Answer:
The first one
Step-by-step explanation:
Interval notation(-infinitive, -4)
The appropriate hypothesis which is used to test the dropout rate are 
and 
.
Given Drop out rate through 24 year old who are not enrolled is 8.1%, sample size=1000 and we have to find the hypothesis to test the drop out rate of the school.
The variable which needs to be studied is X=Number of individuals with age between 16 and 24 years old that are high school dropouts.
The parameter of interest is the proportion to high school drop outs is p.
Sample proportion=
=0.065
The hypothesis can be formed as under:
(null hypothesis)
( alternate hypothesis)
Null hypothesis is a hypothesis which is tested for its validity and alternate hypothesis is hypothesis which is opposite of null hypothesis means if null hypothesis is rejected then the alternate hypothesis will be true.
=
=-1.85
Hence the appropriate hypothesis are and .

Might Want to draw this and Its very long but Hope it helped :)
Answer:
The sides are all of the same length - let's say a. The angles are all the same too, and since the angles must add up to 180∘, we conclude that the three angles in the equilateral triangle are equal to 180∘/3=60∘.
Now we do something sneaky. We draw a line all the way down from the top vertex of the triangle to the midpoint of the bottom line.
This new line cuts our equilateral triangle in half. What are the angles in one half?
The angle at the bottom is 90∘.
One of the angles is the same as one of the angles in the original equilateral triangle, so it is 60∘.
So the third angle must be 180∘−90∘−60∘=30∘.
Now the hypotenuse of this new triangle is a, the side length of the equilateral triangle. And the length of the shortest side is a/2, since the line we drew cut the bottom line in half.
