Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of O and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than 0.81.
What is the probability?

The actual length of side t is 0.045 cm. use the scale drawing to find the actual side length of w. a) 0.06 cm b) 0.075 cm c) 0.45 cm d) 0.75 cm

Atemperature of 1.64◦f corresponds to answer in units of ◦c.

He ! a group of farmers planned to clean 80 acres of wheat per day to finish the work on schedule. right before the work started, they received a new piece of machinery that them clean 10 more acres per day than originally planned. as a result of increased productivity in the last day before the deadline they only had to clean 30 acres. how many acres of wheat did the group of farmers have to clean?
