Step-by-step explanation:

Mile per hour multiplied by 1.609344 equals kilometer per hour

                                             or

Mile per hour divided by 0.621371 equal kilometer per hour

180 mph x 1.609344 = 289.68192 or when rounded to 289.68 km/h

Hope this helped!

mph × 1.609344 = km/h

180 × 1.609344 = 289.68192

180 mph ≈ 289.68 kmh

Miles per hour (mph, m.p.h., MPH, or mi/h) is a term that is used in both the United States and the British Empire to describe how many miles may be travelled in an hour. It is used in the US, the UK, and a few other smaller countries, the majority of which are former colonies of the US or the UK or have strong ties to both countries historically.

Let's first go over how many metres are in a mile and how many seconds are in an hour. The distance travelled in a specific amount of time is known as speed. The symbol for metres per second is m/s, and the symbol for miles per hour is mph.

To convert an expression into standard form a + bi, you separate the real and imaginary parts and combine them using the appropriate operators.

To write an expression into standard form, a + bi form, you need to separate the real and imaginary components of the expression and combine them using the appropriate notation.

In a + bi form, 'a' represents the real part of the expression, and 'b' represents the imaginary part.

Let's say we have an expression in the form x + yi, where 'x' is the real part and 'y' is the imaginary part.

To convert this expression into standard form, you need to perform the following steps:

Separate the real and imaginary parts of the expression.

Write the real part first, followed by the imaginary part with 'i'.

Combine the real and imaginary parts using the appropriate operators (+ or -).

Let's take an example to illustrate this process:

Suppose we have the expression 3 + 2i.

Here, '3' is the real part, and '2' is the imaginary part.

To convert it into standard form, we write it as 3 + 2i.

Similarly, if we have the expression -5 - 4i, where '-5' is the real part and '-4' is the imaginary part, we write it as -5 - 4i.

In both cases, the expressions are in standard form, a + bi.

Answer:

The answer are

A.

\( {f}^{ - 1} (x) = \frac{x + 3}{x - 2} \)

B.

\( {f}^{ - 1} ( - 3) = 0\)

Step-by-step explanation:

To find the infers we do that

\(f(x) = \frac{2 x + 3}{x - 1 } \\ (x - 1)f(x) = 2x + 3 \\ xf(x) - f(x) = 2x + 3 \\ xf(x) - 2x = f(x) + 3 \\ x(f(x) - 2) = f(x) + 3 \\ x = \frac{f(x) + 3}{f(x) - 2} \\ then \: \\ {f}^{ - 1} (x) = \frac{x + 3}{x - 2} \\ then \\ {f }^{ - 1} ( - 3) = \frac{ - 3 + 3}{ - 3 + 2} = 0\)

The best unit of measurement to represent the diameters of Mars and the Sun is millimeters.

1 kilometer = 1,000,000 millimeters

Therefore, the Sun's diameter in millimeters can be calculated as:

1.391 × 10⁶ km × 1,000,000 mm/km = 1.391 × 10¹² mm

Sun's diameter / Mars's diameter = (1.391 × 10¹² mm) / (6.794 × 10⁹ mm)

This simplifies to:

Sun's diameter / Mars's diameter ≈ 204,474

Therefore, the Sun's diameter is approximately 204,474 times greater than Mars's diameter.

The probability that a bridge hand includes 4 acres and exactly 3 kings is 0.028%

To find the probability of getting exactly 4 aces and 3 kings in a bridge hand, we can use the following formula:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52)

To calculate the numerator, we can first find the number of ways to choose 4 aces from the 4 available in the deck, and then the number of ways to choose 3 kings from the 4 available in the deck. The remaining 6 cards can be any of the 44 non-ace, non-king cards. Therefore:

Number of ways to get 4 aces and 3 kings = (4 choose 4) x (4 choose 3) x (44 choose 6) = 1 x 4 x 44,380,776 = 177,523,104

To calculate the denominator, we can find the total number of ways to choose any 13 cards from the 52-card deck:

Number of ways to select 13 cards from a deck of 52 = (52 choose 13) = 635,013,559,600

Therefore, the probability of getting exactly 4 aces and 3 kings in a bridge hand is:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52) = 177,523,104 / 635,013,559,600 = 0.0002799 or approximately 0.028%.

that it is important for likert-type scale response choices to be balanced at the ends of the response continuum. This means that there should be an equal number of positive and negative response options to avoid any bias or skew in the results.

An explanation for this is that if there are too many positive or negative response options, respondents may feel pressured to choose a certain option even if it doesn't accurately reflect their true opinion. This can result in inaccurate data and can skew the results of the survey or study.

balancing the response choices on a likert-type scale is crucial for obtaining accurate and unbiased data. By having an equal number of positive and negative options, respondents are more likely to provide honest and accurate responses.

The individual credited with devising levels of measurement in which different measurement outcomes can be classified is Stanley Smith Stevens.

Stanley Stevens was an American psychologist and professor known for his work in psychophysics and measurement theory. In 1946, he proposed a framework for levels of measurement, which became known as Stevens' levels of measurement or Stevens' scale.

Stevens recognized that different types of data or measurements have different properties and require different statistical operations. He categorized measurement scales into four distinct levels:

Nominal Scale: The nominal scale is the lowest level of measurement. It involves assigning categories or labels to objects or individuals without any inherent order or numerical value. Examples include gender (male/female), eye color (blue/brown/green), or favorite color (red/blue/green). Nominal data can be classified and counted, but arithmetic operations such as addition or subtraction are not meaningful.

Ordinal Scale: The ordinal scale represents data with categories that have a natural order or ranking. It allows for comparisons of the relative size or magnitude between categories, but the differences between categories may not be equal or meaningful. Examples include rankings (1st, 2nd, 3rd), Likert scales (strongly agree/agree/neutral/disagree/strongly disagree), or letter grades (A, B, C, D, F). Arithmetic operations are still not applicable to ordinal data.

Interval Scale: The interval scale has categories with meaningful order, and the differences between categories are equal and meaningful. It includes a fixed measurement unit but lacks a true zero point. Temperature in Celsius or Fahrenheit is a classic example of an interval scale. Arithmetic operations like addition and subtraction are meaningful, but multiplication and division are not.

Ratio Scale: The ratio scale is the highest level of measurement. It possesses all the properties of the interval scale, along with a true zero point that indicates the absence of the measured attribute. In addition to equal intervals, ratio scales allow for meaningful multiplication and division. Examples include height, weight, time, or counts of objects.

Stevens' levels of measurement provide a framework for understanding the properties and appropriate statistical analyses for different types of data.

By categorizing measurement scales into these levels, researchers can make informed decisions about the appropriate statistical techniques to use based on the nature of their data. Stanley Smith Stevens' contributions have had a significant impact on the field of measurement theory and statistical analysis.

The upper limit of the control chart such that it will include roughly 97 percent of the sample means when the process is in control is 1.008.

For a process with a normal distribution, the mean of the sample means is equal to the population mean and the standard deviation of the sample means is equal to the population standard deviation divided by the square root of the sample size. In this case, the mean of the output is 1.0 liter and the standard deviation is 0.01 liter, so the standard deviation of the sample means is 0.01 / √25 = 0.002.

To construct a control chart for the sample means, we need to determine the upper and lower control limits such that the process is in control when the sample means fall within these limits. Assuming the process is in control, we want to find the upper limit such that roughly 97% of the sample means fall below this limit.

Using the standard normal distribution, the Z-score corresponding to the 97th percentile is approximately 1.88.

Therefore, the upper control limit is 1.0 + 1.88(0.002) = 1.008. Any sample mean above this limit should be investigated for potential process issues.

Weight is defined as the quantity that shows the total amount of matter that can be found in an object and it's measured in grams or Kilograms.

The weight of the empty container = 5kg

The weight of the container and water= 13+25= 38kg

Therefore the weight of water = 38-5= 33kg

If 1 = 33kg

If area of a rectangle is 243.9 m2. If the length is 15 m, then  perimeter of the rectangle is 62.58 m.

The area of Rectangle is length times of width.

Given,

Area of rectangle (A) = 243.9 m²

Length (L) = 15 m

To find the  perimeter we need to know the breadth

Volume is a three-dimensional scalar quantity. The correct option is B, (4/3)π(10)³ - (4/3)π(4)³.

We have been given that a large sphere has a diameter of 20 feet. A smaller sphere with a radius of 4 feet is cut out of the center of the larger sphere. We are asked to find the volume outside smaller sphere and inside larger sphere.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume, in cubic units, of the shaded part of the sphere is the difference between the volume of the larger sphere and the smaller sphere. Therefore, the volume can be written as,

The volume of the sphere = (4/3)π(10)³ - (4/3)π(4)³

Hence, the correct option is B, (4/3)π(10)³ - (4/3)π(4)³.
