Her scores would be 98, 82, and 81. Their sum would be 261 then you would divide it be 3 and it would give you 87 then to find the median line the numbers up from greatest to least and 82 would be in the middle. To find the range subtract 81 from 98 and it gives you 17. Did this help?
To find how much cinnamon per pound you first divide the $2.40 by the 3 oz to find how much per ounce...so $2.40/3 = 80 cents. Then u multiply that by the 16 oz to get the amount for 1 pound...so .80x16= $12.80 per pound.
Hope it helps!
[1] -5y + 8x = -18
[2] 5y + 2x = 58
Solution:
As 360°= 2 π Radian
1 Radian =
1. Sin(-1)= Sin (
)
= Sin (-57°16'22")=-0.84147
2.
=
(229°54'32")
=75.963757 Degrees
3. 
= 
(5°43'38")
= 84.26083 Degrees
