Answer:
Probability of the day to be a snow day is 0.34
Step-by-step explanation:
We have the data,
Out of 21 which had less than 3 inches of snow, 5 were snow days.
Out of 8 days which had more than 3 inches of snow, 6 were snow days.
So, we get,
Total number of days = 21 + 8 = 29
Total number of snow days = 5 + 6 = 11
Thus, the probability that the day will be a snow day is i.e. 0.34
Hence, the probability of the day to be a snow day is 0.34.
Answer:
Step-by-step explanation:
The pressure exerted by an object is given by:
where
F is the magnitude of the force
A is the area of the surface perpendicular to the force
In this problem, the force is the weight of the books + the shelf, which is given by
where
m = 262 kg is the total mass
is the acceleration of gravity
Substituting,
The area of the four legs is:
Therefore, the pressure exerted on them is:
