Step-by-step explanation:-
Given : In an exam , Mean score :
Standard deviation :
Let X be a random variable that represents the scores of students.
We assume that the points are normally distributed.
Z-score :
For x = 85, we have
Then using standard normal distribution table, the probability that the students received more than 85 is given by :-
Hence, the percentage of students received more than 85 =12%
2/25 because since there are 2 #'s after the decimal you know that the denominator in 100. find the common factor which in this case is 4 and divide both the numerator and denominator by the common factor to simplify
P(t) = 5,000 (1-r)t
P(t) = 5,000 (1-7%)t
P(t) = 5,000 (0.93)t
