Nico and Lorena used different methods to determine the product of three fractions.
Nico’s Method
Lorena’s Method
(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
Whose solution is correct and why?
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction.
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction.
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction

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%

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

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

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:
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.

Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Step-by-step explanation:
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).
The net change to her banking account balance is $83.22.
What is net change?The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
Given that, She spent $36.50 plus 8% tax. (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Hence, adding to the total cost.
64.42 +18.8 = $83.22
