Answer
A
Step-by-step explanation:
First, lets go through B-D and explain why they are correct.
B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.
C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.
D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.
A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.
Hope this helps!
Answer:
There is a 50.18% probability that they are of the same gender.
Step-by-step explanation:
We have these following percentages:
53% of the students are males.
47% of the students are females.
If two students from this college are selected at random, what is the probability that they are of the same gender?
The probability that each is male is 53%. So the probability of both being males is
The probability that each is female is 47%. So the probability of both being females is
The probabilty that both are the same gender is:
There is a 50.18% probability that they are of the same gender.
