The measure of variation for a numerical data set describes how the values of a number vary with the single number. This measurement shows the difference in the properties of a certain number to the rest of the numbers in the numerical data set.
The term that describes how values of a numerical data set vary with a single number is 'variation'. It quantifies the spread of data values, helping to add context and meaning to averages in a data set.
Explanation:A measure of variation for a numerical data set describes how its values vary with a single number. Variation is a statistical concept that is used to quantify the spread or dispersion of a set of data values. A low variation indicates that the data points tend to be close to the mean (or expected value), while a high variation indicates that the data points are spread out over a wider range.
For example, if we have a data set of test scores, the variation can help us understand how close or far the scores are from the average test score. This provides more context and meaning to the overall average.

Angle K in △MKL is a right angle.
What is the value of tan M ?
15/17
8/17
8/15
15/8
Solution :
Given that, In triangle MKL, angle K is a right angle.
To find the value of tan M,
As we know by trigonometric ratio, that In a right angled triangle
[tex] tan (\theta)= \frac{opposite }{Adjacent} [/tex]
Here Opposite means opposite side of the angle and adjacent means side adjacent to the angle.
So, [tex] tan M= \frac{KL}{KM} = \frac{15}{8} [/tex]
Hence, Value of [tex] tan M = \frac{15}{8} [/tex] .

Which identity needs to be used to prove tan (pi/2-x)=cot x?
To prove the identity tan (pi/2-x) = cot x, we can use the identity tan(pi/2-x) = 1/tan x and simplify the expression.
To prove tan (pi/2-x) = cot x, we can use the identity tan(pi/2-x) = 1/tan x. First, rewrite tan(pi/2-x) as 1/tan x. Then, simplify 1/tan x to cot x using the definition of cot x = 1/tan x. Therefore, we have proven that tan (pi/2-x) = cot x.

To prove tan(π/2 - x) = cot x, we use the co-function identity for tangent and cotangent, showing the relation of these functions in complementary angles. This identity confirms that tan(π/2 - x) equals cot x.
To prove the identity tan (π/2 - x) = cot x, we can use a fundamental trigonometric identity. Here's how:
Recall the co-function identity: tan (π/2 - x) = cot x. This identity is derived from the relationship between tangent and cotangent in complementary angles.
Using the identity tan (π/2 - x) = cot x, we know that the tangent of an angle's complement is equal to the cotangent of the angle.
By definition, tan θ (tangent) is the ratio of the opposite side to the adjacent side in a right triangle. For the complementary angle, the roles of the opposite and adjacent sides switch, which aligns with the definition of cot x (cotangent), i.e., the adjacent side over the opposite side.
This proves that tan (π/2 - x) = cot x.

Both Dale and Chan went running for an hour. Dale ran 5 miles and Chan ran 2.5 miles. How did Dale’s distance compare to Chan’s? (Use division to compare.)
In the given hour, Dale ran 5 miles and Chan ran 2.5 miles.
Let Dale's running miles be represented by the variable D and let Chan's running miles be represented by the variable C.
In-order to compare Dale's running miles to Chan's by using division we get:
[tex] \frac{D}{C}=\frac{5}{2.5} = \frac{2}{1} [/tex]
[tex] D=2C [/tex]
Thus, Dale ran twice the distance Chan ran in the same amount of time of 1 hour.
Equivalently we can say that Chan ran half the distance Dale ran in the same amount of time of 1 hour.

What is Dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image. Dilation comes in two varieties:
Increase in an object's size is referred to as expansion.Contraction is the reduction of an object's size.Given:
Δ RST was dilated by a scale factor of 1/2
and, Δ R'S'T' is an isosceles triangle with measurement 8 units.
As, Pre-image = measure of pre-image x scale factor
So, the measure of pre-image = 8 ÷ 1/2
= 8 x 2/1
= 16 units.
Hence, the length of a leg of the pre-image is 16 units

Explanation:The question involves solving quadratic equations and using the discriminant to determine the number of real solutions. The quadratic formula, \(x = \frac{-b \pm \sqrt[tex]{b^2[/tex] - 4ac}}{2a}\), is a powerful tool in finding the roots of any quadratic equation of the form \([tex]ax^2[/tex]+ bx + c = 0\). The discriminant, \(\Delta =[tex]b^2[/tex] - 4ac\), helps in understanding the nature of the roots without actually solving the equation. If \(\Delta > 0\), there are two distinct real solutions; if \(\Delta = 0\), there is exactly one real solution; and if \(\Delta < 0\), there are no real solutions and instead two complex solutions.

What is the missing constant term in the perfect square that starts with x²+6x?
The expression given to us is: x²+6x
Now, we know that the second term is twice the square root of the first and the last terms. Let us call the last term as [tex] y^2 [/tex]. Thus our given expression will become:
[tex] x^2+6x+y^2 [/tex].
Now, since the middle term is 6x and since we know that the second term is twice the square root of the first and the last terms, therefore,
[tex] 6x=2\times \sqrt{x^2} \times \sqrt{y^2} [/tex]
[tex] 6x=2\times x\times y [/tex]
[tex] \therefore y=3 [/tex] (By dividing both sides by 2x)
Therefore, the missing term is 3.

Credit card B, because its effective interest rate is about 0.13% less than that of credit card A.
The deal of Credit card A is du to higher interest rate.
What is compound interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.
Given
APR of credit card A = 25.68% compounded monthly
APR of credit card B = 25.32% compounded daily
other details are same
let principle be 100
time = 1 year
Amount for Credit card A = P[tex](1 + \frac{r}{n})^{n t}[/tex]
where r = rate, t = time, n = time frequency
A = 100[tex](1 + \frac{0.2568}{12})^{12*1 }[/tex]
A = 128.92
amount for credit card B
A = 100[tex](1 + \frac{0.2532}{360})^{360*1 }[/tex]
A = 128.78

describe the graph of a quadratic function
The graph of a quadratic function, or a parabola, is U or n-shaped and its direction depends on the sign of the coefficient of the x-squared term. The vertex and line of symmetry can be found using formulas based on this coefficient.
Explanation:The graph of a quadratic function, also known as a parabola, generally takes on a 'U' or 'n' shape. The direction that the 'U' faces depends on the sign of the coefficient, which is the number associated with the x-squared term in the equation. If this coefficient is positive, the graph opens upwards; if it's negative, the graph opens downwards. The vertex (the highest or lowest point on a parabola) can be calculated using the formula -b/2a. The line of symmetry can be found using the equation x = -b/2a.
For example, consider the quadratic function f(x)=x^2. This equation represents a parabola that opens upwards. Its vertex is at the point (0,0) and its line of symmetry is x=0.
