Answer:
80%!
you can put the amount spent on fruit over the total and compare it to a percentage table!
I feel like it would be mean or median, because there is no outlier, making it so that all of the numbers are closely put together.
Put the set into order.
25, 26, 27, 28, 29
So, we know that this is all in order, making it so that we know for sure that there is no outlier.
If you find the mean, it'll represent the data nicely.
We know that both the mean and median represent the data set nicely, because it just does. It's one of those things that are extremely painful and hard to fully explain and have someone understand, but don't worry, it makes sense.
So, it can't just be the mean only or the median only.
It also can't be the mode only, because THERE IS NO MODE!
So, our final answer is mean or median :)

Answer:
Step-by-step explanation:
We look for where 
. The way you find the answer is first, find the point 
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that 
intersects our line at 
, so .
Answer:
1. f(g(4)) - g(f(4)) = -6
2. f(f(x)) = 125x^4 - 250x^2 + 120
3. a + b = 0
4. g(4) = -9
Step-by-step explanation:
1.
First we need to find f(4) and g(4):
f(4) = 4 + 3 = 7
g(4) = 3*4 + 5 = 17
Then, we find g(f(4)) = g(7):
g(7) = 3*7 + 5 = 26
And we find f(g(4)) = f(17):
f(17) = 17 + 3 = 20
so f(g(4)) - g(f(4)) = 20 - 26 = -6
2.
To find f(f(x)), we use the value of f(x) for every x in f(x):
f(f(x)) = 5*(f(x))^2 - 5 = 5*(5x^2 - 5)^2 - 5 = 5*(25x^4 - 50x^2 + 25) - 5
f(f(x)) = 125x^4 - 250x^2 + 120
3.
To find f(g(x)), we use the value of g(x) for every x in f(x):
f(g(x)) = g(x) + 6 = ax + b + 6 = 3x + 3
ax + (b+6) = 3x + 3 -> a = 3 and b = -3
a + b = 3 - 3 = 0
4.
If we assume g(x) = ax + b, we have:
g(f(x)) = a*(2x - 3) + b = 2ax - 3a + b = 5 - 4x
2a = -4 -> a = -2
-3a + b = 5
6 + b = 5 -> b = -1
g(x) = -2x - 1
g(4) = -2*4 - 1 = -9
All of the answers will be less than five. for example if x=-3 n=2 which is less than 5
