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%)
Answer: 15 pongs you say?
Step-by-step explanation:
Mapping the triangle on one another simply means you use rigid transformations, which involve scaling. So the second triangle is congruent.
Since 3 is the shortest side, 27 pairs with three, so:
27/3 = 9
The second triangle is 9 times larger.
Using this we can do:
5 * 9 = 45
6 * 9 = 54
since 6 is the largest side, 54 is our answer! Or is it?
Note that this is a right triangle, so we use the Pythagorean theorem to find the hypotenuse.
=
so 9*sqrt(34) is our answer

the y intercepts put x=0
So the production of the tomatoes may be one of the element that the price of its may increased or decrease. So if the production of tomatoes will decrease and the demand is higher than the supply the possible effect to its is the increase of price of the tomtatoes
Answer:
$16.10
Step-by-step explanation:
Simply take the original cost and multiply it by the percentage to get the tip amount then add it all together.
14 × 15% = 2.1
14 + 2.1 = 16.1
This means the haircut would cost a total of $16.10.
