(A)1
(B)2
(C)3
(D)4
(E)5
Answer: A
Explanation: In a distribution that is skewed to the right, the value of the Mean will be greater than the value of the median. Because the meaning of this distribution is 1.8 siblings, the median must be less than 1.8 siblings. The only other choice that is less than 1.8 is the value one, so the median must be one sibling.Mean will be greater than the value of the median. Because the meaning of this distribution is 1.8 siblings, the median must be less than 1.8 siblings. The only other choice that is less than 1.8 is the value one, so the median must be one sibling

PLEASE PLEASE HELP:: The scoop of an excavator holds 26 ft3 of sand. If the capacity of a freight car is 39 tons of sand and we know that 1 ft3 of sand weighs 0.5 tons, how many freight cars can be filled with 120 loads?
Answer:
40
Explanation:
Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion
26/x=1/0.5
If you simplify it, you should get x=13
Now that we know 26 ft3 of sand = 13 tons, we should multiply it with 120 number of loads
13*120=1560
Then, we have to divide 1560 by 39 which should give your answer 40
Hope this works!
Freight cars can be filled with 120 loads is 40
How is load percentage calculated?
The load factor percentage is derived by dividing the total kilowatt-hours (kWh) consumed in a designated period by the product of the maximum demand in kilowatts (kW) and the number of hours in the period.
Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion
26/x=1/0.5
If you simplify it, you should get x=13
Now that we know 26 ft3 of sand = 13 tons, we should multiply it with 120 number of loads
13*120=1560

Tara mows lawns as a summer job. She
charges $9.50 for each lawn plus $2.50 for
every hour she works. The gasoline she needs
to mow an average lawn costs $1.85. Write an
expression for the profit Tara makes from
cutting a single lawn.
Answer:
9.50+(2.50x)1.85
Explanation:
I think this might be it because you don't really get the time she works for a lawn
Answer:
7.65 + 2.50h
Explanation:
The original expression for finding her profit is:
($9.50x + $2.50h) - 1.85x
x being the number of lawns she mows
h being the number of hours she works
If she were to only mow one lawn, the expression would be:
($9.50(1) + $2.50h) - 1.85(1)
h remains constant because we do not know the number of hours she works for
The above expression simplified:
($9.50 + $2.50h) - 1.85
So, I do... $9.50 - 1.85 to get...
$7.65 +$2.50h

Take advantage of the free Wi-Fi available on most college campuses. The correct option is C.
What is technology?Technology refers to the tools, techniques, and processes that are used to create, develop, and improve products, services, and processes.
It encompasses a wide range of fields such as electronics, telecommunications, software, computers, and robotics.
College campuses typically offer free Wi-Fi for their students, which can be used to access the internet and other resources on a laptop, tablet, or smartphone.
Using these resources can help cut down on technology expenses, as students can use their own devices instead of purchasing new ones or relying on friends to borrow theirs.
Additionally, using a smartphone for communication needs may not be as efficient or practical as using a laptop or tablet, and using a typewriter is an outdated technology that is not commonly used anymore.
Thus, the correct option is C.

4. An organization that strives to hold agencies accountable for truth in news reporting plans to select a random sample of 100 news stories from major U.S. news agencies in order to estimate the proportion of news stories produced by major U.S. news agencies that contain false information. A 90 percent confidence interval for the proportion of all news stories that contain false information will then be constructed. Before selecting the sample, the organization determines that they want to make the margin of error as small as possible. Which of the following is the best way for them to decrease the margin of error?
(A)Increase the confidence level to 95%.
(B)Increase the confidence level to 99%.
(C) Include a wider diversity of sources, such as local and international news agencies.
(D)Include news stories over a broad period of time, such as over the past decade.

3. The phrase, household penetration, describes the percentage of households that purchase a particular item. The household penetration for toilet paper is 97%. You survey a random sample of 50 households and want to compute the probability that at least one of the households does not purchase toilet paper. Which of the following is appropriate for modeling this distribution?
(A)Binomial distribution
(B)Geometric distribution
(C)Normal distribution
(D)t distribution
(E)Chi-square distribution
Answer:
A) Binomial Distribution
Explanation:
This situation is binary because there are two options. Either success (buy toilet paper) or failure (do not buy toilet paper). The trials are independent, there are a fixed number of trials, and the probability of success remains the same for each trial. Therefore, it is a binomial distribution.
