Total number of 10 grader students = 260 students.
Total number of students who rides the bus and they are of 10th grader = 150 students.
Probability (a student rides the bus given that they are a 10th grader) =![\frac{Total \ number \ of \ students \ rides \ the \ bus \ and \ 10th \ grader}{Total \ number \ of \ 10 \ grader \ students}](https://tex.z-dn.net/?f=%5Cfrac%7BTotal%20%5C%20number%20%5C%20of%20%5C%20students%20%5C%20rides%20%5C%20the%20%5C%20bus%20%5C%20and%20%5C%2010th%20%5C%20grader%7D%7BTotal%20%5C%20number%20%5C%20of%20%5C%2010%20%5C%20grader%20%5C%20students%7D)
Therefore,
P(E) = ![\frac{150}{260}](https://tex.z-dn.net/?f=%5Cfrac%7B150%7D%7B260%7D)
Dividing top and bottom by 10, we get
P(E) = 15/26.
In decimals 0.577.
Therrefore, correct option is C) 150/260 = 15/26 = .577.
Answer: 3 meters downward per second
Step-by-step explanation:
If it moved downward 15 meters for every 5 seconds and to find the change in the elevation each second then divide the meters by 5.
15/5 = 3
3 meters per second

i did not get it what question?
Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A). As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.
B). Probability of at least one germinating = 1 - probability that none germinate
Probability of 1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.
