The ages of two groups of karate students are shown in the following dot plots:
picture shown below:
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean
Answers
Answer:
Group A has less variability in the data.
Step-by-step explanation:
Since the range of group a is 10 (14 - 4), while group B has a range value of 19 (26 - 7) therefore group A has less variability in the data.

Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies.
Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie.
Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Camille buys a cake for $24.99.
She bought total 12 brownies.
She spend total $39.99 on cake and brownies.
So, to calculate the cost of each brownies
24. 99 + 12b = 39.99
12b = 39.99 - 24.99
12b = 15
b = $1.25

What are the advantages of taking a random sample instead of surveying an entire population?
Answers
Answer:
Answer is below
Step-by-step explanation:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied. This provides lack of bias towards the subject of the survey. It's overall more efficient, faster, and pushes the idea of simplicity through surveys.
Answer:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. It offers a chance to perform data analysis that has less risk of carrying an error. ... There is an equal chance of selection. ... It requires less knowledge to complete the research. ...

Part C: Greg had a rectangular vegetable garden that was 4 feet wide by 5 feet long. He increased the length of his garden by 2 feet and doubled the width. How many square feet larger is the area of his new garden compared to the area of his old garden? In a short paragraph, explain your answer in your own words.
Answers
part b: 60 inches
part c: 36 square feet
explanation: I multiplied 4 and 5 because area = l•w meaning the garden was originally 20 square feet. I then doubled the making it 8 and added two feet to the length making it 7 feet. Since area equals l•w i multiplied 8 and 7 getting 56 square feet. Since the question asked, “how many square feet larger,” I subtracted the new area, 56 square feet, by the old one, 20 square feet, and got 36 square feet.

Step-by-step explanation:

Answer:
--Educate the general public about activities that can lead to the spread of invasive species.
--Implement conservation methods to restore endangered populations of native animals to the area.
Explanation:
Invasive species is the species which comes from non-native land either due to human introduction or by their own. The invasive species compete with the members of the native species for resources.
The following are the steps will help prevent the introduction of invasive species into an area:
--Educate the general public about activities that can lead to the spread of invasive species.: The general public must be aware about the drawbacks and problems associated with the spread of invasive species.
--Implement conservation methods to restore endangered populations of native animals to the area.: The invasive species is likely to compete with the native species for resources. Hence, this can harm the population of the native species. This will kill the native species members to the extend that the species become endangered. The endangered members must be protected by using the conservation methods.

Step-by-step explanation:

The whole pizza will have 1908 calories.
What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area.
Given that, a 9-inch pizza has 30 calories per inch² we need to find that how many calories are in the entire pizza,
For finding the same we will find the area of the pizza,
Area = π × radius²
= 3.14 × 4.5²
= 63.6
Therefore, the area of the pizza is 63.6 in²
Since, 1 in² = 30 calories
So, 63.6 in² = 30 × 63.6 = 1908 calories.
Hence the whole pizza will have 1908 calories.

7. D
Step-by-step explanation:
36 doesn't go into 5
45 doesn't go into 4
60 doesn't go into 9
180/4 = 45
180/3 = 60
180/5 = 36
180/9 = 20
We can make this problem even easier by converting the denominator from 25 to 100. This can be done with multiplication (x4)
Whatever you do to the denominator, you must also do to the numerator, so if we multiply both sides by 4, we get 24/100, which is equivalent to .24
total: 81 pieces of jewelry
18/81 or 2/9 (divide numerator and denominator both by 9)
.67 = 67/100
.607 = 607/1000 or 60.7/100
.07 = 7% or 7/100
.067 = 6.7% or 6.7/100
Answer: the answer is letter "D" (180)
