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?

Step-by-step explanation:
i got this answer^
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.

Part B
What percentage of those surveyed have a pet lizard?
Part C
What percentage of those surveyed have both a snake and a lizard?
Answers
Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%
Important Information : Percentage people having pet snake = 40%
C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)
Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%B] Total percentage of people having pet lizard = 10% + 45% = 55%

Answers
Answer:
72%
Step-by-step explanation:
18/25 = 0.72
0.72 x 100 = 72
Answer:
72%
Step-by-step explanation:
Step 1 we make the assumption that 25 is 100% since it is our output value
Step 2 we next represent the value we seek with x
Step 3 from step 1, follows that 100%=25
Step 4 in the same vein, x%=18
Step 5 this gives us a pair of simple equations: 100% = 25(1)
X%= 18(2)
Step 7: taking inverse of both sides yields
X%\100% = 18/25
—> = 72%
Therefore, 18 is 72% of 25

Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.
The length of the bridge is about ____ kilometers.
Answers
b:8.04 km
The roadway is about 60.66 meters above the water.
The length of the bridge is about 8.04 kilometers.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
The length of the roadway above the water = 199 ft
1 ft = 0.3048 m
Multiply 199 on both sides.
199 ft = 60.66 m
The bridge has a length of 26,372 feet.
1 ft = 0.0003048
Multiply 26372 on both sides.
26372 ft = 26372 x 0.0003048
26372 ft = 8.04 km
Thus,
The roadway in meters is about 60.66 meters above the water.
The length of the bridge in km is about 8.04 kilometers.

Lily likes to collect records. Last year she had 10 records in her collection. Now she has 13 records. What is the percent increase of her collection?
Answers
Answer:
30%
Step-by-step explanation:
We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.
13/10 = 1.3
1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)
0.3 = 3/10 = 30%

(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over 30 EndFraction = Negative StartFraction 4 over 15 EndFraction
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over Negative 30 EndFraction = StartFraction 4 over 15 EndFraction

Answers
Answer:
Step-by-step explanation:
The correct pairs of equivalent expressions are given below.
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
What is the expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have given that,
All the expression are,
(5 + 2b)+(2b + 3/2)
(-14 + 3/2b)-(1 + 8/2b)
(-10 + b)+(7b -5)
(7/2b - 3)-(8 + 6b)
Now, We have to determine the equivalent expression as;
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
Thus, The correct pairs of equivalent expressions are given below.
⇒ (5 + 2b)+(2b + 3/2) = 4b + 13/2
⇒ (-10 + b)+(7b - 5) = 8b - 15
⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b
⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11
