The data distribution is skewed and the mean of the emails is less than the median number of emails.
The median is 22 and the mean is 20.2.
How to find the mean and median ?The mean can be found by adding up the number of emails and dividing it by the number of days :
= ( 15 + 16 + 18 + 19 + 22 + 22 + 22 + 22 + 23 + 23 ) / 10
= 20. 2
The median is the number in the middle. As there are 10 numbers, the median would be:
= (Position 5 + Position 6) / 2
= ( 22 + 22 ) / 2
= 22
The mean is less than the median.

bekah has exactly three brass house number digits: $2$, $3$ and $5$. how many distinct numbers can she form using one or more of the digits?
There are seven elements in the set S, which represents the total number of distinct numbers we can form using one or more of the digits.
To find out how many distinct numbers we can form using these digits, we need to consider all possible combinations of digits. We can use one, two, or all three digits to form a number.
If we use only one digit, we can form three distinct numbers: 2, 3, and 5.
If we use two digits, we can form three distinct two-digit numbers: 23, 25, and 35. We cannot form the number 32 because we do not have the digit 2 available twice.
If we use all three digits, we can form only one three-digit number: 235.
Therefore, in total, we can form 7 distinct numbers using one or more of the digits 2, 3, and 5.
Mathematically, we can represent the solution as follows:
Let S be the set of all distinct numbers we can form using one or more of the digits 2, 3, and 5.
Then, S = {2, 3, 5, 23, 25, 35, 235} = 7

Write a function in the form y=Mx+b for the line that contains the points (6.4,2.6)and(5.2,9)
First solve for the slope, m using the two points given. It doesn't matter which point you choose as point 1 or 2 as long as you're consistent.
m = (y2 - y1)/(x2 - x1)
point 1: (6.4, 2.6)
point 2: (5.2, 9)
m = (9 + 2.6)/(5.2 + 6.4)
m = (9 + 2.6)/(5.2 + 6.4)
m = 11.6/11.6
m = 1
put the newly found slope into the linear equation for m

What is the area of the shaded segement?Given that;
Area of segment = Area of sector - Area of triangle.
Area of sector = (θ/360) × πr²

Using Pythagorean theorem and similar triangle theorem, the length of x is 1.123 units
What is similar side theorem?Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other. Similar triangles look the same but the sizes can be different. In general, similar triangles are different from congruent triangles.
According to the SSS similarity theorem, two triangles will the similar to each other if the corresponding ratio of all the sides of the two triangles are equal. This criterion is commonly used when we only have the measure of the sides of the triangle and have less information about the angles of the triangle.
In this problem, we can use SAS or SSS theorem, however, we can decide to use the angle to find the length of the side;
Using SOHCAHTOA
we have hypothenuse and angle and we need to find the opposite side;
sin √8 = a / 4
a = 4sin√8
Let's find the hypothenuse side of the smaller triangle
using similarity theorem;
6√2 / 4 = b / 1
b = 6√2 / 4
But knowing that the ratio of the bigger triangle is 4 to 1 to the smaller triangle, we can easily find x
cos √8 = y / 4
y = 4cos√8
The length of the opposite side to the other triangle will be
6√2 - 4cos√8 = 4.49
Using this value, we can find the hypothenuse with Pythagorean theorem
c² = 4.49² + (4sin√8)²
c = 4.49
x = 4.49 / 4
x = 1.123

How do you find the limit of this sequence?
Please be detailed!!
Answer:
0
Step-by-step explanation:
The limit of a sequence is the value that its terms approach.
We can present the limit of the terms in the sequence as:
[tex]\lim_{n \to \infty}\dfrac{1}{n^n}[/tex]
To evaluate this limit, we can plug infinity (the value that n is approaching) into the expression:
[tex]\lim_{n \to \infty}\dfrac{1}{n^n}[/tex]
[tex]= \dfrac{1}{\infty^\infty}[/tex]
We know that infinity to any positive power is still infinity. So, this expression simplifies to:
[tex]= \dfrac{1}{\infty}[/tex]
Any real number, no matter how large, is inconsequential (infinitely small) compared to infinity. Therefore, this expression evaluates to 0:
[tex]= 0[/tex]
So, the limit of the sequence [tex]\sum_{n=1}^{\infty} \dfrac{1}{n^n}[/tex] is 0.
__
Note: You could also deduce the limit of this sequence by plugging in larger and larger numbers:
[tex]\begin{array}{c | c | c}n & \text{seq. term} & \text{decimal} \\\cline{1-3} 2 & 1/4 & 0.25 \\3 & 1/81 & 0.012\\4 & 1/256 & 0.0039 \\5 & 1/3125 & 0.00032 \\... & ... & ... \\\infty & 1/\infty & 0\end{array}[/tex]
come up with a situation that you believe could follow a binomial distribution. explain why you believe it is reasonable to expect this situation to fit a binomial distribution.
A situation that could follow a binomial distribution is the number of heads that occur when flipping a "fair-coin" multiple times.
A "Binomial-Distribution" is defined as a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial has the same probability of success.
In this case, flipping a "fair-coin" is an independent trial with two possible outcomes (heads or tails), and the probability of getting a heads on any given flip is 0.5.
Each "coin-flip" is independent of the others, and the probability of getting a heads on any given flip is always the same which is "0.5",
So, this situation fits the requirements for a binomial distribution.
The "binomial-distribution" can then be used to calculate the probability of getting a certain number of heads out of a fixed number of flips. For example, if we flip a coin 10 times, the probability of getting exactly-5 heads can be calculated using the binomial distribution formula.

4. Use the functions below to complete Parts I and II.
f(x) = x2 g(x) = (x – 3)2 + 2
Part I: The graph of f(x) is shown below. g(x) has the same shape as f(x), but is shifted as described by the equation g(x) = (x – 3)2 + 2. Draw and label the graph of g(x) on the same grid as f(x). (3 points)
HINT: Making a table of values for g(x) may help you to graph it.
Part II: Describe how the graph of g(x) relates to the graph of its parent function, f(x). (3 points)
HINT: Think about how f(x) was shifted to get g(x).
Answer:
The answer as follows
Step-by-step explanation:
Part I:
The graph of f(x) is a parabola with its vertex at the origin, opening upward.
To graph g(x), we can start by shifting f(x) 3 units to the right and 2 units up, according to the equation g(x) = (x - 3)² + 2. This means that the vertex of g(x) will be at the point (3, 2).
We can create a table of values for g(x) to plot some points and draw the graph:
| x | g(x) |
|----|------|
| 0 | 11 |
| 1 | 8 |
| 2 | 5 |
| 3 | 2 |
| 4 | 5 |
| 5 | 8 |
| 6 | 11 |
Using these points, we can draw the graph of g(x) as a parabola that has the same shape as f(x), but is shifted to the right by 3 units and up by 2 units:
Part II:
The graph of g(x) is the graph of its parent function, f(x), shifted 3 units to the right and 2 units up. This means that every point on the graph of g(x) is 3 units to the right and 2 units up from the corresponding point on the graph of f(x).
In other words, the transformation that was applied to f(x) to get g(x) is a horizontal shift to the right by 3 units and a vertical shift up by 2 units. This is reflected in the equation g(x) = (x - 3)² + 2.

5x + 9 = 9x + 2
Rearranging the equation for like terms on each side
9x - 5x = 9 - 2

This season, the probability that the Yankees will win a game is 0.53 and the probability that the Yankees will score 5 or more runs in a game is 0.51. The probability that the Yankees win and score 5 or more runs is 0.43. What is the probability that the Yankees will win when they score fewer than 5 runs? Round your answer to the nearest thousandth.
The probability that the Yankees will win when they score fewer than 5 runs is about 0.102.
Let A be the event that the Yankees win, and let B be the event that the Yankees score 5 or more runs. We know that;
P(A) = 0.53
P(B) = 0.51
P(A and B) = 0.43
We want to find the probability that the Yankees win when they score fewer than 5 runs. This can be expressed as;
P(A and not B)
We can use the formula;
P(A and B)=P(B | A) × P(A)
to find;
P(B | A) = P(A and B) / P(A)
= 0.43 / 0.53
≈ 0.811
This means that given the Yankees win a game, the probability that they score 5 or more runs is about 0.811. Therefore, the probability that they win when they score fewer than 5 runs is;
P(A and not B) = P(A) - P(A and B)
= 0.53 - (0.811 × 0.53)
≈ 0.102
