Answer:
Simple, no. This would not be enough.
Step-by-step explanation:
This is because you mentioned that there are 20 students and each of them needed 2 plates. So, there would need to be at least 40 plates. Forks seem irrelevant in this question but if the teacher has 8 plates in 1 box and another 8 in the second box, that would sum up to 16 plates that are available. And the fact that the box doesn't even include the other items, should hint the lack of items available for the students.
This question seemed worded differently. But tried my best. :)
Answer:
4 or -625x^4 (Just in case I misunderstood)
Step-by-step explanation:
The degree is always the power of something. Since -5x has a power of 4, its degree is 4.
Just in case I misunderstood the question, I will solve it another way that I think you meant. (-5x)^4 is -5^4 times x^4.
-625 times x^4 is -625x^4.
A) n(a) = 25 + 15 = 40
b) n(b) = 42+15 =57
c) n (a U b) = 25 +15+ 42 = 82
d) n (a') = 42
e) n(b') = 25
f) n(a intersection b)' = 82-15 = 67
g) n (a U b)' = 14
h) n (a' intersection b') = 14
i) n (a' U b') = 42 + 25 +14 = 81
hope i helped a bit .. :-)
Nathan ate 20/24, Leroy ate 21/24, and Sofia ate 15/24 meaning Leroy ate the most
Solution:
As, Mean = 
Standard deviation is a number which describes or depicts relationship between mean and the number(Called Standard deviation).
So , if the difference between mean and standard deviation is large then it means data is widely spread i.e farther from mean and if Difference between mean and standard deviation is small it means data are close to mean.
So,in the given question , it is study about a group not individual players, so instead of studying mean , that gives average , if he will calculate standard deviation that is the number of points earned by each group,which will describe performance of each player as well as average of the group, that will give better description about the two groups.
Option (C) The standard deviation of the number of points earned by each group, is true statement about the study of two groups given in this question.
