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:
.07 cents
Step-by-step explanation:
In order to solve this question all you need to do is divide the money spent by the amount of months. 45.50/612=0.0743464052 but since you cant spend .0043464052 of a cent we have to change the answer to .07. To check our answer is right all we need to do is multiply 0.0743464052 by 612=45.499999 so we know the answer is correct.
