Mira is making telescopes, each consisting of 2 lenses, 1 tube, and 1 eyepiece. lenses can be purchased only in packs of 50, tubes only in packs of 10, and eyepieces only in packs of 30. however, half of the lenses in each pack are not usable for telescopes. if all parts are used only for the telescopes, what is the minimum number of lenses mira must purchase to make a set of telescopes with no leftover components other than the unusable lenses? a. 75b. 150c. 300d. 600e. 7,500

Which number line represents the solution set for the inequality - x 24?

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
