Acompany just purchased a fleet of new cars for $30,500 per car. it is estimated that value of each car will depreciate by $4500 per year. let x be the age of the car in years, and y be the value of the car. write an equation that estimates the value of the car as a function of its age.

What is the y-intercept of the line given by the equation

Cor d? ? me ? max 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.

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6
