Answer:
B. 57
Step-by-step explanation:
Given:
A regression line for some data transformed with logarithms predicts that when
[tex]x=7 , \log(y)=1.755[/tex]
To find what will the line predicts [tex]y[/tex] value when [tex]x=7[/tex] to nearest whole number.
Solution:
When [tex]x=7[/tex]
[tex]\log(y)=1.755[/tex]
We can solve for [tex]y[/tex] by using logarithm properties.
By logarithm properties.
If [tex]\log(a)=b[/tex]
[tex]a=10^b[/tex]
Thus, we have:
[tex]y=10^{1.755}[/tex]
∴ [tex]y=56.88\approx 57[/tex]
