5. Arrival problems usually follow a Poisson distribution, but in this case the time between arrivals of customers at a bank dur

Finger [1]

Answer:

0.5 or 50%

Step-by-step explanation:

For any given value of 'x' representing the time between arrivals of two customers. If 0 < x <120, then the cumulative distribution function is:

$\frac{x-0}{120-0}=\frac{x}{120}$

Therefore, the probability that the time between the arrivals of two customers will be more than 60 seconds is determined by:

$P(X>60) = 1 -\frac{60}{120}\\P(X>60) = 0.5$

The probability is 0.5 or 50%.

Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue

Nadya [2.5K]

Answer:

There were 36 space rocks in total.

Step-by-step explanation:

First, you need to find what fraction of the original rocks are silver.

If 2/3 are purple, then 1/3 of them are not.

If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.

2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.

So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.

This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.

So:

1/12r = 3

r = 36 silver rocks

There were 36 space rocks in total.

hope this helps :)

Rewrite in simplest radical form 1 over x^(−3/6). Show each step of your process.
