Answer:
The standard deviation for the probability distribution is of 2.63 houses sold.
Step-by-step explanation:
To find the standard deviation for the distribution, first we have to find the mean.
Mean:
Each outcome multiplied by it's probability. So
Standard deviation:
Square root of the sum of the differences squared between each value and the mean, multiplied by its probabilities. So
The standard deviation for the probability distribution is of 2.63 houses sold.

Answer:
4e²
Step-by-step explanation:
Using the rule of exponents
=
Given
= ×
= 4 ×
= 4e²
If , then
which is of course divisible by 6.
Assume the claim holds for . Then if , we have
(I use the distributive property of multiplication to extract the first term, which we've assumed is divisible by 6)
The claim holds for if
is also divisible by 6. With some manipulation we can express this as
which is clearly divisible by 6, so the claim is true for , and this completes the proof (by induction).
