How do you find values of pro-numerals ?

Mathematics

Answer:

pronumeral is a letter that is used to represent a number (or numeral) in a problem.

For example, the formula for the area of a rectangle is:

Area of a rectangle = length × width

If A represents the area of the rectangle, l represents the length of the rectangle and w represents the width of the rectangle, then we can write the formula for the area of the rectangle as follows:

A = l × w

In this formula, the letters A, l and w are called pronumerals.

Note:

A pronumeral is a letter used in a problem to represent the measurement of a quantity.  We often choose the first letter of the name of a quantity.

For example, the measurement of the base of a triangle will be represented by b.

Please note: The input of a ⇒ 7 will not apply the value to the pronumeral.

Now we can use a in our calculations

Furthermore, a can be used with a defined function:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Bob has a standard deck of playing cards. If he randomly draws a J, K, 2, and 2, what is the probability that the next card he d
nlexa [21]

Answer:

The correct answer has already been given (twice). I'd like to present two solutions that expand on (and explain more completely) the reasoning of the ones already given.


One is using the hypergeometric distribution, which is meant exactly for the type of problem you describe (sampling without replacement):


P(X=k)=(Kk)(N−Kn−k)(Nn)


where N is the total number of cards in the deck, K is the total number of ace cards in the deck, k is the number of ace cards you intend to select, and n is the number of cards overall that you intend to select.


P(X=2)=(42)(480)(522)


P(X=2)=61326=1221


In essence, this would give you the number of possible combinations of drawing two of the four ace cards in the deck (6, already enumerated by Ravish) over the number of possible combinations of drawing any two cards out of the 52 in the deck (1326). This is the way Ravish chose to solve the problem.


Another way is using simple probabilities and combinations:


P(X=2)=(4C1∗152)∗(3C1∗151)


P(X=2)=452∗351=1221


The chance of picking an ace for the first time (same as the chance of picking any card for the first time) is 1/52, multiplied by the number of ways you can pick one of the four aces in the deck, 4C1. This probability is multiplied by the probability of picking a card for the second time (1/51) times the number of ways to get one of the three remaining aces (3C1). This is the way Larry chose to solve the this.

PLS Help Asap! i will award brainliest On her way to her grandmother's house, Jackie traveled three times as many miles by train
nirvana33 [79]

Answer:

24 miles.

Step-by-step explanation:

Jackie traveled four times as many miles by bus as by foot. This means that the number of miles travelled by bus is 4 units, and the number of miles travelled by foot is 1 unit.

Jackie traveled three times as many miles by train as by bus. We know that the number of miles travelled by bus is 4 units, so the number of miles travelled by train is 4\times3=12 units.

Total number of units: 12units+4units+1unit=17units

17units=34

Divide 17:

1 unit=2

The number of miles travelled by train is 12 units:

12units=2\times 12=24

She travelled 24 miles by train.
