Answer:
His overall final score is 81.5
He earned a B
Step-by-step explanation:
To find his overall grade, we multiply each of his grades by it's weight.
Grades:
67 on the midterm, which counts for 10% = 0.1
88 on the project, which counts for 15% = 0.15
91 on homework assignements, which counts for 40% = 0.4
72 on the final exam, which counts for 35% = 0.35.
What is his overall final score?
67*0.1 + 88*0.15 + 91*0.4 + 72*0.35 = 81.5
His overall final score is 81.5
At least 80 and less than 90 has a letter grade of B. 81.5 is in this range. So he earned a B
Answer:
5x + 4y - 20 = 0
Step-by-step explanation:
1. Find the two points given: (0,5) and (4,0)
2. Find the slope of the line:
m = 
3. Find y intercept by plugging in one point into the y-intercept form
y = (-5/4) x + b
0 = (-5/4) (4) + b
b = 5
4. Write out the equation in y-intercept form
y = (-5/4) x + 5
5. Rewrite it in Ax + By + C = 0 form
(5/4) x + y - 5 = 0
6. Since A B C all need to be integers, multiply the whole equation by 4
5x + 4y - 20 = 0
