Here is the histogram of a data distribution. All class widths are 1. Which of the following numbers is closest to the mean of this distribution ?

Consider circle o, where and . m∠bpd °. °.

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2.

Determine the required value of the missing probability to make the distribution a discrete probability distribution. x p(x) 3 0.23 4 ? 5 0.51 6 0.08 p(4) = nothing  (type an integer or a decimal.)
