Astandardized exam's scores are normally distributed. in a recent year, the mean test score was 14781478 and the standard deviation was 311311. the test scores of four students selected at random are 18701870, 12001200, 21802180, and 13801380. find the z-scores that correspond to each value and determine whether any of the values are unusual.

What is the pattern in the values as the exponents increase?

The table represents a linear function. what is the slope of the function? –6 –4 4 6

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
