for science class, a student recorded the high and low temperatures, in fahrenheit, over a ten day period in september. the data is shown in the table.

low temperature, x 26 28 30 32 34 35 37 38 41 45

high temperature, y 49 50 57 54 60 58 64 66 63 72

a) what is the correlation for a linear model of this data? round to the nearest hundredth. r =

b) ten high and low temperatures in october are recorded and have a correlation coefficient of 0.89. in which month is there a stronger correlation between the high and low temperatures? explain your answer.

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2
