Answer:
16 bottles
Step-by-step explanation:
you can buy 16 bottles
The store offers 10 type/color combinations. But, it can be 25 if you want to be technical .
Here is your answer
1. (−2^2 − 4 + 13) + (12^2 + 2 − 25)
= (4-4+13)+ (144+2-25)
[Note:- -2^2=(-2×-2)= +4]
= 13+ (146-25)
=13+121
= 134
2. (7^2 + 4 − 26) − (−7^2 − 3 + 15)
= (49+4-26) - (49-3+15)
= 49 +4 -26 -49 +3 -15
= 7-41
= -34

Answer: A. 6.5
Step-by-step explanation:
Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}
Mean, 
Number of elements, n = 8

Thus, the standard deviation, 
⇒ Option A is correct.
Let's suppose we want to solve

with

. Separating variables and integrating, we get

Leaving the solution in this form, the initial condition gives

This means the solution is

.
Now if we were to write

, then we would have found

so that the solution would have been

.
But these two solutions are the same, since

. So we get the same solution regardless of where we place

, despite getting different values for

.
