The distribution of jamal's high school grades by percentage of course credits is A=70%; b=20%; c=10%. What is jamal's grade point average if each a is worth 4 points; each b is worth 3 points; and each c is worth 2 points?
Well, let's do some math, shall we? First, let's convert the percentage of course credits to points. An A is worth 4 points, a B is worth 3 points, and a C is worth 2 points.
So, if 70% of Jamal's grades are A's, that means he gets 70% * 4 = 2.8 points for the A's.
Similarly, 20% of his grades are B's, so that's 20% * 3 = 0.6 points for the B's.
Lastly, 10% of his grades are C's, which gives us 10% * 2 = 0.2 points for the C's.
Now, let's add up all the points Jamal earned: 2.8 + 0.6 + 0.2 = 3.6 points.
Since we know Jamal earned a total of 100% of the course credits, his grade point average would be 3.6 points.
So, Jamal's grade point average is a straight-up 3.6. Keep up the good work, Jamal! Just don't let those clowns distract you! 🤡
To calculate Jamal's grade point average, we need to assign points to each grade and then calculate the average.
First, let's convert each grade to points:
- A=70% (4 points) = 0.70 * 4 = 2.80 points
- B=20% (3 points) = 0.20 * 3 = 0.60 points
- C=10% (2 points) = 0.10 * 2 = 0.20 points
Next, let's calculate the weighted average by multiplying each grade's points by its corresponding percentage of credits and summing them up:
(2.80 * 0.70) + (0.60 * 0.20) + (0.20 * 0.10) = 1.96 + 0.12 + 0.02 = 2.10 points
Therefore, Jamal's grade point average is 2.10.
To calculate Jamal's grade point average (GPA), we need to multiply the percentage of each grade by the corresponding point value and sum up the results.
First, let's convert the percentages to decimals:
A = 70% = 0.70
B = 20% = 0.20
C = 10% = 0.10
Next, let's assign the point values to each grade:
A = 4 points
B = 3 points
C = 2 points
Now we can calculate the weighted GPA:
GPA = (A * A weight) + (B * B weight) + (C * C weight)
GPA = (4 * 0.70) + (3 * 0.20) + (2 * 0.10)
Calculating the values:
GPA = 2.80 + 0.60 + 0.20
Adding them up gives:
GPA = 3.60
Therefore, Jamal's grade point average is 3.60.
