A tourist in ireland wants to visit seven different cities. if the route is randomly selected, what is the probability that the tourist will visit the cities in alphabetical order? round your answer to five decimal places.
Answers
n----------> number of cities
the probability that the tourist will visit the cities in alphabetical order is (1/n!)
P=(1/n!)
n!-------------> (7*6*5*4*3*2*1)=5040
therefore
1/5040=0.000198-----------> (five decimal places)--------> 0.00020 (0.020%)
the answer is 0.00020 (0.020%)
The probability that the tourist will visit the cities in alphabetical order is 0.00020.
There are a total of 7! ways to visit 7 different cities, but there is only one way to visit them in alphabetical order. So, the probability that the tourist will visit the cities in alphabetical order is:
1/7! = 1/5040 = 0.0002
To five decimal places, the probability is 0.00020.
Here is a step-by-step explanation of the calculation:
We can think of the route as a permutation of 7 letters, with no of the letters being identical.
The number of permutations of 7 letters is 7!.
So, the number of ways to visit the cities in alphabetical order is 1.
The probability that the tourist will visit the cities in alphabetical order is 1/7!.
Here are some additional things to consider:
The probability that the tourist will visit the cities in alphabetical order is very small, because there are many other possible routes.
The probability would be 1 if there were only one city to visit.
The probability would be 0 if there were 7 cities and the tourist had to visit them all in alphabetical order.

How much will it cost to mail a first-class letter that weighs 2.8 oz?
The rate is $.22 for the first ounce and $.17 for each additional
ounce or fraction of an ounce.
a. $.56
b. $5.60
c. $.53
d. $.39
Answers
Final answer:
The total cost to mail a first-class letter that weighs 2.8 oz is $0.56, which includes $0.22 for the first ounce and $0.34 for the additional weight.
Explanation:
To calculate the cost of mailing a first-class letter that weighs 2.8 oz, you need to know the initial rate for the first ounce and the rate for each additional ounce. According to the given rates, the cost for the first ounce is $0.22, and each additional ounce (or fraction thereof) costs $0.17.
Since the letter weighs 2.8 oz, you have 1.8 oz over the first ounce. Thus, you need to pay for 2 additional ounces.
The total cost = cost for first ounce + cost for additional ounces = $0.22 + 2 x $0.17 = $0.22 + $0.34 = $0.56. Therefore, the correct answer is (a) $.56.

What is Scale?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult. This change makes the idea of size significant in two different ways.
Given, An advertisement on a billboard measures 22 ft long and 8 ft high. If the ad is transferred to the side of a bus and is 30 ft. Long.
when the advertisement is 22 ft long then the height is 8 ft.
So,
When the advertisement is 1 ft long then the height is = 8/22 ft.
the advertisement is 1 ft long then the height is = 4/11 ft.
thus,
the advertisement is 30 ft long then the height is = 4/11 * 30 ft.
the advertisement is 30 ft long then the height is = 120/11 ft.
the advertisement is 30 ft long then the height is = 10 ft 11 inches.
Therefore, When the advertisement is 30 ft long then the height is 10 ft 11 inches.

Now we can simplify by combining like terms
72x - 9x = 63x
90 + 81 = 171

Frank is constructing the circumscribed circle for △XYZ. He has already used his compass and straightedge to complete the part of the construction shown in the figure.
Which construction could be his next step?
Place the point of the compass on point Y and draw an arc intersecting the two arcs.
Place the point of the compass on point X and draw an arc intersecting the two arcs.
Place the point of the compass on point Z and draw an arc through points X and Y.
Place the point of the compass on one of the arcs and draw an arc through point X.
Answers
the diagram already has arcs marked from point Y, with the aim of drawing a perpendicular bisector to line XY.
Therefore the next step is to place the compass on point X and draw two arcs which cross the arcs already drawn (second option is the correct answer)
The points at which the 2 arcs meet are connected to each other making a perpendicular bisector that would cut XY perpendicularly.
Next step is to place the compass at Z and draw 2 arcs between Z and Y points, similarly place the compass at Y and draw 2 arcs that would cut the arcs already drawn.
Then connect the two points where the arcs meet and thats the perpendicular bisector of ZY.
The point at which perpendicular bisectors of XY and YZ meet is known as the circumcenter. Place the compass on this point with the radius any of the three points X,Y or Z and draw the circle
Answer:
Place the point of the compass on point X and draw an arc intersecting the two arcs.
Step-by step explanation:
This is to complete the angle bisector.
Give the domain and range a. Domain: {-3, 0, 2}, range: {3, 0, -2} b.
Answers
The domain of a function is the set of all possible input values, while the range is the set of possible output values. In the given example, the function's domain is {-3, 0, 2}, which means the input data will be either -3, 0, or 2. Similarly, the function's range is {3, 0, -2}, which means the output data will be either 3, 0, or -2.
Explanation:In mathematics, the domain of a function refers to the set of all possible input values (often represented as 'x' values) that the function can accept without producing an undefined result. Similarly, the range of a function refers to the set of all possible output values (often represented as 'y' values) that the function can produce.
To address your examples: for a function with domain {-3, 0, 2} and range {3, 0, -2}, it means all input data ('x' values) will be either -3, 0, or 2; and all output data ('y' values) will be either 3, 0, or -2.

In GHI, HI = IHG =3x + 4, and IGH = 2x - 24. What is HIG?
Answers
<IGH = <HIG = 2x - 24
as you know sum of interior angles in a triangle = 180
so
2(2x - 24) + 3x + 4 = 180
4x - 48 + 3x + 4 = 180
7x - 44 = 180
7x = 224
x = 32

Answer:
The measure of angle YUV is equal to [tex]m<YUV=42\°[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we have that
[tex]arc\ UV=84\°[/tex] -----> given problem
so
[tex]m<UZV=84\°[/tex] ------> by central angle
we know that
The triangle UZV is an isosceles triangle
because
[tex]ZU=ZV=radius[/tex]
so
[tex]m<ZUV=m<ZVU[/tex] -----> bases angle of the isosceles triangle
Remember that
The sum of the internal angles of a triangle is equal to [tex]180\°[/tex]
so
[tex]m<ZUV+m<ZVU+m<UZV=180\°[/tex]
[tex]2m<ZUV+m<UZV=180\°[/tex]
substitute and solve for m<ZUV
[tex]2m<ZUV+84\°=180\°[/tex]
[tex]m<ZUV=(180\°-84\°)/2=48\°[/tex]
[tex]m<ZUV+m<YUV=90\°[/tex] ------> by complementary angles
