The answer is 352,716.

This is a combination; out of 21 you are choosing 10:

Answer:

352,716 juries of 10 people can be formed from 21 possible candidates

Step-by-step explanation:

I am supposing that there are no roles in the jury, which means that the order in which the people are chosen is not important. So i calculate the number of possible juries using the combinations formula.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

10 people from a set of 21

C_{21,10} = \frac{21!}{10!(21-10)!} = 352,716

352,716 10 person juries can be formed from 21 possible candidates

If Usain Bolt can run a marathon (26.2) in 2 hours and 15 minutes, how fast would he run if he ran at the same constant rate?
inn [45]

Answer:

The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon.

Step-by-step explanation:

Given as :

The Distance of marathon = 26.2 unit

The time taken to complete marathon = 2 hours and 15 minutes

                                                                = 120 + 15 = 135 minutes

Let The constant speed of Usain Bolt = S unit per minutes

So, Speed = \frac{Distance }{Time}

Or, S  = \frac{26.2 }{135}

∴   S = 0.194  unit per minutes

Hence The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon.   Answer
