Let the weightage of Ease of Use be x
Ease of Use = x
<span>Compatibility is 5 times more than ease of use:
</span>Compatibility = 5x
<span>Reputation is 3 times more important than compatibility:
</span>Reputation = 3(5x)
Reputation = 15x
<span>Cost is 2 times more important than reputation:
</span>Cost = 2(15x)
Cost = 30x
So the weightage are:
Ease of Use : 1
Compatibility : 5
Reputation :15
Cost : 30
Answer:
Step-by-step explanation:
Time for first race 57.9seconds
x=time for first half of race
x-4.7=second half of race
Equations is
x + (x-4.7)=57.9
2x-4.7=57.9
2x=57.9+4.7
2x=62.6
x=31.3
Check answer
31.3 + (31.3-4.7)=57.9
31.3 +26.6=57.9
57.9=57.9
Answer:
x = 11
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
-10x + 9 = -11
-10x = -20
x = 2
Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
