3.X is random variable representing the concentration in kg/day/km of a nonpoint source load of total dissolved solids in a river at a certain time and location. The random variable is assumed to be model using log normal distribution with a mean value of 8,000 and a coefficient of variation of 0.4. a. What is the mean value and standard deviation of ln(X)

so then what are you asking?

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

d is the answer
