Sagot :

ANSWER

1) The plot looks like the fulcrum would balance at point 4

After calculation, the mean is 4.

2) The plot looks like the fulcrum would balance at point 3;

After calculation, the mean is 3.8.

3) The plot looks like the fulcrum would balance at point 8;

After calculation, the mean is 7.2

EXPLANATION

From the given data;

1) The plot looks like the fulcrum would balance at point 4.

the mean

[tex]\begin{gathered} mean(x)=\frac{(2+2+2)+(7+7)}{5} \\ =\frac{20}{5} \\ =4 \end{gathered}[/tex]

2) The plot looks like the fulcrum would balance at point 2;

The mean;

[tex]\begin{gathered} x=\frac{0+1+1+2+2+2+3+3+4+10}{10} \\ =\frac{38}{10} \\ =3.8 \end{gathered}[/tex]

3) The plot looks like the fulcrum would balance at point 8;

[tex]\begin{gathered} x=\frac{0+6+7+7+8+8+8+9+9+10}{10} \\ =\frac{72}{10} \\ =7.2 \end{gathered}[/tex]
