(b) 12 friends travel to the festival.
5 travel by car, 4 travel by bus and 3 travel by train.
Two people are chosen at random from the 12 friends.
Calculate the probability that they travel by different types of transport.
The probability that they two people are chosen and travel by different transport is 47/144
What is Probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
Probability is given as sample space / total outcome
Probability to travel by car p(C)= 5/12
Probability to travel by bus P(B)= 4/12=1/3
Probability to travel by train P(T)= 3/12= 1/4
for two people chosen at random
P(C ×B)= 5/12×1/3= 5/36
P(B×T)= 1/3×1/4= 1/12
P(C×T)= 1/4×5/12= 5/48
Therefore the probability that the two chosen travel by different car is
P(C ×B)+P(B×T)+P(C×T)= 5/36+1/12+5/48
= 141/432

ordered pairs solution for 7x+2y>-26
The ordered pairs that are solutions of the inequality are of the form:
(x, y > -3.5*x - 13)
Which ordered pairs are solutions of the inequality?
Here we have the inequality:
7x + 2y > -26
The solutions of this are the pairs (x, y) that, when replaced on the inequality, make it true.
If we isolate y on the inequality we get:
7x + 2y > -26
2y > - 26 - 7x
y > (-26 - 7x)/2
y > -3.5*x - 13
Then the ordered pairs are of the form:
(x, y > -3.5*x - 13)
For example, suppose that we fix the value of x in 0, then:
y > -3.5*0 - 13
y > -13
So the points of the form (0, y > -13) are solutions.

Find three consecutive even integers such that the sum of the least integer and the middle integer is 24 more than the greatest integer.
Answer:
26, 28, 30
Step-by-step explanation:
there is a difference of 2 between consecutive even integers
let the integers be n , n + 2 , n + 4 , then
n + n+ 2 = n + 4 + 24
2n + 2 = n + 28 ( subtract n from both sides )
n + 2 = 28 ( subtract 2 from both sides )
n = 26
n + 2 = 26 + 2 = 28
n + 4 = 26 + 4 = 30
the 3 consecutive even integers are 26 , 28 , 30

After 15 years, Zephan will have a balance of $13181.07 in his savings account.
Given,
In the question:
Compound Interest is given by the formula.
A = P(1 + r)^t

Rate of interest is 6%
Time = 15 years
Now, According to the question:
We know that :
P = 5500
r = 6%
n = 1
t = 15
Compound Interest is given by the formula.
A = P(1 + r)^t
Substitute the values in above formula.
A = 5500. [tex](1+\frac{6}{100}/1 )^1^5[/tex]
Evaluate the equation/expression:
A = 13181.070062
Round 13181.070062 to the required place

What is fraction?A fraction is a portion of a whole or, more broadly, any number of equal pieces. In ordinary English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. A fraction is a portion of a larger total. The number is stated in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complicated fraction contains a fraction in either the numerator or the denominator.
Here,
30% of 80%
=30*100(80*100)*100
=30*80/100

Area of circle of diameter with 13cm is 132.74
What is area of circle?
The space a circle takes up in a two-dimensional plane is known as the area of the circle.Alternately, the area of the circle is the area included inside the circumference or perimeter of the circle. A = r², where r is the circle's radius, is the formula for calculating a circle's surface area. The square unit—for instance, m², cm², in², etc.—is the unit of area. In square units, the area of a circle is equal to r² or d²/4 where (Pi) = 22/7 or 3.14. The ratio of a circle's circumference to its diameter is known as pi (). This unique mathematical constant exists.Given :
Diameter of circle, d = 13cm
Radius of a circle, r = d/2
=13/2
=6.5
Area of circle = πr²
= 3.142 * 6.5 * 6.5

Use the graphs off and g to describe the transformation from the graph off to the graph g.
f(x) = -1/2x-5
g(x) = f(x-3)
The graph of f(x) is transformed 6 units horizontally to get the graph g(x). g(x) is a transformation form of the graph of f(x).
What is the reciprocal function?
The typical instance of reciprocal functions that we might run into is y = a/x, where a is a real number. Accordingly, reciprocal functions are those that have an algebraic expression in the denominator and a constant on the numerator.
Given functions are:
f(x) = -1/(2x-5)
g(x) = f(x-3)
The points on the graph f(x) = -1/(2x-5) are:
When x = 0, f(x) = 1/5
When x = 1, f(x) = 1/3
When x = -1, f(x) = 1/7
The graph of f(x) is added.
Putting x = x-3 in f(x) = -1/(2x-5) to find the function g(x):
g(x) = -1/(2x-6-5)
g(x) = -1/(2x-11)
The points on the graph g(x) = -1/(2x-11) are:
When x = 0, g(x) = 1/11
When x = 1, g(x) = 1/9
When x = -1, g(x) = 1/13

Given that,
$1000 become in a saving account at 3% per year for 3 years when the interest is not compounded.
Simple interest is defined as the percentage of earning on the lending for a period of time
Here,
Simple interest earned = P × r × t /100
= 1000 × 3 × 3 /100 = 90
Amount = P + SI = 1000 + 90 = $90
Now, when interest is compounded annually,
Amount = 1000(1.03)³
Amount = $1092.72
