Answer:
a) 0.2 L
b) 4800 ml
c) 2400 ml
Step-by-step explanation:
Total volume of water = 5 litres
Since 1000 milliliters make 1 L
5L = 5000 ml
a) litres of water spilt = 200/1000 = 0.2 L
b) milliliters of water remaining = 5000 - 200 = 4800 ml
c) since it was expressly stated in the question that the remaining water was divided evenly; 4800/2 = 2400 ml in each bowl
The student must score 94
98+96+94+88+94=470
470÷5=94 (average)

Question:</h2>
At Priscilla's school, the final grade for her Calculus course is weighted as follows: Tests: 50% Quizzes: 30% Homework: 20% Priscilla has an average of 87% on her tests, 100% on her quizzes, and 20% on her homework. What is Priscilla's weighted average?
<h2>
Work:</h2>
Weighted Average gives weights to each percent of the average as follows:
Weighted Average = Average * weighting percent
Weighted Average = Test Average * Test Weighting + Quiz Average. * Quiz Weighting + Homework Average * Homework Weighting
Weighted Average = 87% * 50% + 100% * 30% + 20% * 20%
Weighted Average = 43.5% + 30% + 4%
Weighted Average = 77.5%
<h2>
Answer:</h2>
