The value of q(x) is 
The value of r(x) is 
Explanation:
The given expression is 
We need to rewrite the expression in the form of 
Simplifying the expression, we get,

Separating the fractions, we have,

-----------(1)
Now, we shall further simplify the term
, we get,

Common out 5 from the numerator, we have,

Substituting the value
in the equation(1), we get,

Thus, the expression
is in the form of 
Hence, we have,

and

Answer:
There is not sufficient evidence to support the claim μ > 54.4.
Step-by-step explanation:
1) 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".
2) Solution to the problem
On this case we want to test is
and the system of hypothesi on this case are:
Null Hypothesis: 
Alternative hypothesis:
On this case is our decision is FAILS to reject the null hypothesis then we can conclude that we don't have enough evidence to support the claim at the significance level provided. So the correct conclusion would be:
There is not sufficient evidence to support the claim μ > 54.4.
R is 8 my dude
Answer is r=8

Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
Answer:
Addition
Step-by-step explanation:
1) Add 275 to both sides.

2) Simplify 800 + 275 to 1075.

3) Switch sides.

We need to add in order to solve the equation.
so therefor, the answer is option G.
