Answer:
10
Step-by-step explanation:
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.

Answer:
x +4
Step-by-step explanation:
The trinomial x² +8x +16 is a perfect square trinomial, so factors as ...
x² +8x +16 = (x +4)²
Assuming the side length is one of the factors of the given area, it will be ...
side length = (x +4)
Answer:
$270
Step-by-step explanation:
We are given;
- The rate of increase is 8%
- The new amount is $250
We need to determine the value in the next year with the same rate of increase;
Therefore;
250% = 100%
New amount = 100 + 8 = 108%
Therefore;
New amount = (250 × 108)÷ 100
= $270
Therefore, the value in the next year is $270
