box contain 4 numbers: 1, 2, 4, 8 Two draws will be made, without replacement. Let the random variable X be the largest value drawn divided by the SQUARE of the smallest value drawn. Hint: if I were to draw the 8 and the 2, I take the largest draw (8) and divide by the square of the smallest draw (22 or 4) which yields 2. Hence, a possible value for X is 2. The following is the probability distribution of X Value of X ? 1 2 4 8 Probability 1/6 1/6 ? 1/6 1/6 What is the missing value of x? A) 0.25 B) 0 C) 0.5 D) 0.75 E) 16
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
