Question

A rock is thrown upward with a velocity of 25 meters per second from the top of a 49 meter high cliff, and it misses the cliff on the way back down. When will the rock be 8 meters from the ground level? Round your answer to two decimal places

Answer 1

It would take 5.81 seconds for the rock to be 10 meters from ground level

Explanation:

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

BlueSky Air has the best on-time arrival rate with 80% of its flights arriving on time.

This means that 100 - 80 = 20% are late, which means that

Randomly selecting 16 BlueSky Air flights

This means that

What is the probability that 2 flights of BlueSky Air arrive late?

This is P(X = 2).

0.211 = 21.1% probability that 2 flights of BlueSky Air arrive late
