Math, 7th grade. Using the results from parts D through G, write an expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War. Write the expression in terms of c and w. Then solve the expression to find out how many years separate these two events.

D= Yes, I think the same. I think this because they're the same expression just different numbers.

E= The Civil War ended in 1865.

F= The expression in terms of w to represent the year of Helike’s disappearance is -1/5w.
Let w represent the year the Civil War ended.
The year the Greek city of Helike disappeared is -1/5 times the year the US Civil War ended.
The year the Greek city of Helike disappeared =
The expression in terms of w to represent the year of Helike’s disappearance = -1/5w

G= The year Helike disappeared was 373 BC.
1/5 times 1865
1/5 = 0.2 (As a decimal)
1865 times 0.2 = 373
Since it is not negative, (What it would be as a negative (-373)), It is BC
So the answer is 373 BC.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
