Is the task set shown in Table 11.26 schedulable using the simple utilizationbased test given in Equation (11.1)? Is the task set schedulable using the response time analysis?
$$
\begin{array}{ccc}
\hline \text { Task } & \text { Period } & \text { Execution time } \\
\hline a & 50 & 10 \\
b & 40 & 10 \\
c & 30 & 9 \\
\hline
\end{array}
$$
