The mean of the sample is affected by the outlier. The mean is non-resistant. That means, it's affected by outliers.
More specifically, the mean will want to move towards the outlier.
Say we have some information
1\s,2 \s, \s3 \s. This has a mean of 2 in it. However, if we include a 94-point outlier in the data set, the mean will change to 25. The mean shifted toward the outlier, as you can see.
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

The number of tickets that were sold for the first game was 84 tickets .
In the question ,
it is given that
the ratio of sold tickets to unsold tickets in the first game = 7:3 ,
so , number of tickets sold in first game = 7x
number of tickets unsold in the first game = 3x
the ratio of sold tickets to unsold tickets in the second game = 13:2 ,
so , number of tickets sold in second game = 13x
number of tickets unsold in the second game = 2x
given the number of unsold tickets in the second game = 24
that is 2x = 24
x = 12
number of tickets sold in first game = 7x = 7(12) = 84
Therefore , The number of tickets that were sold for the first game was 84 tickets .

What is venn diagram ?A Venn diagram is a diagram that uses circles to show the relationships between things or finite groups of things. Intersecting circles have one thing in common, but non-intersecting circles do not have these features.
Venn diagrams help visualize the similarities and differences between two concepts. They have long been recognized for their usefulness as educational tools. Venn diagrams have been used as part of introductory logic curricula and in elementary school planning around the world since the mid-20th century.
Venn diagrams help show how different concepts and elements intersect. At a glance, you can see how things are similar, how they differ, and where and how they overlap. The center of a Venn diagram (the intersection of two or more circles) often represents a connection or main idea that can be decomposed into various other circles, and labels on the outer part are more common than labels in the center. is clear. .

Two cards are drawn from a well-shuffled deck of 52 cards without replacement. Determine the probability The first card is a face card and the second card is a diamond.
The probability that the first card is a face card and the second card is a diamond is 1/17.
What is probability?Probability simply means the likelihood that a particular event will occur or take place.
Number of face cards = 12
Number of diamonds = 13
Total number of cards in a deck = 52
The probability of getting a face card is 12/52 = 3/13
The probability of getting the diamond will be 13/51
Therefore, the probability of the face card and diamond will be:
= P(face card) × P(diamond)
= 3/13 × 13/51
= 1/17.

For integral 2 15 e1/x dx. 1, the approximate value of T10 = 27.05 and M10 = 30.29
In this question, we need to find the approximations T10 and M10 for 2 15 e1/x dx. 1
i.e., To find: Integral approximate using Trapezoid rule and midpoint rule
f(x) = 15e^(1/x)
a = 1, b = 2, bx = 1/10
T10 = bx/2 [f(1) + 2f(1.1) + 2f(1.2) + 2f(1.3) + . . . + f(2) ]
= 1/20[15e + 30e^(1/1.1) + 30e^(1/1.2) + . . . + 15e^(1/2)]
= 1/20 * 30 [(e/2) + e^(1/1.1) + e^(1/1.2) + . . . + (e^(1/2) / 2)]
= 1.5 * 18.0362
= 27.05
Now we find M10
M10 = Δx [f(1.05) + f(1.15) + . . . + f(1.95)]
= 1/10 [15e^(1/1.05) + 15e^(1/1.15) + . . . + 15e^(1/1.95)]

Why is triangle area divided by 2?.
To find the area of a triangle, multiply the base area by the height and then divide by 2. Dividing by 2 comes from being able to divide a parallelogram into two triangles. For example, in the illustration on the left, the area of each triangle is equal to half the area of the parallelogram.
What is area of triangle?The area of a triangle is defined as the total space occupied by the three sides of the triangle in a two-dimensional plane.The basic formula for the area of a triangle is half the product of the base and the height, or A = 1/2 × w × h.This formula applies to all types of triangles, including scalene, isosceles, and equilateral triangles. Recall that the base and height of a triangle are perpendicular to each other.The area of a triangle is the area enclosed by the sides of the triangle.The area of a triangle varies from triangle to triangle depending on the length of the sides and the interior angles. The area of a triangle is expressed in square units. B. m2, cm2, in2, etc.Hence, To find the area of a triangle, multiply the base area by the height and then divide by 2.

The correct alternative, based on the parallel, triangle sum, and isosceles triangle criteria, is 2.
How to spot the correct optionAlternative 1
Since the base angle of an isosceles triangle is 52 degrees, let's say the third angle is x, and according to the triangle sum property,
x + 2 * 52 = 180,
x = 76.
triangle at the base
32 + 2x = 180 (triangle sum property for isosceles triangle)
x = 74
In accordance with the triangle sum property for isosceles triangles, the figure demonstrates that the base angle of the triangle at its base is also equal to 76.
False choice: Angles 74 and 76 are not equal.
Alternative 2:
x + 2 * 76 = 180 (triangle sum property for isosceles triangle)
x = 28
The diagram demonstrates that the triangle at the base angle has angle = 28.
124 + 2x = 180 (triangle sum property for isosceles triangle)
x = 28
Since the two angles 28 and 28 are equivalent, the choice is correct.

Answer:
Step-by-step explanation:
a man is in a boat that is floating 175 feet from the base of a 200 foot cliff. what is the angle of depression between the cliff and the boat?
A boat is moving 175 feet from the base and a man is in the boat. The height of cliff is 200 feet. We need to find the angle between the cliff and the boat.
We have a right angled triangle where base is 175 ft and height is 200 ft.
We know that tan θ = opposite / adjacent
= 200 / 175
So θ = tan ^-1 (200 / 175)
So θ = 48.8 degree

Options: A= 6 < x < 8; the slop is the steepest for this interval
B= 8 < x < 10; the slop is the steepest for this interval
C= 6 < x < 10; the slop is decreasing for this interval
D= 6 < x < 12; is where the slope is decreasing
Step-by-step explanation:
it decreases the fastest, where it drops the most feet in the same period of time.
the dots are made in 2 seconds intervals.
between the seconds 6 and 8 the ball drops from 65 ft to 25 ft (a drop of 65 - 25 = 40 ft).
bergen the seconds 8 and 10 the ball drops from 25 ft to 5 ft (a drop of 25 - 5 = 20 ft).
and then between the seconds 10 and 12 the ball drops from 5 ft to 0 ft (a drop of 5 ft).
so, A is the right answer. with 40 ft in 2 seconds the ball is dropping the most (= the fastest) between the seconds 6 and 8. which means the slope is negatively the steepest there = the height is decreasing the fastest.
