1/10 because 1/2 =5/10 and 2/5=4/10 and 5/10+4/10=9/10 and then 10/10-9/10=1/10
2 out of 8 because the chances of two plants not growing is 2 out of 8 plants in total
If its (1/5)^4
625-3x=625
-3x=0
x=0
If its 1/5^4 then the answer is 390624/1975
I'm betting its (1/5)^4
Order of operations matters
Answer:
The Alans's average for the course is 84.5
Step-by-step explanation:
We are given
There are 4 tests, A Term paper and a Final examination.
Score = 92, 78, 82, 90.
Term paper score = 80
Final examination score = 86
Weighted mean = ∑ w.f/∑w
also the sum of all the weights is 100% = 1
weighted mean = 15%*92 + 15%*78+15%*82+15%*90+20%*80+20%*86/1
= 51.3 + 33.2
= 84.5
Therefore the Alans's average for the course is 84.5
