more solutions.
From the list of given options, the system of equations that has one solution is:
–2x+ 7y = –5 and 2x +7y = –9
This is so because, the solution is (-1,-1)
However, the other systems have infinite many solutions

Answer:
1
Step-by-step explanation:
(8^1)^0
We know that a^b^c = a^ (b*c)
8^1 ^0 = 8^(1*0) = 8^0 =
Anything raised to the 0 power is 1
