CAN SOMEONE GIVE A EXPLAINATION ABOUT CLOSURE PROPERTY WITH A SIMPLE EXAMPLE THAT IS EASY TO UNDERSTAND
Answers
Explanation:
A set is "closed" for a particular operation if performing that operation on members of the set always gives a member of the set.
closed example
For example, the set {0, 1} is closed for multiplication:
0 × 0 = 0
0 × 1 = 0
1 × 1 = 1 . . . all result values are members of the set
Performing multiplication on any two members of the set gives a member of the set.
__
not closed example
The same set {0, 1} is not closed for addition:
0 +0 = 0
0 +1 = 1
1 +1 = 2 . . . not a member of the set
Performing addition on any two members of the set does not always give a member of the set.
_____
Additional comment
Sometimes you are asked to demonstrate closure of a particular set using a particular example. As we see with addition, above, some examples may seem to demonstrate closure, while another example may prove the set is not closed. In short, you can demonstrate that the set is closed for a particular operation on a particular example, but that does not demonstrate closure in general.

For this activity, you will need two coins.
First, you will determine the theoretical probability of events.
Then, you will flip the coins 100 times and determine the experimental probability of the events.
Flip two coins 100 times, and record the results of each coin toss in a table like the one below:
Result
Frequency
Two Heads
28
Two Tails
30
1 Head, 1 Tail
42
complete below
Answer the following questions based on the data you gathered. You must show your work to receive credit.
1. What is the theoretical probability that a coin toss results in two heads showing?
2. What is the experimental probability that a coin toss results in two heads showing?
3. What is the theoretical probability that a coin toss results in two tails showing?
4. What is the experimental probability that a coin toss results in two tails showing?
5. What is the theoretical probability that a coin toss results in one head and one tail showing?
6. What is the experimental probability that a coin toss results in one head and one tail showing?
7. Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
Answers
1. The theoretical probability that a coin toss results in two heads showing is 25% :
The probability of a head showing the first time is 50%
The probability of getting a head twice is 50% x 50% = 25%
2. The experimental probability that a coin toss results in two heads showing is 28/100 (28%)
3. The theoretical probablity that a coin toss results in two tails showing is 25% ( 50% x 50% )
4. The experimental probability that a coin toss results in two tails showing is 30/100 (30%)
5. The theoretical probability that a coin toss results in one head and one tail showing is 25% (also 50% x 50%)
6. The experimental probability that a coin toss results in one head and one tail showing is 42/100 (42%)
7. The theoretical probabilities have a difference from experimental probabilities because theoretical probabilities are equal odds of happening, while experimental probabilities might be biased because we might get tails for example, 10 times in a row, which messed up the odds.

Answer:
Question 1: C. 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333
Question 3: The volume fo the solid figure is 234
Step-by-step explanation:
1. Volume of a rectangular prism = (length × width × height) cubic units
Length = 4 × [tex]\frac{1}{8}[/tex]
Width = 3 × [tex]\frac{1}{8}[/tex]
Height = 2 × [tex]\frac{1}{8}[/tex]
Volume = 4 × [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex] × 2 × [tex]\frac{1}{8}[/tex]
Volume = 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
So the correct option is:
C. 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
2.
We have to fold the shape into a rectangular prism, look at the picture
Volume of a right rectangular prism = (length × width × height)
Length = [tex]\frac{1}{3}[/tex]
Width = [tex]\frac{1}{3}[/tex]
Height = [tex]\frac{3}{4}[/tex]
Volume = [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{3}{4}[/tex]
Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.
[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]
Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]
[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]
Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.
[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]
Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]
[tex]\frac{3}{36}[/tex]
Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3
Fraction form: [tex]\frac{1}{12}[/tex]
or
Decimal form: 0.083333333
So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]
3. Look at the picture with the solid figure labeled
We can think of this shape as two different prisms ( A and B)
Volume of A = 4.5 × 6 × 6.5 = 175.5
Volume of B = 3 × 3 × 6.5 = 58.5
Total volume of the whole figure = 175.5 + 58.5
175.5 + 58.5 = 234
So the volume of the solid figure is 234

A town has a population of 2000 and grows at 4. 5% every year. What will be the population after 13 years, to the nearest whole number?.
Answers
Answer:
3544 people
Step-by-step explanation:
We can start by representing this as an exponential function, in the form [tex]y=a(b)^x[/tex]
2000 will be our a, or our initial value. We must convert our multiplier, 4.5% to a decimal, which is 1.045. 13 is our input since it's our number of years where we want to find the population. Now that we have our variables, lets make an equation.
[tex]y=2000(1.045)^13[/tex]
PEMDAS states that we first do exponents, so lets raise 1.045 to the 13th power.
[tex]y=2000(1.77219609724)[/tex]
Now we multiply by 2000!
[tex]y= 3544.39219448[/tex]
Rounded to the nearest whole number is 3544. Therefore, there will be 3,544 people living in the town in 13 years.

The total number of marbles in Marcel's collection is 50.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Marcelo has 6 red marbles in his marble collection. Red marbles make up 12% of all the marbles.
The number of marbles in Marcel's collection is calculated as,
12% of marbles = 6
1% of marbles = 6 / 12
100% of the marbles= ( 6 / 12) x 100

Hii! Goodafternoon/morning!
Your question is asking how much is 3/8 + 3/8 + 3/8 is.
Normally, we would find a common denominator. But since they are all the same fraction, we don't need to.
First we need to figure out what 6×3 equals. That is 18.
We can't multiply 6×8.
So
We have to write the fraction has
18/8
But thats not simplified. So we need to turn this into a mixed number.
18/8 simplified is 2 2/8
We need to simplify that again.
2 2/8 simplified is 2 1/4.
So the answer is
2 and 1/4.

Step-by-step explanation:
Given;A music video got 390 views.The number of views that the video got each day increased by 30% per day.To Find;Total views did the video get over the course of the first 13 daysSo, For the first day the number of views is 390
Second Day
30% increased of total views
390 × 30 ÷ 100 = 11.7 = 12
390 + 12 = 402
Third Day
30% increased of total views
402 × 30 ÷ 100 = 120.6 = 121
402 + 121 = 523
Fourth Day
30% increased of total views
523 × 30 ÷ 100 = 156.9 = 157
523 + 157 = 680
Fifth Day
30% increased of total views
680 × 30 ÷ 100 = 204
680 + 204 = 884
Sixth Day
30% increased of total views
884 × 30 ÷ 100 = 265.2 = 265
884 + 265 = 1149
Seventh Day
30% increased of total views
1149 × 30 ÷ 100 = 344.7 = 345
1149 + 345 = 1494
Eight Day
30% increased of total views
1494 × 30 ÷ 100 = 448.2 = 448
1494 + 448 = 1942
Ninth Day
30% increased of total views
1942 × 30 ÷ 100 = 582.6 = 583
1942 + 583 = 2525
Tenth Day
30% increased of total views
2525 × 30 ÷ 100 = 757.5 = 758
2525 + 758 = 3283
Eleventh Day
30% increased of total views
3283 × 30 ÷ 100 = 984.9 = 985
3283 + 985 = 4268
Twelth Day
30% increased of total views
4268 × 30 ÷ 100 = 1280.4 = 1280
4268 + 1280 = 5548
Thirteenth Day
30% increased of total views
5548 × 30 ÷ 100 = 1664.4 = 1664
5548 + 1664 = 7212
Thus, Total views did the video get over the course of the first 13 days is 7212 Views.
