Answer:
B: 280
Step-by-step explanation:
The regression line predicts that when x equals 5:
![log_{10}(y) = 2.447](https://tex.z-dn.net/?f=log_%7B10%7D%28y%29%20%3D%202.447)
In order to find the value for y, one must simply apply the following logarithmic property:
if :
then: ![b^c = a](https://tex.z-dn.net/?f=b%5Ec%20%3D%20a)
Applying it to this particular problem:
![log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280](https://tex.z-dn.net/?f=log_%7B10%7D%28y%29%20%3D%202.2447%5C%5C10%5E%7B2.447%7D%3D%20y%5C%5Cy%3D280)
Therefore, the regression line predicts y will equal 280 when x equals 5.
Answer:
line 2
Step-by-step explanation:
on line 2 the two minuses at the end turn into a + (where the -2 is there should be a +2) because - x - = +
The answer is E=mc², Einstein's revolutionary formula.
