Answer:
Step-by-step explanation:
The computation of the number of weeks taken for empty the lake is shown below:
Given that
Lake empty in 6 weeks
The River could fill the lake in 20 weeks
Let us assume the combined lake be x
So, here the equation is
After solving this
x =
hence the number of weeks that take for empty the lake is
Answer:
a) 0.58
b) 0.0464
Step-by-step explanation:
A= The person is sick
B= The give a positive result
P(A)=0.03
P(A')=1-P(A)=1-0.03=0.97
P(B|A)=0.9
P(B|A')=0.02
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.9*0.03+0.02*0.97=0.0464
Answer:
Step-by-step explanation:
Answer:
360π cm³
Step-by-step explanation:
- Area of an Ellipse = (π)•(Major Axis)•(Minor axis)
- Volume of a Cylinder = (Base area)•(Height)
So:
Volume = [(π)(6 cm)(5 cm)]•(12 cm) = 360π cm³
Edit: That's (360)•(π), which can be plugged into a calculator and rounded if need be.
