second-period class average:
55+70+450+480+170+270+95 = 1590
1590/20 = 79.5
sixth-period class average:
65+225+480+595+270+190 = 1825
1825/20 = 91.25
on average, students in the sixth period class scored higher
0.00009 might help I’m not sure about the possible answers but that one seems reasonable
Answer:
243/506
Step-by-step explanation:
There are 24 total juice boxes.
18 of them are not grape
You have an 18/24 chance of picking not grape juice
The second time, 1 is removed, then another is removed. This creates:
(18/24)*(18/23)*(18/22) = 243/506
Here, you would complete it with the Pythagorean Theorem.
So, A^2 + B^2 = C^2
So 14^2 + B^2 = 14^2
This equals = B = 11.49
