he correct answer is 260

Answer 2

Answer:

The correct option is 2.

Step-by-step explanation:

From the given pictures it is clear that the linear regression line for the given data is

$y=3.98x+5.022$

We have to find the best prediction for the value of y when x=64.

Substitute x=64 in the given equation.

$y=3.98(64)+5.022$

$y=254.72+5.022$

$y=259.742$

$y\approx 260$

Therefore the correct option is 2.
