It would be just that. There is nothing to divide with the same number... If you need any more questions, just ask me.
Answer:
Option C, Ryder owed his mom $2.50. He babysits his sister and makes $8.75
Step-by-step explanation:
<em>Since it starts at 0 and goes to -2.5, that means that he owes $2.50</em>
<em>Since it goes from -2.5 to 6.25, that means that he ears $8.75</em>
Answer: Option C, Ryder owed his mom $2.50. He babysits his sister and makes $8.75
Procedure:
1) calculate the number of diferent teams of four members that can be formed (with the ten persons)
2) calculate the number of teams tha meet the specification (two girls and two boys)
3) Divide the positive events by the total number of events: this is the result of 2) by the result in 1)
Solution
1) the number of teams of four members that can be formed are:
10*9*8*7 / (4*3*2*1) = 210
2) Number of different teams with 2 boys and 2 girls = ways of chosing 2 boys * ways of chosing 2 girls
Ways of chosing 2 boys = 6*5/2 = 15
Ways of chosing 2 girls = 4*3/2 = 6
Number of different teams with 2 boys and 2 girls = 15 * 6 = 90
3) probability of choosing one of the 90 teams formed by 2 boys and 2 girls:
90/210 = 3/7

Hello!
----------
I think that 12/42=10/35 is a true proportion. 10/9=11/10 are almost a true proportion, but 10/9 is 1.1111111111..., and 11/10 is 1.1. 48/56=40/48 and 1/2=3/4 are different numbers when in decimal form.

I hope this helps and have a great day! :)
