What is the speedup of the parallel solution?

A. 6 minutes
B. 4 minutes
C. 2
D. 3

Answers

Answer 1

Answer:

2

Explanation:

1+6+1=8

1+2+1=4

8/4=2

The qustion is asking for the parallel solution speadup.  It is a common mistake to give the speedup for for just the sorting stage 6/2=3.

Answer 2

The correct option is D. 3.

The calculation is as follows:

Parallel speedup represent the proportion of the time taken to determine something on a single processor versus the time taken to find out same thing on 'P' number or processors parallely.

Hence speedup = T1 ÷ TP.

Speedup = 6 ÷ 2

= 3.

What is wrong with the following code?
numl = int (input("Enter a number: "))
numz = int (input("Enter a number: "D)
num3 = int (input("Enter a number: "))
print ("The average is: + (numl + num2 + num3/3)
The last line should be print ("The average is: (numl + num2 + num/3)
The variables should be lnum, 2num, Bnum
It needs a into command
It needs a stro command

Answers

Code:

numl = int (input("Enter a number: "))

num2 = int (input("Enter a number: "))

num3 = int (input("Enter a number: "))

print ("The average is:" + ((numl + num2 + num3)/3))

Answer:

It needs a str command

Explanation:

Given

The above code

Required

Determine and correct the error

At the last line of the code, there is an attempt to print the average of the three numbers.

However, this will return an error because:

In order to print the literal "The average is:" and the numeric value of (numl + num2 + num3)/3, a str command is needed.

This converts (numl + num2 + num3)/3 to a literal and then print without error.

So, the correct instruction is:

print ("The average is:" + str((numl + num2 + num3)/3))
