Answer: P = 0.75
Step-by-step explanation:
Hi!
The sample space of this problems is the set of all the possible sales. It is divided in the disjoint sets:
We have also the set of sales of boat accesories 
, the colored one in the image.
We are given the data:
From these relations you can compute the probabilities of the intersections colored in the image:
You are asked about the conditional probability:
To calculate this, you need 
. In the image you can see that the set is the union of the two disjoint pink and blue sets. Then:
Finally:
500=2.5x+200
x=the amount of desserts.
500-200=2.5x
300=2.5x
x=120
C is the answer.
So the first 20 boxes at 4.45 a piece will total 89.
The next 25 at 4 each will be 100.
Add those and you have 189 dollars, which is a spare of 45.
45/3.75 = 12 .
So the answer is 57
Answer: -5x + 2y -9 = 0
Step-by-step explanation:
1. Move constant to the left and change its sign
2. Change the signs on both sides of the equation
Answer:
