Answer:
17
Step-by-step explanation:
The median of a data set can simply be thought of as the middle value/number.
You could list all values out:
16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 18, 18, 18, 19, 19, 19
and then find what the middle of 24 would be (There are an even number of values, so both numbers in places 12 and 13 are considered the median, meaning that we find the average of these two values to be our median)
the 12th value is 17, and the 13th value is 17, meaning that the median is 17.
-----------------------
You could also calculate what would be 12 "in" from the data set. The first 4 values are 16 (12 - 4 = 8 ; 8 values left to go until middle) And then take the remaining 8 places to find the 12th value (9 - 8 = 1), so you know that the 12th value is the 8th repetition of 17.
There is still one more value of 17, so that is also the 13th placed value.
In this method of finding the middle number, the median is still 17.
The median of these ages is 17.
What is the median?The median exists as the middle number in a sorted checklist of numbers and can be better descriptive of that data set than the average. The median exists sometimes utilized as objected to the mean when there exist outliers in the sequence that might skew the average of the values.
The median of a data set can only be considered as the middle value.
Let the values be 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 18, 18, 18, 19, 19, 19
To find the middle of 24 would be (There exist an even number of values, so both numbers in places 12 and 13 exist considered the median) the 12th value stands at 17, and the 13th value stands at 17, indicating that the median exists at 17.
You have to calculate an estimate of 12 "in" from the data set. The first 4 values exist 16 (12 - 4 = 8; 8 values left to go until middle)
Consider the remaining 8 places to estimate the 12th value (9 - 8 = 1)
The 12th value exists in the 8th repetition of 17.
Therefore, the median of these ages is 17.

Step-by-step explanation:
The diagram shows 3 identical circles inside a rectangle.
Each circle touches the other two circles and the sides of a rectan
as shown in the diagram.
The radius of each circle is 2 mm.
Work out the exact area of the rectangle.
Give your answer in the form a√3 + b
where a and b are integers.
Based on the calculations, the exact area of this rectangle is equal to 16√3 + 32 mm².
How to calculate the area of a rectangle?Mathematically, the area of a rectangle can be calculated by using this formula:
Area = Length × Width
Note: Radius (R) is equal to 2 mm.
Joining the center of the circles would form an equilateral triangle with side length of 2R. Also, the height of the equilateral triangle is given by:
Height = √2R² - R²
Height = √3R
For the length and width of this rectangle, we have:
Length = R + 2R + R
Length = 4R
Width = 2R + height of equilateral triangle
Width = 2R + √3R
Width = (2 + √3)R
Therefore, the area of a rectangle becomes:
Area = 4R × (2 + √3)R
Area = 4(2 + √3) × R²
Area = 4(2 + √3) × 2²
Area = (8 + 4√3) × 4
Area = 16√3 + 32 mm² ≡ a√3 + b
In conclusion, a = 16 and b = 32.

The area of a rectangular shop in the mall is 160 square meters. The perimeter is 52 meters. What are the dimensions of the shop?
Answer:
width = 10 m
length = 16 m
Step-by-step explanation:
Formula
[tex]\textsf{Area of a rectangle} = wl[/tex]
[tex]\textsf{Perimeter of a rectangle}=2(w+l)[/tex]
(where [tex]w[/tex] is width and [tex]l[/tex] is length)
Given:
Area = 160 m²Perimeter = 52 mSubstituting the given values into the formulae to create two equations:
[tex]\textsf{Equation 1}: \quad wl=160[/tex]
[tex]\textsf{Equation 2}: \quad 2(w+l)=52[/tex]
Rearranging Equation 1 to make w the subject:
[tex]\implies w=\dfrac{160}{l}[/tex]
Substituting expression for w into Equation 2 and solving for [tex]l[/tex]:
[tex]\implies 2\left(\dfrac{160}{l}+l\right)=52[/tex]
[tex]\implies \dfrac{160}{l}+l=26[/tex]
[tex]\implies 160+l^2=26l[/tex]
[tex]\implies l^2-26l+160=0[/tex]
[tex]\implies l^2-10l-16l+160=0[/tex]
[tex]\implies l(l-10)-16(l-10)=0[/tex]
[tex]\implies (l-10)(l-16)=0[/tex]
[tex]\implies l=10, 16[/tex]
According to Equation 1:
If length = 10 m ⇒ width = 16 mIf length = 16 m ⇒ width = 10 mAs width < length, the dimensions of the shop are:

A northbound train left at noon. Two hours later, a southbound train left the same station. At five o'clock the two trains were 210 miles apart. Find the rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train.
The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.
what is speed?
Speed is the time rate at which an object is moving along a path
Let the speed of southbound train is x miles/hour
so, northbound train has speed of x+10 miles/hour.
then, Speed of both train = Total distance/ total time
(x+10+x)=210/5
2x+10= 210/5

Find the interquartile range (IQR) for the following data set: 52, 60, 24, 36, 48, 52, 72
Answer:
24
Step-by-step explanation:
The interquartile range defines the difference between the third and the first quartile.
Let's put this data set in ascending order:
24, 36, 48, 52, 52, 60, 72
The median is 52. The median of both the lower (1st quartile) and upper half (3rd quartile) of the data is 36 and 60.
Now we can subtract the first quartile from the third quartile (60 - 36) to get the interquartile range of 24.

George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30 minus x) feet. The diagram below shows his plan.
Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.
A rectangle labeled Dog run has a length of 30 feet and width of (30 minus x) feet.
How many feet of fencing will George need for the dog run?
The length of the fencing needed for the dog run will be 76 feet
What is the length?
The measure of the size of any object or the distance between the two endpoints will be termed the length.
Given that:-
Area of Dog Run = 240
Length of Dog Run = 30
The solution will be done as below:-
Width of Dog Run = 30 - x
Area of Dog Run: 30 * (30 - x) = 240
240 / 30 = 30 - x
8 = 30 - x
x = 24
Width of Dog Run = 8
How many feet of fencing will George need for the dog run?
Perimeter of Dog Run = 2Length + 2Width
Perimeter of Dog Run = (2 * 30) + (2 * 8)
Perimeter of Dog Run = 60 + 16
The perimeter of Dog Run = 76
Therefore the length of the fencing needed for the dog run will be 76 feet

Write the following expression without negative exponents and without parentheses.
(9x)^-1
Answer:
1/9x
Step-by-step explanation:
The parenthesis around the 9x means that the -1 exponent goes to the whole thing (the 9x) To "fix" a negative exponent push the 9x across a fraction bar to make the exponent positive. When you push the 9x down across a fraction bar that leaves a 1 on top of the fraction, that has nothing to do with the 1 exponent. Its a 1 on top because when you push the 9x down there is nothing left on top so it is a 1.
(9x)^-1
= 1/9x
To be clear, this is a 1 one top and a 9x on the bottom of a fraction.
