The equation yˆ=0.8579x+73.4728 models the mass of a mammal’s brain, in grams, where x is the mass of the mammal, in kilograms. according to the regression equation, what is the approximate mass of a mammal's brain with a body that has a mass of 60 kg? about 74 g about 83 g about 125 g about 150 g

Step-by-step explanation:

125 grams.

Step-by-step explanation:

We have been given an equation , which models the mass of a mammal’s brain, in grams, where x is the mass of the mammal, in kilograms.

To find the approximate mass of a mammal's brain with a body that has a mass of 60 kg, we will substitute  in our given equation.

Therefore, the mass of the mammal's brain is approximately 125 grams.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
