Answer:

Correct option: C (it is missing the point)

0.53

Step-by-step explanation:

When a ball rolls one revolution, the distance travelled is the length of its circunference, that is:

Circunference = pi * diameter

So, to solve this question, we can use a rule of three:

1 revolution -> pi * d

60 revolutions -> 100 feet

100 = 60 * pi * d

d = 100 / (60 * pi) =  0.53 feet

Correct option: C (it is missing the point).

Two married couples have purchased theater tickets and are seated in a row consisting of just 4 seats. If they take their seats
Licemer1 [7]

Answer:

The answer is 0.75.

Step-by-step explanation:

To use probability of a complement event, we need to find the situation where none of the couples are sitting next to each other which can happen either two husbands are sitting in the seats 2 and 3 or two wives are sitting in the seats 2 and 3. Also in the first scenario, the wives would need to be sitting at the opposite ends to their husbands and vice versa for the second scenario.

So there are in total 4 scenarios where no couple is sitting next to each other.

There are a total of 16 different ways that they can be seated so the probability of compelement is 16 - 4 = 12, which is 3/4 of the total, meaning that the probability of at least one of the wives sittting next to her husband is 0.75 or 75%.

I hope this answer helps.
