PLS HELP ME IF YOU WANT A BRAINLIEST IM DOING THIS NOW and IDU, Students from Williams Middle School are also recycling aluminum cans. The data for the numbers of cans brought in each school day for a month were divided by quartiles and summarized in the box plot. Use the drop-down menus to choose the median, interquartile range, and range.
>Median:
>Interquartile range:
>Range:
Answer: Median: 18
Interquartile range: 4
Range: 18
Step-by-step explanation: The median line is at 18, the interquartile range is the difference between the ends of the box, 20 - 16 = 4. The range is the difference between the ends of the line, 28 - 10 = 18. Let's take a look at how the data can be compared, from the two schools using the box plot.
From the information provided, it is clear that the
Median = 18Interquartile range = 4Range = 18How do we arrive at the following above?By observation, the median line is at 18. Note that the median of a distribution is the quantity that lies at the midpoint of a frequency distribution.
The interquartile range is the variance between the quantity at the end of the box, 20 - 16 = 4. The interquartile range (IQR)is defined as the mid 50% of the values in distribution when arranged from the lowest to the highest.
The range is defined as the difference between the quantities at the terminal points of the line. Hence, 28 - 10 = 18.

Factor each trinomial completely.
4x^2 - 25b^2 and x^2 - 81
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
The factorization of the trinomial are;
a. 4x² - 25b² = (2x + 5b)(2x - 5b)
b. x² - 81 = (x + 9)(x - 9)
What is the factorization of the trinomial?To factor the trinomial 4x² - 25b², we can use the difference of squares formula, which states that a² - b² can be factored as (a + b)(a - b).
Applying this formula to 4x² - 25b², we have:
4x² - 25b² = (2x)² - (5b)²
Now, we can rewrite the trinomial as a difference of squares:
4x² - 25b² = (2x + 5b)(2x - 5b)
Therefore, the trinomial 4x² - 25b² can be factored as (2x + 5b)(2x - 5b).
To factor the trinomial x^2 - 81, we can use the difference of squares formula once again:
x² - 81 = x² - 9²
This can be written as a difference of squares:
x² - 81 = (x + 9)(x - 9)
Thus, the trinomial x² - 81 can be factored as (x + 9)(x - 9).

If a pool table measures 4 ft by 8 ft , what is the diagonal length from the bottom right pocket to the nearest tenth?
Answer:
8.9 ft
Step-by-step explanation:
Use Pythagorean theorem,
a² + b² = c²
√(a² + b²) = c
The diagonal is the hypotenuse of the rectangular pool table.
So,
√(4² + 8²) = c
√(16 + 64) = c
√(80) = c
8.944... = c

The center of a circle is (5,-3) and its radius is 4. Which point lies outside of the circle?
Answer:
-1
Step-by-step explanation:
The equation of a circle gives the positions of points inside or on its circumference. A point is outside the circle if the substitution in the equation results in a value greater than the square of the circle's radius.
Explanation:To understand this, we need first to understand the equation of a circle which is defined in the format (x-a)² + (y-b)² = r², where (a,b) is the center of the circle and r is the radius.
In this case, (a,b) = (5,-3) and r = 4. So, the equation of the circle becomes (x-5)² + (y+3)² = 16. Any point (X,Y) that satisfies this equation is inside or at the circumference of the circle. If the computation yields a result greater than 16, the point is outside the circle.
Let's take a point for example: (3,-1). Substituting the values gives (3-5)² + (-1+3)² = 4 + 4 = 8 which is less than 16, hence, lies inside the circle. But for a point like (10,0), it results in (10-5)² + (0+3)² = 25 + 9 = 34 which is greater than 16, so the point (10,0) is outside the circle.

A pot of piping hot stew has been removed from the stove and left to cool.
The relationship between the elapsed time, m, in minutes, since the stew was removed from the stove, and the
temperature of the stew. T(m), measured in C is modeled by the following function.
T(m) = 20 + 50 - 10-0.0477
How many minutes will it take for the stew to cool to a temperature of 30°C?
Round your answer, if necessary to the nearest hundredth.
minutes
Answer: 17.47 minutes
Step-by-step explanation:
To find the number of minutes it will take for the stew to cool to a temperature of 30°C, solve the given nonlinear equation or graph it to find the intersection point.
Explanation:The given function that models the relationship between the elapsed time, m, in minutes, and the temperature of the stew, T(m), is:
T(m) = 20 + 50 - 10^(-0.0477m)
To find the number of minutes it will take for the stew to cool to a temperature of 30°C, we need to solve the equation:
30 = 20 + 50 - 10^(-0.0477m)
By isolating the unknown variable, m, we can solve for it using logarithms or graphing. However, since the equation is nonlinear, graphing is a more intuitive approach. Graph the equation and find the x-coordinate at which the graph intersects with the y-coordinate 30. This value of m will give you the number of minutes it will take for the stew to cool to 30°C.

Samuel needs 2 boards to make a shelf. One board is 84 centimeters long
and the other is 45 centimeters long.
What is the total length of the shelf?
centimeters
What would your answer be in millimeters?
millimeters
Answer:
The length of the shelf is 129 cm or 1290 mm.
Step-by-step explanation:
Since Samuel will use the two boards to make the shelf, then the total length of the shelf is the sum of the lengths of each board. So in order to solve this problem we must do as shown bellow:
length shelf = length board1 + length board2
length shelf = 84 + 45 = 129 cm
In order to convert this to milimeters we must multiply the answer above by 10. So we have:
length shelf = 129*10 = 1290 mm
The length of the shelf is 129 cm or 1290 mm.
Answer: 129 cm = 1290 mm
Step-by-step explanation:
Hi, to answer this question we simply have to add the length of both boards.
Mathematically speaking:
Total length = 84 cm + 45 cm = 129 centimiters
Since:
1 cm = 10mm
To convert 129 cm to mm we have to multiply it by 10.
129 cm x 10 mm/cm =1290 mm

The polynomial p(x) = x^3 - 21x - 20 has a known factor of (x-5). Rewrite p(x) as a product of linear factors.
Answer:
p(x) = (x - 5)(x + 1)(x + 4)
Step-by-step explanation:
Using Synthetic division to find the quotient on dividing p(x) by (x - 5)
5 | 1 0 - 21 - 20 ← 0 to represent the coefficient of x² term
5 25 20
-----------------------
1 5 4 0 ← remainder is zero
quotient = x² + 5x + 4 = (x + 1)(x + 4)
p(x) = (x - 5)(x + 1)(x + 4)
The polynomial p(x) = x^3 - 21x - 20 can be written as a product of linear factors as follows;
(x-5) (x+4) (x+1).
According to the question, the polynomial, p(x) = x^3 - 21x - 20 has a known factor of (x- 5).
To further factorise this polynomial such that it becomes a product of linear factors, we must first, perform the long division of x³ - 21x - 20 divided by (x-5).The polynomial long division is as in the image attached;
The result of the division of x³ - 21x - 20 by (x-5) yields;
x² + 5x + 4.The expression, x² + 5x + 4 can however be further factorised so that we have;
x² + 5x + 4 = (x+4) (x-1)Ultimately, the polynomial p(x) = x^3 - 21x - 20 can be written as a product of linear factors as follows;
(x-5) (x+4) (x+1).

A hot air balloon descended 2,250 feet in 15 minutes. Find the change in altitude per minute (show the process).
Answer:

Step-by-step explanation:
The change in altitude per minute will have the units of ft/min.
We see that we are given the number of feet: 2250 ft, as well as the number of minutes: 15 min.
So, to get ft/min, we can divide 2250 ft (the distance) by 15 min (time) to get the rate: 2250/15 = 150 ft/min
Thus, the change in altitude per minute is 150 ft/min.
Hope this helps!
