The measures of three sides of a triangle can be represented by 2x, 3x and -5, and 4x + 2. the perimeter of the triangle is 65 inches.
a) give an equation to represent this situation.
b) solve for x
c) what are the three lengths of a triangle?

This assignment is past the original due date o this data is from a sample. calculate the mean, standard deviation, and variance 16.7 11.1 46.7 14.8 13.3 16.6 18.5 47.3 42,8 show the following answers to 2 decimal places. sample mean- sample standard deviation ( use the standard deviation above for your calculation.) sample variance ooops- now you discover that the data was actually from a population! so now you must give the population standard deviation.
