Values that are computed from a complete census, which are considered to be precise and valid measures of the population, are referred to as:
Parameters are the values that are computed from a complete census, which are considered to be precise and valid measures of the population. So, option(b) is right one.
In statistics, a population parameter is a number that identifies an entire group of people or population. This should not be confused with arguments in other forms of mathematics that refer to values that remain constant for a mathematical function. Note that the population parameter is not a statistic, it refers to data for a sample or group of the population. With good research, we can get statistics that accurately estimate the population. Statistics is a numerical measure described with sample data. Therefore, the parameter is a numerical description of the characteristic of population.

Find sin(2x), cos(2x), and tan(2x) from the given information. Sin(x) = 3/5, x in Quadrant I sin(2x) = cos(2x) = tan(2x) =
To find sin(2x), cos(2x), and tan(2x), we can use the double angle formulas:
sin(2x) = 2sin(x)cos(x)
cos(2x) = cos^2(x) - sin^2(x)
tan(2x) = 2tan(x) / (1 - tan^2(x))
We know that sin(x) = 3/5 and x is in Quadrant I, which means that cos(x) = sqrt(1 - sin^2(x)) = sqrt(1 - 9/25) = 4/5.
Now we can plug in sin(x) and cos(x) into the double angle formulas to find sin(2x), cos(2x), and tan(2x):
sin(2x) = 2sin(x)cos(x) = 2(3/5)(4/5) = 24/25
cos(2x) = cos^2(x) - sin^2(x) = (4/5)^2 - (3/5)^2 = 16/25 - 9/25 = 7/25
tan(2x) = 2tan(x) / (1 - tan^2(x)) = 2(3/4) / (1 - (3/4)^2) = 6/7
Therefore, sin(2x) = 24/25, cos(2x) = 7/25, and tan(2x) = 6/7.
Based on the given information, Sin(x) = 3/5 and x is in Quadrant I. We can find sin(2x), cos(2x), and tan(2x) using the double-angle trigonometric identities:
1. sin(2x) = 2sin(x)cos(x)
To find cos(x), we use the Pythagorean identity: sin²(x) + cos²(x) = 1
(3/5)² + cos²(x) = 1
cos²(x) = 1 - 9/25 = 16/25
cos(x) = √(16/25) = 4/5 (since x is in Quadrant I)
Now, sin(2x) = 2(3/5)(4/5) = 24/25
2. cos(2x) = cos²(x) - sin²(x)
cos(2x) = (4/5)² - (3/5)² = 16/25 - 9/25 = 7/25
3. tan(2x) = sin(2x) / cos(2x)
tan(2x) = (24/25) / (7/25) = 24/7
So, sin(2x) = 24/25, cos(2x) = 7/25, and tan(2x) = 24/7.

Suppose an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t)=-16t^2+48t+120. Find the average velocity from t=2 to t=4.
Type your answer as a number with no units.
The average velocity from t = 2s to t = 4s would be - 48 ft/s.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.
Average velocity
Average rate of change of velocity with time is called average velocity. Mathematically -
v{avg.} = Δx/Δt .... Eq { 1 }
Δx = x(4) - x(2)
Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}
Δx = - 96
Δt = 4 - 2 = 2
So -
v{avg.} = Δx/Δt = -96/2 = - 48 ft/s
Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

do single-parent families tend to be more impoverished than families with two parents? in order to test if there is a relationship between family structure and family income level, family researcher studied a sample of 35 one-parent and 65 two-parent families in a particular city to determine whether their total family income fell below the poverty level.
Yes, single-parent families tend to be more impoverished than families with two parents. the findings suggest that family structure is an important factor in understanding the prevalence of poverty in a given population.
The study of the sample of 35 one-parent and 65 two-parent families found that a significantly higher percentage of single-parent families fell below the poverty level compared to two-parent families. This result is consistent with previous research that has shown that single-parent families, particularly those headed by women, are at a greater risk of poverty due to the challenges of raising children alone and the lack of dual incomes. Additionally, single-parent families often face more barriers to obtaining education and employment opportunities that could increase their income. Overall, the findings suggest that family structure is an important factor in understanding the prevalence of poverty in a given population.

Suppose that QRS is isosceles with base q r. Suppose also that m q equals (5x - 14(degrees and Mr equals (4x - 2)degree
PLEASE HELP ME
Answer:
<S= 88degrees
<Q = <R = 46degrees
Step-by-step explanation:
Since the base angles of the isosceles triangle are equal hence;
<Q = <R
5x - 14 = 4x -2
5x - 4x = -2 +1 4
x = -2 + 14
x = 12
Since <Q = 5x - 14
<Q = 5(12) - 14
<Q = 60 - 14
<Q = 46degrees
Also <Q = <R = 46degrees
Similarly; <S + <Q + <R =180
<S +46 + 46 = 180
<+92 = 180
<S = 180 - 92
<S= 88degrees

What are the roots of the quadratic equation x² 5x â 6?
The roots of the equation x^2 + 5x - 6 are 1.5 and -3.5.
The roots of the quadratic equation x^2 + 5x - 6 are the values of x that make the equation equal to zero.
To find the roots of this equation, you can use the quadratic formula, which is a formula that allows you to solve any quadratic equation of the form ax^2 + bx + c = 0. The quadratic formula is: x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
In this case, the coefficients a, b, and c are 1, 5, and -6, respectively, so the roots of the equation can be found by substituting these values into the quadratic formula: x = (-5 +/- sqrt(5^2 - 4 * 1 * (-6))) / (2 * 1)
This simplifies to: x = (-5 +/- sqrt(25 + 24)) / 2
Which further simplifies to: x = (-5 +/- sqrt(49)) / 2
So the roots of the equation x^2 + 5x - 6 are: x = (-5 + sqrt(49)) / 2 = (sqrt(49) - 5) / 2 = 1.5
x = (-5 - sqrt(49)) / 2 = (-sqrt(49) - 5) / 2 = -3.5
Therefore, the roots of the equation x^2 + 5x - 6 are 1.5 and -3.5.

The value of the derivatives of f df(x, y, z)/dx + df(x, y, z)/dy is 20, when x = 1, y = 1, and z = 1.
To determine df/dt using the chain rule, we need to compute the partial derivatives of f with respect to x, y, and z, as the derivatives of x(t), y(t), and z(t) with respect to t.
We are given that the function as f (x, y, z)= 3x² + xyz + 4y³ z²
To Find df(x, y, z)/dx + df(x, y, z)/dy when x = 1, y = 1, and z = 1.
f (x, y, z)= 3x² + xyz + 4y³ z²
Therefore,
df(x, y, z)/dx = 6x + yz
df(x, y, z)/dy = xz + 12y² z²
Now we have;
df(x, y, z)/dx + df(x, y, z)/dy
6x + yz + xz + 12y² z²

Al released his balloon from the 10-yard line, and it landed at the 16-yard line. If the ball reached a height of 27 yards, what equation represents the path of his toss?
The equation of the path of the parabola is y = a(x - 13)² + 27
Given data ,
To represent the path of Al's toss, we can assume that the path is a parabolic trajectory.
The equation of a parabola in vertex form is given by:
y = a(x - h)² + k
where (h, k) represents the vertex of the parabola
Now , the balloon was released from the 10-yard line and landed at the 16-yard line, we can determine the x-values for the vertex of the parabola.
The x-coordinate of the vertex is the average of the two x-values (10 and 16) where the balloon was released and landed:
h = (10 + 16) / 2 = 13
Since the height of the balloon reached 27 yards, we have the vertex point (13, 27)
Now, let's substitute the vertex coordinates (h, k) into the general equation:
y = a(x - 13)² + k
Substituting the vertex coordinates (13, 27)
y = a(x - 13)² + 27
To determine the value of 'a', we need another point on the parabolic path. Let's assume that the highest point reached by the balloon is the vertex (13, 27).
This means that the highest point (13, 27) lies on the parabola
Substituting the vertex coordinates (13, 27) into the equation
27 = a(13 - 13)² + 27
27 = a(0) + 27
27 = 27
Hence , the equation representing the path of Al's toss is y = a(x - 13)² + 27, where 'a' can be any real number

Rationalize the Denominator:b = 1/2 + √5 * 2 - √5/2 - √5

Simplify:b = 2 - √5
Square: A and B:a^2 = (2 + √5)^2 = 4 + 4√5 + 5
b^2 = (2 - √5)^2 = 4 - 4√5 + 5
ADD: a^2 and b^2:a^2 + b^2 = 4 + 4√5 + 5 + 4 - 4√5 + 5

So, Now we solve the Inverse property of addition: ±4 + 5 + 4 + 5
9 + 4 + 5
13 + 5 = 18
Move the expression to the right:a^2 + b^2 = 18
a^2 = 18 - b^2
Now we take the root of both sides/Negative/Positive:a = ± √18 - b^2
a = √18 - b^2
a = -√18 - b^2
Draw a conclusion:Hence, The Value of: a^2 + b^2 is 18
