The newest teacher, Valerie, decides to teach part-time which decreases her salary from \$40{,}000$40,000dollar sign, 40, comma, 000 to \$20{,}000$20,000dollar sign, 20, comma, 000 per year. The rest of the salaries stay the same. How will decreasing Valerie's salary affect the mean and median?

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
