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:
So, we have:
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:
30,60,90
Step-by-step explanation:
A triangle’s interior angles sum to 180.
1:2:3 ratio
180 divided by 6 (add up the ratio numbers)= 30. Use 30 in the ratios.
(30x1=30, 30x2=60, 30x3=90)
30,60,90
30+60+90=180 (add back up to make sure they sum to 180 to check your answer)
Answer:middle angle = 5 * the smallest. sum of the angles of a triangle is 180. let x = the size of the smallest angle. the size of the ...

Answer:
- 1
Step-by-step explanation:
f(x) + g(x) = - 2x² + 1 + 3x = - 2x² + 3x + 1
Substitute x = 2 into the expression for f(x) + g(x)
= - 2(2)² + 3(2) + 1 = - 8 + 6 + 1 = - 1
