Exercises 2
In a survey, a statistician analyzed the relationship between the Mothers-Heights (explanatory vari-
able x) and the Daughters-Heights (response y) by using the regression method. When he drew the
regression line, he found that at x = 0 the predicted response is yı = 29.9, and at x2 = 1 the pre-
dicted response is y2 = 30.43. Suppose that the standard deviations of Daughters-Heights is S, = 2.6
and Mothers-Heights is Sc = 2.35.
Please answer the following questions underneath each question.
1. Find the intercept "a" and slope "b" of the regression line of Daughters-Heights on Mothers-
Heights.

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.
