Select the correct reason for statement number 5.

The correct option regarding the correlation coefficient of the data-set is given as follows:

C. As budgets increased, the gross revenue increased; r = 0.62.

The correlation coefficient is an index between -1 and 1 that measures the relationship between two variables, as follows:

The coefficient is obtained with a correlation coefficient calculator, inserting the points of the data-set into the calculator.

From the table given by the image, the points are given as follows:

(0.3, 2.05), (0.25, 0.39), (0.2, 1.35), (0.2, 1.24), (0.2, 0.63), (0.18, 0.79), (0.18, 0.53), (0.18, 0.35).

Inserting these points into a calculator, the value of the coefficient is given as follows:

r = 0.62.

Meaning that there is a positive relation amount the variables, and option C is correct.

Option D would be correct if 0.62 was the slope of the line of best fit, hence this is not the case.

The proof of the diagonals of the rectangle are congruent, is given.

When two figures or objects in geometry have the same forms, sizes, or are mirror images of one another, they are said to be congruent.

We have the parallelogram SPQR.

And SQ is the diagonal.

d(S,P) = √(0-0)² + √(b-0)²

d(S,P) = √b²

d(S,P) = b

So, distance SP = b

d(P, Q) = √(a-0)²+ √(b-b)²

d(P, Q) = √a²

d(P, Q) = a

So, distance of  PQ = a

SQ = c²= a² + b²

SQ = √(a² + b²)

The asymptotes for the given function are y = 1 and x = 4 respectively.

An asymptote to any function can be defined as a line that touches the graph of the function as the coordinates of the graph approaches infinity.

[tex]\lim_{x \to \infty}[/tex]The given function is R(x) = (x² - 25)/(x² - 8x + 16)

Since, the given function is not defined at  x² - 8x + 16 = 0.

The values of x can be found as below,

x² - 8x + 16 = 0

⇒ (x - 4)² = 0

⇒ x = 4

Now, [tex]\lim_{x \to \ 4}} R(x)[/tex] = [tex]\lim_{x \to \ 4}[/tex] (x² - 25)/(x² - 8x + 16)

                              = -9/0

                              = -∞

Hence, at x = 4 the function has a y asymptote.

Again, in order to find x asymptotes compute the following limit,

[tex]\lim_{x \to \infty} R(x)[/tex] = [tex]\lim_{x \to \infty}[/tex] (x² - 25)/(x² - 8x + 16)

Apply L' Hospital rule to get,

[tex]\lim_{x \to \infty}[/tex] (x² - 25)/(x² - 8x + 16) =  [tex]\lim_{x \to \infty}[/tex] 2x/ (2x - 8)

⇒ [tex]\lim_{x \to \infty}[/tex] 2/2 = 1

Thus, the x asymptote of the function is at y = 1.

Hence, the horizontal and vertical asymptotes of the given function are  y = 1 and x = 4 respectively.

The fraction of a box that can be filled with the leftover textbooks is 10.

What is a fraction?

A fraction is a number that represents a part of a whole or a part of a collection. It is written in the form a/b, where a is called the numerator and b is called the denominator.

To find the fraction of a box that can be filled with the leftover textbooks, we need to first find the total number of textbooks that are leftover. We can do this by subtracting the number of fourth-grade textbooks and the number of fifth-grade textbooks from the total number of textbooks that can fit in a box:

Leftover textbooks = (28 textbooks/box) - (125 textbooks) - (191 textbooks)

= 28 textbooks - 125 textbooks - 191 textbooks

= -288 textbooks

Since there are -288 leftover textbooks, we can fill -288/-28 =-288/-28=10 boxes with the leftover textbooks.

Hence, the fraction of a box that can be filled with the leftover textbooks is therefore 10/1 = 10.

The fraction of a box that can be filled with leftover textbooks is 125/7

What is the fraction?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

To find the fraction of a box that can be filled with leftover textbooks,

we need to first determine the total number of textbooks that will fit in a box.

Since a box can hold 28 textbooks, and the school has bought 125 Fourth Grade math textbooks and fifth-grade math textbooks,

the total number of textbooks the school has is 125 + 125 = 250 textbooks.

To find the fraction of a box that can be filled with leftover textbooks,

we can divide the total number of leftover textbooks by the total number of textbooks that fit in a box.

Since there are 250 leftover textbooks and a box can hold 28 textbooks, the fraction of a box that can be filled with leftover textbooks is 250/28.

Simplifying this fraction, we get:

250/28 = (250/14)/(28/14) = (250/14)/2 = 125/7

Therefore, the fraction of a box that can be filled with leftover textbooks is 125/7.

Shahina can make apple crumble for 6 people with 550g of apple

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

For 8 people it is:

700g of apple, 40g butter, 240g sugar and 180g flour

This means that the grams of apple for 1 person is

Apple unit rate = 700g of apple/Number of people

Substitute the known values in the above equation, so, we have the following representation

Apple unit rate = 700g of apple/8

For 6 people, we have the following equation

Amount = Apple unit rate * Number of people

Substitute the known values in the above equation, so, we have the following representation

Amount = 6 * 700g of apple/8

Evaluate

Amount = 525g of apple

525g of apple is less than 550g of apple

the value of y is 3 when the value of x is 8.

what is proportional relationship?

When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant.

Given x and y will have a proportional relationship if the ratio of x to y will be equal for all given values.

Given y is inversely proportional to x

When x=3, y=1/x = 8

So when x = 8 the value of y =3

b) The compound interest for the first period is $ 114.125 and the amount is $ 18,374.125

The compound interest for the second period is $ 114.83828125 and the amount after second period is $ 18,488.96

What is Compound Interest?

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

a)

Let the principal be P = amount after first period =  $ 402

Now , the rate of interest r = 6 %

The compound interest is calculated by compounding monthly

Now , the interest for the second period = ( PRT / 100 x 12 )

Substituting the values in the equation , we get

The interest for the second period = ( 402 x 6 x 1 ) / 1200

The interest for the second period = $ 2.01

The amount after the second period = amount after first period +  interest for the second period

The amount after the second period = 402 + 2.01

The amount after the second period = $ 404.01

b)

Let the principal be P = $ 18260

The rate of interest r = 2.5 %

The compound interest is calculated by compounding quarterly

Now , the interest for the first period = ( PRT / 4 x 100 )

Substituting the values in the equation , we get

The interest for the first period = ( 18260 x 2.5 ) / 400

The interest for the first period = 45650 / 400

The interest for the first period = $ 114.125

The amount for the first period = 18260 + 114.125

The amount for the first period = $ 18,374.125

Now , the principal for the second period = interest + amount of first period

The principal for the second period = $ 18,374.125

The rate of interest = 2.5 %

The interest for the second period = ( PRT / 4 x 100 )

Substituting the values in the equation , we get

The interest for the second period = ( 18374.125 x 2.5 ) / 400

The interest for the second period = 45935.3125 / 400

The interest for the second period = $ 114.83828125

The amount for the second period = 18,374.125+ 114.84

The amount for the second period = $ 18,488.96

Subtraction : (-) The result of subtraction is the “difference”

e.g. Subtraction of a and b = a-b

                                            = -2.

Multiplication : (*) The result of multiplication is the “product”

e.g. Multiplication of a and b = 3*4

                                                = 12

Division : (/) The result of division is the “quotient”

e.g. Division of 4 and 2 is = 4/2
