Answer:
40%
Step-by-step explanation:
According to the provided information:
The likelihood of rain on Saturday stands at 25%.
P(Sunday)=25%=0.25
If it rains on Saturday, the probability of rain on Sunday rises to 50%.
P(Sunday|Saturday)=50%=0.5
If it does not rain on Saturday, the chance of Sunday rain is 25%.
P(Sunday|No Rain on Saturday)=25%=0.25
We aim to find the probability of rain on Saturday given that it rained on Sunday, P(Saturday|Sunday).
P(No rain on Saturday)=1-P(Saturday)=1-0.25=0.75
Using Bayes' theorem for conditional probabilities:
P(Saturday|Sunday)=
=
=0.4
Thus, there is a 40% likelihood that it rained on Saturday given the conditions on Sunday.
Step-by-step explanation:
Given are
Sides of the triangle measure 4 units, 6 units, and 7.21 units.
We need to compute the area of a circle whose circumference matches the triangle's perimeter.
The triangle's perimeter corresponds to the circle's circumference.
4 + 6 + 7.21 = 2πr, where r is the radius of the circle.
r = 2.73 units
Circle's area is:

or
A = 24 square units
Thus, the circle’s area is 24 square units.
Option D is indeed correct, as it ensures that the post's point is equidistant from the ground, maintaining a perpendicular angle at two points on the surface.
