Answer:

It is not

Step-by-step explanation:

Explanation:

Using a calculator, we find that

sqrt(1815) = 42.6028168082816

which is not a whole number. The decimal numbers go on forever without any known pattern. Therefore, this number is irrational. This means it is not rational.

Answer:

La cantidad que Javier paga como impuesto, A es de 1.200 €

La cantidad que Antonio paga como impuesto, B es 900 €

El importe que paga Elvira como impuesto, C es de 1.000 €

Step-by-step explanation:

Dejemos que 'A', 'B' y 'C', representen la cantidad que pagan Javier, Antonio y Elvira respectivamente, y que 'k' represente la constante de proporcionalidad, por proporcionalidad inversa, tenemos;

A = k / 1500, B = k / 2000, C = k / 1800

A + B + C = 3100

∴ k / 1500 + k / 2000 + k / 1800 = 3100

Simplificando la ecuación anterior usando una calculadora gráfica da;

31 · k / 18 000 = 3100

k = 18.000 × 3.100 / 31 = 1.800.000

k = 1.800.000

La cantidad que Javier paga como impuesto, A = 1.800.000 / 1.500 = 1.200

La cantidad que Antonio paga como impuesto, B = 1.800.000 / 2.000 = 900

La cantidad que paga Elvira como impuesto, C = 1.800.000 / 1.800 = 1.000

Answer: D. y-5= -7(x-8)

Step-by-step explanation:

point slope form: y-y1=m(x-x1)

slope= -7

point: (8,5)

use the slope and point and plug it into point slope form equation.

y-5= -7(x-8),

The Answer would be D. y-5= -7(x-8)

The two-digit number in which the tens digit of the number is one more than the units digit is 54.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Let the unit digit be x. The tens digit of a two-digit number is one more than the units digit. Thus the unit digit is,

\(\rm \;tens\; digit=x+1\)

Then the number is,

\(10(x+1)+x\\11x+10\)

The reverse of this number is,

\(10x+x+1\\11x+1\)

The difference between this number and the reverse number is 1/5 of the reverse number. Thus,

\(11x+10-(11x+1)=\dfrac{1}{5}(11x+1)\\9=\dfrac{1}{5}(11x+1)\\45=11x+1\\x=\dfrac{44}{11}\\x=4\)

The unit digit is 4. Thus the tens digit is,

\((x+1)=4+1\\(x+1)=5\)

Hence, the two-digit number in which the tens digit of the number is one more than the units digit is 54.

2(4.8) = 9.6 girls

In the book "Sarah, Plain and Tall" by Patricia MacLachlan, Anna, one of the main characters, describes what she thinks the prairie looks like after the hail storm.

After the hail storm, the prairie is likely to have undergone some visible changes. Hail storms can cause damage to crops, vegetation, and the overall landscape. It's possible that Anna perceives the prairie as altered or damaged due to the hail storm.

Given Anna's deep connection to the prairie and her love for the natural world, it is likely that she feels concerned and saddened by the effects of the storm. The prairie holds great significance to Anna and her family, representing their home and way of life. Therefore, she may have mixed emotions of worry and sadness, hoping for the prairie to recover and return to its previous beauty.

Anna's observations and thoughts about the prairie after the hail storm may also reflect her resilient and optimistic nature. Despite the temporary changes caused by the storm, Anna may find solace in the knowledge that the prairie has the ability to heal and rejuvenate over time. She may view it as a natural cycle, understanding that the prairie will eventually flourish once again.

In summary, while the exact thoughts of Anna about the prairie after the hail storm are not explicitly stated in the book, we can infer that she experiences a mixture of concern, sadness, and hope for the prairie's recovery. The book portrays Anna as a character deeply connected to the land, making her emotional response to the storm's impact on the prairie significant and meaningful.

(a) The values of Q1 as 2 and Q3 as 35.

(b) The dataset was arranged in ascending order, and since the total number of observations (n) is odd (13), the median was found to be the middle value, which is 5.

(c) The upper adjacent value was determined by adding 1.5 times the IQR to Q3, resulting in 87.5.

(d) The box plot of the data is illustrated below.

(a) Finding Q1 and Q3:

To determine Q1 and Q3 from the given dataset, we can start by arranging the data in ascending order: 0, 2, 3, 4, 4, 5, 6, 7, 35, 2677, 33478.

Next, we count the total number of observations (n) which is 13 in this case. We use the following formulas to calculate the position of Q1 and Q3:

Q1 = (1 * n) / 4

Q3 = (3 * n) / 4

Substituting the value of n into the formulas:

Q1 = (1 * 13) / 4 = 3.25 (approximately)

Q3 = (3 * 13) / 4 = 9.75 (approximately)

Now, we need to identify the values in the dataset that correspond to these positions. For Q1, we take the value at the position immediately below 3.25, which is 2. For Q3, we take the value at the position immediately below 9.75, which is 35.

Therefore, the values of Q1 and Q3 for the given dataset are 2 and 35, respectively.

(b) Finding the Median:

The median represents the middle value of a dataset when it is arranged in ascending or descending order. If the dataset has an odd number of observations, the median is the middle value itself. If the dataset has an even number of observations, the median is the average of the two middle values.

Arranging the given dataset in ascending order: 0, 2, 3, 4, 4, 5, 6, 7, 35, 2677, 33478.

Since the total number of observations (n) is odd (13), the median will be the middle value. In this case, the middle value is the 7th observation, which is 5.

Therefore, the median for the given dataset is 5.

(c) Finding the Adjacent Values:

Adjacent values, also known as whiskers in a boxplot, indicate the minimum and maximum values within a certain range. The range is determined using the interquartile range (IQR), which is the difference between Q3 and Q1.

For the given dataset, the IQR is calculated as follows:

IQR = Q3 - Q1 = 35 - 2 = 33

The adjacent values are determined by extending the whiskers 1.5 times the IQR below Q1 and above Q3.

Lower adjacent value = Q1 - 1.5 * IQR

Upper adjacent value = Q3 + 1.5 * IQR

Substituting the values:

Lower adjacent value = 2 - 1.5 * 33 = -47.5

Upper adjacent value = 35 + 1.5 * 33 = 87.5

Therefore, the adjacent values for the given dataset are -47.5 and 87.5.

(d) Determining the Correct Modified Boxplot:

To determine the correct modified boxplot, we need additional information or options to compare against the given dataset. Unfortunately, the options are not provided in your question. Please provide the options or any additional information related to the modified boxplot so that I can assist you further in choosing the correct one.

Remember, the boxplot is a graphical representation of the dataset using its quartiles, median, adjacent values, and outliers, if any. It provides a visual summary of the distribution and identifies any potential outliers or extreme values.
