The cost of a home depends on the number of bedrooms in the house. suppose the following data is recorded for homes in a given town price (in thousands) 300 250 400 550 317 389 425 289 389 559 no. bedrooms 3 3 4 5 4 3 6 3 4 5 a) make a scatterplot b) fit the data with a least squares regression line. c) give a 95% confidence interval for the slope. d) if one house has one more number of rooms than another house, how much additional cost would we expect for the price? e) test the hypothesis that an extra bedroom costs $60,000 against the alternative that it costs more.

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
