Answer:
- 8 years: Rs. 64
- 9 years: Rs. 72
- 10 years: Rs. 80
Step-by-step explanation:
The sum of ages is 8+9+10 = 27, so each year of age is rewarded by ...
216/27 = 8 . . . Rs
Then age 8 gets 8(Rs. 8) = Rs. 64
age 9 gets 9(Rs. 8) = Rs. 72
age 10 gets 10(Rs. 8) = Rs. 80
10 is the answer because using the Pythagorean theorem 6^2 + 8^2 = 100. The square root of 100 would be 10
Answer:
AUB = {E1, E2, E4, E6, E7}
Step-by-step explanation:
Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.
AUB = {E1, E2, E4, E6, E7}
Note that the way you arrange does not matter as well.
I hope you find this solution useful?
