NORTH CAROLINA REAL ESTATE PRACTICE TEST QUESTIONS

Create a user$-$defined function named yourLastName$\_$C$7\_$p$3.$m that converts pressure

from psi $($pounds per square inch$)$ to $Pa($Newtons per square meter$).$ Use the following

facts to aid in the conversion.

$1$ pound $=4\mathrm{.}448$ newtons

$1$ meter $=39\mathrm{.}37$ inches

From your main script, use the function to convert $1000$ psi into Pa units. Your

function should have some comments that explain where the "magic" numbers are

coming from.

Write a user$-$defined function named yourLastName$\_$C$7\_$p$11.$m that computes GPA

based on data from a number of courses. Your main script file should load

MATLAB$\_$C$7-11.$txt and extract the Grade and Credit Hours. The grade vector contains

grades expressed on the $4-$point scale. The Credit Hours vector lists the number of

credits for each of the eight courses. Your function should receive the two vectors and

return a single GPA number that is rounded off to two digits after the decimal. Hint:

Use the internet or help files to find out how to do the rounding.
