The square root would be 8 because 8•8=64
The graph (by some miracle) has been uploaded for you. It is just about the first time I've done this sort of thing, and I've answered nearly 800 questions.
The first thing you have to do is study the graph. The two functions are
f(x) = 4^x That's the curved graph. (in red)
g(x) = x + 4. That's the straight line. (in blue)
You know that the first one is not a linear relationship because the x values go from integer values -2 to 2 (including 0). The y values are a bit different. They go from 1/16 to 16 with those integer values. So you could try y = 4^(-x). It doesn't work, but you could try it. It gives the table numbers for y in the reverse order that the table you are given goes. For x you get -2 -1 0 1 2 and for y you would get 16 4 1 1/4 1/16.
You could try y = (1/4)^x
For this try, you would get x = -2 -1 0 1 2 and for y = 16 4 0 1/4 and 1/16
but that doesn't work either.
You could try until you get y = 4^x which does work.
g(x) is a lot easier to deal with. It looks better behaved. as x goes up, so does y. You will find that the y values obey y = x + 4. You could try other lines, but that one works. Many times it's just a guess
Out of 100% there is a possibility of 95% choosing a white marble since there are more white marbles than green marble there is a much higher possibility.
There is only a 5% of the marble being green.
hope this answer helped - Maria S.
500-124=376
If 124 students liked snickers and 500 got surveyed then if we subtract how many got surveyed by how many liked snickers the answer would be 376.
12'5" is 149 inches. If 149in is the maximum, then anything above it including 162" cannot pass through safely.
