It was 4 years ago... i got 33/40 on it and remember basically doing all the graphs i knew about (histogram, culmulative frequency graph, pie charts, box and whisker diagrams etc) just make sure you use them in the correct situation. Ive also heard it's pretty much impossible to get 40/40 unless you use original data... good luck
What is formula of differentiation?
The answer by Broad Way covers a very narrow range of situations. If f(x) is a function of x then the derivative of f(x) and this is defined asthe limit, as h tends to 0, of [f(x+h) - f(x)] / h, if it exists.
In graph form, [f(x + h) - f(x)] / h is the gradient of f(x) between the points at which the abscissa are x and x+h. As x+h comes closer and closer to x (ie as h tends to 0) the ratio tends to the gradient of the tangent to the curve f(x) at the point x.

C program to display the numbers between 1 to 100 which are having unit's place digit as 1?
Here's one way to do it:
#include <stdio.h>
int main(int argc, char *argv[]){
int n;
for( n = 1; n < 100; n++){
if(n % 10 == 1) printf("%i ", n);
}
return 0;
}
And here's a more efficient way to do it:
#include <stdio.h>
int main(int argc, char *argv[]){
int n;
for( n = 1; n < 100; n += 10){
printf("%i ", n);
}
return 0;
}

Is the range zero in a data set consisting of 1000 values that are all different?
No. The range is the maximum value less the minimum value. If all the values are different, the maximum must be different from the minimum. Consequently, the max minus min must be greater than zero.
How do two variables display correlation?
One variable must react to the other. If represented by a graph, a visible trend will appear and a "trend line" should easily be visualized and determined.
What information does a line chart compare?
