Step-by-step explanation:
It is given that the shape of a pile of sand is conical.
Diameter of cone is twice the height.
Let height of cone be h.
Diameter of cone = 2h
Radius of the cone =
It means radius of the cone is h.
Volume of cone is
where, r is radius and h is height of the cone.
Substitute r=h in the above formula.
Therefore, the volume of pile of sand is .
Answer:
0% probability cab tires depths would be shallower than 0.25cm.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability cab tires depths would be shallower than 0.25cm.
This probability is the pvalue of Z when X = 0.25. So
has a pvalue of 0.
0% probability cab tires depths would be shallower than 0.25cm.
