For each one, guess whether the SD is around 1, 2, or 10. a) 49, 51, 49, 51, 49, 51, 49, 51, 49, 51 b) 48, 52, 48, 52, 48, 52, 48, 52, 48, 52 c) 48, 51, 49, 52, 47, 52, 46, 51, 53, 51 d) 54, 49, 46, 49, 51, 53, 50, 50, 49, 49 e) 60, 36, 31, 50, 48, 50, 54, 56, 62, 53

Write the rational number in lowest terms 99/-15

Square a has a side length of (2x-7) and square b has a side length of (-4x+18). how much bigger is the perimeter of square b than square a?and show all work! you so

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.
