The table shows the results of a survey of 100 people selected at random at an airport. Find the experimental probability that a person selected at random is going to City B.
The experimental probability that a person selected at random is going to City B is __
Answers
Answer:
3/50
Step-by-step explanation:
The experimental probability that a person selected at random is going to City B is 19/50.
What is the experimental probability?Experimental probability is a probability that is determined on the basis of a series of experiments.
The table shows the results of a survey of 100 people selected at random at an airport.
The total number of responses is;
= 24 + 38 + 14 +22 +2
= 100
The experimental probability that a person selected at random is going to City B is given by;
[tex]\rm Probability =\dfrac{Responses \ from \ city \ B}{Total \ responses}\\\\ Probability =\dfrac{38}{100}\\\\ Probability =\dfrac{19}{50}[/tex]
Hence, the experimental probability that a person selected at random is going to City B is 19/50.

A triangle has sides that are 3, 7, and squareroot 57. Is the triangle a right triangle?
Answers
Answer:
my answer is no because for a right angle triangle the sum of the squares of the other two sides is equal to the square of the longest side
3²+7²=9+49=58
(√57)²=57
57≠58 it's not a right angle triangle
assume the sides to be a,b and c
a=3 b=7 c=√57
by Pythagoras theorem
a²+b²=c²
3²+7²=√57²

A square has an area of 313.29m2.
Work out the perimeter of the square.
Answers
The perimeter of the square is 70.8 meters.
To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².
The formula for the area of a square is:
Area = side length²
We can rearrange this formula to solve for the side length:
Side length = √Area
Substituting the given area into the formula, we have:
Side length = √313.29 m²
Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).
Since a square has four equal sides, the perimeter is simply four times the side length:
Perimeter = 4 * 17.7 m = 70.8 meters
As a result, the square's circumference is 70.8 metres.

For numbers 11-16 Find x, y, and z for each. Show all work.
Answers
Answer:
x=74
y=37
z=25
Step-by-step explanation:
First, we can find y.
106 and 2y are supplementary angles. That means that when added together, they equal 180.
106+2y=180
2y=74
y=37
We can use this information to help us find x.
x and 2y are corresponding angles, which means that they are congruent.
2y=x
2(37)=x
74=x
Now, let's find z.
4z+6 is corresponding to the angle right above angle x. This means that (4z+6)+x=180.
Let's solve.
(4z+6)+74=180
4z+80=180
4z=100
z=25

A horse's paddock is triangular with a height of 76 ft and sides of 114 ft, 102 ft, and 53 ft. What is the cost of fencing around the paddock if the fencing costs $5.40 per ft?
Answers
Answer:
$1452.6
Step-by-step explanation:
To obtain the cost of fencing round a triangular paddock, we obtain the perimeter. The perimeter of a triangle is given as :
Perimeter = a + b + c ; where a, b and c are the length of the three sides of the triangle.
The perimeter of the paddock in this scenario is :
(114 + 102 + 53) feets = 269 feets ; which are the lengths of the 3 sides of the triangular paddock.
Painting Cost per feet = $5.40
Cost per feet * number of feets
$5.40 * 269
= $1452.6

Write an equation for the nth term of each arithmetic sequence: 45, 30, 15, 0, …
Answers
Answer:
[tex]a_{n}[/tex] = 60 - 15n
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = a₂ - a₁ = 30 - 45 = - 15 , then
[tex]a_{n}[/tex] = 45 - 15(n - 1) = 45 - 15n + 15 = 60 - 15n
An equation for the nth term of the arithmetic sequence is aₙ=60-15n.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
The given arithmetic sequence is 45, 30, 15, 0,.....
Here, a=45 and d=30-45 = -15
Now, aₙ=45+(n-1)(-15)
aₙ=45-15n+15
aₙ=60-15n
Therefore, an equation for the nth term of the arithmetic sequence is aₙ=60-15n.
