Question

* WILL GIVE BRAINIEST*

Answer 1

Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

$log_{10}(y) = 2.447$

In order to find the value for y, one must simply apply the following logarithmic property:

if : $log_{b}(a) = c$

then: $b^c = a$

Applying it to this particular problem:

$log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280$

Therefore, the regression line predicts y will equal 280 when x equals 5.
