Answer:
x = 2 * (y/5) feets
Step-by-step explanation:
Given that :
Actual dimension of mural = 15 feet by 8 feet
Scale drawing = 2 feet : 5 feet
2 feets on the scale drawing represents 5 feets of the actual drawing.
Drawing length (x)
Actual mural length (y)
x = 2 * (y/5) feets
Hence, dimension of scale drawing:
x = 2 * (15/5) ; x = 2 * (8/5)
x = 6 feets ; 3.2 feets
You refer to a rectangular distribution.
I.e. Area ∝ probability
so, length x height = area
=> 6 x height = 1
so, height = 1/6
Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes
=> 5.75 x 1/6 = 0.9583
Since this is uniformly distributed, there is no need to
find the height or standard deviation.
