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)

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

wait this depends wether emily and zach how they are thinking.

yes they are the same.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
