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

amm1812

Answer:

$(4, -3 )$

General Formulas and Concepts:

Pre-Algebra I

Order of Operations: BPEMDAS

Algebra I

Midpoint Formula: $(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )$

Step-by-step explanation:

Step 1: Define

R (9, 3)

S (-1, -9)

Step 2: Find midpoint

Substitute: $(\frac{9-1}{2}, \frac{3-9}{2} )$
Subtract: $(\frac{8}{2}, \frac{-6}{2} )$
Divide: $(4, -3 )$

PLEASE HELP FIND THE LENGTH OF RS.

Gwar [14]

Answer:

Step-by-step explanation:

Distance between 2 points

$= \sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} }$

☆ (x₁, y₁) is the first coordinate while (x₂, y₂) I'd the second coordinate.

Length of RS

$= \sqrt{ {[ - 1 -( - 4)] }^{2} + (9 - 1)^{2} } \\ = \sqrt{( - 1 + 4)^{2} + 8^{2} } \\ = \sqrt{ {3}^{2} + 64 } \\ = \sqrt{73} \\ = 8.54 \: (3 \: s.f.)$

Thus, RS is about 8.5 units.
