The characteristics of a normal distribution are  Symmetric, Unimodal,  Bell-Shaped,  Mean and Median are equal.

A. Symmetric: True. A normal distribution is symmetric, meaning the left and right halves of the distribution are mirror images of each other.

B. Unimodal: True. A normal distribution is unimodal, meaning it has a single peak.

C. Bimodal: False. A normal distribution is not bimodal; it has only one mode (peak).

D. Bell-Shaped: True. A normal distribution is bell-shaped, meaning it forms a symmetric, bell-like curve.

E. Mean and Median are equal: True. In a normal distribution, the mean and median are equal, and they both coincide with the highest point of the curve.

F. The Peak is on the left: False. The peak of a normal distribution is at the center; it is not necessarily on the left.

G. 64% of the data falls within 1 standard deviation of the mean: False. In a normal distribution, approximately 68% of the data falls within 1 standard deviation of the mean, not 64%.

Step-by-step explanation:

The square root of 8 can actually be written \(2\sqrt2\), so \(4\sqrt2 = 4 \cdot 2\sqrt2 = 8\sqrt2\)

Now, we are looking for \(\frac{8\sqrt2}{3\sqrt2}\). Both the square root of 2s cancel, so we are left with 8/3

The average daily float for the BBC Corporation, based on receiving 30 checks totaling $250,000 with an average delay of five days, is $41,667.

To calculate the average daily float, we need to determine the total amount of funds in transit and divide it by the average number of days the funds are delayed.

In this case, the BBC Corporation receives 30 checks totaling $250,000 in a typical month. The average delay for these checks is five days.

To calculate the total amount of funds in transit, we multiply the average daily amount by the average delay:

Total funds in transit = Average daily amount × Average delay

= ($250,000 / 30 days) × 5 days

= $8,333.33 × 5

= $41,666.67

Rounding to the nearest whole number, the average daily float is $41,667.

The wall will be constructed by the mason and his assistant in a total of 4.44 days, or 4 days and 10.5 hours.

To solve the problem, we can use the concept of "work done" as a unit of measurement. If we consider building the wall as a unit of work, then we can say that the mason can complete 1/8 of the work in one day, and the assistant can complete 1/10 of the work in one day. Working together, the mason and his assistant can complete 1/8 + 1/10 of the work in one day. To add these two fractions, we need to find a common denominator:

1/8 + 1/10

= 5/40 + 4/40

= 9/40

So together, the mason and his assistant can complete 9/40 of the work in one day.

To find out how long it will take them to complete the whole wall, we can set up a proportion. Let x be the number of days it will take them to build the wall together:

(9/40) × x = 1

Solving for x, we get:

x = 40/9

Therefore, it will take the mason and his assistant approximately 4.44 days, or about 4 days and 10.5 hours, to build the wall together.

MN and QR are parallel lines in the illusion at the right. the lines AB, CD, and OP contribute to the overall illusion by providing depth and perspective cues.

In the given illusion, it is evident that MN and QR are parallel to each other. This relationship can be observed by examining the arrangement of squares and straight lines. By following the lines and comparing the positions of MN and QR, it becomes clear that they never intersect and remain equidistant throughout the illusion. Hence, we can conclude that MN and QR are indeed parallel lines.

Regarding the other elements, **AB, CD, and OP are diagonal lines** in the illusion. These diagonal lines intersect the parallel lines MN and QR at various points. Each diagonal line intersects the parallel lines at a different angle, creating an optical illusion of depth and perspective. The arrangement of squares and lines in the illusion creates a visual perception that the diagonal lines are either extending towards or receding away from the viewer, enhancing the three-dimensional effect.

The matrix A' for the linear transformation T relative to the basis B' is:

A' = \(\left[\begin{array}{ccc}2&-3\\4&0\\\end{array}\right]\)

To find the matrix A' for the linear transformation T relative to the basis B', we need to determine how the transformation T maps the basis vectors of B' onto the standard basis of \(R^2\).

The basis B' = {(-2, 1), (-1, 1)} consists of two vectors.

We apply the transformation T to each basis vector and express the results as linear combinations of the standard basis vectors (1, 0) and (0, 1).

Applying T to the first basis vector, we have:

T(-2, 1) = 2*(-2) - 3*(1), 4*(-2) = (-4, -2)

Similarly, applying T to the second basis vector, we have:

T(-1, 1) = 2*(-1) - 3*(1), 4*(-1) = (-5, -4)

Now, we express these transformed vectors in terms of the standard basis:

(-4, -2) = -4*(1, 0) - 2*(0, 1)

(-5, -4) = -5*(1, 0) - 4*(0, 1)

The coefficients of the standard basis vectors in these expressions form the columns of the matrix A':

A' = \(\left[\begin{array}{ccc}-4&-5\\-2&-4\\\end{array}\right]\)

Therefore, the matrix A' for the linear transformation T relative to the basis B' is:

A' = \(\left[\begin{array}{ccc}2&-3\\4&0\\\end{array}\right]\)

The process of measuring, analyzing, enhancing, and then controlling processes once they have been brought within the narrow Six Sigma quality tolerances or standards is referred to as the

Six Sigma process

The phrase "Six Sigma" refers to a collection of quality-control methods that organisations can utilise to get rid of flaws and enhance operations so as to increase productivity and revenues. A scientist created it in the 1980s while he was employed by Motorola.

A statistical and data-driven technique called Six Sigma examines small errors or flaws. It places a focus on cycle-time gains while lowering manufacturing faults to no more than 3.4 incidents per million units or events. The fact that only 3.4 out of a million events along a bell curve will deviate by more than six standard deviations indicates that an error usually occurs with an event that deviates by six standard deviations from the mean.

Therefore, the expected annual profit of Ruby Company is 2.703 billion dollars using probability.

Let X be the annual profit of the company. We know that X follows a normal distribution with variance equal to the cube of its mean, i.e., Var(X) = (E[X])^3.

To find the expected annual profit, we need to find the mean of X, denoted as E[X].

We are given that the probability of an annual loss is 5%. This means that the probability of making a profit is 1 - 0.05 = 0.95.

Let Z be a standard normal random variable, then we have:

P(X < 0) = P((X - E[X]) / sqrt(Var(X)) < (0 - E[X]) / sqrt(Var(X)))

= P(Z < -E[X] / (E[X])^(3/2))

Since P(X < 0) = 0.05, we have:

0.05 = P(Z < -E[X] / (E[X])^(3/2))

Using a standard normal table or calculator, we can find that P(Z < -1.645) = 0.05, where -1.645 is the 5th percentile of the standard normal distribution.

Thus, we have:

-E[X] / (E[X])^(3/2) = -1.645

this equation, we get:

E[X]^(1/2) = 1.645

Taking the square of both sides, we get:

E[X] = 2.703

P(A₁ U A₃)

= P(A₁) + P(A₃) - P(A₁ ∩ A₃)

Since A₁ and A₃ are clearly mutually exclusive events, P(A₁ ∩ A₃) will be 0.

Answer: A. Mean = 9.56, Median = 11, Mode = 7

Step-by-step explanation:

The mean, median and the mode for the given data is 9.56, 9, and 7 respectively.

Given data below:

In order to find the mean, it can be calculated by dividing a sum of all the data points with the number of data points in the data set.

The formula is:

\(\bar{M}=\dfrac{\sum M}{N}\)

\(\bar{M}=\dfrac{4+6+7+7+9+11+13+14+15}{9}\)

\(\bar{M}=\dfrac{86}{9}\)

\(\bar{M}=9.56\)

Next, we will find the median.

In order to find the median, we got to place the numbers in value order and find the middle.

So,

\(\text{Median}=9\)

Lastly, we will find the mode.

To find the mode, order the numbers lowest to highest and see which number appears the most often.

So,

\(\text{Mode}=7\)

Each team member should run 9073.6 miles in the race on Course B.

Let's break down the problem step by step:

1. First, we need to find the length of Course B. We know that Course B is 212 times as long as Course A, and Course A is 214 miles. So, to find the length of Course B, we multiply:
  Course B length = 212 × 214 miles

2. Calculate the length of Course B:
  Course B length = 45368 miles

3. Now, we need to determine the distance each team member should run. There are 5 members on the team, and they need to run an equal distance on Course B. To find the distance for each member, we divide the total length of Course B by the number of team members:
  Distance per member = Course B length / number of members

4. Calculate the distance per team member:
  Distance per member = 45368 miles / 5

5. Finally, we find the distance each team member should run:
  Distance per member = 9073.6 miles

So, each team member should run 9073.6 miles in the race on Course B.

The monthly expenditure of September for question 9 and 10 are respectively $107.91 and $19892.25

From the question, it is rather easy to figure out. We are given expenditures from May through August, September missing but we are also provided with the average expenditure.

We know that the average expenditure is given as

sum of expenditure of all the months / number of months

So, for number 9, we have

[(112.11 + 97.13 + 106.45 + 121.85 + x) / 5] = 109.09

(437.54 + x) / 5 = 109.09....... if we cross multiply

437.54 + x = 109.09 * 5

437.54 + x = 545.45

x = 545.45 - 437.54

x = 107.91

And for number 10, we have

[(23687.12 + 19871.03 + 20056.90 + 24510.30 + y) / 5] = 21603.52

(88125.35 + y) / 5 = 21603.52......... if we cross multiply

88125.35 + y = 21603.52 * 5

88125.35 + y = 108017.6
