or
r=-37
Step-by-step explanation:
Answer:
Null Hypothesis: p = 0.65.
Step-by-step explanation:
The null hypothesis is the expected population population, from an assumption deriving for example, from a previous experiment.
According to a researcher who was quoted in a New York Times article in March, 2011, 65% of U.S. community college students must take at least one remedial course in English
This means that the expected value of the population proportion is
, which is the null hypothesis.
Null Hypothesis: p = 0.65.
<span>h = –16t 2 + 64t + 8
since both the launch height and target height are identical we can say height is 0
solve for t
0 = -16t^2 + 64t +8
-8(2t^2-8t-1) =0
divide both sides by -8
2t^2-8t -1 = 0
t = 4.12 and -0.121
since it can't be a negative number:
t = 4.12 seconds ( round off as needed)

It's rational
Rational numbers are numbers that you can put into the form of a/b.
