you keep the 2k
so 5(-45)5x is 5 * -45*5 = -1125
the answer is 2k+-1125x
10 1/2 ft=2x-18 in
convert ft to in--10 1/2ft=126 in
126=2x-18
2x=144
x=<em>72 inches or 6 feet</em>
Answer:
-3 and 11
Step-by-step explanation:
Answer:
The null hypothesis is
, in which x is the proportion tested.
The alternative hypothesis is 
Step-by-step explanation:
A recent article in a university newspaper claimed that the proportion of students who commute more than miles to school is no more than x.
This means that at the null hypothesis, we test if the proportion is of at most x, that is:

Suppose that we suspect otherwise and carry out a hypothesis test.
The opposite of at most x is more than x, so the alternative hypothesis is:

Answer:
x=67
y=40
The angles equal 63 and 117
