Report the speedup and efficiency in each of the following $5$ cases. You need not reduce the mathematical expressions to a single number, but the numerical expressions you have must be correct to get credit. Mention the problem number, along with the correct term $($efficiency and speedup$)$ to show which numerical expression is for speedup and which numerical expression is for efficiency. Ts denotes the time needed to complete the sequential part of the task. Tp denotes the time needed to complete the parallelizable part of the task with one processor. N denotes the number of processors.
