Suppose that about 85% of graduating students attend their graduation. A group of 22 graduating students is randomly chosen. Part (a) Part (b) Part (c) O Part (d) How many students are expected to attend their graduation? (Round your answer to the nearest whole number.) students O Part (e) Find the probability that 17 or 18 attend. (Round your answer to four decimal places.) O Part (f) Based on numerical values, would you be surprised if all 22 attended graduation? O Yes. The probability of all 22 students attending graduation is small (less than 5%). O No. The probability of all 22 students attending graduation is large (more than 10%).

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.
