It’s simple, do: 8+8+10+10, just add them you will get 36. The explanation is: Perimeter is add up all the sides, since it is a rectangle it has congruent sides, so they have the same length
If the number of samples is increased, this actually leads
to a reduction in error of the distribution. This is because of the
relationship between variation and sample size which has the formula of:
σx = σ / sqrt (n)
So from the formula we can actually see that the variation
and sample size is inversely proportional.
Which means that increasing the sample size results in a
reduction of variation.
Answer:
It will have less variation
Almost; she's just missing 1, since 1*88 = 88.

Answer:
(D) 9/5
Step-by-step explanation:
One way to work this problem is to find % per cup for cereal and cups per % for milk, then multiply the product of those by 2.
The way we'll use here is to find the ratio of cups of milk to cups of cereal for the same % RDA.
We're given an amount of milk that has 25% of the RDA, but we want to find an amount that has 15% RDA. That amount of milk will be ...
(15%)/(25%)(1 cup milk) = 3/5 cup milk
This tells us that 3/5 cup milk has the same %RDA as 2/3 cup cereal. That ratio is ...
milk/cereal = (3/5)/(2/3) = (3/5)(3/2) = 9/10 cup of milk per cup of cereal
Then for 2 cups of cereal, we need ...
(9/10)(2 cups cereal) = 9/5 cups milk . . . . matches choice D
