Aset of data has a normal distribution with a mean of 50 and a standard deviation of 8. what percent of the data should be greater than 34?

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)
