Answer:
y = 542 years
Step-by-step explanation:
Given that,
The regression equation, y= 4.39x-6.77 is used to predict the age of a tree.
y is age of a tree and x is diameter
Put x = 125 cm
Put the value of x in above equation.
y = 4.39(125)-6.77
=548.75 - 6.77
= 541.98
or
y = 542
So, the tree is 542 years old.
