In order to take a sample of 1200 people from a population, i first divide the population into men and women, and then take a simple random sample of 500 men and a separate simple random sample of 700 women. this is an example of a:

a. randomized comparative experiment.
b. stratified random sample.
c. a simple random sample.
d. a multistage sample.
e. convenience sampling

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

Explain why the factor 1.5 is broke. into two numbers in the model.

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
