The individuals of a set are the various data or variable of a data set.
The study's participants or study subjects are referred to as individuals. The trait of the person being measured or observed is known as a variable. For instance, if we were to do a research on climbers of Mount Everest, the participants would be the real climbers who succeeded in reaching the summit.
A categorical variable places each individual in to a category such as male or female.
A quantitative variable has numerical values that measure some characteristic of each individual, such as height in centimeter or salary in dollars.
The problem deals with the concept of types of variables. We use the definition of variables to identify/determine the type variable from the known information.
The individuals in the data set are vehicles or cars.
The given information is related to the different types of cars and its model, and specifications. Hence, the vehicles or cars are individuals in the data set.

Use the info
seconds
In 25.76 seconds we will fill the total volume of the cylinder.
how long will it take the faucet to fill the vase?The total volume of the cylinder is given by the equation:
V = pi*R^2*H
Where pi = 3.14, R is the radius and H is the height.
Here we know that the diameter is 6 inches, then the radius is:
R= 6in/2 = 3in
And the height is 8 inches, then the volume is:
V = 3.14*(3in)^2*8in = 226.08 in^3
We already have 20 cubic inches of water there, so what we need to fill is:
226.08 in^3 - 20in^3 = 206.08in^3
If we fill it at a rate of 8in^3/s, the time in which we will completely fill the cylinder is:
T = 206.08in^3/8in^3/s = 25.76s
In 25.76 seconds we will fill the total volume of the cylinder.

What is the difference quotient of the function, g (x) = startroot x endroot, x greater-than-or-equal-to 0?
The difference quotient of the function g(x) = √x is [√(x+h) -√x]/h
Difference quotient of the function:
Difference quotient of the function means a measure of the average rate of change of the function over an interval.
The difference quotient formula of a function y = f(x) is,
[ f(x + h) - f(x) ] / h
where
f (x + h) is obtained by replacing x by x + h in f(x)
f(x) is the actual function
Given,
Function g(x) = √x where x≥0.
Here we need to find the difference of the quotient of the function.
For that,
First we have to calculate the value of g(x + h),
By simply replacing the value of x as x + h,
So,
g(x + h) = √(x+h)
Now apply the values on the formula in order to solve it,
=> [√(x+h) -√x]/h
We can't simplify it further.
So, the difference quotient of function is,

If the length of the shorter arc AB is 22cm and C is the center of the circle then the circumference of the circle
The circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.
We are given that:
Length of the shorter arc forming an angle of 45° with the center = 22 cm
AB = 22 cm
C is the center of the circle.
We know that the length of the arc is calculated as:
Length of an Arc = θ × (π / 180) × r
22 = 45 × (3.14 / 180) × r
22 = 0.785 r
r = 22 / 0.785
r = 28.0255
Circumference = 2 π r
Circumference = 2(3.14) (28.0255)
C = 176 cm
Therefore, we get that, the circumference of the circle with arc AB as 22 cm and C as the center will be 176 cm.

Find the indicated measure
I will give brainliest to the right answer with solution
Answer:
∠ N = 10° , arc RS = 134°
Step-by-step explanation:
the measure of an inscribed angle is half the measure of its intercepted arc.
(5)
∠ N is an inscribed angle and we require arc LM
the measure of the arcs in a circle = 360°
note LN is the diameter so arc LN = 180°
Then
LM + MN + LN = 360°
LM + 160° + 180° = 360°
LM + 340° = 360° ( subtract 340° from both sides )
LM = 20°
then
∠ N = [tex]\frac{1}{2}[/tex] LM = [tex]\frac{1}{2}[/tex] × 20° = 10°
(6)
∠ Q is an inscribed angle so its intercepted arc is twice its measure
arc RS = 2 × 67° = 134°
Use the equation y-6= to fill in the missing values in the table below
Using the given equation, the missing values in the table are:
x y
32 14
12 9
0 6
-8 4
-36 -3
How to Apply an Equation?Given the equation, y - 6 = x/4, we can rewrite the equation as:
y = x/4 + 6
For x = 12, we have:
y = 12/4 + 6 = 3 + 6
y = 9
For x = 0, we have:
y = 0/4 + 6 = 0 + 6
y = 6
For y = 4, we have:
4 = x/4 + 6
4 - 6 = x/4
-2 = x/4
-8 = x
x = -8
For y = -3, we have:
-3 = x/4 + 6
-3 - 6 = x/4
-9 = x/4
-36 = x
x = -36

DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.
∠TAC = ∠ABC (The angle between the chord and the tangent is equal to the angle in the alternate segment)
Since, EDCB is a cyclic quadrilateral,
∠CBD + ∠CED = 180 ----- I
- ∠CED + ∠AED = 180 -----II
----------------------------------------------------
∠ CBD = ∠AED
Also, ∠ CBD = ∠ EAT( A is tangent to the circle)
So, ∠ EAT = ∠ AED ( Alternate interior angle)

a bottle weighs 300gand holds 630ml,how much does it weight if i fill it with water
If a bottle weighs 300g and can hold 630ml, then it will weigh approximately 930g when filled with water.
As per the question statement, a bottle weighs 300g and can hold 630ml.
We are required to find out the weight of the bottle when it is filled up with water.
To solve this question, we need to know about the concept of density of a substance, i.e.,
[tex]Density=\frac{Mass}{Volume}\\ or, Mass=[Density*Volume][/tex].
And density of water is 1gm/ml, i.e., 1gm of water has a mass of 1ml.
Using the above info, we will calculate the mass of 630ml of water and then we will have to add up the mass of water and the mas of the bottle to obtain our desired answer.
Using the unitary method, if 1ml of water has a mass of 1gm, then,
630 ml of water has a mass of [tex](630*1)=630\\[/tex] gms.
Hence, total weight of the bottle filled with water will be

Step-by-step explanation:
x^2+11x+15=30
find x
After simplifying the equation we acquire the value of x as:
x = 1.225 or x = ₋12.225
Given the equation is x² ₊ 11x ₊ 15 = 30
arrange the constants on one side.
x² ₊ 11x = 30 ₋ 15
x² ₊ 11x = 15
x² ₊ 11x ₋ 15 = 0
now simplify the equation using the formula: -b±√b²₋4ac / 2a
in the equation we have the values for a = 1 , b = 11 and c = ₋15
substitute the values and get the value of x.
= ₋11 ± √(11)² ₋ 4(1)(₋15) / 2(1)
= ₋11 ± √121 ₊ 60 / 2
= ₋11 ± √181 / 2
= ₋11 ± 13.45 / 2
= ₋11 ₊ 13.45 / 2 or ₋11 ₋ 13.45 / 2
= 2.45/2 or ₋24.45/2
= 1.225 or ₋12.225
