The answer is variable expenses.
Answer:

Step-by-step explanation:
GIVEN: A bag contain
red marbles,
green marbles and
blue marble. A marble is chosen at random from the bag and not replaced, then a second marble is chose.
TO FIND: What is the probability both marbles are green.
SOLUTION:
Total marbles in bag 
total number of green marbles 
Probability that first marble will be green 

Probability that second marble will be green 

As both events are disjoint
probability both marbles are green 

Hence the probability both marbles are green is 
Answer:
15 and a half days
Step-by-step explanation:
Since they earn $12's each day you would do $186 divided by $12 which would be 15.5 so it would take them 15 and a half days to raise $186.
Answer:
x = 20
Step-by-step explanation:
x/10 = 2 multiply both sides of the equation by ten ↓
10x x/10 = 10 x 2 reduce the numbers with the greatest common factor 10 ↓
x = 10 x 2 multiply the numbers ↓
x = 20
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55
