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?

Respuesta :

the answer is----about 125 g

Answer:

125 grams.

Step-by-step explanation:

We have been given an equation [tex]y=0.8579x+73.4728[/tex], 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 [tex]x=60[/tex] in our given equation.

[tex]y=0.8579*60+73.4728[/tex]

[tex]y=51.474+73.4728[/tex]

[tex]y=124.9468\approx 125[/tex]

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