Answer:
m+n=23
Step-by-step explanation:
the modes m and n have to be data points more than 1 time, but equal
if there are 7 data points, then there are 4 unknown left/2 2 each
(2m-3+m+12+3n+2+m+m+n+n)/7=18
(3m+9+3n+2+m+m+n+n)/7=18
(5m+5n+11)/7=18
(5/7)*m+(5/7)*n+11/7=126/7
(5/7)*m+(5/7)*n=115/7
5m+5n=115
m+n=115/5
m+n=23
Answer:
-3.8
Step-by-step explanation:
-3.8+7.2=3.4
X = 250 mg tabs
y = 500 mg tabs
2200x + 1800y = 39200....multiply by -1
2200x + 2200y = 44000
--------------------------------
-2200x - 1800y = - 39200 (result of multiplying by -1)
2200x + 2200y = 44000
--------------------------------add
400y = 4800
y = 4800/400
y = 12...... the 500 mg tabs (y) costs $ 12 per bottle
2200x + 2200y = 44000
2200x + 2200(12) = 44000
2200x + 26400 = 44000
2200x = 44000 - 26400
2200x = 17600
x = 17600/2200
x = 8 <== the 250 mg tabs (x) costs $ 8 per bottle
