They are particularly useful when working with data sets that contain outliers or skewness.
The median provides an indication of the central tendency of the data, representing the value that separates the data into two equal parts, with half the data being below and half the data being above that value. The IQR, on the other hand, provides information about the spread of the data and can be used to identify outliers.

two sides of a trapezium have been extended to for a triangle as shown below.
work out the sizes of angles x and y give your answer in degrees
Answer:
x = 63° , y = 83°
Step-by-step explanation:
In a trapezium
each lower base angle is supplementary to the upper base angle on the same side , then
x + 117° = 180° ( subtract 117° from both sides )
x = 63°
the sum of the 3 angles in the outer triangle = 180° , that is
x + y + 34° = 180° ( substitute x = 63° )
63° + y + 34° = 180°
97° + y = 180° ( subtract 97° from both sides )
y = 83°

Find an equation of the tangent plane to the given surface at the specified point.
z =( ex − y 5), (3, 3, 6)
Please explain steps
This is an equation is e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6
What do you mean by tangent?In mathematics, a tangent is a line that touches a curve at a single point and has the same slope as the curve at that point. The tangent can be thought of as an approximation of the curve at the point where it touches it.
The concept of the tangent is used in calculus and other branches of mathematics to study the properties of curves and to analyze their behavior. The derivative of a function at a point is defined as the slope of the tangent to the curve of the function at that point. The derivative is a fundamental concept in calculus and is used to study the rate of change of a function, the optimization of functions, and to solve problems in many different fields.
To find the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6), we need to find the normal vector of the surface at that point, and use that to find the equation of the plane.
The normal vector can be found using the gradient of the surface, which is given by the partial derivatives of the function:
∇f = ∇(e^(x - y^5)) = (e^(x - y^5), -5e^(x - y^5)y^4, 1)
Evaluating this at the point (3, 3, 6), we get:
∇f(3, 3, 6) = (e^(3 - 3^5), -5e^(3 - 3^5)3^4, 1) = (e^-138, -5e^-138 * 81, 1)
So the normal vector of the surface at the point (3, 3, 6) is (e^-138, -5e^-138 * 81, 1).
To find the equation of the tangent plane, we need to find a point on the plane, and use that along with the normal vector. We already know that the point (3, 3, 6) is on the surface, so we can use that as a point on the plane.
Using the point-normal form of a plane, the equation of the tangent plane is given by:
ax + by + cz = d
Where (a, b, c) is the normal vector and (x⁰, y⁰, z⁰) is a point on the plane.
Substituting the values, we get:
e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6
This is the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6).

The tangent line to the parabola y = x² at the point (6, 36) is (0.141, 1.68)
How to find the unit vector parallel to the tangent lineThe equation of the tangent line at the point (6, 36) can be found using the derivative of the function and the point-slope form of a line:
f(x) = x²
f'(x) = 2x
y = f'(x) * (x - 6) + 36
Substituting f'(x) = 2x,
y = 2x * (x - 6) + 36
Now, we can find a unit vector that is parallel to this line by finding a non-zero multiple of the direction vector of the line, which is (1, 2x), and normalizing it.
To normalize, we divide by the magnitude, which is sqrt(1^2 + (2x)^2) = sqrt(1 + 4x^2).
Let's use x = 6:
y = 2 * 6 * (x - 6) + 36
y = 72
So, the direction vector is (1, 12) and its magnitude is sqrt(1 + 144) = sqrt(145) = 7.07.

Step-by-step explanation:
Chris saved x dollars and spent half of his savings buying video games. After earning an additional $20 cutting grass, he had $60. If the equation one half times x plus 20 equals 60 represents the scenario, how much did he start with in his savings?.
After considering all his earnings and savings, we found that Chris started with $120 in his savings.
Let's assume that Chris saved x dollars. According to the equation, he spent half of his savings, so he spent 0.5 * x dollars on video games. After earning an additional $20 cutting grass, his total savings became 0.5 * x + 20 = 60. To solve for x, we can subtract 20 from both sides of the equation, which gives us 0.5 * x = 40.
Then, we can divide both sides of the equation by 0.5 to obtain x = 80. This means that Chris started with $80 in savings, which he then doubled by spending half of his savings and adding $20 earned from cutting grass, resulting in $120 in total savings.

What is moment of inertia?A body's moment of inertia, which is determined by multiplying each particle's mass by the square of its distance from the rotational axis, is what causes it to resist angular acceleration.A measurement of an object's resistance to changes in its rotating motion is the moment of inertia. A body's resistance to variations in rotation is measured by its cross-moment section's of inertia. Depending on how far away from the center of the body each component is. The moment of inertia is calculated as the sum of the mass of the section and the square of the distance from the centroid of the section to the reference axis.Therefore,
When the rod's axis passes through the end of the rod, the moment of inertia can also be stated using a different formula. In this instance, we apply I = 13 ML².

The scale factor of the dilation is given by the equation s = 2.5
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the triangle be represented as RST
Let the dilated triangle be represented as R'S'T'
Now , the coordinates of ΔRST is
The coordinate of R = R ( 0 , 4 )
The coordinate of S = S ( 2 , 4 )
The coordinate of T = T ( 2 , 2 )
And , the coordinates of ΔR'S'T' is
The coordinate of R' = R' ( 0 , 10 )
The coordinate of S = S ( 5 , 10 )
The coordinate of T = T ( 5 , 5 )
So , the dilation scale factor is given by coordinate of R' / coordinate of R
Substituting the values in the equation , we get
Scale factor s = 10/4
Scale factor s = 5/2
Scale factor s = 2.5
Hence , the dilation scale factor is 2.5

Let f be the continuous function defined on (−1,8) whose graph, consisting of two line segments. Let g and h be the function defined by g(x)=√x^2−x−3 and h(x)=5e^x−9sinx. The function is defined by m(x)=f(x)/2g(x). Find m′(5).
The function is defined by m(x)=f(x)/2g(x) is m′(5))=[tex]\sqrt[3]{3/2}[/tex] on graph.
How to defined the function?A function is a relation that is "well-behaved," by which we mean that, given a starting point, we know the exact one ending spot to go to; given an x-value, we get only and precisely one corresponding y-value. As a result, even though all functions are relations [since they pair information], not all relations are functions. Family members who behave well are a subset of all your relations, just as well-behaved functions are a subset of all mathematical relations.)
f(x)=2x+3,XE[-1,2]
-2/3x+25/3, XE[2,8]
g(x)=√x^2−x+3 XE
m′(5))=[tex]\sqrt[3]{3/2}[/tex]
The thing to notice here is that f(x) is expressed differentially in different domain.
