Answer: y=12 x=28
Explanation:
x=Amount of Small Lanterns y=Amount of Large Lanterns
25x+40y=1180
x+y=40
x=40-y
25(40-y)+40y=1180
1000-25y+40y=1180
1000+15y=1180
15y=180
y=12
x+12=40
x=28
The answer is 64
- the side length of the square is 8 units
- area of square = a^2
- 8^2
- 64 :)
The probability is 7/20.
There are 20 outcomes in the sample space:
2(1) 2(3) 2(5) 2(7) 2(9)
3(1) 3(3) 3(5) 3(7) 3(9)
4(1) 4(3) 4(5) 4(7) 4(9)
5(1) 5(3) 5(5) 5(7) 5(9)
Out of these, 14 are two digit products. Out of those 14, only 7 are odd. Thus the probability is 7/20.
Answer: The first experiment has M probabilities, and the second has I(m) outcomes, that depends on the result of the first.
And lets call m to the result of the first experiment.
If the outcome of the first experiment is 1, then the second experiment has 1 possible outcome.
If the outcome of the first experiment is 2, then the second experiment has 2 possibles outcomes.
If the outcome of the first experiment is M, then the second experiment has M possibles outcomes.
And so on.
So the total number of combinations C is the sum of all the cases, where we exami
1 outcome for m = 1

2 outcomes for m=2

M outcomes for m = M
C = 1 + 2 + 3 + 4 +...´+M
