Answer:
x = 9
Step-by-step explanation:
Corresponding segments are proportional, so ...
(2x -8)/5 = (x -3)/3
3(2x -8) = 5(x -3) . . . multiply by 15
6x -24 = 5x -15 . . . . eliminate parentheses
x = 9 . . . . . . add 24-5x
There are 4+6=10 people in the team.
First calculate in how many ways you can choose 3 people from a group of 10 people, using combination:
You can choose 3 people in 120 ways.
You can select 1 girl from a group of 4 girls in 4 ways.
Calculate in how many ways you can choose 2 boys from a group of 6 boys:
You can choose 2 boys in 15 ways.
Using the rule of product, you can calculate that you can choose 1 girl and 2 boys in 4×15=60 ways.
The probability of choosing 1 girl and 2 boys is the number of ways you can choose 1 girl and 2 boys divided by the number of ways you can choose 3 people from the group.
The probability is 1/2, or 50%.
