List a specific example with a set and a subset.
Your example needs to be unique and in your own words.
Answers
Some examples:
The set of all animals in the world. A subset could be the group of all dogs. The set of all people in a country. A subset would be the group of people in a small town of that same country.Everything in a person's house (set), vs items located inside the person's kitchen only (subset).The set of parallelograms. A subset is the set of all squares.The set of rational numbers, in which the collection of integers is a subset.With each example, any item or person in the subset is also found in the original set (but not vice versa). For example, any dog is an animal but not the other way around.
If you were to draw a venn diagram, then the larger circle is the set of all animals, while the subset of all dogs is a smaller circle drawn completely inside the larger one.
Those examples listed above is of course not the complete list of set & subset combos. Feel free to get creative and think of others.

alex has 5 t-shirts in the drawer. 2 are white, and the rest are black. He will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. What is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?
Answers
Answer:
24%
Step-by-step explanation:
Lets consider it.
2 are white, and 3 are black.
2/5 chance of him getting white, and 3/5 chance of him getting black
So he successfully gets white on his first try.
2/5
Then he successfully gets black on his second try
2/5 * 3/5, or 6/25, or 24% of him getting white, then black.

The diameter of a circle measures 18ft what is the circumference of the circle? Use 3.14 for π and do not round
Answers
=======================================================
Work Shown:
d = diameter = 18 ft
pi = 3.14 approximately
C = circumference
C = pi*d
C = 3.14*18
C = 56.52
The distance around the circle's edge (aka perimeter) is about 56.52 feet
The result is approximate since pi = 3.14 is approximate.

What is the area, in square units, of
triangle UVW?
Answers
The Area of Triangle UVW be 16 squared units.
What is Area of Triangle?The area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Area of triangle I = [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 4 x 4
= 8 units
Area of triangle II= [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 2 x 6
= 6 units
Area of triangle III = [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 2 x 6
= 6 units
Area of rectangle = length x breadth
= 6 x 6
= 36units
Area of triangle UVW = Area of rectangle -(Area triangle I + Area of
triangle II +Area of triangle III)
= 36 - ( 8 + 6 + 6)
= 36 - 20
= 16 square units
Hence the Area of Triangle UVW = 16 square units.

Find the interquartile range (IQR) of the data in the dot plot below.
1,2,3,3,4,4,4,6
Answers
The value of interquartile range (IQR) of the data set which is plotted in the dot plot 1,2,3,3,4,4,4,6 is 1.5.
What is the interquartile range (IQR) of the data?The interquartile range (IQR) of the data is the middle half of the data, which contains 2nd and 3rd quartiles.
Interquartile range is the difference of third quartile and first quartile.
IQR=Q₃-Q₁
In the dot plot below, the data is given as,
1,2,3,3,4,4,4,6
The first quartile is the medium of the lower half, while the third quartile is the medium of the upper half. For the above data,
Q_1=2.5
Q_3=4
Thus, Interquartile range is,
IQR=Q₃-Q₁
IQR=4-2.5
IQR=1.5
Hence, the value of interquartile range (IQR) of the data set which is plotted in the dot plot 1,2,3,3,4,4,4,6 is 1.5.

Separate 79 into two parts such that 4 times the smaller exceeds the larger by 6.
1. Assign the variables.
2. Write the equations.
3. Solve the system.
4. Answer the question.
Answers
39 is separated into two parts 9 and 30
Step-by-step explanation:
The given is:
Separate 39 into two parts
4 times the smaller part exceeds the larger part by 6
Assume that the smaller part is x and the larger part is y
∵ 39 is separate into two parts x and y
∴ x + y = 39 ⇒ (1)
∵ x is the smaller part
∵ y is the larger part
∵ 4 times the smaller part exceeds the larger part by 6
- Multiply x by 4 and subtract y from it to get 6
∴ 4x - y = 6 ⇒ (2)
Now we have a system of equations to solve it
Add equations (1) and (2) to eliminate y
∵ (x + 4x) + (y - y) = (39 + 6)
∴ 5x = 45
- Divide both sides by 5
∴ x = 9
Substitute the value of x in equation (1) to find y
∴ 9 + y = 39
- Subtract 9 from both sides
∴ y = 30
∴ The smaller part is 9 and the larger part is 30
39 is separated into two parts 9 and 30
