Point B lies between points A and C on Line segment A C . Let x represent the length of segment AB in inches. The length of line

olchik [2.2K]

Step-by-step explanation:

If Point B lies between points A and C on line segment AC, then the formula is true AB+BC = AC

Given

AB = x inches'

AC = 20 inches

BC = 3x

Substituting the given parameters into the formula AB+BC = AC

x + 3x = 20

4x = 20

Divide both side by 4

4x/4 = 20/4

x = 5

Since x = 5 inches, hence the segment AB id 5 inches.

Given BC = 3x

BC = 3(5)

BC = 15 inches

This means that the space between points A and B is labeled 5 inches while the space between points B and C is labeled 15 inches.

Answer: PQR=32

Step-by-step explanation:

RQS+PQR=PQS

(4x+4)+(3x-1)=80

7x+3=80

7x=77

x=11

PQR=(3x-1)=> (3(11)-1) => 33-1=32

A person bets 1 dollar to b dollars that he can draw two cards from an ordinary deck of cards without replacement and that they

sertanlavr [38]

Answer:

$3.25

Step-by-step explanation:

In an ordinary deck of cards, we will notice that there are 52 cards.

However, we have 4 suits and 13 cards in each one making a total of 52, right?.

So, the probability that a person draws two cards and they will be of the same suit is:

$P(X) =\dfrac{ \bigg (^4_1 \bigg) \times \bigg ( ^{13}_{2}\bigg) }{ \bigg ( ^{52}_{2} \bigg)}$

$P(X) =\dfrac{ \dfrac{4!}{1!(4-1)!} \times \dfrac{13!}{2!(13-2)!} }{ \dfrac{52!}{2!(52-2)!} }$

$P(X) =\dfrac{4}{17}$

Given that; A person bets 1 dollar to b dollars;

To make the bet fair is;

$\dfrac{4}{17}b - \dfrac{13}{17}(1) = 0$

$= \dfrac{4}{17}b = \dfrac{13}{17}$

multiply both sides by 17

4b = 13

b = 13/4

b = 3.25

Therefore, to make the fair, the value of b need to be $3.25
