Answer:
Non representative
Step-by-step explanation:
A representative sample would be a subset of a population that accurately describes some characteristic from a larger group of people.
A sample of 40 patients from a local hospital is not a big enough sample to estimate the mean cholesterol level of U.S citizens (citizens from an entire country).
Therefore, this sample would be non representative.

Answer:
Partial-fraction decomposition is the process of starting with the simplified answer and taking it back apart, of "decomposing" the final expression into its initial polynomial fractions.
For example, Partial fraction decomposition is used to integrate rational functions and in engineering for finding inverse Laplace transforms.

Answer:
Length:
11
Width:5
Step-by-step explanation:
Let's say x is the width, then length is 3x-4
Area of a rectangle is Length times width
so x(3x-4)=55
then we solve
3x^2-4x-55=0
(3x+11)(x-5)=0
x cannot be negative so x=5
then if the width is 5, length is 3*5-4=11
