Answer:
Constant of proportionality is y divided by x. y is 2 and x is 4. 2 divided by 4 is 1/2.
Let me know if that is correct.

so you have 1 in a 1000, or 1/1000. But you're missing a part of the answer. If you post the whole answer I can give you the correct answer :)
The answer to you question is B
Well, let us figure out what the first store will cost.
40*6.95=278
Now for the second store
325*0.8=260
So the first store is $278, while the second store is $260, so Elisa should buy shirts from the second store
Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
<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.
Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:
n = 4, p = 1/5 = 0.2.
The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:


0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
