APR = Annual Percentage Rate; APY = Annual Percentage Yield.
This is a tough question!!

To get the APY we use the compounding formula (A = P(1+r/n)^nt) and put $1 in for the principal and see what our final amount is at 19.07% after a year.

A = 1(1+.1907/12)^12

A= 1.0159^12

A= 1.2083  This means that we paid 0.2083 on our dollar after a year which means the APY is 20.83%.

Answer:

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

P(X \leq x) = \frac{x - a}{b-a}

Uniform distribution from 0 to 4.8 seconds.

This means that a = 0, b = 4.8

61% of the time a person will wait at least how long before the wave crashes in?

This is the 100 - 61 = 39% percentile, which is x for which P(X \leq x) = 0.39. So

P(X \leq x) = \frac{x - a}{b-a}

0.39 = \frac{x - 0}{4.8 - 0}

x = 4.8*0.39

x = 1.872

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
