Among the measures of central tendency (mean, median, mode), the median must be an actual piece of data in the distribution.

The median is the middle value of a dataset when it is arranged in ascending or descending order. It represents the value that divides the dataset into two equal halves. Since it is based on the actual data points, the median must be one of the actual values in the distribution.

In contrast, the mean is calculated by summing all the data points and dividing by the total number of data points.

The mode represents the most frequently occurring value(s) in the dataset. These measures do not necessarily have to correspond to actual data points in the distribution.

It will take them 2 hours to do the whole task if they work together.

If one person can do a task in 3 hours and another person can do the same task in 6 hours, then we can calculate their individual rates of work as follows:

The first person can do 1/3 of the task per hour (since it takes them 3 hours to do the whole task).

The second person can do 1/6 of the task per hour (since it takes them 6 hours to do the whole task).

When they work together, their rates of work will add up, so their combined rate of work is:

1/3 + 1/6 = 1/2

This means that working together, they can do 1/2 of the task per hour. To find out how long it will take them to do the whole task, we can use the formula:

time = work ÷ rate of work

Since the whole task is 1 unit of work, and their combined rate of work is 1/2 units per hour, we can plug in these values to get:

time = 1 ÷ (1/2) = 2 hours

Step-by-step explanation:

Probability that the drug will be ineffective in more than two cases is 0,68.

Drug is effective in 9 cases out of 10, so the drug:

If the drug is tested on 12 patients, then there are 13 possibilities, namely:

In the problem, asked to find the probability of the drug being ineffective in more than 2 patients, there are 10 possibilities, namely

The way to find out the possibility of a drug being effective in 0-9 patients is:

P(effective ≤ 9) = P(effective 9) + P(effective 8) + ... + P(effective 0)

However, quite a lot is calculated if you use the formula above, less will be calculated if you use the method below:

P(effective ≤ 9) = 1 - ( P(effective 10) + P(effective 11) + P(effective 12) )

Let's try to start by calculating P(effective 10). P(effective 10) means the probability of being effective for 10 people and ineffective for 2 people. Then the effective probability is raised to the power of 10 and multiplied by the ineffective probability raised to the power of 2.

P(effective 10) = \((\frac{9}{10})^{10} .(\frac{1}{10} )^2\)

P(effective 10) = \(\frac{9^{10} }{10^{12} }\)

P(effective 10) = \(\frac{3486784401}{1000000000000}\)

So does P(effective 11) and P(effective 12)

P(effective 11) = \((\frac{9}{10} )^{11}.(\frac{1}{10})^{1}\)

P(effective 11) = \(\frac{9^{11} }{10^{12} }\)

P(effective 11) = \(\frac{3486784401}{1000000000000}\)

P(effective 12) = \((\frac{9}{10}) ^{12} .( \frac{1}{10} )^0\)

P(effective 12) = \(\frac{9^{12}}{10^{12}}\)

P(effective 12) = \(\frac{282429536481}{1000000000000}\)

So:

P(effective ≤ 9) = 1 - ( P(effective 10) + P(effective 11) + P(effective 12) )

P(effective ≤ 9) = 1 - ( \(\frac{3486784401}{1000000000000}\)+ \(\frac{3486784401}{1000000000000}\)+ \(\frac{282429536481}{1000000000000}\))

P(effective ≤ 9) = 1 - \(\frac{317297380491}{1000000000000}\)

P(effective ≤ 9) = 1 - 0,317297380491

P(effective ≤ 9) = 0,682702619509 ≈ 0,68

The length of the boundary of any closed figure is called its perimeter.

Perimeter is calculated only of 2-dimensional shape, or a 1-dimensional length. This means that shapes like cubes, cones, and cylinders don't have a perimeter.

The perimeter of any shape is calculated by adding up the length of all its sides. A side is referred to as any continuous uninterrupted length of the shape between two points.

A point to be noted is that the perimeter of a circle is calculated by its radius and a mathematical number called pi. This is denoted by π. All other curved sides are calculated in a similar manner as well.

Answer:

First consider the original amount.

Then consider the rate of tax or markup

To find the tax or markup, multiply the rate by the original amount.

To find the total cost, add the tax or markup to the original amount.

Step-by-step explanation:

Example

A phone has a listed price of $790 before tax. If the sales tax rate is 6.5% find the total cost of the phone with sales tax included. Round your answer to the nearest cent as required.

Solution

Step 1:

List price of the phone = $790

Sales tax rate = 6.5%

Step 2:

Sales tax = 6.5% of 790=0.065×790=51.35

Step 3:

Total cost of phone including sale tax = list price + sales tax

= 790+51.35

= $841.35

The result of the equation 4 x + 2 + x = x – 19 is - 5.25.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

There are two kinds of equations: identities and conditional equations. An identity is true for all values of the variables.

Given equation -

4 x + 2 + x = x – 19

Simplify the equation

5x + 2 = x - 19

5x - x = -19 - 2

4x = -21

x = -21 / 4

x = -5.25

Hence, -5.25 is the answer to the equation 4 x + 2 + x = x - 19.

The temperature of the star emitting radiation with a peak wavelength of 670 nm is approximately 4325.37 K.

To get the temperature of a star with a peak wavelength of 670 nm, you can use Wien's Law, which states: T = b / λ_max where T is the temperature of the star, b is Wien's constant (approximately 2.898 x 10^6 nm K), and λ_max is the peak wavelength.
In this case, the peak wavelength (λ_max) is 670 nm. To calculate the temperature (T) of the star, follow these steps:
Step:1. Plug in the values into Wien's Law equation: T = (2.898 x 10^6 nm K) / (670 nm)
Step:2. Divide the constant by the peak wavelength: T ≈ (2.898 x 10^6) / 670
Step:3. Perform the calculation: T ≈ 4325.37 K
So, the temperature of the star emitting radiation with a peak wavelength of 670 nm is approximately 4325.37 K.

For seven hours of landscaping, Company B would be less expensive than Company A.

An equation is defined as any pair of expressions that both contain the equal sign.

Because of this, Company charges $35 per hour and a $250 equipment fee, compared to Company B's $25 per hour and $300 equipment fee.

For t hours of landscaping, Company A will bill the following:

A = 35t + 250 (1) (1)

In a similar vein, Company B bills the following sum for t hours of landscaping:

B = 25t + 300 (2) (2)

Solve equation (1) now with t = 7:

A = 35 (7) + 250

A = 245 + 250

A = 495

So, for 7 hours of landscaping, business A would bill $495.

Similarly, when equation (2) is resolved for t = 7,

B = 25(7) + 300

Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

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

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.
