20/4.... 5cm is ur answer
N-2=(10n+4)/2
Multiply each side by 2
2(n-2)=10n+4
Expand the brackets
2n-4=10n+4
Subtract 4 from each side
2n-8=10n
Subtract 2n from each side
-8=8n
Divide each side by 8
-1=n
Hope this helped
Answer:
H = 1/30
H = 0.0333
0.033
Step-by-step explanation:
The time spent waiting at a traffic light can be considered a random variable with values from 0 seconds,
it’s green when you approach and can go on through, to 30 seconds with the following distribution shape
The entire area under the distribution curve must be 1.
Let assume the Shape is rectangle
Given
Time taken from 0s to 30s = 30s - 0s = 30s
To find height of the distribution?
Let H = the height of the distribution
Based on the above assumption;.
H * 30 = 1 --- make H the subject of formula
H = 1/30
H = 0.0333
To three decimal places is 0.033
<h3>Hence, the calculated height of the distribution is 0.033</h3>
