How many points are there total? (3*100)+250 = 550
So far, he has 72 + 85 + 78, or 235
He needs 0.80 * 550 for a B, or 440 points
440 - 235 = 205 points on the final to get a B
Percentage-wise, he needs 205/250, or 0.82
500 milliliters because 1 liter=1000 milliliters
Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13
