A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population after x years.

Answer:

f(x) = 300,000(1.05)^x

Step-by-step explanation:

Use the exponential growth equation:

f(x) = a(1 + r)^x

Plug in 300,000 as a, since it is the original population:

f(x) = 300,000(1 + r)^x

The city's population is growing at 5% each year, so plug in 0.05 as r:

f(x) = 300,000(1 + 0.05)^x

f(x) = 300,000(1.05)^x

So, the function for the population growth is f(x) = 300,000(1.05)^x

Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.

Is the probability of Janessa winning an independent event or dependent event? Why?

O) Her probability of winning is an independent event because it depends on the results of her friends’ rolls.

O) Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.

O) Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.

O) Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.

A certain psychological test measures empathy and emotional intelligence. The score, S, of a randomly selected senior student at a large university has a mean of 123 and a standard deviation of 29. The score, F, of a randomly selected first-year student at a large university has a mean of 104 and a standard deviation of 34.

Suppose we randomly select one senior student and one first-year student. We can consider S and F to be independent random variables.

Calculate the standard deviation of the difference D = S – F.
