The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units in your answer.
Answer:
[tex]\boxed {\boxed {\sf 48 \ meters }}[/tex]
Step-by-step explanation:
The perimeter is the sum of the side lengths.
A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is
[tex]p= 2l+2w[/tex]
The length is 20 meters and the width is 4 meters.
[tex]p= 2(20 \ m )+ 2(4 \ m )[/tex]
Multiply.
[tex]p= 40 \ m + 8 \ m[/tex]
Add.
[tex]p= 48 m[/tex]
The perimeter of the rectangle is 48 meters.
let f(x) = 1/x and g(x) = x² – 5x. What
two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.
Answer:
5,0
Step-by-step explanation:
f o g is a composite function, y values of g passed as x values into f.
f o g = 1/(x^2 - 5x)
in this case, the only way for the function to be undefined is when
x^2 -5x = 0
x(x - 5) = 0
x = 0 or x = 5

I need help please someone please
Answer:
f(x) - g(x) = 7x^4+2x^2-3x-10
Step-by-step explanation:
f(x) = 10x^4 + 2x^2 +1
g(x) = 3x^4 +3x +11
f(x) - g(x) = 10x^4 + 2x^2 +1 - ( 3x^4 +3x +11)
Distribute the minus sign
f(x) - g(x) = 10x^4 + 2x^2 +1 - 3x^4 -3x -11
Combine like terms
f(x) - g(x) = 7x^4+2x^2-3x-10

A study was conducted to investigate the effectiveness of a new aspirin-derivative in reducing pain. Results for randomly selected subjects are presented in the Assignment # 8 Excel worksheet. A lower score indicates less pain. The "before" value is matched to an "after" value and the differences are calculated ( on your excel worksheet ) . The differences have a normal distribution. Are the pain-reduction measurements, on average, lower after taking the new aspirin-derivative ? Test at a 1 % significance level.

Dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate of $7.99 for shipping, Drag numbers to complete an equation to find
the cost of each shirt, s. Each number may be used only once.
3
7.99
71.83
Answer:
3s+7.99= 71.83 .
Step-by-step explanation:
since there are 3 shirts you would multiply s by 3 so 3s. To me it looks like 7.99 is the constant and 71.83 is the total including this constant. so putting all of these together in y=mx+b format you get the equation 71.83= 3s+7.99

Maria tests the effectiveness of an anti-depression drug by recruiting 500 participants and randomly assigning half e participants to take Drug A for 1 month and the other half to take a placebo for 1 month. At the end of the month, depression levels are recorded. Overall, participants who received Drug A had depression scores of M-32.12, SD- 10.58 and those you received the placebo had depression scores of M- 34.29. SD 11.10, t(498) 2.17,p .01 (one tailed], d19. Faced with these data, Maria needs to write a report in which she interprets the data. Which of the following is the best summary of these data?
A. The p value is very small, showing that there is only a 1% chance of a Type l error. we can be 99% confident that the drug significantly reduces depression.
B. The results of the t-test are significant, but the effect size is small. This study should be replicated with a larger sample size to increase statistical power.
C. The results of the t-test are significant, but the effect size is small. The drug does lower depression, but it is not clear if the reduction is enough to warrant use of the drug.
D. The small p value and the small effect size suggest that the observed difference between the drug adplacebo groups are likely to be due to sampling error. This study should be replicated with a larger sample size.
Answer:
D. The small p value and the small effect size suggest that the observed difference between the drug placebo groups are likely to be due to sampling error. This study should be replicated with a larger sample size.
Step-by-step explanation:
The p value is determined for any test before making a conclusion. If the p-value is smaller than critical value then we reject the null hypothesis which means that drug is not effective for the reducing depression. A very small p-value usually lesser than 0.05 indicates strong evidence against the null hypothesis.

1. Delia brushes her teeth 6 hour
each day.
Units of Time
1 week = 7 days
1 hour = 60 minutes
Write and solve an equation to find
how many minutes Delia brushes
her teeth in 1 day. Then use that to
find the number of minutes she
brushes her teeth in 1 week.
Answer:
Answer:
PART A: 28 hours, PART B: 16800 minutes
Step-by-step explanation:
Delia Brushes her teeth = 1/6 hour
PART A
Total Week= 1 week
Total number of days in a week= 7 days
Total number of hours in a day= 24 hours
Total number of hours in a week= 24× 7 hours
Total number of hours in a week= 168 hours
Number of hours that Delia brushes her teeth = × 168 hours
Number of hours that Delia brushes her teeth = 28 hours
Hence, the correct answer is 28 hours
PART B
Total number of days in a week= 7 days
Total number of hours in a week= 168 hours
Total number of minutes in a week= 168 × 60
Total number of hours in a week= 100800 Minutes
Number of minutes that Delia brushes her teeth = × 100800
Number of hours that Delia brushes her teeth = 16800 minutes
Hence, the correct answer is 16800 minutes

9514 1404 393
Answer:
36π mm²
Step-by-step explanation:
You know that (ab)² = a²b². This tells you that ...
πr² = π(6 mm)² = π(6² mm²) = 36π mm²
The units of area are square millimeters (mm²).

Additional comment
For a variety of reasons, I find it is often helpful to keep units of measure with the associated number. It serves as a check on the arithmetic, among other things. If the units don't make sense, chances are good that the math doesn't make any sense.
It should be fairly obvious that if linear dimensions are in millimeters, then the corresponding area dimensions will be square millimeters. (Volume will be cubic millimeters.)
In the math, the units can be treated in the same way as any other variable. This tells you, for example, that you can only add (or subtract) measures with the same units (like terms). Division can be used to cancel same units, or to get from volume to area, for example (mm³/mm = mm²).
