Step-by-step explanation:
Let the distribution law followed is exponential law .
mean m = np where n = 15 , p = .2
m = 15 x .2 = 3
probability of 5 successes
=
=
= .1
Find the area of the shape provided
1 answer:
Answer:
Step-by-step explanation:
First you need to break the shape up to rectangles to make it easier to solve.
bottom rectangle : 15 x 3 = 45m^2
Top rectangle : 12 x 3=36m^2
Middle rectangle : 12-3-3=6 (because we already solved the top and bottom part of it)
we need to work out the base so we do 15-5= 5cm
6 x 5 = 30m^2
add them all together
30+36+45=111m^2
