Question

Using the computer output, the best estimate of the light intensity at 19 centimeters is:

a) 0.0876, because 0.8561 − 1.4966(log 19) = −1.058, and 10−1.058=0.0876 lumens.
b) 0.3472, because 0.8561 − 1.4966(log 19) = −1.058, and e−1.058=0.3472 lumens.
c) 0.3964, because 0.8561(log 19) − 1.4966 = −0.4018, and 10−0.4018=0.3964 lumens.
d) 0.6691, because 0.8561(log 19) − 1.4966 = −0.4018, and e−0.4018=0.6691 lumens.

Answer 1

The best estimate of the light intensity at 19 centimeters is 0.0876 lumens.

Step-by-step explanation:

The best estimate of the light intensity at 19 centimeters can be found using the given computer output. We need to use the formula 0.8561 - 1.4966(log 19). Let's calculate the value:

0.8561 - 1.4966(log 19) = -1.058

Now, we can use either 10^(-1.058) or e^(-1.058) to find the value in lumens. Since 10^(-1.058) is equal to 0.0876 lumens, the correct answer is option a) 0.0876.
