Answer:
E[T] = 10
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distribution has two bounds, a and b, and the expected value of the uniform distribution is given by:

Uniformly distributed between 0 and 20 minutes.
This means that 
Let T be the number of minutes you wait until you board a bus. Find E[T].
This is
![E[T] = \frac{a + b}{2} = \frac{0 + 20}{2} = 10](https://tex.z-dn.net/?f=E%5BT%5D%20%3D%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%20%3D%20%5Cfrac%7B0%20%2B%2020%7D%7B2%7D%20%3D%2010)
E[T] = 10
Answer:
The same number as in the multiplier
Step-by-step explanation:
The number of decimal places in the product is the sum of the decimal places in the factors.
A natural number is an integer. It has no decimal places.
So, the product has the product has the same number of decimal places as the multiplier.
For example, 2 × 3.45 = 6.90
The number 3.45 has two decimal places, so the product has two decimal places.
