A quiz has 50 multiple choice questions. Each question has 3 possible answers, one of which is correct. A correct answer is worth 2 points, but a point is taken off for each incorrect answer. A student answers all 25 questions by guessing at random. In each case present the problem with an appropriate box model. Find the expected value and the standard error for the sum of 25 draws. Interpret this sum in terms of the scores.

Needmax recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
