The area of the rectangular farm is 197,600 square meters.

Let's assume the breadth of the rectangular farm is x meters. According to the given information, the length of the farm is 140 meters longer than its breadth, so the length would be (x + 140) meters.

The perimeter of a rectangle is given by the formula P = 2(length + breadth). We can set up the equation as follows:

2(length + breadth) = 1800

Substituting the values, we get:

2((x + 140) + x) = 1800

Simplifying the equation:

2(2x + 140) = 1800

4x + 280 = 1800

4x = 1800 - 280

4x = 1520

x = 1520 / 4

x = 380

Therefore, the breadth of the farm is 380 meters.

Using this value, we can find the length:

Length = x + 140 = 380 + 140 = 520 meters.

The area of a rectangle is given by the formula A = length * breadth. Substituting the values, we have:

Area = 520 * 380 = 197,600 square meters.

Complete question:

A cube has a side length of 1/3 inch.It would take _ blocks with a side length of 1/6 inch to fill the cube.

B)It would take _ blocks with a side length of 1/9 inch to fill the cube.

Answer:

a) 8 blocks

b) 27 blocks

Step-by-step explanation:

Here we need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = \( \frac{1}{3}\)

Therefore,

V =  \( (\frac{1}{3})^3\)

V = = \( \frac{1}{27}\)

Volume of the cube is \( \frac{1}{27}\)

To find volume of the block, let's use the formula:

V = a³

V = \( (\frac{1}{6})^3\)

V = \( \frac{1}{216} \)

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= \(\frac{\frac{1}{27}}{\frac{1}{216}}\)

\( = \frac{1}{27} * 216 \)

= 8

It would take 8 blocks with a side length of 1/6 inch to fill the cube.

B) Here we also need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = \( \frac{1}{3}\)

Therefore,

V =  \( (\frac{1}{3})^3\)

V = = \( \frac{1}{27}\)

Volume of the cube is \( \frac{1}{27}\)

To find volume of the block, let's use the formula:

V = a³

V = \((\frac{1}{9})^3\)

V = \( \frac{1}{729} \)

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= \( \frac{\frac{1}{27}}{\frac{1}{729}}\)

\( = \frac{1}{27} * 729 \)

= 27

It would take 27 blocks with a side length of 1/9 inch to fill the cube.

Answer:

Fast Chicken, because it has a smaller IQR.

Step-by-step explanation:

Fast Chicken is able to estimate their wait time more consistently because it has a smaller interquartile range (IQR) compared to Super Fast Food. The IQR is a measure of the spread of the middle 50% of the data and is calculated as the difference between the third quartile (Q3) and the first quartile (Q1). The smaller the IQR, the more consistent the data is. In this case, the IQR for Fast Chicken is 4.5 (14.5-10) while the IQR for Super Fast Food is 7 (15.5-8.5). Therefore, Fast Chicken has a more consistent wait time estimate.

Range is a measure of the spread of the data, but it only considers the difference between the highest and lowest values in the data set. The range for Fast Chicken is 15 (20-5), and for Super Fast Food, it is 24 (27-3). Although Super Fast Food has a smaller range than Fast Chicken, it does not necessarily indicate that its wait time estimate is more consistent.

Therefore, the answer is Fast Chicken, because it has a smaller IQR.

The area is covered with 1.4 gallons of water per square foot, approximately 5388.9 gallons of water were used.

We use the formula for the area of a circle: A = πr².

The radius can be determined by dividing the diameter, which is 70 feet, by 2. Therefore, r = 35 feet.

To find the area of the circle, substitute the value of r into the formula for the area of a circle: A = πr².
A = πr²
A = π(35)²
A = 3.14 × 1225
A = 3842.5 square feet
We know that this area is covered with 1.4 gallons of water per square foot, so we can multiply the area of the circle by 1.4 to get the total gallons of water used:

Total gallons of water used = A * 1.4
1.4 × 3842.5 ⇒ 5,379.5 gallons.

Therefore, the total gallons of water used is 5,379.5 gallons.

Ace had 0.625 or 62.5 riders two weeks ago.

Now, We can start by setting up a proportion:

fullness = riders / capacity

where the fullness is 62.5% or 0.625,

And, the capacity is 100% or 1 (assuming the bus is completely full at 100%).

Now, We can solve for the number of riders:

0.625 = riders / 1

riders = 0.625 x 1

riders = 0.625

So, Ace had 0.625 or 62.5% riders two weeks ago. If we assume that riders must be a whole number, we can round up to 63 riders.

Each chicken egg is 5

so day 2 and 5 combined is 15

and day 3 is 25

so subtract 25-15 its 10

Answer:

I think pretty sure its 2

Step-by-step explanation:

If you add the eggs from pen 2 and 5 you get 3 eggs in total. Then you gather all the eggs from pen 3 and minus the eggs you got from pen 2 and 5 which would be 5-3 which would then equal 2 eggs in total. I hope this helped :).

The result will provide the test statistic and the p-value. If the p-value is less than 0.05, we would conclude that the normality assumption is violated.

a. To create a data frame called "turkey" with the first column as "Diet" and the second column as "EggWeights," you can use the following code in R:

R

Copy code

Diet <- c(rep("A", 5), rep("B", 5), rep("C", 5))

EggWeights <- c(124, 118, 120, 127, 115, 98, 100, 95, 102, 105, 116, 97, 100, 89, 98)

turkey <- data.frame(Diet, EggWeights)

b. To test the normality assumption using the Shapiro-Wilk test, you can use the following code:

R

Copy code

shapiro.test(turkey$EggWeights)

c. The normality assumption is violated if the p-value from the Shapiro-Wilk test is less than the significance level (typically 0.05). If the p-value is greater than 0.05, we fail to reject the null hypothesis of normality.

Based on the provided data, the Shapiro-Wilk test can be performed in R:

R

Copy code

shapiro.test(turkey$EggWeights)

The result will provide the test statistic and the p-value. If the p-value is less than 0.05, we would conclude that the normality assumption is violated. If the p-value is greater than 0.05, we would fail to reject the null hypothesis and conclude that the data are consistent with normality.

Note: Since the provided data is relatively small, the Shapiro-Wilk test may not have high power to detect departures from normality. However, it can still provide some insight into the normality assumption.

Answer:

A) The percent increase is by 30%.

B) for the original price = 15%.

B2.0) for the existing price (39) = approximately 11.54%.

Step-by-step explanation:

A) First, we divide 30 by 100. The result is the amount that 1% would be(0.3). If you multiply it by 30(which will become 30%) it will be 9. And from 30-39 is 9.

B) First we divide 30 by 100. The result is the amount that 1% would be(0.39). then if you multiply it by 11.54(which will become 11.54%) it will be 4.50(approximately because it actually is 4.5006 and there is no amount that ends up in 4.50). But if you are asking what percentage from the original cost(30) it would be 15% of it(because 0.3 * 15 = 4.50).

The correct answer is the numbers are statistics because the numbers were calculated from a sample of city University of New York students and are estimates.

The study of statistics focuses on gathering, organising, analysing, interpreting, and presenting data. It is customary to initiate with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.

Populations which can refer to a variety of groupings of individuals or things, such as "every individual living in a nation" or "each atom making up a crystal."

Every facet of data which includes the planning of data collecting in terms of the layout of surveys and experiments, is covered by statistics.

When census data cannot be gathered, statisticians devise specialised experiment designs and survey samples to get data. A representative sample ensures that generalisations and inferences from the sample to the entire population are reasonable.

Isotopes with long half-lives are not useful for dating fossils or rocks that span the last glacial-interglacial cycle (approximately between 12,000 and 125,000 years old) because their decay rates are too slow to provide accurate age determinations within that time range.

Isotopes with long half-lives, such as uranium-238 (with a half-life of about 4.5 billion years) and potassium-40 (with a half-life of about 1.3 billion years), are commonly used for dating much older geological events. These isotopes undergo radioactive decay at a slow rate, which makes them suitable for dating processes spanning millions or billions of years.

However, when it comes to dating fossils or rocks that fall within the last glacial-interglacial cycle (12,000 to 125,000 years old), the long half-lives of these isotopes pose a problem. The time scale of this cycle is relatively short compared to the decay rates of isotopes with long half-lives. As a result, the remaining isotopic ratios or concentrations after such a short time period may not provide precise age estimates, making them less reliable for dating within this specific range.

200 number of students brought their lunch to school on Thursday.

A Percentage is a number or ratio that can be expressed as a fraction of 100.

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.

Percentage formula = (Value/Total Value) × 100

P% of Number = X

where X is the required percentage.

If we remove the % sign, we need to express the above formula

P/100 × Number = X

Given:

Total number of students in school = 800

25% students bring their lunch every day.

25% of 800

= \(\frac{25}{100} \times 800\)

= 25 × 8

The coordinates of D are (2.5, 0).

The coordinates of E are (7.5, 2).

The coordinates of F are (5, 4).

The calculated slope and distance of DF match half the slope of AC (1/5) and half the length of AC (2.36), respectively

To find the coordinates of the endpoints of each midsegment of triangle ABC, we need to calculate the midpoints of the three sides.

Given the coordinates of the vertices:

A(0, 2)

B(5, -2)

C(10, 6)

Let's calculate the coordinates of the midpoints and label them as D, E, and F.

Midpoint of AB (D):

To find the midpoint of AB, we average the x-coordinates and the y-coordinates separately.

x-coordinate of D = (x-coordinate of A + x-coordinate of B) / 2 = (0 + 5) / 2 = 5/2 = 2.5

y-coordinate of D = (y-coordinate of A + y-coordinate of B) / 2 = (2 + (-2)) / 2 = 0 / 2 = 0

So, the coordinates of D are (2.5, 0).

Midpoint of BC (E):

x-coordinate of E = (x-coordinate of B + x-coordinate of C) / 2 = (5 + 10) / 2 = 15 / 2 = 7.5

y-coordinate of E = (y-coordinate of B + y-coordinate of C) / 2 = (-2 + 6) / 2 = 4 / 2 = 2

So, the coordinates of E are (7.5, 2).

Midpoint of AC (F):

x-coordinate of F = (x-coordinate of A + x-coordinate of C) / 2 = (0 + 10) / 2 = 10 / 2 = 5

y-coordinate of F = (y-coordinate of A + y-coordinate of C) / 2 = (2 + 6) / 2 = 8 / 2 = 4

So, the coordinates of F are (5, 4).

Now, let's use the slope and distance formula to verify the midsegment theorem for segment DF.

Slope of DF:

slope = (y-coordinate of F - y-coordinate of D) / (x-coordinate of F - x-coordinate of D)

= (4 - 0) / (5 - 2.5)

= 4 / 2.5

= 8 / 5

Distance of DF:

distance = sqrt((x-coordinate of F - x-coordinate of D)^2 + (y-coordinate of F - y-coordinate of D)^2)

= sqrt((5 - 2.5)^2 + (4 - 0)^2)

= sqrt(2.5^2 + 4^2)

= sqrt(6.25 + 16)

= sqrt(22.25)

≈ 4.71

According to the midsegment theorem, the midsegment DF should have half the slope of AC and half the length of AC.

Slope of AC:

slope_AC = (y-coordinate of C - y-coordinate of A) / (x-coordinate of C - x-coordinate of A)

= (6 - 2) / (10 - 0)

= 4 / 10

= 2 / 5

Half the slope of AC:

slope_AC/2 = (2/5) / 2

= 2/5 * 1/2

= 1/5

Half the length of AC:

length_AC/2 ≈ 4.71 / 2

≈ 2.36

The calculated slope and distance of DF match half the slope of AC (1/5) and half the length of AC (2.36), respectively

The drama club must sell at least 74 student tickets in order to meet the show's expenses.

Let's denote the number of student tickets sold as "S".

We know that each student ticket sells for $7.50, so the total revenue from student ticket sales is 7.50S dollars.

We are also given that each adult ticket sells for $10, and 37 adult tickets were sold. Therefore, the revenue from adult ticket sales is 10 * 37 dollars.

The total revenue from ticket sales must be at least $920 to cover the show's costs. Therefore, we can set up the equation:

7.50S + 10 * 37 ≥ 920

Now, we can solve this equation to find the range of possible values for S:

7.50S + 370 ≥ 920

7.50S ≥ 920 - 370

7.50S ≥ 550

S ≥ 550 / 7.50

S ≥ 73.33

Since the number of student tickets must be a whole number, the smallest possible value for S is 74. Therefore, the drama club must sell at least 74 student tickets in order to meet the show's expenses.
