19. DODECAHEDRON A dodecahedron has twelve sides numbered1 through 12. Find the probability and describe the likelihood
of each event.
a. Rolling a number less than 9
b.rolling a multiple of 3
c.rollinh a number grrater than 6​

Answers

Answer 1
Answer:

The probability of rolling a number less than 9 is P ( A ) = 2/3

The probability of rolling a multiple of 3 is P ( B ) = 1/3

The probability of rolling a number greater than 6 is P ( A ) = 1/2

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

a)

Rolling a number less than 9

There are 8 numbers less than 9 on the dodecahedron (1, 2, 3, 4, 5, 6, 7, and 8), out of a total of 12 numbers. So the probability of rolling a number less than 9 is:

P(rolling a number less than 9) = 8/12 = 2/3

The likelihood of rolling a number less than 9 is relatively high, as 2 out of every 3 rolls will result in a number less than 9.

Therefore , the probability is P ( A ) = 2/3

b)

Rolling a multiple of 3

There are 4 multiples of 3 on the dodecahedron (3, 6, 9, and 12), out of a total of 12 numbers. So the probability of rolling a multiple of 3 is:

P(rolling a multiple of 3) = 4/12 = 1/3

The likelihood of rolling a multiple of 3 is moderate, as only 1 out of every 3 rolls will result in a multiple of 3.

Therefore , the probability is P ( B ) = 1/3

c)

Rolling a number greater than 6

There are 6 numbers greater than 6 on the dodecahedron (7, 8, 9, 10, 11, and 12), out of a total of 12 numbers. So the probability of rolling a number greater than 6 is:

P(rolling a number greater than 6) = 6/12 = 1/2

The likelihood of rolling a number greater than 6 is relatively high, as 1 out of every 2 rolls will result in a number greater than 6.

Therefore , the probability is P ( C ) = 1/2

Hence , the probability is solved

Answer 2
Answer:

Answer:

a = 8/12 (2/3)

b = 4/12 (1/3)

c = 6/12 (1/2)

Step-by-step explanation:

a= 1-8 = 8 numbers less than 9

b= 3,6,9,12 = 4 numbers multiple of 3

c = 7-12 = 6 numbers higher than 7

How can I use number patterns to find the lcm of 120 and 360

Answers

You can use number patterns to find the LCM of 120 and 360 by multiplying 120 by 1,2,3,4,5,6,and so on and do the same with 360 until you find the least number that they have in common.

How to find area of square

Answers

To find the area of a square, remember that a square is a type of rectangle so we can use the following formula to find its area.

Area = length × width

However, since the length and width of a square are always equal, we use a special version of this formula to find the area of a square.

Instead of area = length × width, we say that the area of a square is equal to side × side or s².

I'll show an example.

Image provided.

Since each side of a square is the same, it can simply be the length of one side squared. So multiply the sides by one another say your square had a length of 10 and to find the area multiply the other side length since all squares mostly have the same side length multiply it by ten again and you get 100.

Is my answer right.

Answers

Answer:

Yes

Step-by-step explanation:

The two angles that are both acute (B and C in this case) add up to 90 degrees. That's because a right triangle has 1 angle that = 90 and every triangle has 180 degrees.

<B + <C + 90 = 180

<B + <C = 180 - 90

<B + <C = 90

Equation

2x + 15 + 5x - 2 = 90       Collect like terms

Solution

7x + 13 = 90                      Subtract 13 from both sides

7x = 90 - 13                       Subtract

7x = 77                               Divide by 7

x = 77/7                              Divide

x = 11                                  Substitute

<B

<B  = 2x + 15

<B = 2*11 + 15

<B = 37  which makes your answer right

B. Is correct


37°

BRAINLIEST ANSWER!!What is the median of the data represented by the box plot?



Enter your answer in the box.

Answers

The median is 20 because this is the middle vertical line of the box and whisker plot (aka box plot). The median line doesn't have to be in the direct center of the box. It just has to be between the edges of the box. The left edge is Q1 and the right edge is Q3. 

Answer: The answer is 20

Step-by-step explanation:

If you count all the numbers shown in the question: 0, 12.5 ,20 65 And 145.75

You have 5 numbers all together,

Tip: Look for the key word, such as the key word in this question is ''Median''

The word Median stands for ''The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.''

This means that the number 20 is the correct answer because, They are two numbers behind the number 20 being 0 and 12.5. And there's two numbers in front of the number 20 being 65 and 143.75
