The distance between the two points pictured is d= Vn

katrin [286]

the distance between points is:

d = 7.8 units

d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)

The ordered pairs are:

(x1, y1) = (- 3, -2)

(x2, y2) = (2,4)

By applying the formula we have:

d = root ((2 - (- 3)) ^ 2 + (4 - (- 2)) ^ 2)

d = root (61)

d = 7.8

Mean = $\frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}$

Mean = $\frac{134}{33}$

Mean = $4.06$
