Given:
The bag of apples is $6.33 for 3 pounds.
Required:
We need to find the unit rate of the cost of the apples.
Explanation:
Divide the cost of the bag of apples by the number of pounds.
Final answer:
The apples are $2.11 per pound
Answer:
The associative property of multiplication
Step-by-step explanation:
This property states that you can add or multiply regardless of how the numbers are grouped or how you use parenthesis. This means that if you are adding or multiplying, it doesn't matter where you put the parentheses.

Answer: The best deal is 1/2 a pizza for $8.
Step-by-step explanation:
-First you take all of the fractions, find the greatest common denomenator and make all of the denomenators the same
- I found that all the denomenators went into 30 so I multiplied them by what they needed to be 30
1/5 x 6 = 6/30 2/5 x 6 = 12/30 1/2 x 15 = 15/30 2/3 x 10 = 10/30
-By doing this you can see you get the most slices for $8
Answer:
a)
b)
for other case
c)
Step-by-step explanation:
We have a sample of iid uniform on the interval and we want to find the cumulative distribution function.
Part a
For this case we can define the CDF for , like this:
Part b
For this case we know that:
And since are independent we have:
And then we can find the density function calculating the derivate from the last expression and we got:
for other case
Part c
For this case we can find the mean with the following integral:
And after evaluate we got:
For the variance first we need to find the second moment like this:
And after evaluate we got:
And the variance is given by:
And if we replace we got:
And after do some algebra we got:
