Answer:
log(0.0003) = -3.5229
Step-by-step explanation:
The rules of logarithms tell you ...
log(ab) = log(a) +log(b)
<h3>Application</h3>
log(0.0003) = log(3×10^-4) = log(3) +log(10^-4)
= log(3) -4 = 0.4771 -4
log(0.0003) = -3.5229

<em>Additional comment</em>
If you do much work with logarithms, you find that negative logarithms are generally expressed using a positive mantissa with a negative add-on. Often, that negative add-on is -9, so this would be ...
5.4771-9
This helps when taking antilogs, as you look up 0.4771 in the table to see that the multiplier is 3.
If you were to look up 0.5229, you would find 3.333, meaning the multiplier is 1/3.333 and the antilog of -3.5229 is (10^-3)/3.333. This may not be a convenient value to work with.
Answer:
Find out the what is the slope of the line that passes through the points (-3, 5) and (1, 7) .
To prove
Formula for slope
The points are (-3, 5) and (1, 7) .
Put in the formula
Simplify the above
Option (A) is correct .
To find the mean we add up all the values then divide by the amount of the terms so (150+330+690+245)/4
1415/4
the mean is: 353.8

Answer:
The test statistic is and the observed value 1.68
Step-by-step explanation:
We have a large sample size n = 100, the point estimate for the true proportion of overfilled bags p is given by . The test statistic is given by which is distributed as a standard normal variable approximately because we have a large sample. The observed value for the test statistic in this case is
