A rain gutter is to be constructed of aluminum sheets 12 inches wide. After marking off a length of 4 inches from each edge, thi

marysya [2.9K]

For this problem, I think there is no need for the details of 12 inches width and 4 inches length. This is because an equation is already given. It was clearly specified that A as a function of θ represents the area of the opening. Then, we are asked to find exactly that: the area of opening. Moreover, the value of θ was also given. Therefore, I am quite sure that the initial details given are for the purpose of red herring only.

So, all we have to do is substitute θ=45° to the function given.
A = 16 sin 45° ⋅ (cos 45° + 1)

The angle 45° is a special angle in trigonometry. So, it would be easy to remember trigonometric functions of this angle. Sine of 45° is equal to √2/2 while cosine of 45° is also √2/2.

A = 16(√2/2) ⋅ (√2/2 + 1)
A = 8+8√2
A = 19.31 square inches

<em>Degrees of freedom for independence in chi-square statistic</em>

<em>ν = ( r-1) (s-1) =6</em>

Step-by-step explanation:

<u><em>Explanation</em></u><u>:-</u>

Given data chi-square test for independence is being used to evaluate the relationship between two variables

<em>Given "A" is classified into 3 categories</em>

<em>Second 'B' is classified into 4 categories</em>

In this chi-square test, we test if two attributes A and B under consideration are independent or not

We will assume that

<em>Null Hypothesis : H₀</em>: The two variables are independent

<em>Degrees of freedom in chi-square test for independence </em>

<em>ν = ( r-1) (s-1)</em>

<em>Given data 'r' = 3 and 's' = 4</em>

<em>Degrees of freedom for independence </em>

<em>ν = ( r-1) (s-1) = ( 3-1) ( 4-1) = 2×3 =6</em>

<em>Test statistic</em>

<em> χ ² = ∑ </em> $\frac{(O-E)^{2} }{E}$ <em></em>

Fractions and properties of addition

Softa [21]

Answer:

Associative Property

Commutative Property

Distributive Property

Identity Property

Step-by-step EXPLANATION

ASSOCIATIVE PROPERTY

In this property, irrespective of the regrouping between a number and the addent within a bracket, the sum, value does not change.

For example:

(A + B) + C = A + ( B + C)

COMMUTATIVE PROPERTY

In commutative Property, you will always get thesame results after changing the order or position of the addent.

For example:

A + B = A + B

Also,

A + B = B + A

DISTRIBUTIVE PROPERTY

Basically here, please note that, the sum (addition) of two numbers times a Third one is always equal to the sum of these numbers times the third one.

For Example:

A x (B + C) = AB + AC

IDENTITY PROPERTY

This property is the easiest of all, it simply says that "Add a number to Zero must always be that number".

For example:

A + 0 = A

B + 0 = B

C + 0 = C
