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>
77.5%

I think it would 80/100 because £1 is 100 and we trying to work out the fraction of 80p of £1. So it would be 80/100. Hope this helps.
Answer:
3/8
Step-by-step explanation:
This is simple probability and we have to divided the possible outcomes by total outcomes.
The sample space is given by 2 raises to power n where n is the number of tosses .
Here we have 5 tosses .
The Sample Space is 2⁵.
The possible arrangement of three tails would be 3!
The possible ways of arranging 2 Heads would be 2!
We want to find the probability of 3 tails and 2 heads
Therefore
P (3 tails and 2 heads ) = 3! 2!/ 2⁵
=2* 6/ 2⁵= 12/32= 6/16= 3/8
Answer: The answer is D

Answer:
4) -11.3...
Step-by-step explanation:
distribute both sides to get (1/6)x - (4/3) = (4/15)x - (1/5)
move the variables to one side and the constants to the other: ((4/15) - (1/6))x = (-(4/3) + (1/5))
simplify to get (1/10)x = (-17/15) multiply everything by 10 to get x=-34/3 or -11.33333333333333333...
