The middle 50% of the age of participants in the robotics competition falls between 13 and 31.
Explanation:The box plot represents the age distribution of participants in a robotics competition. The box extends from the lower quartile (Q1) to the upper quartile (Q3), which in this case are 13 and 31, respectively. The line within the box represents the median, which is 16. The whiskers represent the range of the data, ending at 11 and 33.
To find the middle 50% of the data, we need to determine the values that lie between Q1 and Q3. Therefore, the middle 50% of the age of participants in the robotics competition falls between 13 and 31.

If the diameter of a penny is 19.05 millimeters and the width of each penny is 1.52 millimeters, what is the approximate volume of the roll of pennies? Use 3.14 for π and round your answer to the nearest tenth.
Answer:
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Step-by-step explanation:
Given : diameter of a penny is 19.05 millimeters and the width of each penny is 1.52 millimeters.
To find : volume of the roll of pennies.
Solution : We have given that
Diameter of a penny = 19.05 millimeters.
Width of each penny = 1.52 millimeters.
Volume of cylindrical roll of penny = pi * r² * h
Where, r = radius , h =height
Radius = [tex]\frac{Diameter}{2}[/tex]
Radius= [tex]\frac{19.05}{2}[/tex].
Radius = 9.525 mm
Plugging the values of r , h and pi = 1.14.
Volume of cylindrical roll of penny = pi * r² * h
Volume of cylindrical roll of penny =3.14 * (9.525)² * 1.52
Volume of cylindrical roll of penny = 433.02 mm³
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Therefore, Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).

Apply the commutative property to 13 × 7 × 21 to rearrange the terms and still get the same solution
The commutative property in mathematics says that the order in which numbers are multiplied doesn't change the product. For example, using the commutative property, the product of 13 x 7 x 21 will be the same as 7 x 21 x 13, which is 1911.
Explanation:The commutative property is a fundamental concept in Mathematics which states that for multiplication and addition, numbers can be moved around (or commuted) without changing the result. For example, if you have the multiplication problem 13 * 7 * 21, thanks to the commutative property, you can rearrange this problem to: 7 * 21 * 13 or 21 * 13 * 7 or any other arrangement of these three numbers, and the result will remain the same.
Let’s see this in action:
Original arrangement: 13 * 7 * 21 = 1911
Changed arrangement: 7 * 21 * 13 = 1911
As you can see, regardless of how the terms were rearranged, the answer remained the same, thus demonstrating the commutative property.

Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read. Let P(t), left parenthesis, t, right parenthesis denote the number of pages to read P as a function of time t (measured in hours). Write the function's formula
The function's formula that represents the number of pages Naoya has left to read at time t would be P(t) = 570 - 55t.
Explanation:From the information given we know that Naoya reads at a rate of 55 pages per hour. After 4 hours of reading, he still has 350 pages left to read. This means that before he started reading, he had (55 pages/hour * 4 hours + 350 pages) = 570 pages in total. Since he reads at constant rate, the function that describes the remaining pages to read would be P(t) = 570 - 55t, where t represents the time in hours and P(t) is the number of pages left to read.

What is the quotient? x-1/7x2-3x-9
The quotient of the expression (x - 1)/(7x² - 3x - 9) cannot be determined
How to determine the quotient of the expression
From the question, we have the following parameters that can be used in our computation:
(x - 1)/(7x² - 3x - 9)
From the above, we have
degree of the numerator = 1
degree of the denominator = 2
The degree of the numerator is less than the degree of the denominator
This implies that the quotient of the expression cannot be determined

What is the complete factorization of r2 - 6r - 9s2 + 9? A) (r - 3 + 3s)(r - 3 - 3s) B) (r + 3 + 3s)(r - 3 - 3s) C) (r - 3 + 3s)(r - 3 + 3s)
We have factorized the expression 'r2 - 6r - 9s2 + 9' into (r - 3)^2 - (3s)^2 and then used the difference of squares formula to find the factorization as (r - 3 + 3s)(r - 3 - 3s). So the correct answer is option A)
Explanation:The question asked for the complete factorization of the expression r2 - 6r - 9s2 + 9. To factorize this, we can rewrite it into the formula form of a perfect square, which is a^2 - 2ab + b^2 = (a - b)^2.
Our expression fits this form when a = r and b = 3s. Following this, we can rewrite the expression as (r - 3)^2 - (3s)^2 = (r - 3 + 3s)(r - 3 - 3s). Therefore, the correct answer is option A) (r - 3 + 3s)(r - 3 - 3s)

Solve for y in terms of x.
2/3y - 4 = x
Please help . Time is critical for me in school rn
Answer:
[tex]y=\frac{3}{2}(x+4)[/tex]
Step-by-step explanation:
We are given
[tex]\frac{2}{3}y-4=x[/tex]
Since, we have to solve for y
so, we will isolate y on anyone side
Firstly, we add both sides by 4
[tex]\frac{2}{3}y-4+4=x+4[/tex]
[tex]\frac{2}{3}y=x+4[/tex]
Multiply both sides by 3
[tex]3\times \frac{2}{3}y=3\times(x+4)[/tex]
[tex]2y=3\times(x+4)[/tex]
now, we can divide both sides by 2
and we get
[tex]y=\frac{3}{2}(x+4)[/tex]
When paying off debts ,you should ___ .
A. pay the minimum
B.pay as much as possible
C.pay slightly more than the minimum
D.pay exactly half of what you owe
B.pay as much as possible
Step-by-step explanation:
Debts are unpaid money that a person owes to its lenders. The lender can be any bank or any other financial institution or any person.
Long accumulated debts on banks, if not paid, can result in a person filing for bankruptcy. So, it is always good if you pay your debts on time.
Paying minimum or slightly more than minimum amount will result in paying more in the near future. It is possible that if you always pay minimum amount, you will not be able to clear debts anytime soon.
So, its best that if you have money, always pay as much as possible to get rid of your debt.

Helen is 8 years older than Jane. Twenty years ago Helen was three times as old as Jane. How old is each now?
Let the age of the Jane be [tex] x [/tex]
So age of Helen = [tex] x [/tex] + 8
Twenty years ago,
Age of Jane = [tex] x [/tex] - 20
And age of Helen = [tex] x [/tex] + 8 - 20 = [tex] x [/tex] - 12
Helen was three times as old as Jane
[tex] x [/tex] - 12 = 3 ([tex] x [/tex] - 20)
[tex] x [/tex] - 12 = 3 [tex] x [/tex] - 60
Add - 3[tex] x [/tex] on both sides,
[tex] x [/tex] - 3 [tex] x [/tex] - 12 = 3 [tex] x [/tex] - 3 [tex] x [/tex] - 60
-2[tex] x [/tex] - 12 = - 60
Add 12 on both sides
-2[tex] x [/tex] - 12 + 12 = - 60 + 12
-2[tex] x [/tex] = - 48
Divide both side by -2
[tex] \frac{-2x}{-2}=\frac{-48}{-2} [/tex]

A woman is looking for a bigger square office. She finds an office twice the area of her current office. if the perimeter of her current office is 88feet, how many square feet is the new office?
The woman's new office has twice the area of her current office. By calculating the side length of the current square office from the perimeter and then finding the area, we determine the new office's area to be 968 square feet.
The question asks about calculating the area of a larger office which is twice the area of the woman's current office. Knowing the current office perimeter allows us to find the side length of the current square office and use it to calculate the area of both the current and the new office.
Calculate the side length of the current office from the given perimeter. The formula for the perimeter of a square is 4 × side length. Given that the perimeter is 88 feet, we divide by 4 to find that the side length of the current office is 22 feet. (88 ÷ 4 = 22)To find the area of the current office we square the side length (side length × side length). Thus, the area is 22 feet × 22 feet = 484 square feet.The new office has twice the area of the current one, so its area is 2 × 484 square feet = 968 ft².The area of the new, larger office is 968 ft².
