In a game of luck, a turn consists of a player rolling 12 fair 6-sided dice. Let X = the number of dice that land showing "1" in a turn. Find the mean and standard deviation of X.

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

Suppose i pick a jelly bean at random from a box containing one red and eleven blue ones. i record the color and put the jelly bean back in the box. if i do this three times, what is the probability of getting a blue jelly bean each time? (round your answer to three decimal places.)

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
