Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as 
then the equation relating them is
w = 
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w = 4 × 
= 4 × 2 = 8
w = 
← equation of variation
When x = 25, then
w = 
= 
= 1.6
1/16 * 6 = 6/16 or reduced to 3/8
No idea what this is, sorry
The answer is a the more balls means the more chance a desired color will be chosen
You simply divide 3 into 8, which results in 0.375. Now you add 7 to it, which is 7.375.
