Answer:

(x-1) /2x

Step-by-step explanation:

(1-1/x)/2

(1 - 1/x) ÷ 2

copy dot flip for the division

(1 - 1/x) * 1/2

Getting a common denominator in the parentheses

(x-1)/x *1/2

Answer:

(x − 1) / (2x)

Step-by-step explanation:

I assume you mean (1 − (1/x)) / 2.

Find the common denominator of 1 and 1/x.

((x/x) − (1/x)) / 2

((x − 1) / x) / 2

Multiply by the reciprocal of 2.

((x − 1) / x) × (1/2)

(x − 1) / (2x)

Mary beth is making 7,763 millilters of punch she uses 3liters 26 millilters of orange juice how many liters of pinapple juice d

AlladinOne [14]

Answer:

<h3> 4.737 litres</h3>

Step-by-step explanation:

Total volume of punch beth is making = 7,763milliliters

If the punch contains the mixture of orange juice and pineapple juice then;

Volume of punch = Volume of pineapple juice + volume of orange juice

If she uses 3 litres 26 millilitres of orange juice.

converting the volume of orange juice to millilitres (1 litre = 1000 millilitres)

Volume of orange juice = 3000 millilitres + 26 millilitres = 3,026 millilitres

Volume of pineapple juice needed = Total volume of punch - Volume of orange juice

Volume of pineapple juice needed = 7,763 - 3,026

Volume of pineapple juice needed = 4,737millilitres

Converting the volume of pineapple to litres = 4,737/1000 = 4.737litres

The amount of liters of pineapple juice mary beth need to add to complete her punch is 4.737 litres

You have a six-sided die that you roll once. Let Ri denote the event that the roll is i. Let G j denote the event that the roll

Misha Larkins [42]

Answer:

a. $P (R3 | G1)=\frac{1}{5}$

b. $P (R6| G3)= \frac{1}{3}$

c. $P(G3|E)=\frac{2}{3}$

d. $P (E|G3)=\frac{2}{3}$

Step-by-step explanation:

The sample space associated with the random experiment of throwing a dice is is the equiprobable space {R1, R2, R3, R4, R5, R6}. Then,

a. The conditional probability that 3 is rolled given that the roll is greater than 1? $P (R3 | G1) = \frac{P (R3\bigcap G1)}{P(G1)} = \frac{1/6}{5/6} = \frac{1}{5}$

b. What is the conditional probability that 6 is rolled given that the roll is greater than 3? $P (R6| G3) = \frac{P (R6\bigcap G3)}{P(G3)} = \frac{1/6}{3/6} = \frac{1}{3}$

c. What is P [GIE], the conditional probability that the roll is greater than 3 given that the roll is even? $P(G3|E) = \frac{P (G3\bigcap E)}{P(E)} = \frac{2/6}{3/6} = \frac{2}{3}$

d. Given that the roll is greater than 3, what is the conditional probability that the roll is even? $P (E|G3) = \frac{P (E\bigcap G3)}{P(G3)} = \frac{2/6}{3/6} = \frac{2}{3}$

Help me with number 10 pleaseeeeeeeeee

valina [46]

Answer:

4' - 9.64

Step-by-step explanation:

Total rise = 2' - 7"

Total run = 3' - 9"

Converting to inches :

1' = 12" ; 1 feet = 12 inches

2' = 2 * 12 = 24"

3' = 3 * 12 = 36"

Total rise = 24" + 7" = 31"

Total run = 36" + 9" = 45"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(31² + 45²)

Hypotenus = 54.644304"

= 4' - 9.64"
