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
The Formula for the volume of a sphere is 
- r --> length of radius --> 2ft
<u>Volume</u> = 
The <u>volume is 33.51 cubic feet</u>

Hope that helps!
The 4 in 64,781 has a thousands value. The 2 in 25,409 has a ten thousands value 1000 times 10 equals 10,000 so the answer is.....10 times greater.
(Btw please put elementry questions in elementry and high school questions in high school plz)
