Answer:
4 gallons with 65% soultion
Step-by-step explanation:
1. add the number of gallons together to find the total amount of the liquid in this case 4 gal.
2. Find the amount of solution in each part. In this case from the 3 gal there is 2.4 solution and for the 1 gal its 0.2 solution. I found this by finding the percentage.
3. Next, add the amounts of solution together to get 2.6 solution in all.
4. lastly, caluculate how much percent 2.6 is out of the total 4 gals.When you do this in all you get 4 gal with a 65% solution.
First problem:
The answer is C because theoretically it should have a 50% of landing
heads but instead it lands heads 56% of the time. Thus this is 6% higher
than 50%. It's not D because there is not specified detail of how the
person got this data so you can assume that the person did a fair
survey/data collection.
Second problem:
So in a data size of 490, 140 of them we trout. This means that 140/490 or 28.57% of the fish are trout. This means that in a sample size of 5000 fish, 5000*0.2857 or 1428.57 are trout.
Third problem:
The Science students seem to have a higher average score because the average score of Math students are:
(32+33+34+34+35+37+39+40+40)/9=36
average score of Science students are:
(41+42+43+43+46+46+47+49+49)/9=45.111
