Answer:

C. The difference of the medians is 4 times the interquartile range.

Step-by-step explanation:

The diagram show two box plots.

<u>Mahoney's box plot:</u>

Median $=33$

Interquartile range $=34-32=2$

<u>Martin's box plot:</u>

Median $=41$

Interquartile range $=42-40=2$

The interquartile ranges are the same.

The difference of the medians $=41-33=8$

Hence, the difference of the medians is 4 times the interquartile range.

The coordinates of the point 3/10 of the way from A to B are

nikitadnepr [17]

Answer:

(0, - $\frac{32}{13}$ )

Step-by-step explanation:

If a point (x, y) that divides a line segment having extreme ends $(x_1,y_1)$ and $(x_2,y_2)$ into the ratio of m : n,

x = $\frac{mx_2+nx_1}{m+n}$

and y = $\frac{my_2+ny_1}{m+n}$

From the picture attached,

Extreme ends of a segment are A(-3, -5) and B(10, 6).

Let a point (x, y) divides this segment divides this segment in the ratio of 3 : 10,

x = $\frac{3\times 10+10\times (-3)}{3+10}$

= 0

y = $\frac{3(6)+10(-5)}{3+10}$

= $\frac{18-50}{13}$

= $-\frac{32}{13}$

Therefore, $(0,-\frac{32}{13})$ is a point which divides AB in the ratio of 3 : 10.
