The distance between points $P_1(x_1,y_1)$ and $P_2(x_2,y_2)$ can be calculated using formula

$P_1P_2=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.$

1.

$AB=\sqrt{(-7-(-11))^2+(8-4)^2}=\sqrt{16+16}=\sqrt{32}=4\sqrt{2}\approx 5.657.$

2.

$AC=\sqrt{(-4-(-11))^2+(4-4)^2}=\sqrt{49+0}=\sqrt{49}=7.$

3.

$CB=\sqrt{(-7-(-4))^2+(8-4)^2}=\sqrt{9+16}=\sqrt{25}=5.$

Then

$P_{ABC}=5.657+7+5=17.657\approx 17.7$

From families with four children a family is chosen at random. Let X be the number of boys in the family. Calculate and sketch t

alisha [4.7K]

Solution :

Given :

X = the number of boys in a family of four children

Families having four children are chosen randomly.

The gender distribution in the four child family are equally probable.

Thus,

X P(X) CDF

0 $^4C_0 (1/2)^{4}$ = 1/16 $\frac{1}{16}$

1 $^4C_1 (1/2)^{4}$ = 1/4 $\frac{5}{16}$

2 $^4C_2 (1/2)^{4}$ = 3/8 $\frac{11}{16}$

3 $^4C_3 (1/2)^{4}$ = 1/4 $\frac{15}{16}$

4 $^4C_4 (1/2)^{4}$ = 1/16 1
