According to zimmels (1983), the sizes of particles used in sedimentation experiments often have a uniform distribution. in sedimentation involving mixtures of particles of various sizes, the larger particles hinder the movements of the smaller ones. thus, it is important to study both the mean and the variance of particle sizes. suppose that spherical particles have diameters that are uniformly distributed between .01 and .05 centimeters. find the mean and variance of the volumes of these particles. (recall that the volume of a sphere is (4/3)πr 3 .)

answer:

67

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
