How much money is pictured below?

Answer:

3000

Step-by-step explanation:

8 x 375 = 3000

Answer:

4.81 meters

Step-by-step explanation:

1 m = 100 cm

where m = meters

         cm = centimeters

481 centimeters need to be converted:

= 481 cm × [tex](\frac{1 m}{100 cm})[/tex]

The cm in the numerator and denominator will completely cancel each other out:

= [tex]\frac{481}{100}[/tex] m

= 4.81 meters

Answer:

20

Step-by-step explanation:

lets say width is 2x and the length is x

2x+x+2x+x=120

6x=120

x=20

thus, your answer is 20

The number of biology textbooks sold =  156

The number of psychology textbooks sold = 95

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Let x be the number of biology textbooks sold. Then, the number of psychology textbooks sold was x - 61.

The combined total of the two types of textbooks sold was 251, so we can write an equation:

x + (x - 61) = 251

Expanding the right side:

2x - 61 = 251

Adding 61 to both sides:

2x = 312

Dividing both sides by 2:

x = 156

the number of psychology textbooks sold =  x - 61

                                                                      =  156 - 61

                                                                      =  95

So, 156 biology textbooks were sold and 95 psychology textbooks were sold.

The calculation of uncertainty depends on various factors, including the method used, the distribution of the data, and the number of data points. In some cases, the calculated uncertainty may be lower than the actual deviation of the data, especially if the data is not normally distributed or if the number of data points is small.

It's also important to keep in mind that uncertainty is a measure of the spread of the data, not the absolute deviation from the mean. In other words, if the data is tightly clustered around the mean, the calculated uncertainty will be low, even if the maximum deviation from the mean is relatively high.

If you think your calculated uncertainty is not accurately representing the spread of your data, you may want to consider using a different method for calculating uncertainty, or checking the underlying assumptions of the method you are using to ensure that it is appropriate for your data set.

The uncertainty of a group of data represents the range of possible values that the data could reasonably have and is not expected to exceed the actual mathematical value of the data.

The uncertainty of a group of data is determined by factors such as measurement error and natural variability in the data & represents the range of possible values that the data could reasonably have. It is not expected to exceed the actual mathematical value of the data because the mathematical value represents the best estimate of the true value based on the available data.

The uncertainty is a measure of the limitations and potential sources of error in the data and helps to quantify the level of confidence that can be placed in the mathematical value.

The original purchase price of the car before any of the discounts and taxes is,

⇒  $15,024

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

There is a 12% discount because of the Happy Easter Sale and another 5% discount because the purchaser is a valued customer. After these discounts the GST increases the price by 10%.

Here, the customer paid $14 000.

Now, Let the original price = x

Hence, We can formulate;

⇒ x - (12% of x) - 5% of x + 10% of x = 14,000

⇒ x - 12x/100 - 5x/100 + 10x/100 = 14,000

⇒ (100x - 12x - 5x + 10x) / 100 = 14,000

⇒ 93x/100 = 14,000

⇒ 93x = 1400000

⇒ x = $15,024

Thus, The original purchase price of the car before any of the discounts and taxes is,

A database is a collection of organized data stored and retrieved electronically. It is designed to allow efficient storage, retrieval, manipulation, and management of large amounts of data. Databases can be used to store information such as text, numbers, images, and other media. The data in a database is typically organized into tables, which are made up of rows and columns. Each row represents a single record, and each column represents a field of information within that record. There are many different types of databases, including relational databases, NoSQL databases, and in-memory databases, and they are used in a wide range of applications, such as online retail, finance, healthcare, and more.

The Patient-Sport table is used to connect the patient to the sport they are playing. This allows for multiple sports to be assigned to a single patient. In this way, you can track the sports played by each patient, while still maintaining the relationships between the patient and their data in the other tables.

The missing words in the statement are mean and absolute deviation respectively.

The mean absolute deviation (MAD) is a measure of the average magnitude of the differences between individual values in a data set and the mean of the data set. It is calculated by first finding the absolute value of the difference between each data point and the mean, summing these absolute values, and then dividing by the number of data points. The resulting value provides a measure of the "typical" or average deviation of individual data points from the mean, without considering the direction of the deviation (positive or negative). The mean absolute deviation is often used as a summary statistic for data that is not normally distributed or when the variance or standard deviation are not meaningful.

The mean of the absolute deviation between the mean of the data set and the individual numbers in the data set is referred to as the mean absolute deviation (MAD).

Cynthia's percent error in her fourth lab report was 4.38%.

Percent error is a measure of the accuracy of a numerical result, expressed as a percentage of the difference between the actual value and the calculated or measured value. It is calculated using the formula -

Percent Error = (|Actual value - Calculated value| / Actual value) * 100

In order to calculate Cynthia's percent error, we will use the formula:

Percent Error = (|Accepted Value - Measured Value| / Accepted Value) * 100%

For the mean of her four measured values (0.7325), the percent error would be:

Percent Error = (|0.77 - 0.7325| / 0.77) * 100% = 4.38%

The perimeter and area of the figure are 40.8 units and 110 square units respectively.

From the question, we have the following parameters that can be used in our computation:

The figure

Using the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²],

where d is the distance between the points (x₁, y₁) and (x₂, y₂).

So, we have

AB = √[(8-8)² + (9-2)²] = 7

BC = √[(3-8)² + (13-9)²] = 6.4

CD = √[(-3-3)² + (9-13)²] = 7.2

DE = √[(-3+3)² + (9-13)²] = 9

EA = √[(8+3)² + (2-0)²] = 11.2

DB = √[(8+3)² + (9-9)²] = 11

Perimeter = AB + BC + CD + DE + EA.

Perimeter = 7 + 6.4 + 7.2 + 9 + 11.2

Perimeter = 40.8 units.

The figure is observed to be a trapezium ABDE and a triangle BCD.

Triangle BCD have base length DB = 11 with height from C to DB equal to 4.

Trapezium ABDE have sides AB and DE parallel to each other, and height DB = 11.

area of triangle BCD = 1/2 × 11 × 4 = 22 square units

area of trapezium ABDE = 1/2 × (7 + 9) × 11 = 88 square units

Total area ABCDE = 22 + 88

Total area = 110 square units

Hence, the perimeter and area of the figure are 40.8 units and 54 square units respectively.
