Answer:
For this case we want to test if in a certain city in the U.S. are different from the proportion of the general population of young adults in the U.S 0.16 (alternative hypothesis) and the best system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem

Answer:
9.1 = a+4
Step-by-step explanation:
The right side has two different values, variable <em>a,</em> constant 4.
The left side has the constant 9.1.
If both sides are equal, then
a + 4 should equal 9.1
The one that I got to say I love it but it's not a good thing lol I just got it off of lol lol I got my phone number and my phone got a lot to get back and I'm just trying it out for my classes but it's still working and
Answer:
its a square, so all sides similar
28. SV = RT/2 = 5.7/2 = 2.8
29. RT^2 = RQ^2 + QT^2
--> RT = √
(4^2 + 4^2)
RT = √32 =5.7
30. perimeter of RVS = 2.8 + 2.8 + 4 = 9.7
Answer:
(-3/2, 4)
