To determine if these line segments are congruent you can find the distances between the x values and the y values for each set of points.
(-1, 10) and (-5, 2). 4 on x axis and 8 on the y axis.
(9, -7) and (1, -3). 8 on the x axis and 4 on the y-axis.
This means they are congruent. Each triangle would have the same two side lengths making the hypotenuse the same.
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
