Answer:
The probabability is
Step-by-step explanation:
We are going to suppose that each score has the same probability.
For example :
Where P(66) is the probability of score a 66 and P(89) is the probability of score an 89
If A is a certain score :
In the exercise :
Bart must score higher than an 85 on the final exam.
We are looking for the probability of the event : ''Bart obtains a 1 or a 2 or ... or a 85''
This can be written in terms of events as :
P(1∪2∪...∪85) = P(1) + P(2) + ... + P(85)
As we consider each event as independent
If Lakita buys x boxes of water bottles, she will have y = 16x + 69 water bottles.
<span>
Lakita has enough money to buy only up to 5 boxes of water bottles, so she can buy 0, 1, 2, 3, 4, or 5 boxes of water bottles. These are the only reasonable values for the domain.
Substitute these values into the function rule to find the range values. </span>
Answer:
5n + 75 n = 160
Step-by-step explanation:
this is because nickels are worth 5 cents and quarters are worth 25 cents and the total value is 1.60. but since we have three times as many quarters as nickels so we do 5n + 75n = 1.60. But the problem with this is the right side of the equation is in terms of dollars while the left side is in terms of cents, so we convert both sides to cents and we get 5n + 75n = 160.(we could make both sides in terms of dollars, but that wasn't one of the options) hope this helps:)
