Activity
Part A

For his class survey, Walden chose the question, How many people live in your home, including yourself? He asked his friend Drake to help him with the survey. Walden asked 10 students in his class the question, and Drake posed the same question to 10 more students in their class.

Based on the responses, they wrote these data sets:

Walden’s data set: 2, 2, 2, 3, 3, 3, 3, 4, 4, 4

Drake’s data set: 3, 3, 4, 4, 4, 4, 5, 6, 7, 9

Question 1

Compare the two data sets. Do they have the same center, or is the center of Walden’s data set greater or less than the center of Drake’s data set?

Answer 1

Answer:

The center of Walden’s data, 3, is less than the center of Drake’s data set, 6.

Step-by-step explanation:

i got this answer^

Answer 2

Answer:

Part A) Question 1 The center of Walden’s data, 3, is less than the center of Drake’s data set, 6.

Part A) Question 2 Walden’s data ranges from 2 to 4, and Drake’s data set ranges from 3 to 9. Drake’s data set has a greater spread than Walden’s data set.

Part A) Question 3 The graph of Walden’s data set will be symmetrical about the center, and the graph of Drake’s data set will be skewed to the right.

Part A) Question 4 Walden’s data set doesn’t have any outliers. Drake’s data has an outlier with the value 9, which is at the higher end of the distribution.

Part B) Question 1 The center is 5.

Part B) Question 2 This data set has no spread at all. All the values are the same, so the difference of the highest value and the lowest value in the set is 0.

Part B) Question 3 All the data points would lie at the same point, 5. The graph would be a single bar at the value 5, with no other data points anywhere else.

Part B) Question 4 No. All the observations in the data set are the same, and the only answer to the question is 5. So there is no need to find the center, spread, or shape of the data set.

Part B) Question 5 No, Walden was not asking a statistical question because all the people living in the same house would give him the same answer to his question. So the question did not allow for multiple answers among the population that it was posed to.

37.68 square in.
113.04 square in.
28.26 square in.

Answers

Answer:

The answer is 28.26 square in

Step-by-step explanation:

As, the diameter if the top = 6 inches

And the area of a circle = 3.14(pi) x radius^2

So here radius = Diameter /2 = 6/2 = 3

So radius = 3 inches

So area = 3.14 x (3)^2

= 3.14 x 9

= 28.26 square in

the answer is 28.26 square inch.

Bella has $26.00 to spend at a craft store. She buys fabric that costs $18.62. She also wants to buy knitting needles for $7.32, silk flowers for $7.38 or oil paints for $8.48. Use the equation $18.62 + c = $26.00, where c is the item cost, to find the most expensive item Bella can buy. Show your work and explain how you found your answer. Be sure to write your answer in a complete sentence.

Answers

The answer is 3 dollars and 07 cents
Answer: Silk Flowers ($7.38)

Explanation:
STEP ONE:
Subtract 18.62 from 26
26-18.62=7.38
STEP TWO:
Match up the answer to the costs
7.38 > Needles (7.32)
7.38 < Paints (8.48)
7.38 = Flowers (7.38)
Evidently, the flowers are the most expensive thing Bella can buy.
STEP THREE:
Check your answer
18.62 + 7.38 = 26
Equation checks out
FINAL ANSWER:
Silk Flowers

28 miles per 4 hours, so you divide them both by 4 and get 28 divided 4

and 4 divided by 4. so its 7/1 which just equals 7. please correct me if im wrong good luck.

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1

New equation: 7 / 1

Simply the newer equation and you have your answer

7 ÷ 1 = 7 / 1 ➡️ 7

A pan balance has 3 cubes on one pan and 11 cubes on the other pan. Lucy thinks she should add 7, 8, 9, or 10 cubes to make the pans balance. How can you use the equation 3 + c = 11 to find the number of cubes Lucy should add?

Answers

Answer:

8

Step-by-step explanation:

11-3=c

c=8

The number of cubes Lucy should add is 8.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a pan balance has 3 cubes on one pan and 11 cubes on the other pan.

The equation to represent the situation is 3+c=11

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, c=11-3

c=8

Therefore, the number of cubes Lucy should add is 8.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3
