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%)
1.43 is the answer because 3.27-1.84=1.43
Answer:
MN = 48
Step-by-step explanation:
Since AB is a diameter , so it divides MN into 2 equal parts i.e. MO = NO
7x-4 = 6x
7x-6x = 4
x = 4
Now
MN = MO + NO
MN = 7x-4+6x
MN = 7(4)-4+6(4)
MN = 28-4+24
MN = 48
The x axis is the one going this way : ——— the y is the opposite going up so you just have to number it and add the dots
Answer:4
Step-by-step explanation:if you replace each "x" in the equation with the given x (-15) then it should go as such:
2(-15-5)-(3(-15)+1)
Then simplify
2(-20)-(-45+1)
2(-20)-(-44)
-40-(-44)
-40+44
