X= n over a + r over a
(n over a being in a fraction. n being the numerator and a being the denominator)
i think this is right, not perfectly sure

Ax-n=r
ax=n+r
r= (r+n)/a

A committee has thirteen members. There are three members that currently serve as the board's chairman, ranking member, and tre

kogti [31]

Answer: Probability P = 1/1716

Step-by-step explanation:

Definition

For permutation ( order is important)

nPr = n!/(n-r)!

Given;

Total number of members in the committee = 13

Total number of members to be selected = 3

Since order is important in this case.

The total number (Tt) of possible ways of selecting three executives from the committee members is given as

Tt = 13P3 (since order is important)

Tt = 13!/(13-3)!

Tt = 13!/10!

Tt = 1716

The probability P of randomly selecting the three members who currently hold the positions of chairman, ranking member, and treasurer and reassigning them to their current positions is equal to

P = number of favourable outcomes/ number of possible outcomes

Number of favourable outcomes = 1 (i.e 1×1×1 = 1) one option for each post.

Number of possible outcomes = Tt = 1716

P = 1/1716

A jet can fly at a rate of 480 mi/h in calm air. Traveling with the wind, the plane flew 1560 mi in the same amount of time it t

slamgirl [31]

Let the Rate of the Wind be : W mi/h

Given : The Jet can fly at a rate of 480 mi/h

⇒ Travelling with the Wind, Jet flies with a speed of (480 + W) mi/h

⇒ Travelling against the Wind, Jet flies with a speed of (480 - W) mi/h

Given : The Jet Travels 1560 Miles, Travelling with the Wind

<u>Let us calculate How much time the Jet takes to Travel 1560 Miles</u>

In One Hour : The Jet travels a Distance of (480 + W) Miles

⇒ The Jet travels a Distance of 1560 Miles in : $[\frac{1560}{480 + W}]\;Hours$

Given : The Jet Travels 1320 Miles, Travelling against the Wind

<u>Let us calculate How much time the Jet takes to Travel 1320 Miles</u>

In One Hour : The Jet travels a Distance of (480 - W) Miles

⇒ The Jet travels a Distance of 1320 Miles in : $[\frac{1320}{480 - W}]\;Hours$

Given : Time taken to fly 1560 Miles with the Wind = Time taken to fly 1320 Miles against the Wind.

⇒ $\frac{1560}{480 + W} = \frac{1320}{480 - W}$

⇒ 1560(480 - W) = 1320(480 + W)

⇒ (1560 × 480) - 1560W = (1320 × 480) + 1320W

⇒ 1560W + 1320W = (1560 × 480) - (1320 × 480)

⇒ 2880W = 480(240)

⇒ 288W = 48(240)

⇒ 72W = 12(240)

⇒ 6W = 240

⇒ W = 40

⇒ The Rate of Wind is 40 mi/h
