Answer:
1.84
Explanation:
Operation on old system
Add operation = 50% = 0.5
Multiply = 30% = 0.3
Divide = 20% = 0.2
T = total execution time
For add = 0.5T
For multiplication = 0.3T
For division = 0.2T
0.5T + 0.3T + 0.2T = T
For new computer
Add operation is unchanged = 0.5T
Multiply is 10 times faster = 0.3T/10 = 0.03T
Divide is 15 times faster = 0.2T/15= 0.0133T
Total time = 0.5T + 0.03T + 0.0133T
= 0.54333T
Speed up = Old time/ new time
= T/0.54333T
= 1/0.54333
= 1.84
<u>Answer</u>:
Every person in this world has not connected to the Internet.
<u>Explanation</u>:
Now I will tell you why? because mostly in the developing countries, people are using the internet affordably and in the 15% cities, there are no electricity so that the internet cannot be connected throughout these cities.
The 31% of the people around the world stay outside the network coverage areas which makes them difficult to get proper internet connection. Approximately 13% of the people lives below the International Poverty Line in this world.
