A group of 20 people are going to run a race. The top three runners earn gold, silver, and bronze medals. How many outcomes are possible for these awards?

Answers

Answer 1

Answer:

There are 6,840 possible outcomes for these awards.

Step-by-step explanation:

Given that a group of 20 people are going to run a race, and the top three runners earn gold, silver, and bronze medals, to determine how many outcomes are possible for these awards, the following calculation must be performed:

20 x 19 x 18 = X

380 x 18 = X

6.840 = X

Therefore, there are 6,840 possible outcomes for these awards.

Answer 2

Total outcomes that are possible for these awards are 6840 outcomes, calculated using permutation.

Total number of people=20

what is the difference between permutation and combination?

permutation means the arrangement of items while the combination is all about the selection of some out of many.

let us say start with the gold medal

no of ways a gold medal can be given = ²⁰C₁ = 20

Now, the number of people left is 19

no of ways a silver medal can be given = ¹⁹C₁ = 19

Now, the number of people left is 18

no of ways a bronze medal can be given = ¹⁸C₁ = 18

possibility of total outcomes=20*19*18 = 6840ways

Therefore, total outcomes that are possible for these awards=6840

I don’t know how to do this so please someone teach me how to do this?? I need help here!

Answers

Answer:

2.33

Step-by-step explanation:

imagine a circle. its center is A, and it goes through B, so its radius is AB.

then it is important to know that the sum of all the angles in a triangle is 180 degrees.

one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.

more back to our circle.

in this circle the line CB is the sine of the angle at A multiplied by the radius.

and AC is the cosine of the angle at A multiplied by the radius.

we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).

=> CB = sin(A)×AB

AC = cos(A)×AB

=> 5 = sin(65)×AB

=> AB = 5 / sin(65)

=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =

= 5 × cot(65) = 2.33

Since you need to find the side length AC, you already have a 25° angle plus the right angle which indicates it 90°. With that you add them up to get 115°. Since the total of the triangle is 180° you subtract that to get 65°. to check the answer you add the degrees all together to make sure you have a total of 180°. Let me know if you need more clarification

The other section called 1/2 can also be marked into three equal sections.

That will produce 6 smaller sections of the whole pizza.

Look at the one of the half of the pizza.

One of the three slices of 1/2 of the pizza is 1/3 of 1/2 of the pizza.

Trisha's favourite song is 2 1/2 minutes. There is a drum solo that begins one third of the way into the song and last for 24 seconds. How many seconds does the drum solo end

Answers

Answer:

74 seconds or1 minute 14 seconds

Step-by-step explanation:

The drum solo begins a third of the way into the song which lasts 2.5 minutes.

The drum solo therefore starts at:

= 2.5 * 1/3

= 0.83 minutes

Translate that to seconds by multiplying by 60:

= 0.83 * 60

= 50 seconds

Solo begins at 50 seconds in and lasts for 24 seconds:

= 50 + 24

= 74 seconds or

d=0.2+10Ld is equal to 0 point 2 plus 10 liters

d=10+0.2Ld is equal to 10 plus 0 point 2 liters

L=0.2+10dcap l is equal to 0 point 2 plus 10 d

L=10+0.2dcap l is equal to 10 plus 0 point 2 d

Answers

Answer:

L = 0.02d + 10

Step-by-step explanation:

The hair starts at 10 inches long.

L = 10

Now we add 0.02 inches in length per day.

In 1 day, it grows 0.02 inches.

In 2 days, it grows 0.02 * 2 inches.

In d days, it grows 0.02d inches.

Now we add the starting length, 10, and the growth per day, 0.02d, to get:

L = 0.02d + 10
