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

Answer:
C. (f + g)(x) = 3x² + 3x/2 - 9
Step-by-step explanation:
(f + g)(x) requires you to add functions f(x) and g(x) together. Therefore:
(f + g)(x) = x/2 - 3 + 3x² + x - 6
Combine like terms:
(f + g)(x) = 3x² + x + x/2 - 3 - 6
Simplify:
(f + g)(x) = 3x² + 3x/2 - 9
Therefore, the correct answer is C.
Answer is b for sure I am just trying to get point not right answer decrees
number 3 is your answer x<-y+4/2-4
Answer:
Step-by-step explanation:
The picture does not show the example which will help in determining whether it is simple or compound interest calculation.
Based on what is shown, the answer is:
the numerator is: {(n + 11) + (n + 10) + (n + 9 ) + (n + 8) = 4n + 38;
and the denominator is: {(n) + (n + 1) + ... + (n + 11) = 12n + 66.
Therefore, the fraction is numerator/denominator:
= (4n + 38) / (12n + 66)
In this case n=1, the fraction = 42/78 = 0.53846
= 53.85%
