Answer:
= 2.31
Step-by-step explanation:
0.462 ÷ .2 = 2.31
Hope this helps : )
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.
Answer:
width = w
length= 3w+1
perimeter= 5(3w+1) -45
perimeter = 2(l+b)
5(3w+1) -45 = 2{(3w+1)+w}
15w - 40 = 8w+2
6w = 42
w =7
therefore width = <u>7</u>
length= 3w+1 = <u>22</u>
perimeter= <u>65</u>
