There are $9C_3$ ways to select 3 from 9.

There are $5C_3$ ways to select 3 men from 5 men and $4C_3$ ways to select 3 women from 4 women.

If all three selected are men, then no woman was selected, and we have

$5C_3 \times 4C_0$ ways we can do that.

$P(All -3 -are -men)=[tex]\frac{5C_3 \times 4C_0}{9C_3}=\frac{5}{42}$

2) If all 3 are women then no man was selected, and we have

$5C_0 \times 4C_3$ ways we can do that.

$P(All- 3- are- women)=\frac{5C_0 \times 4C_3}{9C_3}=\frac{1}{21}$

3) If 2 men and 1 woman were selected, the we have $5C_2\times 4C_1$ ways we can do that.

$P(2 -men -1 -woman)=\frac{5C_2\times 4C_1}{9C_3}=\frac{10}{21}$

4) If 2 women and 1 man is selected, then we have $5C_1 \times 4C_2$

$P(2- women- 1 -man)=\frac{5C_1\times 4C_2}{9C_3}=\frac{5}{14}$

Using triangle A B C as the pre-image and the origin as the center of dilation, which coordinate point is not a coordinate of a

Ostrovityanka [42]

Answer:

The correct option is:

begin ordered pair 4 comma 12 end ordered pair i.e. (4,12).

Step-by-step explanation:

We are given the coordinates of the point A,B and C of the triangle ΔABC as:

A(-1,3) , B(2,1) and C(-2,-1).

Now it is given that there is dilation of this triangle about the origin with a scale factor of 4.

This means that the change in the coordinates after the transformation is given by the rule:

(x,y) → (4x,4y)

As A → A' , B → B' and C → C'

Hence the coordinates A',B' and C' are given by:

A' are (4×-1,4×3)=(-4,12)

B' are (4×2,4×1)=(8,4)

and C' are (4×-2,4×-1)=(-8,-4).

<em>Hence the coordinate point which is not a coordinate of dilation is:</em>

<em>begin ordered pair 4 comma 12 end ordered pair i.e. (4,12)</em>
