The display of data and outliers

The numbers 3 and 85, which are at the extremes and are hence outliers in the number line above, may be seen to be at these extremes.

The group's outliers are a part of it, but they are not close to the other group members.

Outliers are a concern since they cause an imbalance in the data set, which is why they are typically eliminated. Furthermore, an error can sometimes cause an outlier to appear in a data collection.

The face angle relates to human faces in relation to primate faces, which are less protruded forwards (i.e., we have relatively flat faces), and the foramen magnum is the hole in the base of the skull through which the spinal column connects to the skull. In bipeds, we would expect this hole to be fairly equally distant from the back of the skull to the front of the skull,

Last week Bob was paid total of $480 for the items that he produced that week and this week Bob produced 2 items more than last week and was paid a total of $510 for the items that he produced this week.

Let's start with the simplest case:

he produced 36 or less items this week.

In this case he produced less than 36 items last week too.

So he was paid the same amount of dollar per item. Using assumptions (1) and (2), we have:

$480 + 2X = $510

⇒2X=510-480$

⇒2X=$30

⇒2X=$30/2

⇒X=$15

He was paid $15 per item.

Last week he received his $480.

480/15= 32 items.

This week he received his $510.

510/15=34 items. Other cases have no solution.

Based on the probability values, the value of the probability notation P(B|A) is 9/11

The given parameters from the question are given as

P(A) = 2/3

P(B) = 3/5

P(AB) = 11/15

Before solving the probability notation P(B|A), we start by calculating the probability expression

This is represented as

P(B|A) = P(AB)/P(A)

Substitute the known values in the above equation, so, we have the following representation

P(B|A) = (3/5)/(11/15)

Express the quotient expression as products

So, we have the following representation

P(B|A) = 3/5 * 15/11

Divide 15 and 5 by 5

This gives

P(B|A) = 3/1 * 3/11

So, we have

P(B|A) = 3 * 3/11

Multiply 3 and 3

P(B|A) = 9/11

Hence, the value of the probability is 9/11

The bearing of A route from C is  67.2°.

What is an angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which means "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

Here, we have

B traveled on a bearing of 150 and A traveled on the north side of B.

To find angle C, we have to use the cosine rule and we get

12² = 8² + 10² - 2 × 8 × 10 × cosC

C = 82.8°

The bearing of A from C will be

The unknown value x = 2 after substitution for the value y = -5x for y = 2x - 4.

Substitution in mathematics is the process for solving systems of equations that include solving for one variable and using that solution to find the other (or unknown) variable.

For y = 2x - 14 and y = -5x, we substitute the value -5x for y in the equation y = 2x - 4 to find the unknown value x;

-5x = 2x - 14

add 5x to both sides of the equation

5x - 5x= 2x + 5x - 14

0 = 7x - 14

add 14 to both sides of the equation

14 = 7x - 14 + 14

14 = 7x

x = 14/7

Opposite angles(intersection property):

Sum of angles in a triangle = 180°

So:

y=-x+6

Step-by-step explanation:

For linear graphs, the slope of perpendicular lines must be of equal value but opposite in sign: ([tex]m_1=-m_2[/tex]).

The slope of y=x+1 is 1, therefore the slope of the perpendicular line must be -1.

Given (x,y)=(-2,8) the equation of the perpendicular line can be obtained by substituting these values into the slope-intercept form y=mx+b.

8=(-1)(-2)+b

8=2+b

6=b

So, the perpendicular line has a slope-intercept form of y=-x+6 or y=6-x.

Then, 14 pennies = 14 cents

And, a nickel worth 5 cents

And, a dime worth 10 cents

Then, 32 dimes = 32*10 = 320 cents

And, a quarter worth 25 cents

Then, 48 quarters = 48*25 = 1200 cents

And, a half dollar worth 50 cents

Then, 7 half dollars = 7*50 = 350 cents

And, a dollar worth 100 cents

Then, 9 dollars = 9*100 = 900 cents

2x+y-3 = 0 iS a linear function with coefficient as 2 and 1 with constant part c = 3.

In a graph, a linear function is one that generates a straight line. The degree of the polynomial function is often either maximum 1 or minimum 0. Despite the fact that both calculus and linear algebra can be used to express linear functions. The function notation is the only thing that differs. Also required is the ability to read an ordered pair expressed in function notation. A function is denoted by the notation f(a), where an is an independent variable on which the function depends. The straight line on the linear function graph contains the expression or formula;

Linear function can be always represented in the format of ax + by + c = 0.

Here,

a € ( -∞, +∞)

b € ( -∞, +∞)

c € ( -∞, +∞)

Hence, Linear expression always contains y¹ and x¹.

and can always be represented in the form of y = mx.

So it always represents the straight line.

For example: 2x+y-3 = 0 ia a linear expression with coefficient as 2 and 1 with constant part c = 3.
