Answer:
b = 1.52
Step-by-step explanation:
Length of diagonals of a parallelogram = 
and 
If the given parallelogram is a rectangle,
Length of the diagonals will be equal in measure,
Therefore, 
245b - 365 = 
245b - 365 = 
5(245b - 365) = 4(3b + 6)
1225b - 1825 = 12b + 24
1225b - 12b = 24 + 1825
1213b = 1849
b = 
b = 1.52
6.213 as a mixed number would be 6 and 213/1000.
all you do to convert it to a mixed number is look at how many numbers are after the decimal.
since theres 3 numbers, that means it would be in the thousands place
I think the answer is 9.375 if it needs to be in decimal form. If it needs to be in fraction form it would be improper, 9 3/8 would be the fraction. Hope it helps!
It can't be A. since if you only look at managers, you are missing all the sales executives.
It may be C. this option is more random but doesn't guarantee that you will represent both groups of employee's. Also, each time you would conduct the survey, you will receive the exact same results since it is the same people.
It isn't D. for the exact same reason as A. but you're missing managers now.
Therefore the answer is B. Some managers and some sales executives selected at random. This way you get a sample from both categories, and within those groups, it is randomly selected.
I hope this helps!
