Answer 1

Answer:

B. 57

Step-by-step explanation:

Given:

A regression line for some data transformed with logarithms predicts that when

$x=7 , \log(y)=1.755$

To find what will the line predicts $y$ value when $x=7$ to nearest whole number.

Solution:

When  $x=7$

$\log(y)=1.755$

We can solve for $y$ by using logarithm properties.

By logarithm properties.

If $\log(a)=b$

$a=10^b$

Thus, we have:

$y=10^{1.755}$

∴ $y=56.88\approx 57$
