Answer:

Area of the rectangle = 95 cm²

Step-by-step explanation:

Perimeter of the rectangle = Sum of the measures of the sides of the rectangle

From the figure attached,

Perimeter of the rectangle = 2[(3x -1) + (2x + 3)]

                                       39 = 2(5x + 2)

                                       39 = 10x + 4

                                      10x = 39 - 4

                                      10x = 35

                                          x = 3.5

Therefore, measure of the given sides will be,

Length = (3x - 1) cm

3x - 1 = (3×3.5) - 1

        = 10.5 - 1

        = 9.5 cm

Width = (2x + 3) cm

2x + 3 = (2×3.5) + 3

          = 7 + 3

          = 10 cm

Area of the rectangle = Length × width

                                   = 9.5 × 10

                                   = 95 cm²

Therefore, area of the rectangle is 95 cm².

Answer:

t-value = 1.690

Step-by-step explanation:

We are given;

Sample size; n = 36

DF = n - 1

DF = 36 - 1

DF = 35

Confidence level = 90%

However, from the first table I attached, we see that the critical significance level of a 90% Confidence level is 0.05

Thus, in the second table, looking at a DF of 35 and significance level of 0.05, we have a critical t-value = 1.690

The mean absolute deviation for the given dataset of 3, 6, 3.8, 3.2, and 3.4 is approximately 0.996. This means that, on average, each data point in the dataset deviates from the mean by approximately 0.996.

The mean absolute deviation (MAD) measures the average distance between each data point and the mean of the dataset. To find the MAD, you need to follow these steps:

1. Calculate the mean of the dataset by adding up all the numbers and dividing the sum by the total number of data points. In this case, the dataset consists of the following numbers: 3, 6, 3.8, 3.2, and 3.4. Adding them up gives us a sum of 19.4. Dividing this sum by 5 (since there are 5 data points) gives us a mean of 3.88.

2. Find the absolute deviation for each data point by subtracting the mean from each data point and taking the absolute value. For example, for the first data point, 3, the absolute deviation would be |3 - 3.88| = 0.88. Repeat this step for all the data points.

3. Calculate the mean of the absolute deviations by adding up all the absolute deviations and dividing the sum by the total number of data points. In this case, the absolute deviations are: 0.88, 2.12, 0.72, 0.68, and 0.58. Adding them up gives us a sum of 4.98. Dividing this sum by 5 gives us a mean of 0.996.

So, the mean absolute deviation for the given dataset is approximately 0.996.


The mean absolute deviation helps us understand how much each data point varies from the mean of the dataset. By calculating the absolute deviation for each data point and finding the average, we can determine the typical amount of variation in the dataset.


The mean absolute deviation for the given dataset of 3, 6, 3.8, 3.2, and 3.4 is approximately 0.996. This means that, on average, each data point in the dataset deviates from the mean by approximately 0.996.

Approximately 16% of the design is black.

Since the radius of each circle increases by 2 inches, the diameter of each circle increases by 4 inches. Thus, the diameter of the largest circle is 2 + 4(5) = 22 inches.

The area of each circle is proportional to the square of its radius, so the area of the smallest circle is π(\(2^2\)) = 4π square inches. The area of the second circle is π(\(4^2 - 2^2\)) = 12π square inches, the area of the third circle is π(\(6^2 - 4^2\)) = 20π square inches, and so on.

The total area of the design is the sum of the areas of all the circles, which is:

4π + 12π + 20π + 28π + 36π = 100π

The black area in the design consists of four quarter circles, each with a radius of 4 inches. The area of a one-quarter circle is:

(1/4)π(\(4^2\)) = 4π

So the total black area is 4 times this, or 16π.

The percent of the design that is black is:

(16π / 100π) x 100% ≈ 16%

Therefore, approximately 16% of the design is black.

Answer:

The slope of a linear model can be calculated using the formula:

m = Δy / Δx

where:

Δy = change in y (the dependent variable, in this case, total cost)

Δx = change in x (the independent variable, in this case, number of candy bars)

This is essentially the "rise over run" concept from geometry, applied to data points on a graph.

In this case, we can take two points from the table (for instance, the first and last) and calculate the slope.

Let's take the first point (3 candy bars, $6.65) and the last point (25 candy bars, $48.45).

Δy = $48.45 - $6.65 = $41.8

Δx = 25 - 3 = 22

So the slope m would be:

m = Δy / Δx = $41.8 / 22 = $1.9 per candy bar

This suggests that the cost of each candy bar is $1.9 according to this linear model.

Please note that this assumes the relationship between the number of candy bars and the total cost is perfectly linear, which might not be the case in reality.

Answer:

x ≥ 97

Step-by-step explanation:

Average = Sum of values divided by the amount of numbers in a data set

Data Set: {75, 82, 94, 77, ?}

75 + 82 + 94 + 77 + ? = ? ÷ 5 = 85

85 x 5 = 425

75 + 82 + 94 + 77 + ? = 425 ÷ 5 = 85

75 + 82 + 94 + 77 = 328

425 - 328 = 97

Ray must score greater than or equal to 97, or x ≥ 97 in order to have an average of at least 85.

The simplest and most straightforward measure of variability is the range. The range is calculated by subtracting the smallest value in a dataset from the largest value.

It provides a basic understanding of how spread out the data points are. However, the range has limitations as it only considers the extreme values and does not take into account the distribution of the remaining data points.

Therefore, while the range is a simple measure of variability, it is often supplemented or replaced by more robust measures such as the variance and standard deviation, which provide a more comprehensive understanding of the dispersion of data.

The statistics are used to create a visual representation of data distribution, with the box formed by Q1, Q2, and Q3, and the whiskers extending to the minimum and maximum values.

To draw a box plot, you need to have several statistical measures such as the minimum value, the maximum value, the median (or second quartile), the first quartile (Q1), and the third quartile (Q3).

These values are used to create the "box" in the plot, which represents the middle 50% of the data. The lower whisker is drawn from the minimum value to Q1, while the upper whisker is drawn from Q3 to the maximum value. Any data points that fall outside the whiskers are considered outliers and are represented by individual points. The box plot is a useful tool for visualizing the distribution and spread of a dataset.

To draw a box plot, you'll need five key statistics: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. The minimum and maximum represent the lowest and highest data points, respectively. Q1 is the median of the lower half of the data, while Q3 is the median of the upper half. The median (Q2) splits the data into two equal parts. These statistics are used to create a visual representation of data distribution, with the box formed by Q1, Q2, and Q3, and the whiskers extending to the minimum and maximum values.

Answer:

SA= 3603.84cm^2

Step-by-step explanation:

the Surface Area SA is the total area of the sides and the base.

The area of the base= 32*32= 1024cm^2

the area of one of the sides = slant height of pyramid * base edge/2

the slant height l of the pyramid

l= sqrt(16^2+37^2) = 40.31cm

area of the side =( 40.31*32)/2 =644.96cm^2

there are 4 sides so the area of the sides are

4* 644.96=

addig the area of the base we get the Surface Area SA of the pyramid

SA = 2579.84 + 1024 = 3603.84cm^2

A basis for the domain of T such that the matrix for T relative to that basis is diagonal is {1, x}.

To find a basis for the domain of T such that the matrix for T relative to that basis is diagonal, we need to find eigenvectors of T. Since T maps polynomials of degree at most 1 to polynomials of degree at most 1, we consider the polynomials a + bx.

Let's find the eigenvectors of T by solving the equation T(a + bx) = λ(a + bx), where λ is an eigenvalue.

T(a + bx) = a(a + 2bx) = (a^2 + 2abx) = λ(a + bx)

Expanding the equation, we get:

a^2 + 2abx = aλ + bλx

Comparing the coefficients of like terms on both sides, we get the following system of equations:

a^2 = aλ

2ab = bλ

Simplifying the equations, we have:

a(a - λ) = 0

b(2a - λ) = 0

For the matrix to be diagonal, we want distinct

. Let's consider the cases:

Case 1: λ = 0

From the first equation, we have a = 0. This implies b can be any real number. So, one possible eigenvector is b.

Case 2: λ ≠ 0

From the first equation, we have a - λ = 0, which implies a = λ. Substituting this into the second equation, we have 2(λ) b = bλ, which implies b = 0 or λ = 2.

Putting all the cases together, we have two possible eigenvectors: 0 and 2x.

Therefore, a basis for the domain of T such that the matrix for T relative to that basis is diagonal is {1, x}.

Therefore, the number of cats falling from the 5th floor should be the same as the number falling from the 4th floor. The number of cats falling from a higher floor may be greater if there are extra factors, such as wind, that could affect their fall, but the force of gravity does not change with the floor.
