Answer:

Step-by-step explanation:

A) The equation for the perimeter of a rectangle is given by 2 * (length + width), so we can write the equation for this rectangle as:

2 * (30 + w) = 108

B) To find the width of the rectangle, we can solve for w:

60 + 2w = 108

2w = 48

w = 24

So, the width of the rectangle is 24 cm.

The double integral [tex]\int\limits^a_b {(x+y)} \, dx dy[/tex]over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3) is equal to 22.

Integration can be thought of as the reverse of differentiation, which is the process of finding the rate of change of a function at a given point.

There are two main types of integration: definite and indefinite integration.  The process of integration can be represented symbolically as ∫ (the integral symbol) and the result of an integration is typically represented as an antiderivative. The fundamental theorem of calculus states that differentiation and integration are inverse operations, so the derivative of an antiderivative is the original function.

To evaluate the double integral  [tex]\int\limits^a_b {} \, dx dy[/tex]over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3), we first need to find the limits of integration for x and y.

The x-coordinates of the vertices of the rectangle range from 0 to 4, so the limits of integration for x are 0 to 4. The y-coordinates of the vertices of the rectangle range from 1 to 4, so the limits of integration for y are 1 to 4.

So, the double integral becomes:

[tex]\int\limits^a_b {(x+y)} \, dx dy[/tex] =  (2 × 4² + 8 × 4) - (2 × 1² + 8 × 1) = 32 - 10 = 22.

Therefore, the double integral [tex]\int\limits^a_b {(x+y)} \, dx dy[/tex] over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3) is equal to 22.

The limit of the sum (6xi-3)/n as n approaches infinity is 9, which means that as the number of subintervals in the interval [0,3] becomes larger and larger, the sum of the values (6xi-3)/n approaches 9.

The limit is a concept in mathematics that helps us understand what happens as a function or a sequence approaches a certain value.

In this particular problem, we are looking at the limit of a sum of values as the number of subintervals in the interval [0,3] approaches infinity.

The interval [0,3] is divided into n equal subintervals and a number xi is chosen arbitrarily in the ith subinterval. We then look at the sum of the values (6xi-3)/n for all n subintervals.

Mathematically, we can write this sum as:

S = (6xi-3)/n for i = 1, 2, ..., n

And the limit of S as n approaches infinity can be written as:

lim n -> infinity S = lim n -> infinity (6xi-3)/n

Now, we use the concept of a Riemann Sum to evaluate the limit of this sum. A Riemann Sum is a way of approximating the area under a curve by breaking it down into rectangles and summing their areas.

In our case, we can think of the sum S as a Riemann Sum for the function f(x) = 6x-3 over the interval [0,3]. As n approaches infinity, the width of the subintervals approaches 0, and the sum S approaches the definite integral of f(x) over [0,3].

Using the fundamental theorem of calculus, we can find the definite integral of f(x) over [0,3] as:

∫f(x)dx = 6x^2/2 - 3x evaluated from 0 to 3

And this value is 9, so the limit of S as n approaches infinity is 9.

Step-by-step explanation:

Outliers: In this data set, the value of 501 is an outlier as it is significantly higher than the other values.

Median: To find the median, we arrange the data in order and find the middle value. In this case, since there are an odd number of values, the median is the middle value: 290.

Mean: To find the mean, we add up all the values and divide by the number of values:

(248 + 260 + 267 + ... + 311 + 501) / 21 = 293.67

10% Trimmed Mean: To find the 10% trimmed mean, we delete the bottom 10% of the values (2 values) and the top 10% of the values (2 values) and then find the mean of the remaining values:

(278 + 282 + 284 + 284 + 285 + 287 + 287 + 290 + 290 + 293 + 295 + 296 + 299 + 311) / 15 = 286.87

20% Trimmed Mean: To find the 20% trimmed mean, we delete the bottom 20% of the values (4 values) and the top 20% of the values (4 values) and then find the mean of the remaining values:

(284 + 284 + 285 + 287 + 287 + 290 + 290 + 293 + 295 + 296 + 299 + 311) / 12 = 288.92

The median, mean, 10% trimmed mean, and 20% trimmed mean can be compared to see how resistant each measure is to outliers. The median is the most resistant measure as it only considers the middle value, whereas the mean is the least resistant measure as it considers all values in the data set. The trimmed means are intermediate measures that are more resistant to outliers than the mean but less resistant than the median. In this case, we can see that the 10% trimmed mean is more resistant to outliers than the mean but less resistant than the 20% trimmed mean.

The total number of rows in the Theater after 125 seats are added is 60 rows.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The Outdoor theater currently has 1,375 seats.

If we add 125 new seats then the number of seats are

= 1375 + 125

= 1500

Each row have 25 seats in one row.

Then, the total number of rows in Theater

= 1500/25

= 60 rows.

The function f(x) is linear and equation is y = 4x + 6 where x=0,1,2,3,4

A function is defined as a relationship between a group of inputs that each have one output. A function is a connection between inputs in which each input is associated to exactly one output. Every function has a domain and a co-domain, as well as a range. In general, a function is denoted as f(x), where x represents the input. A function's generic representation is y = f(x).

In mathematics, there are several types of functions. Some examples include:

When there is a mapping for a range for each domain between two sets, this is referred to be an injective function or a one to one function.

Surjective functions, also known as Onto functions, are used when more than one element is transferred from domain to range.

Polynomial function: A function made up of polynomials.

Inverse Functions: A function that may be used to inverse another function.

Now,

For function f(x)=6,10,14,18,22, g(x)=8,10,12,16,22 for x=0,1,2,3,4

f is a function because y increases 4 for each increase of 1 in x

slope = 4

intercept = f(0) =6

Hence Equation is y = 4x + 6 where x=0,1,2,3,4
