John jones has decided to go into the business of producing and selling boats. in order to begin the venture, he must invest $10 million in a boat production plant. the cost to produce each boat will be $7000, and the selling price will be $20000. accounting for the cost of the production plant, create an expression which represents the profit, in dollars, that john will realize when x boats are produced and sold.

P(x) = 13,000x - 10,000,000

John's cost is the sum of fixed costs ($10,000,000) and variable costs ($7000·x).

John's revenue is the amount he gets from selling boats ($20,000·x).

The profit John realizes is the difference between revenue and cost:

... P(x) = revenue - cost

... P(x) = 20,000x -(10,000,000 +7000x) . . . . . use the expressions for each

... P(x) = 13,000x -10,000,000 . . . . . . . . . . . . . simplify

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
