Abstract This study was undertaken to determine the association between life spans and breed size in the dog, based upon data derived from the pet population.
Seventy-seven American Kennel Club breeds were analyzed with data collected for more than 700 dogs. Multiple linear regression analysis was carried
out with longevity as the dependent variable and height or weight as the independent variable. A negative correlation was observed between height and
longevity (r = -0.603, p < 0.05), and between weight and longevity (r = -0.679, p < 0.05). Weight was the significant predictor of life span (p < 0.001),
revealing that breeds smaller by weight generally live longer than heavier breeds. These data form the ground work for investigations of aging utilizing
the dog as a model and provide owners with a quantitative method for predicting lifespan of dog breeds, thereby aiding in pet selection.

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
