Given the answers of 100 students surveyed, you have to find the following probability:
<em>P(taken a public speaking class | majoring in business administration)</em>
This is the probability that the student has taken a public speaking class, given that he is majoring in business administration, which is a conditional probability.
We already know that the student is majoring in business administration, so instead of working with the information about the 100 students, you can directly work with the group os students that are doing that major:
You can determine this probability as the quotient between the students that took a public speaking class and are majoring in business and the total number of students that are majoring in business:
So, the probability is 10/55
20 25 30 35 40 45 50 55 60 65 70 75 80

Answer:
NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season
Answer: 8 vests
Step-by-step explanation:
Mrs Chapman used 3/4 yards of martial for 1 vest.
When she used 6 yards, we are told to calculate the number of vest she made.
3/4 yards = 1vest
6 yards = y
We represent the number of vest made with y.
(3/4) / 6 = 1 / y
0.75/6 = 1/y
Cross multiply
0.75y = 6
Divide both side by 0.75
0.75y/0.75 = 6/0.75
y = 8
She will make 8 vests from 6 yards.
