Two integers from 1 to 30 are chosen by a random number generator. what is the probability that both numbers are less than 12?

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).

Which functions shave a maximum and are transformed to the left and down of the parent function ,check all that apply f(x) = x2? p(x) =14 (x+7)2 + 1

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles
