Answer:

Step-by-step explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

$C=2\pi r$

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

$C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4$

So, it turned 785.4 feet with 1 rotation.

The correct answer is A

A bandleader randomly select's two students out of 100 bandmembers if you and your brother are both bandmembers what is the prob

kherson [118]

There are 100 * 99 = 9900 different ways to choose two students out of 100 bandmembers. You and our brother are 2 of that ways: you being selected first and you being selected second. Therefore the probability that you two are selected is 2 / 9900 = 0,000202. You can also think as the probability of you being selected among 100 bandmembers, which is 1/100, times the probability of your brother being selected among 99 members, which is 1/99 => (1/100) * (1/99) = 1/ (100*99) = 1 / 9900; plus the same for your brother being selected first and you second => [1/9900] * 2 = 2/9900, which is the same calculated above.
