Question$-1(25$ points$)$

Create a function to determine test grades based on the soore and

assuming a single input into the function. The function must give an

error message to the input when the input is greater than $160$ and

smaller than $8.$ The grades should be based on the following criteria:

Question$-2(25$ points$)$

This problem requires you to generate temperature conversion tables. Use the following equations,

which describe the relationships between temperatures in degrees Fahrenheit $(T_p),$ Kelvin $(T_k).$

$T_K=(T_r+459\mathrm{.}67)*\frac{5}{9}$

Generate a table of conversions from Fahrenherit to Kelvin for values from $F$ to $200F.$ Allow the

user to enter the increments in degrees $F$ between lines. Use disp and fprintf to create a table with a

title, column beadings, and appropriate spacing.

Question$-3(25$ points$)$

What will be the output in the command

window if the following matlab program is

exccuted?

$a=4$;

$b=a^{2}a$;

$c=a^2{a}^{2}a$;

$d=sqrt(a)$;

fprintf$(\%.4\mathrm{.}0$ square equals $\%4\mathrm{.}0$ of $\text{'},$ a$,$ b$)$

fprintf$(\%4\mathrm{.}0$ cube equals $\%4\mathrm{.}0.1w\text{'},$ a$,$ c$)$

fprintf$($The square root of $\%2\mathrm{.}0$ is $)$

Question$-4(25$ points$)$

What will be the output in the command window if the following

matlab program is executed?

${\displaystyle \underset{?}{\overset{?}{}}}1=0,$

${\displaystyle \underset{?}{\overset{?}{}}}2=0,$

$N$ III $9$

for $k=1$:$N$

sum $1=$ sum $1+k$;

$if($ mod$(k,3)=0)$

sum $2={\displaystyle \underset{?}{\overset{?}{}}}2+k$;
