The probability of a student taking the bus given that the student is a sophomore is 0.83
The complete question is attached with the answer below:-
<h3 /><h3>What is probability?</h3>
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:
- P(Walk to school | Sophomore) = 3 /(2 + 25 + 3) = 0.1
- To calculate the probability of a student taking the bus given that the student is a sophomore, we make use of:
- P(Take the bus | Sophomore ) = 25/(2 + 25 + 3)
Rewrite properly as:
![P_r = \dfrac{25}{3+2+25}](https://tex.z-dn.net/?f=P_r%20%3D%20%5Cdfrac%7B25%7D%7B3%2B2%2B25%7D)
So, we have:
![P_r = \dfrac{25}{30}](https://tex.z-dn.net/?f=P_r%20%3D%20%5Cdfrac%7B25%7D%7B30%7D)
Divide 25 by 30
Pr = 0.83
Hence, the probability of a student taking the bus given that the student is a sophomore is 0.83

Answer:
add'em all up
Step-by-step explanation:
Answer: b. y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
time spent on history homework: 20 minutes
time spent on each math problem: 2 minutes
math problem : x
total time spent :y
So, we have to multiply each math problem (x) by the time spent on each math problem and add the 20 minutes spent on history homework.
The expression obtained is equal to the total time spent
Mathematically speaking:
y=2x+20
x can be any real number greater than or equal to 0, ( it would be 0 if there aren't any math problems)
and y is any real number greater than or equal to 20. ( 20 minutes is the minimum time spent if there aren't any math problems)
Alright, lets get started.
The quantity of the shampoo Jill always buys = 11.5 ounce
She is at the store buying more and sees that the bottle is now bigger and has 20% more for the same price.
Means we could find the extra shampoo she is getting by :
![\frac{20}{100} * 11.5](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B100%7D%20%2A%2011.5%20)
ounce
Means she is getting total shampoo in her new bottle = ![11.5 + 2.3](https://tex.z-dn.net/?f=%2011.5%20%2B%202.3%20)
Means she is getting total shampoo in her new bottle = 13.8 ounce : Answer
Hope it will help :)
