Answer:
The answer to your question is: [tex][ 4\frac{1}{8} , -3][/tex]
Step-by-step explanation:
Data
H [tex][ 5\frac{1}{2} , -4\frac{3}{4} ][/tex]
X [tex][2\frac{3}{4} , -1\frac{1}{4} ][/tex]
Process
Xm = [tex][5\frac{1}{2} + 2\frac{3}{4} ] / 2[/tex]
Xm = [tex][\frac{11}{2} + \frac{11}{4} ] / 2[/tex]
Xm = [tex][\frac{22}{4} + \frac{11}{4}] / 2[/tex]
Xm = [tex][\frac{33}{4} ] / 2[/tex]
Xm = [tex]\frac{33}{8}[/tex]
Xm = [tex]4 \frac{1}{8}[/tex]
Ym = [tex][ -4\frac{3}{4} - 1\frac{1}{4} ] / 2[/tex]
Ym = [tex][ -\frac{19}{4} - \frac{5}{4}] / 2[/tex]
Ym = [tex][- \frac{24}{4} ] / 2[/tex]
Ym = [tex]- \frac{24}{8}[/tex]
Ym = - 3
[tex][ 4\frac{1}{8} , -3][/tex]
