7(a^2+b)-4(a^2+b)
7(a^2)+7b-4(a^2)-4b
7a^2-4a^2+7b-4b
(7-4)a^2+(7-4)b
3a^2+3b

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:
Answer:
Quotient = 5.67 (Approx)
Step-by-step explanation:
Given:
Dividend = 68.0052
Divisor = 12
Find:
Quotient
Computation:
Quotient = 68.0052 / 12
Quotient = 5.6671
Quotient = 5.67 (Approx)
