Answer /Explanation
load hw92.dat
FID = fopen(file, 'r');
if FID == -1
fprintf('ERROR CANNOT OPEN FILE TO READ!');
else
fclose(file);
The we have:
datacell = textscan(FID, 'x%fy%f', 'CollectData', 1);
xycoords = datacell{1};
x 0 y 1
x 1.3 y 2.2
x 2.2 y 6
x 3.4 y 7.4
x 4.2 y 5.5
x 4.4 y 4.5
x 6.2 y 7.8
x 7.7 y 11.1
x 8.2 y 11.5
x 9.9 y 15.2
x 7.2 y 9.5
x 8.9 y 12.5
end
Answer:
=vlookup(h14, a5:h11,8,false)
Explanation:
Here, h15 is the cell in which we need the output and the value to be matched in rows to find the exact row is h14, and the range is expressed as a5:h11. Now to find the column number, we need to figure out the first and the concerned column. So, the concerned column is in which the total attendance is being listed and it is h(h14), and the first column is a. So, the column number is a=1 h=8, =8. And since we need the exact match, the value of the fourth argument is false. And thus, we have the above formula. Remember. vlookup formula is:
=vlookup(cell where the result is to be placed, range, column number in the same row as h14, exact match or approximate match). For exact match it's false, and for the approximate match, it's true.

Answer:
Information
Explanation:
Good decisions are normally based on facts which are tangible information that can be analysed to show trends of key figures such as sales, income, production that are so critical in business.
