In y=mx +b?
If so then -3=-2(3)+b
B=3
X=-4 is the answer because all of the points of the line are x=-4
In this question, both tickets cost 2$ per ticket.
The answer to this question would be: $0
In WinOne scenario, you need to match a ticket that has to pick from A-J(10 possibilities) and 0-9 (10 possibilities). The chance to win would be: 1/10* 1/10= 1/100
The expected value must be:
E= chance to win * win amount - ticket price
E= 1//100*$200 - $2= $2-$2= 0
Answer: Choice A) {-4, -1, 3, 5, 6}
The domain of a relation is the set of possible x inputs. All we do is list the x coordinates of the given points. The order doesn't matter but your book has decided to list the x values from smallest to largest.
Side note: the list of possible output y values is known as the range.
The answers should be 1D, 2C, 3B, 4A, and 5A.
