Weighted Mean (text p. 64-65) The following is a listing of raw material purchases by Acme Manufacturing over the past year: Purchase Cost Per Pound $ Number of Pounds 1 3.00 1200 2 3.40 500 3 2.80 2750 4 2.90 1000 5 3.25 800 Your boss wants you to calculate the mean cost of these raw materials. You could calculate the mean (arithmetic) by adding the five dollar amounts and dividing by 5 to get $3.07 per pound mean cost. However, this would not be the correct answer because you failed to account for the weighting (the number of pounds purchased at each price). Calculate the correct mean value for your boss by figuring the weighted mean cost per pound of this set of purchases:

∠cbe and ∠deb are same-side interior angles.

i took the test

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)

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
