The answer choice that correctly calculates and interprets the standard deviation of the sum, S = X + Y is D. Sigma Subscript s = 0.8; companies A and B can expect the total weight of packages to vary by approximately 0.8 ounces from the mean.
<h3>What does the standard deviation means?</h3>
A standard deviation means the all measure of how dispersed the data is in relation to the mean. It should be noted that low standard deviation means that the data are clustered around the mean, and the high standard deviation means that the data are more spread out.
In this case, the answer choice that correctly calculates and interprets the standard deviation of the sum, S = X + Y is the sigma Subscript s = 0.8; companies A and B can expect the total weight of packages to vary by approximately 0.8 ounces from the mean.
In conclusion, the correct option is D.

Here is the answer OwO:
A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.
Here is the explanation/work OwO:
<u><em>Switch sides.</em></u>
c^2=12^2+9^2
<u><em>12^2=144</em></u>
c^2=144+9^2
<u><em>9^2=81</em></u>
c^2=144+81
<u><em>Add the numbers: 144 + 81 = 225</em></u>
c^2=225
<u><em>For x^2 = f(a) the solution is √f(a)</em></u>
c = 15
Therefore, your answer will be 15.
