Suppose your company has decided that it needs to make certain busy servers 50% faster. processes in the workload spend 60% of their time using the cpu and 40% on i/o. in order to achieve an overall system speedup of 25%: how much faster does the disk need to be?

The correct answer is 100% more faster.

Explanation:

According to the scenario, the computation of the given data are as follows:

Overall system speedup (S) = 25% + 100% = 125% = 1.25

Work done by Faster components (F) = 40% = 0.4

So, we can calculate the speed of disk (K) to run by using following formula:

S =

So, by putting the value, we get

1.25=

After solving this, we get

K = 2

That means Disk has to twice its speed.

Hence, Disk needs to be 100% faster.

a progressive tax is a tax that imposes a lower tax rate on low-income earners compared to those with a higher income, making it based on the taxpayer's ability to pay. that means it takes a bigger percentage from high income earners than it does from low income people.

answer: a. the kind of population living in your neighbourhood.

the census explorer data tool by the us census bureau allows the user to zoom in on any neighbourhood within the united states and find the kind of people residing in that by race and age.  

the tool needs to needs to be used twice – once in order to find what type of people reside in a neighbourhood, and then to see the age groups of the people in the same neighbourhood.
