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

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 ,

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

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

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:

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

The ratios a:b and b:c are equivalent to one anotherSelect all the statements that must be true

1. a=c

2. $(b)/(a) = (c)/(b)$

3. b-a=c-b

4. a
5. if a=b, then b=c

I think #2 is correct ,but I don't know about the others

Answers

Options 2 and 5 i.e., $(b)/(a)=(c)/(b)$ and $b=c$ are the correct statements such that $(a)/(b)=(b)/(c)$ .

Ratio

Ratio is the mathematical indication that tells how many times one number contains another.

How to simplify the ratios?

Reciprocate the given proportion both sides-

$(b)/(a)=(c)/(b)$

So, option 2 is correct.

Now, if $a=b$ then, the proportion will become-

$1=(b)/(c)\nb=c$

So, option 5 is correct.

Thus, options 2 and 5 are the correct statements.

a : b
b : c

Imagine if the ratio is as follows :
3 : 6
6 : 12

Yes, only number 2 is correct.

Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.

So yes, only number 2 is correct.

4x-2=90 wha is the answer to this problem?

Answers

Firstly, you want to get 4x alone, so to do this, you add 2 to both sides, as you always do the opposite operation.
This then becomes
4x=92
To get x alone, you then divide both sides by 4.
92/4=23
Therefore, x= 23
Hope this helps :)

Your goal is to get "x" by itself on one side

$4x-2=90$

Add +2 to each side

$4x-2+2=90+2$

$4x=92$

Divide 92 by 4

92÷4=23

$x=23$

You place a mirror on the ground 6 feet from the lamppost. You move back 3 feet and see the top of the lamppost in the mirror. If you are 5 feet tall, what is the height of the lamppost?

Answers

Setting up a proportional relationship between mirror and lamppost, the height of the lamppost is 10 feets.

Height of person, Hp = 5 feets

Distance of person form mirror, Dp = 3 feets

Distance of Lampost from mirror, Dm = 6 feets

HeightofLampost=Hl=?

Setting up a proportional relationship :

$(Hp)/(Dp) = (Hl)/(Dm)$

$(5)/(3) = (Hl)/(6)$

Cross multiply :

Hl × 3 = 6 × 5

3Hl = 30

Hl = (30 ÷ 3)

Hl = 10

Therefore, the height of the lamppost is 10 feets.

Answer: 10 feet

Step-by-step explanation:

Let h be the height of lamppost.

Since both the person and the lamppost are standing vertical to the ground, making similar right triangles.

Because the two triangles are similar, the ratio of their sides is the same.

Therefore, we have

$\frac{\text{height of lamppost}}{\text{distance of lampost from mirror}}=\frac{\text{height of person}}{\text{distance of person from mirror}}\n\n\Rightarrow(h)/(6)=(5)/(3)\n\n\Rightarrow\ h=(6*5)/(3)\n\n\Rightarrow\ h=10$

Hence, the height of the lamppost = 10 feet.
