question 53

Multiple Choice

Provide an appropriate response. For the data below, determine the logarithmic equation, y=a+b ln x that best fits the data. Hint: Begin by replacing each x -value with ln x then use the usual methods to find the equation of the least squares regression line.
$\begin{array} { r r r r r r } x & 1.2 & 2.7 & 4.4 & 6.6 & 9.5 \\\hline y & 1.6 & 4.7 & 8.9 & 9.5 & 12.0\end{array}$

• A) \(\hat { y } = - 0.458 + 5.36 \ln x\)
• B) \(\hat { y } = - 0.881 + 4.86 \ln x\)
• C) \(\hat { y } = - 1.81 + 6.91 \ln x\)
• D) \(\hat { y } = 0.457 + 5.06 \ln x\)

Definitions:

Quadrature Power

Same as VARs or wattless power.

RL Circuit

An electrical circuit composed of resistors (R) and inductors (L) used to analyze the behavior of circuits with respect to changing currents.

Power Values

Numerical quantifications that represent the rate at which energy is converted, transferred, or used in an electrical circuit, typically measured in watts.

Series RL Circuit

An electrical circuit comprising resistors (R) and inductors (L) arranged in a sequential manner, where the current through each component is the same.
