Step-by-step explanation:
We have to find the slope of a straight line through points (-5,-10) and (-1,5).
Now. we know the slope of a straight line through the points (
) and (
) is given by
.
So, in our case (
) ≡ (-5,-10) and (
) ≡ (-1,5).
Therefore, the slope of the line is
(Answer)

Answer: (80% , 85%)
Step-by-step explanation:
We know that, confidence interval for population proportion is given by :-
(p-E , p+E)
, where p = sample proportion , E = Margin of error.
Given : Proportion of elementary school teachers who are female = 82%.
The article also states the maximum error of their estimate = 3%.
Then, the 90% confidence interval for the proportion of elementary school teachers who are female will be :
(82%-2% , 82%+3%)
= (80% , 85%)
Hence, the resulting 90% confidence interval for the proportion of elementary school teachers who are female = (80% , 85%)
