what is the definition of a subset and how does it work?
A subset is when all elements of any set A are present in another set B. Its working has been explained below.
Let us take two sets on random i.e., set A and set B. If we find that all elements of set A can be found in set B as well, we deem it to be a subset of set B. If we were to explain in simpler terms, we can say that set A is a part of set B.
Let us further assume that set A has the elements {1,2,3} and set {1,2,3,4,5,6}. From what we can see is that all elements in set A are also present in set B. This means that set A is a subset of set B.

Randall is saving money to buy a bicycle. He has 37.80 in his savings account and saves 20% of his paper route earnings each week after 10 weeks, he has 87.80 in his savings account. How much does Randall earn each week from his paper route.
Answer:
$25
Step-by-step explanation:
Let's first subtract the savings account
87.80 - 37.80 = $50
Which means after 10 weeks, she saves $50
$50/10weeks = $5/1 week
Now they save 20% of the route. Which means $5 is 20% of the route.
To get to 100% we multiply 20% by 5.
That means we multiply the $5 by 5 also, giving us $25.
Miss Nestor is randomly passing out books to her students for free reading time. In her book basket, she has 10 mysteries, 2 historical fiction novels, and 8 biographies. If there are 10 students in Miss Nestor's class for free reading time today, which of the following is the best prediction of the number of students who will receive historical fiction novels for free reading time?
Answer:
1
Step-by-step explanation:
To predict the number of students who will receive historical fiction novels for free reading time, we need to use the concept of probability. Probability is the likelihood of an event occurring, and is expressed as a number between 0 and 1.
In this case, there are a total of 10 + 2 + 8 = 20 books in Miss Nestor's basket. Of these, 2 are historical fiction novels. Therefore, the probability of a student randomly selecting a historical fiction novel from the basket is:
P(historical fiction) = number of historical fiction novels / total number of books
P(historical fiction) = 2/20 = 0.1
This means that there is a 10% chance that a student will randomly select a historical fiction novel from the basket. To predict the number of students who will receive historical fiction novels, we can multiply the probability by the total number of students:
Number of students receiving historical fiction = Probability of historical fiction * Total number of students
Number of students receiving historical fiction = 0.1 * 10
Number of students receiving historical fiction = 1
Therefore, the best prediction of the number of students who will receive historical fiction novels for free reading time is 1.

Lamonte is going to invest $48,000 and leave it in an account for 17 years. Assuming the interest is compounded continuously, what interest rate, to the nearest tenth of a percent, would be required in order for Lamonte to end up with $120,000?
The interest rate that would be required is 5.39%. The solution has been obtained by using concept of compound interest.
What is compound interest?
Both the principal and the interest that has accumulated over the preceding period are taken into account when interest is calculated. In contrast to simple interest, which does not take the principal into account when calculating the interest for the following month, compound interest does. Compound interest is usually represented in algebra by the letter C.I.
We are given that Lamonte is going to invest $48,000 and leave it in an account for 17 years. She wants to end up with $120,000.
So, from this we get the equation as
120,000 = 48000e¹⁷ⁿ ( n is the interest rate)
Solving this, we get
e¹⁷ⁿ = 2.5
n = 5.39%
Hence, the interest rate that would be required is 5.39%.

If you have 2 moles of marbles how many marbles do you have
If the average mass of one marble is 5 grams, and you have 2 moles of marbles, you would have 2 marbles.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
The number of marbles you have will depend on the total mass of the marbles, as the number of moles is a measure of the amount of substance (in this case, marbles) rather than the actual number of marbles.
To calculate the number of marbles, you would need to know the mass of one marble, and then divide the total mass of the marbles by the mass of one marble.
For example, if the average mass of one marble is 5 grams, and you have 2 moles of marbles, you would first calculate the total mass:
mass = number of moles x molar mass
where the molar mass of a single marble is equal to its mass in grams, and the number of moles is given as 2:
mass = 2 moles x 5 grams/mole = 10 grams
Then, you can calculate the number of marbles by dividing the total mass by the mass of one marble:
number of marbles = total mass / mass of one marble
number of marbles = 10 grams / 5 grams/marble = 2 marbles
Therefore, if the average mass of one marble is 5 grams, and you have 2 moles of marbles, you would have 2 marbles.

What is the area of the sidewalk around the pool?
Answer:
392ft²
Step-by-step explanation:
We need to find out the area of the side walk .The area of the sidewalk will the difference of the areas of rectangles ABCD and EFGH .
The dimensions of rectangle EFGH is 35ft * 14ft
So it's area would be ,
A = l*b
A = 14ft * 35ft
A = 490ft²
Now the length of the rectangle EFGH will be,
l = 35ft + 2*3.5ft
l = 35ft + 7ft
l = 42ft
Again,its breadth will be,
b = 14ft + 2*3.5ft
b = 14ft + 7ft
b = 21ft
So it's area would be,
A = l * b
A = 42ft * 21ft
A = 882ft²
Therefore the area of the sidewalk will be,
ar(sidewalk) = ar(ABCD) - ar(EFGH)
ar(sidewalk) = 882ft² - 490ft2
ar(sidewalk) = 392ft²
and we are done!

what is the difference between relative frequency and cumlative relative frequency
The difference between relative frequency and cumulative relative frequency is that relative frequency is the ratio of the frequency of a particular value in a dataset to the total number of values, expressed as a percentage. Cumulative relative frequency is the sum of all relative frequencies up to a certain point in the data set.
For example, if a data set has 8 values and 4 are the same, the relative frequency would be 50%. Cumulative relative frequency would be 50% at this point since it is the sum of all relative frequencies up to this point in the data set. If there were another 4 of the same values after this point, the relative frequency would remain at 50%, but the cumulative relative frequency would increase to 100% since it includes all previous relative frequencies.
