Answer 1

In mathematics, there are two main types of numbers namely real numbers and complex numbers. Real numbers are grouped into two main groups known as rational numbers and irrational numbers.

-⅝ is a rational number and a real number; Options B & D are correct.

A) -⅝ is not a whole number because it is a fraction as it has both denominator and numerator.

B) -⅝ is a rational number because it is expressed as a fraction of two integers.

C) Natural numbers are simply non-zero positive integers. That is non-zero positive while numbers. Thus, -⅝ is not a natural number.

D) Real numbers are non-complex numbers. Which means rational and Irrational numbers. Thus, - ⅝ is a real number.

E) integers are any positive or negative numbers that are not fractions or decimals. - ⅝ is a fraction and so it is not an integer.

F) An Irrational number cannot be written in form of common fractions or simply put cannot be written as a fraction of 2 integers.

-⅝ is expressed in form of 2 integers. Thus, it is not Irrational.

A recent survey indicated that the mean time spent on a music streaming service is 210 minutes per week for the population of a certain country. A simulation was conducted to create a sampling distribution of the sample mean for a population with a mean of 210. The following histogram shows the results of the simulation.Which of the following would be the best reason why the simulation of the sampling distribution is not approximately normal?

Answers

The population size varies in several ways. The sample size was insufficient, which is the best explanation for why the simulation of the sampling distribution is not roughly normal.

A person's or a researcher's choice of sample size will limit the study's statistical power if it is too small or inadequate for the alpha level and the analyses they have decided to do.

Because of the aforementioned, it is much harder to determine from one's sample whether a statistical effect is existent in the population.

A sample size that is either too small or too large can affect the ability to extrapolate the results, with the latter increasing the detection of differences and accentuating statistical differences that are not clinically significant.

The complete question is:-

A. The samples were not selected at random.

B . The sample size was not sufficiently large.

C. The population distribution was approximately normal.

D. The samples were selected without replacement.

E. The sample means were less than the population mean.

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =. In its most basic form, an equation is a mathematical statement that shows that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical equation that depicts the relationship between two expressions on opposite sides of the sign. It mostly consists of one variable and one equal to symbol. 2x - 4 = 2 is an example.

hw to solve 6x-12/3+4=18/x

Answers

The two solutions of the equation:

(6x - 12)/3 + 4 = 18/x

Are x = 3 and x = -3

How to solve the equation?

Here we have the following equation:

(6x - 12)/3 + 4 = 18/x

Notice that in the right side we have x on a denominator, then x can not be zero, so x ≠ 0.

Now, let's start by simplifying the left side:

(6x - 12)/3+ 4 = 18/x

2x - 4 + 4 = 18/x

2x = 18/x

Now we can multiply both sides by x so we get:

2x^2 = 18

Now divide both sides by 2:

x^2 = 18/2

x^2 = 9

Finally, apply the square root in both sides:

√x^2 = ±√9

x = ±3

The two solutions are x = 3 and x = -3

A card is drawn at random from a standard deck of playing cards (no jokers). If it is red, the player wins 1 dollar; if it is black, the player loses 2 dollars. Find the expected value of the game. Express your answer in fraction form.

Answers

The expected value of the game is -1/2.

This means that, on average, the player can expect to lose 1/2 dollar per game in the long run.

To find the expected value of the game, we need to calculate the probability of each outcome and multiply it by its associated value, then sum up the results.

In a standard deck of playing cards, there are 26 red cards (13 hearts and 13 diamonds) and 26 black cards (13 clubs and 13 spades).

Since drawing a card is a random event, the probability of drawing a red card is the number of favorable outcomes (red cards) divided by the total number of possible outcomes (52 cards).

Probability of drawing a red card:

P(Red) = Number of red cards / Total number of cards = 26/52 = 1/2

Now, let's calculate the expected value:

Expected Value = (Probability of winning) × (Value of winning) + (Probability of losing) × (Value of losing)

In this game, if the player wins, they gain 1 dollar, and if they lose, they lose 2 dollars.

Expected Value = (1/2) × (+1) + (1/2) × (-2) = 1/2 - 2/2 = -1/2

The average time for riders to board the Twisting Thunder roller coaster is 49 seconds, with a standard deviation of 7.1 seconds.

The likelihood in a random sample of 32 is

z= (x-μ)/σ

z=(32-49)/7.1

z= -2.394

P(x32) =0.0083246 from the Z-Table

The average time to board the Spiral Wonder roller coaster is 44.8 seconds, with a standard deviation of 3.7 seconds.

In a random sample of 36, the probability is

z= (x-μ)/σ

z=(36-44.8)/3.7

z= -2.37838

P(x36) = 0.0086945 from the Z-Table

In a random sample of 32 times loading Twisting Thunder and 36 times loading Spiral Wonder, the probability is P(x32)/P(x36)=0.0083246/0.0086945 =0.9574.

Te solutions to the linear equation given as y = 12x + 24 are (0, 24), (1, 36) and (2, 48)

How to determine the solutions to the linear equation?

From the question, the linear equation is given as

y = 12x + 24

To determine the solutions, we assume values for the variable x and then calculate the y values

Having said that, we have

y = 12x + 24

Set x = 0

So, we have

y = 12 x 0 + 24 = 24

Set x = 1

So, we have

y = 12 x 1 + 24 = 36

Set x = 2

So, we have

y = 12 x 2 + 24 = 48

So, the ordered pairs of the solutions are (0, 24), (1, 36) and (2, 48)

c. the petrochemicals industry
d. texas’ location and climate

Answers

Texas' location and climate led to the development of the aviation industry.

What is the significance of Texas in the development of the aviation industry?

The development of the aviation industry in Texas can be attributed to its favorable geographical location and climate. Texas is located in the southern part of the United States, making it a strategic location for air travel between the east and west coasts of the country. Additionally, its warm and dry climate provided ideal conditions for flight testing and training.

Reason what led to the development of the aviation industry :

Texas has a long history of aviation, with the Wright brothers conducting one of their earliest flight demonstrations in the state in 1910. The establishment of military bases during World War II and the subsequent development of aircraft training facilities in Texas further fueled the growth of the aviation industry in the state. Additionally, the placement of the Johnson Space Center in Houston helped to establish Texas as a hub for aerospace research and development. However, it is Texas' favorable location and climate that truly made it a prime location for the aviation industry. Its central location made it a strategic location for air travel and logistics, while its warm and dry climate provided ideal conditions for flight testing and training. Today, Texas remains one of the top states for aviation and aerospace industries, with major airports, aircraft manufacturers, and research institutions located throughout the state.

Therefore, option (d) is correct.
