Question

If log(y) = 1.01 + 0.72*log(x), and Bigfoot's weight is estimated to be about 127 kilograms (kg), how big do you expect Bigfoot's brain to be?

A) 20 cm³
B) 50 cm³
C) 100 cm³
D) 200 cm³

Answer 1

To find the expected size of Bigfoot's brain based on the given equation, substitute Bigfoot's weight into the equation and solve for y. The expected size of Bigfoot's brain is approximately 100 cm³.

Step-by-step explanation:

To find the expected size of Bigfoot's brain, we need to substitute the weight given into the equation for log(y). Given that Bigfoot's weight is estimated to be 127 kg, the equation becomes:

log(y) = 1.01 + 0.72*log(127)

Simplifying further, we can calculate the value of log(y) and then find y by taking the antilog of that value.

After solving the equation, we find that the expected size of Bigfoot's brain is approximately 100 cm³. Therefore, the correct answer is C) 100 cm³.
