Rewrite 8/15 and 11/20 so that they have a common denominator.
Answer:
32/60 and 33/60
Step-by-step explanation:
Common Denominator is 60.
8x4=32
15x4=60
8/15= 32/60
11x3=33
20x3=60
11/20= 33/60
Consumers Energy states that the average electric bill across the state is $67.16. You want to test the claim that the average bill amount is greater than $67.16. The hypotheses for this situation are Null Hypothesis: μ ≤ 67.16, Alternative Hypothesis: μ > 67.16. If the true statewide average bill is $51.28 and the null hypothesis is not rejected, did a type I, type II, or no error occur?
a. Type I Error has occured.
b. No error has occured.
c. We do not know the degrees of freedom, so we cannot determine if an error has occured.
d. Type II Error has occured
e. We do not know the p-value, so we cannot determine if an error has occured.
Answer:
B: No error has occured
Step-by-step explanation:
In statistical hypothesis testing, we have two types of errors namely Type I error and Type II error.
Type I error occurs when we reject the null hypothesis although it is true. Meanwhile, Type II error occurs when we fail to reject the null hypothesis null hypothesis even though it is false.
Now, we are given the null and alternative hypothesis as;
Null Hypothesis: μ ≤ 67.16
Alternative Hypothesis: μ > 67.16.
Where μ represents the statewide average bill.
We are also given the true statewide average bill is $51.28.
Now, the true statewide average bill falls within the range of the null hypothesis given.
Thus, we can't reject the null hypothesis since it is true.
Now, we are told the null hypothesis is not rejected and that is correct.
Thus, there is no error as it doesn't fall into the type I or the type II error.

This is a subtraction problem. We need to subtract 5/8 from 3/4. We need a common denominator of 8.
3/4 - 5/8 = 6/8 - 5/8 = 1/8
Answer: 1/8
Answer:
Malika runs 1/8 of a mile more than Andrew
Step-by-step explanation:
The easiest way to figure this out is by converting both of the fractions to have the same denominator. Do not convert them to decimals because the answer might not always turn out to be right.
If we keep Andrew's distance of 5/8 the same we can easily convert Malika's distance of 3/4 to the same denominator by multiplying it by two
[tex]\frac{3}{4} *\frac{2}{2} = \frac{6}{8}[/tex]
Now that the denominators are the same, we are able to subtract the fractions.
[tex]\frac{6}{8} -\frac{5}{8} = \frac{1}{8}[/tex]
Malika runs 1/8 of a mile more than Andrew
Charlie has some candy. He shares ten pieces with Betsy and is left with 24 pieces.
Which equation represents how many pieces of candy did Charlie originally have?
1 : x + 10 = 24
2 : x - 10 = 24
3 : x + 24 = 10
4 : x - 24 = 10
Answer:
2. x-10=24
Step-by-step explanation:
x is the unknown amount of candy that Charlie has.
He gives ten away (-10).
Now he has 24 pieces.
x-10 = 24

Find two positive angles and two negative angles that are coterminal with the given angle and less than 1080 but greater than 720.
Answer:
The correct answer is 450°, 810°, -270° and -630°.
Step-by-step explanation:
According to the given scenario, the calculation of the two positive angles and two negative angles i.e. coterminal is as follows:
The coterminal angles are the angles in which the difference could be 360 degrees or the multiples of 360 degrees
For 90 degrees, the two positive angles are
a. 90° + 360°
= 450°
450° + 360°
= 810°
b. The two negative angles are
= 90° - 360°
= -270°
-270° - 360°
= -630°
