Answer:
D) 20,800,000
Step-by-step explanation:
Using the concept of standard deviation, it is found that the standard deviation of the data-set will remain the same.
-----------------------------------
- The mean of a data-set is given by the <u>sum of it's observations, divided by the number of observations</u>.
- The standard deviation is given by the <u>square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values</u>.
- If all observations are increased by a value x, the mean will also increase by x.
- In the standard deviation, at the sum of the differences squared of each observation and the mean, each observation is increased by x, as is the mean, thus, the sum stays the same, while the standard deviation also stays the same.

Answer:
Sydney is 45
Step-by-step explanation:
Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...
s +(s -14) = 76
2s = 90 . . . . . . simplify, add 14
s = 45 . . . . . . . divide by 2
Sydney's age is 45.
___
<em>Check</em>
Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.
I believe the correct answer is 365,000, since the double of those 40% is 292,000 (80%), and to find the remaining 20% you just divide 40% in half to get 73,000, adding that to 292,000 will get you 365,000, hope o helped !
