Suppose that we wish to predict whether a given stock will issue a dividend this year ("yes" or "no") based on x, last year’s percent profit. we examine a large number of companies and discover that the mean value of x for companies that issued a dividend was x¯ = 10, while the mean for those that didn’t was x¯ = 0. in addition, the variance of x for these two sets of companies was σˆ 2 = 36. finally, 80% of companies issued dividends. assuming that x follows a normal distribution, predict the probability that a company will issue a dividend this year given that its percentage profit was x = 4 last year.

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

this is poiselle's equation from fluid mechanic in physics. mech eng

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
