He did not perform enough trials. The more trials you perform, the closer it gets to the predicted outcome.
If 2 of 12 eggs are cracked, then 10 are not cracked.
SO
10/12=5/6=about 0.83
0.83 of total eggs not cracked is also equivalent to 83 percent as asked in the problem :)
Answer: 7
Step-by-step explanation:
Here the given inequality that shows the number of humming birds(H) and the number of sunbirds(S) that must pollinate the colony so it can survive until next year,
6 H + 4 S > 74
If This year, 8 hummingbirds pollinated the colony.
By putting H=8 in the above inequality,
We get,
6× 8 + 4 S > 74
⇒ 48 + 4 S > 74
⇒ 4 S > 26
⇒ S > 6.5
Hence the least number of sunbirds is 7.
The solution is at what point the two lines intersect.
Plug y into the other equation to get: 5x-4(5-3x)=-3
Multiply it out: 5x+12x-20=-3
Combine like terms and add 20 to both sides: 17x=17
Divide both sides by 17: x=1
Now plug the x value back into any equation to get the y value.
So you get y=5-3(1) --> y=2
The solution is (1, 2)
