The answer is 2416.5 and i did it on paper
Median
Median is the mean of 18 and 32 because they are in the middle, so it's 25. Median is the best representation because most numbers are around 20-30. 115 makes the mean go super high, which is not good, 11 drags the mean down, which is not good either.
Extras:
Mean: 11+11+18+32+34+115 =
221 divided by 6 =
36.88
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let's help out by giving some values to the question.
Let's say there are 230 students in a school. This number is 15% more than it was last year. Calculate the number of students last year.
Let the number of students last year be x.
Since there's a 15% increase, this implies that (100% + 15%) = 115% of x equals to 230. This will be:
115% of x = 230
115% × x = 230
115/100 × x = 230
1.15x = 230
x = 230/1.15
x = 200
There were 200 students last year.
Just assign the missing values and use the above method and you'll get your answer.
F^-1(x) = -4 + 2x
Interchange the variables, then solve for y.
The first equation gives
Differentiating with respect to 
gives
for some constant 
. So
and by the fundamental theorem of calculus,
