Answer:
His overal final score is 81.2. His letter grade is a B.
Step-by-step explanation:
Weighed average:
The sum of all values multiplied by it's weight. The weight is a proportion(a value between 0 and 1).
So.
Score of 72 on the midterm, which counts 5%.
Score of 83 on the project score, which counts 25%.
Score of 91 on homework assignments, which counts 35%.
Score of 74 on the final exam, which counts 35%.
His grade is:
G = 72*0.05 + 83*0.25 + 91*0.35 + 74*0.35 = 82.1.
His overal final score is 81.2.
At least 80 but less than 90 is a B
So his letter grade is a B.
2x+5y=8
5y=-2x+8
y=-2/5x+8/5. As a result, the y-intercept is 8/5 or 1 3/5. Hope it help!

Answer:
mean: 6
median: 6
Step-by-step explanation:
mean = sum of terms divided by number of terms
sum of terms = 11 + 2 + 10 + 3 + 9 + 1 + 6 = 42
number of terms = 7
42/7 = 6
mean = 6
median = the value separating the higher half from the lower half
first, you must organize the numbers from lowest to highest
1, 2, 3, 6, 9, 10, 11
from then, you find the number in the center
that number is 6
median = 6
hope this helps
