elephone number is used to receive both voice calls and fax messages. Suppose that 40% of the incoming calls involve fax messages, and consider a sample of 15 incoming calls. A USE SALT the expected number of calls among the 15 that involve a fax message? the standard deviation of the number among the 15 calls that involve a fax message? (Round your answer to three decimal places.) the probability that the number of calls among the 15 that involve a fax transmission exceeds the expected number by more than 2 standard deviations? (Round your answer to three decimal

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.
