Answer:
The ratio of the income in 2003 would be $54,300.
Step-by-step explanation:
Given that the yearly income for an individual with an associate degree in 2001 was $53,166 and 2013 was $59,970, we can determine that in 12 years there was a wage increase of $ 6,804 (59,970 - 53,166). Thus, on average, each year there was a salary increase of $ 567 (6,804 / 12). Therefore, given that in 2003 two years had passed since the starting value of $ 53,166, following this reasoning and without inflationary or recessionary changes, this person's salary should have been $ 54,300 (53,166 + 567 x 2).
The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%

Answer:
96 ways
Step-by-step explanation:
Let´s call flags of countries from Africa as A₁, A₂, A₃, A₄, and from Europe as E₁, E₂, E₃ and E₄
We have to display the flags always beginning with one flag from Africa let´s take A₁
For that flag, we have 4! possibilities Then 4! is:
4*3*2*1 = 24
As we have 4 different Flags from Africa, we will have
4*24 = 96 possibilities
Answer:
The standard deviation of the sample mean is 4 minutes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
The standard deviation of the population is 32.
Sample of 64.
So
The standard deviation of the sample mean is 4 minutes
