ASAP HELP What is the equation of the least-squares regression
line?
Bacteria = -0.023 + 4.20 In(Time)
Bacteria growth was measured over a one-month
period. The number of cells were counted for a certain
number of days. A regression analysis was completed
and is displayed in the computer output.
Regression Analysis: ln (Bacteria) versus Time
Predictor Coef SE Coef T
Constant
2.077 0.03
69.233 0.000
Time
0.142 0.001
122.524 0.000
S=0.030
R-Sq=0.99 R-Sq(adj)=0.999
O In(Bacteria) = 0.142 + 2.077(Time)
P
In(Bacteria) = 2.077 + 0.142(Time)
O In(Time) = 2.077 + 0.142(Bacteria)

So the intensity of the light be smaller in second case with the polarizers at 90 degree with the vertical

Explanation:

When two polarizers are arranged at 45 degree and 90 degree in series

so here the intensity of light coming out of the polarizers is given as

now for second polarizer we have

now in other case when two polarizers are inclined 90 degree to the vertical

so final intensity in second case will be ZERO

So the intensity of the light be smaller in second case with the polarizers at 90 degree with the vertical
