The Algebra II test grades are posted, and all students taking the test scored over 75. Unfortunately, 5 students were absent for the test, so the teacher listed their scores as O
until the test is taken. Assuming that no score repeated more times than the O's, what
measure of central tendency would most likely give the the best representation of this
data? Explain.

Suppose there are 10 five and six-year-old attending a birthday party. when a 30 year old mother walks into the room with an infant in her arms, what happens to the mean age in the room? what happens to the standard deviation of ages in the room? a. the mean and standard deviation of both change. b. the meaning will change, but the standard deviation will stay approximately the same. c. i mean will stay approximately the same, but the standard deviation will change. d. the mean and standard deviation will both stay approximately the same.

Write an inequality and solve each problem. for exercises 11 and 12, interpret the solution.

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
