Answer:
Barbara’s equation did not consider the number of bottles of iced tea.
Explanation:
She made this error because she included 1.25 with the x variable but did not include the x variable next to 1.49.
The x variable is important because it can keep track of how many bottles were sold of each water and tea.
So, this means <u>Barbara’s equation did not consider the number of bottles of iced tea.</u>
The real equations should be 1.25x + 1.49x = 100
Hope this Helps!
Using the binomial distribution, it is found that there is a:
- 0.0036 = 0.36% probability that both are allergic to pollen.
- 0.1164 = 11.64% probability that at least one is allergic to pollen.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Researching the problem on the internet, it is found that:
- 6% of the population is allergic to pollen, hence p = 0.06.
- Two people are chosen at random, hence n = 2.
The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.
0.1164 = 11.64% probability that at least one is allergic to pollen.

They are funded primarily through state taxes. Public colleges and universities rely on state and local government appropriations to subsidize the cost of education for students. State tax revenues are the primary source of nontuition funding, but local taxes accounted for more than 11 percent of total appropriations
