Suppose that the departmental final exam scores are normally distributed with a mean of 72 and a standard deviation of 9. Grades (A, B, C, D, F) are assigned according to the rule below. The top 10% receive an A.

The next 20% receive a B.

The middle 40% receive a C.

The next 20% receive a D.

The bottom 10% receive an F.

Find the lowest final exam score for a student to receive:
an A
a C
a D

correct answer:

i^31 = -i

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
