Answer:
By summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum.
Step-by-step explanation:
A spherical slab is characterized by the radius as its inherent variable and cylindrical slabs by its radius and height. The volume of the spherical slab can be approximated by summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum. (Please see image attached below for further details).
Answer:
a) 0.71
b) 0.9863
Step-by-step explanation:
a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000
-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:
Hence, the probability of a house price below $500,000 is 0.71
b. -Let X be the mean price of a randomly selected house.
-Since the sample size 40 is greater than 30, we assume normal distribution.
-The probability can therefore be calculated as follows:
Thus, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
