Suppose that a college student is taking three courses: a two-credit course, a three-credit course, and a four-credit course. The expected grade in the two-credit course is 3.5, while the expected grade in the three- and four-credit courses is 3.0.

What is the expected overall grade point average for the semester? (Remember that each course grade is weighted by its share of the total number of units.)

Given Information:

Grade in two-credit course = 3.5

Grade in three-credit course = 3.0

Grade in four-credit course = 3.0

Required Information:

Expected GPA = ?

Expected GPA = 3.11

Step-by-step explanation:

The overall expected GPA is basically the mean or average

E(X) = μ = Sum of grades/Total credit hours

Sum of grades = ∑ weight*grade

Sum of grades = 2*3.50 + 3*3.0 + 4*3.0 = 28

Total credit hours = 2 + 3 + 4 = 9

E(X) = μ = Sum of grades/Total credit hours

E(X) = μ = 28/9

E(X) = μ = 3.11

Therefore, the expected overall grade point average of this student for the current semester is 3.11

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
