The probability of first drawing a red card, then a jack, and then a black card is 0.0612
First we will describe the standard deck of 52 cards in terms of black, red and face cards found in a standard deck
Following is a table of distribution of colored and face card found in a standard deck:
Type Number of cards
1 - 10 40
Black 26
Red 26
Face 12
The numerical cards from digit ( 1 to 10 ) are found in all 4 suits ( Clubs, Diamonds, Spades, and Hearts ). Hence, 10 x 4 = 40
- The entire deck is split in two colors ( Red and Black ) equally. So, the number of Black and Red cards are = 52 / 2 = 26 cards.
- The face cards are of three types ( King, Queen and Jack ). These three face cards are found in each of the 4 suits. Hence, Total number of face cards are = 4 * 3 = 12
- We will now consider the probabilities associated with each type. We will define 3 events and write down their probability as expressed:
Event ( A ): First draw is a red card.
- The probability of this event can be determined with the help of the table given above. There are a total of 26 red card in a standard deck of 52 cards. Hence,
p ( A ) = [ Number of red cards ] / [ Total cards in a deck ]
p ( A ) = [ 26 ] / [ 52 ]
p ( A ) = 1 / 2
- After we make the first draw of a red card. Our deck distribution is changed to Number of Red cards remaining = 25 and total deck now has 51 cards remaining.
- We will define the next event as:
Event ( B ): The second draw is a face card.
- The probability of this event can be determined with the help of the table given above. There are a total of 12 face cards in a standard deck of 52 cards which is now down to 51 cards. Hence,
p ( B ) = [ Number of face cards ] / [ Total cards in a deck ]
p ( B ) = [ 12 ] / [ 51 ]
p ( B ) = 4 / 17
- After we make the first draw of a face card. Our deck distribution is changed to Number of Face cards remaining = 11 and total deck now has 50 cards remaining.
- We will define the next event as:
Event ( C ): The third draw is a black card.
- The probability of this event can be determined with the help of the table given above. There are a total of 26 black cards in the deck. The total number of cards are down to 50 cards only. Therefore,
p ( C ) = [ Number of black cards ] / [ Total cards in a deck ]
p ( C ) = [ 26 ] / [ 50 ]
p ( C ) = 13 / 25
- The entire drawing process consists of 3 events which are dependent on each draw. However, for the overall event to occur i.e drawing a red card , then a face card, and then a black card. We will multiply all three outcomes as follows:
p ( T ) = p ( A ) * p ( B ) * p ( C )
p ( T ) = [ 1 / 2 ] * [ 4 / 17 ] * [ 13 / 25 ]
p ( T ) = [ 26 / 425 ] ≈ 0.0612
Hence we get the required answer.

Step-by-step explanation:
Horizontal lines are parallel so as suggested in:
1. Vertical angles are congruent, so 5a = 115.
2. Alternate interior angles are congruent, so b - 12 = 65.
3. Corresponding angles are congruent and linear angle pairs sum up to 180, so (b-12) + 65 = 180.
However, alternate interior angles are congruent,
as stated in 2nd suggestion too, so the sum is not 180 but 130.
Therefore 4th suggestion is not correct.
A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (-5, 0) and goes to point (-5, 5) to fish. From
there, the boat travels to (0, 0) to fish and then goes back to the launch point
Determine the total number of miles traveled. Round to the nearest whole number.
05 miles
07 miles
O17 miles
O50 miles
The total number of miles traveled is given by the following option:
17 miles.
How to obtain the total distance?The total distance is divided into three parts, obtained as follows:
First part: From point (-5,0) to point (-5,5).Second part: From point (-5,5) to point (0,0).Third part: From point (0,0) back to the launch point of (-5,0).The generic notation of two points is given as follows:
[tex](x_1,y_1), (x_2,y_2)[/tex]
The distance between two points is then given by the equation presented as follows:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence each distance in this problem is given as follows:
First part: 5 miles.Second part: 7 miles.Third part: 5 miles.The total distance is the sum of each distance, hence it is given as follows:
5 miles + 7 miles + 5 miles = 17 miles.
Hence the third option is correct.

What is compounding interest?
Compound interest is interest calculated on the initial principal, that conjointly includes all of the accumulated interest from previous periods.
Generating "interest on interest" is thought because the power of interest.
Main body:
1)

How to use the Law of Indices?
We want to find the expression that is equivalent to the quantity nine raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power. Indices display the results of multiples of a number, such as squared or cubed, or they display the roots of numbers, such as the square root. The laws of indices can be used to condense some indexed terms.This is written as;
(9⁻² * 3⁵)⁻²
According to laws of indices, we know that;
(a²)³ = a²*³ = a⁶

What is permutation and combination?
The process of placing all the components of a set into a certain sequence or order is known as permutation in mathematics. In other terms, the process of permuting is the reordering of the components of a set if the set is already ordered. Nearly all areas of mathematics involve permutations in some form or another. They frequently appear when various orderings on particular finite sets are taken into account.The combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection or k-combination with repetition are often used.[tex]$11xy,\qquad 1x1y,\qquad1xy1$[/tex]
Because the number must have exactly two identical number digits,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. Hence, there are [tex]$3\cdot9\cdot8=216$[/tex] number of this form.
Now suppose that the two identical digits are not 1. Reasoning similarly to before, we have the following possible combination:

Again,,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. There are [tex]$3\cdot9\cdot8=216$[/tex] numbers of this form.

The number of men on the sight - seeing tour was 22 .
In the question ,
it is given that,
the ratio of women to children on the tour is = 5 : 2
let the number of men in the sight seeing tour = m
let the number of women in the sight seeing tour = w
let the number of children in the sight seeing tour = c
So , w/c = 5x/2x
also the ratio of children to men is 5/11 ,
c = 5y and m = 11y
the number of women on the sight seeing tour is less than 30 ,
which is 5x < 30 ,
x < 6
but we have c = 2x and 5y ,
and since c is a multiple of 5 , 2x also has to be a multiple of 5 ,
earlier we got , x < 6 ,
Now using x =5 , we get c = 2*5 = 10
and so , 10 = 5y
y = 2 ,
So , the number of men = 11y = 11*2 = 22 men
Therefore , the number of men are 22 .

The length of a rectangular poster is 2 more inches than three times its width. The area of the poster is 161 square inches. Solve for the dimensions (length and width) of the poster.
The length and width of the rectangular poster are 23 inches and 7 inches respectively.
Here we have to find the dimensions of the length and width of the rectangular.
Data given:
length of the rectangular poster is 2 more than three times its width.
Let us assume that the width of the rectangular is x.
The area of the poster = is 161 inches²
So by this, we get the length 3x + 2.
width = x
length = 3x + 2
The formula of the area of the rectangular:
Area = length × width
161 = (3x+ 2) × x
161 = 3x² + 2x
3x² + 2x - 161 = 0
3x² + 23x - 21x - 161 = 0
x(3x + 23) - 7( 3x + 23) = 0
(3x + 23) ( x -7)= 0
x = -23/3, 7
As the length cannot be negative so we get the value of x as 7
width = 7 inches
length = 3x + 2
= 3×7 + 2
= 21 + 2

Determine the ratio of the geometric sequence: 1/16, -1/4, 1,...
Answer:
The common ratio of the given sequence is - 4-------------------------------
Given sequence:
1/16, - 1/4, 1, ...Find the common ratio, the ratio of two consecutive terms:
r = 1 ÷ (- 1/4) = 1 × (- 4) = - 4or
r = - 1/4 ÷ 1/16 = - 1/4 × 16 = - 4
