Police sometimes measure shoe prints at crime scenes so that they can learn something about criminals. Listed below are shoe printâ lengths, footâ lengths, and heights of males. Construct aâ scatterplot, find the value of the linear correlation coefficientâ r, and find theâ P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Based on theseâ results, does it appear that police can use a shoe print length to estimate the height of aâ male? Use a significance of α=0.01. Shoe Print(cm) 30.9 29.3 30.6 31.7 27.2
Foot Length(cm) 25.1 25.4 29.0 26.0 24.6
Height (cm) 172.9 179.8 190.5 170.4 173.3

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
