<h2>Answer:</h2>

We can do it by using the format tab

<h2>Explanation:</h2>

We can change the background of a group of cells by selecting the cell or range of cells we want to format. We should Click Home > Format Cells dialog launcher, or press Ctrl+Shift+F from the keyboard. Then on the Fill tab, under Background Color, we pick the color we want. To use a pattern with two colors, we pick a color in the Pattern Color box, and then pick a pattern in the Pattern Style box. In this tab we can also select gradient or single color.

Row array gameScores contains all player scores. Construct a row array highScores than contains all player scores greater than m

Sever21 [200]

Answer:

The solution is written using Python as it has a simple syntax.

def getHighScores(gameScores, minScore):
meetsThreshold = []
for score in gameScores:
if(score > minScore):
meetsThreshold.append(score)
return meetsThreshold
gameScores = [2, 5, 7, 6, 1, 9, 1]
minScore = 5
highScores = getHighScores(gameScores, minScore)
print(highScores)

Explanation:

Line 1-8

Create a function and name it as getHighScores which accepts two values, gameScores and minScore. (Line 1)
Create an empty list/array and assign it to variable meetsThreshold. (Line 2)
Create a for loop to iterate through each of the score in the gameScores (Line 4)
Set a condition if the current score is bigger than the minScore, add the score into the meetsThreshold list (Line 5-6)
Return meetsThreshold list as the output

Line 11-12

create a random list of gameScores (Line 11)
Set the minimum score to 5 (Line 12)

Line 13-14

Call the function getHighScores() and pass the gameScores and minScore as the arguments. The codes within the function getHighScores() will run and return the meetsThreshold list and assign it to highScores. (Line 13)
Display highScores using built-in function print().

Suppose your company has decided that it needs to make certain busy servers faster. Processes in the workload spend 60% of their

vekshin1

Answer:

CPU need 50% much faster

disk need 100% much faster

Explanation:

given data

workload spend time CPU = 60%

workload spend time I/O = 40%

achieve overall system speedup = 25%

to find out

How much faster does CPU need and How much faster does the disk need

solution

we apply here Amdahl’s law for the overall speed of a computer that is express as

S = $\frac{1}{(1-f)+ \frac{f}{k} }$ .............................1

here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component

so put all value in equation 1 we get

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.6)+ \frac{0.6}{k} }$

solve we get

k = 1.5

so we can say CPU need 50% much faster

and

when f = 0.4 and S = 125 %

put the value in equation 1

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.4)+ \frac{0.4}{k} }$

solve we get

k = 2

so here disk need 100% much faster
