The sample space seems to be a collection of probable outcomes from a random variable, and the further discussion can be defined as follows:
Sample space:The sample space is a set of probable outcomes from a random experiment. Its denoted by the letter "S" the term "event" refers to that portion of the experiment's probable results depending on the experiment, a sample space may include a variety of outcomes.
Using the values that adds its value:
[tex]\to x=3+2+4[/tex]
So, the sum or difference value is 9.

Answer:
[tex] y = 4 [/tex]
Step-by-step explanation:
Given:
[tex] y = \frac{7x + 1}{3x - 6} [/tex],
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into [tex] y = \frac{7x + 1}{3x - 6} [/tex]
[tex] y = \frac{7(5) + 1}{3(5) - 6} [/tex]
[tex] y = \frac{35 + 1}{15 - 6} [/tex]
[tex] y = \frac{36}{9} [/tex]

Find an explicit formula for the geometric sequence -1,-7,-49,-343,.... Note : the first term should be d(1) . d(n) =
Answers
Answer:
dn = -7^n-1Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1

There are three nickels, four dimes, and five quarters in your pocket. You randomly pick
a coin. It is a nickel or a dime.
Answers
Answer:
0.583
Step-by-step explanation:
You have a total of 12 coins in your pockets (3 nickels + 4 dimes + 5 quarters).
There are 7 nickels/dimes (3 + 4), meaning you have a 7/12 chance of picking either a nickel or a dime.
7/12 simplifies to 0.583.
You have a 0.583% chance of picking either a nickel or a dime.
Tyler orders a meal that costs $15. The sales tax rate in Tyler's county is 6.6%. Write an equation to represent the relationship between the original cost of the meal and the cost after the sales tax. Use x for the original cost for the meal and y for the cost after sales tax.
Answers
Answer:
Step-by-step explanation:
y = (1.066)x
The equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x
How to calculate the sales tax?The sales tax is the amount charged on the price of goods and services.
Let x be the original cost for the meal
Let y be the cost after the sales
If the sales tax rate in Tyler's county is 6.6%, the tax charged is expressed as:
0.066 of theoriginal cost
0.066x
Cost after tax = original cost + tax
Cost after tax = x + 0.066x
y = 1.066x
Hence the equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x

Is negative 6 a rational number
Answers
Yes, negative 6 a rational number because it can be represented as a fraction of two integers.
A rational number is a number that can be expressed as a fraction of two integers, where the denominator is not zero.
It is any number that can be written in the form "a/b," where "a" and "b" are integers and "b" is not equal to zero.
The number -6 can be expressed as -6/1.
Here, -6 is the numerator and 1 is the denominator.
Both the numerator and denominator are integers, and the denominator is not zero.
Therefore, -6 can be represented as a fraction of two integers and meets the definition of a rational number.

The volume of a cylinder is 225π cm³ and its height is 9 cm.
What is the length of the cylinder's radius?
Enter your answer in the box.
cm
Answers
Answer:
5cm
Step-by-step explanation:
Given data
volume = 225π cm³
Height= 9cm
r= ???
Volume of cylinder
v=πr^2h
substitute
225π= π*r^2*9
225= r^2*9
r^2= 225/9
r^2= 25
r= √25
r= 5cm
Hence the radius is 5cm
Need to do this Help please

Answer:
Step-by-step explanation:
Now e have two figures
1 is ABCD and other is APQD ,
Now to find g and f,
Now the are both figure is ,
Area = length * width
Area ABCD = 39 cm^2
AB* BC = 39
(g+7) * ( f) = 39Again,
Area APQD = AP*QD= 16 cm ^2
(g)*(f)=16from here f =16/g putt it in above equation we get ,
(g+7)*16/g = 39
16*g-39*g+96 =0
-23g +96 = 0
g = 96/23
g =3 cm
Now for f putt in one of the above equation ,
f =16/3
f =5.33 cm
Answer:
f = 3cm g = 6cm
Step-by-step explanation: to find f
Subtract the area of APQD from ABCD then divide by 7
f = (39 - 18)/7
f = 21/7
f = 3
To find g, divide the area of APQD by 3
18/3 = 6
We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ

Required
Determine the equation
First, calculate the slope using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4 - (-4)}{5 -0}[/tex]
[tex]m = \frac{-4 +4}{5}[/tex]
[tex]m = \frac{0}{5}[/tex]
[tex]m = 0[/tex]
The equation is then calculated using:
[tex]y = m(x -x_1) + y_2[/tex]

A software designer is mapping the streets for a new racing game. All of the streets are depicted as either perpendicular or parallel lines. The equation of the lane passing through A and B is -7x + 3y = -21.5. What is the equation of the central street PQ?
A. -3x + 4y = 3
B. -1.5x − 3.5y = -31.5
C. 2x + y = 20
D. -2.25x + y = -9.75
Answers
Answer:
[tex]-1.5x - 3.5y =- 31.5[/tex]
Step-by-step explanation:
Given
AB: [tex]-7x + 3y = -21.5[/tex]
[tex]PQ(x_1,y_1) = (7,6)[/tex]
Required
Determine the equation of PQ
First, we calculate the slope of AB:
[tex]-7x + 3y = -21.5[/tex]
Make 3y the subject
[tex]3y = 7x - 21.5[/tex]
Make y the subject
[tex]y = \frac{7}{3}x - \frac{21.5}{3}[/tex]
An equation has the general form:
[tex]y = mx + b[/tex]
Where m = slope
So:
[tex]m = \frac{7}{3}[/tex] -- Slope of AB
From the attached diagram, we can see that PQ is perpendicular to AB.
This means that, the relationship between their slope is:
[tex]m_2 = -\frac{1}{m_1}[/tex]
Substitute 7/3 for m1
[tex]m_2 = -\frac{1}{7/3}[/tex]
[tex]m_2 = -\frac{3}{7}[/tex]
The equation of PQ is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = m_2 = -\frac{3}{7}[/tex]
and
[tex]PQ(x_1,y_1) = (7,6)[/tex]
So, we have:
[tex]y - 6 = -\frac{3}{7}(x - 7)[/tex]
Multiply both sides by 7
[tex]7(y - 6) = -\frac{3}{7}(x - 7)*7[/tex]
[tex]7y - 42 = -3(x-7)[/tex]
Open bracket
[tex]7y - 42 = -3x + 21[/tex]
Collect Like Terms
[tex]3x + 7y = 42 + 21[/tex]
[tex]3x + 7y = 63[/tex]
Divide through by -1/2
[tex]-\frac{1}{2}(3x + 7y) = -\frac{1}{2}*63[/tex]
[tex]-1.5x - 3.5y =- 31.5[/tex]
The equation of PQ is: [tex]-1.5x - 3.5y =- 31.5[/tex]

B. -1.5x − 3.5y = -31.5
