If the following data were linearized using logarithms, what would be the equation of the regression line? Round the slope and y

Elis [28]

Answer:

log y = 0.576x + 0.139

Step-by-step explanation:

Given data:

x | 2 | 3 | 4 | 5 | 6
y | 21 | 69 | 261 | 1029 | 4101

Logarithms of y-values:

log 21 = 1.322
log 69 = 1.839
log 261 = 2.417
log 1029 = 3.012
log 4101 = 3.613

The ordered pairs:

(2, 1.322), (3, 1.839), (4, 2.417), (5,3.012), (6, 3.613)

Using an online calculator found the equation of the regression line:

y = 0.576x + 0.139

In our case it is:

log y = 0.576x + 0.139

Solve the system using elimination.

Wewaii [24]

Answer:

The answer is A.

Step-by-step explanation:

A. 3*(-9)= -27, 4*(-9)= -36, -27-(-36)= 9

B. 3*(-27)= -81, 4*(-9)= -36, -81- (-36) = -45

C. 3*3= 9, 4*9= 36, 9-36= -27

D. 3*(-3)= -9, 4*(-6)= -24, -9-(-24)= 15
