1. hypothesis- (if you eat properly and exercise regularly)

conclusion- (then, you will have good health)

2. hypothesis- (if a and b are positive integers)

conclusion- (then, their product is positive.)

3. hypothesis- (if two numbers are odd)

conclusion- (then their sum is even.)

4. hypothesis- (if two line segments have the same length)

conclusion- (then they are congruent)

5. hypothesis- (if one of its angles is obtuse)

conclusion- (a triangle is obtuse)

6. hypothesis- (if it measures 90°)

con.- (an angle is right)

7. hypo.- (if p is midpoint of ac)

con.- (then ap = pc)

8. hypo.- (if fy bisects < psm)

con.- (then < psy = < msy)

9. hypo.- (the sum of a number)

con.- (its reciprocal is zero)

10.hypo.- (the product of a number)

con.- (its reciprocal is 1)

not sure

Step-by-step explanation:

number of ways to choose 3 boys from 12 boys     = C(12,3)

number of ways to choose  2 girls from 7 girls        =   C(7,2)

total number of ways to choose the 5 members =     12C3* 7C2
