Answer:

Coefficient of Correlation

Step-by-step explanation:

Coefficient of Correlation is a value that ranges between -1 to 1, which is used to denote the closeness or linear relationship between two variables.

The closer the value of the coefficient is to -1 or 1, the stringer the relationship that exists between two variables.

A negative value suggests a negative relationship. Which means, as one variable decreases, the other variable increases.

A positive coefficient of correlation shows a positive relationship between two variables. Which means, as one variable increases, the other also increases.

If the Correlation coefficient is 0, it means there's no relationship between the variables.

Answer:

y=-6x-60

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-9,-6) and has a slope of -6.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -6. So you can right away fill in the equation for a line somewhat to read:

y=-6x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-9,-6). When x of the line is -9, y of the line must be -6.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -6 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-9,-6).

So, why not plug in for x the number -9 and for y the number -6? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-9,-6). y=mx+b or -6=-6 × -9+b, or solving for b: b=-6-(-6)(-9). b=-60.

The total area of all four white boards is 84 square feet, obtained by multiplying the dimensions of one board (7ft × 3ft) by the number of boards (4)

Area is the measure of the size of a two-dimensional surface, usually expressed in square units such as square inches, square feet, or square meters.

Square feet is a unit of area commonly used to measure the size of a surface in the US customary and Imperial measurement systems. One square foot is equal to the area of a square with sides of one foot in length.

According to the given information:

Barb covered 4 walls with white boards, and each board measured 7ft × 3ft. To find the total area of all 4 boards, we need to multiply the area of one board by the number of boards:

Total area = area of one board × number of boards

Total area = (7 ft × 3 ft) × 4

Total area = 21 ft² × 4

Total area = 84 ft²

Therefore, the total area of all four white boards is 84 square feet.

Answer:

Find the value of sin 135.

We have to find the value of sin 135º

Solution

sin(135) can be expressed as = sin (90 + 45)

Using the identity sin(A + B) = sin(A)cos(B) + cos(A)sin(B) we will expand the above sin value

= sin (90 + 45) = sin(90)cos(45) + cos(90)sin(45)

On substituting the known values we get

= ( 1 x 1/√2) + (0 x 1/√2)

= 1/√2

= 0.7071067. . .

Answer

Hence the value of sin 135º=  1/√2 or sin 135º= 0.7071067.

Step-by-step explanation:

this would be correct.

The required value of  sin 45° and sin 135º is \(\frac{\sqrt{2} }{2}\)  and \(\frac{1}{\sqrt{2} }\).

The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.

Given:

The given right triangle having it sides are 1 ,1, \(\sqrt{2}\).

According to given question we have

By the formula of trigonometry we get ,

This is a common value, in which

sin 45º=\(\frac{1}{\sqrt{2} }\)

We can now rationalize the fraction, which comes out to:

=

\(\frac{1}{\sqrt{2} } *\frac{1}{1} \\\\=\frac{1}{\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2} }\\\\=\frac{\sqrt{2} }{2}\)

The common value of sin(135) can be expressed as

= sin (90 + 45)

By using the identity

sin(A + B) = sin(A)cos(B) + cos(A)sin(B)

= sin (90 + 45) = sin(90)cos(45) + cos(90)sin(45)

On substituting the known values we get,

\(= ( 1 * \frac{1}{\sqrt{2} } ) + (0 *\frac{1}{\sqrt{2} } )\\=1/\sqrt{2.\)

Therefore, the required value of  sin 45° and sin 135º is \(\frac{\sqrt{2} }{2}\)  and \(\frac{1}{\sqrt{2} }\).

The equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.

To calculate the equivalent ratio of 1.25 : 3.75 : 7.5, we need to find a common multiplier that can be applied to all the numbers in the ratio to make them whole numbers. In this case, the common multiplier is 4 because it can be multiplied to each number to eliminate the decimals.

By multiplying each number in the ratio by 4, we get:

1.25 * 4 = 5

3.75 * 4 = 15

7.5 * 4 = 30

So the equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.

This means that the relative sizes or quantities represented by the original ratio are maintained in the equivalent ratio. For example, if we had 1.25 units of something, it would be equivalent to 5 units in the new ratio, and if we had 7.5 units, it would be equivalent to 30 units in the new ratio.

Therefore, the answer is open angled bracket -9, 15 close angled bracket.

Thank you, I hope this was useful.

The operation here is vector subtraction. Subtract values from vector 'u' from corresponding values in vector 'v'. The resultant vector of 'v - u' is open angled bracket negative 9 comma 15 close angled bracket.

To solve the problem, you should understand that the operation performed here is vector subtraction. Let's subtract vector u from vector v.

First, subtract each corresponding pair of values from the two vectors. That is, subtract the horizontal (x) values, and then the vertical (y) values. So, in this case, you subtract the value of u's x (5) from v's x (-4) to get -4 - 5 = -9. Then, subtract u’s y (-8) from v’s y (7) to get 7 - (-8) = 15.

Therefore, the result of the subtraction of vectors v - u equals to open angled bracket negative 9 comma 15 close angled bracket, which is the first option in your given choices.

The expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2) Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

The property of exponents that must be applied to the expression p^(1/2) to derive p as the result is the Power of a Power Property.

The Power of a Power Property states that when a power is raised to another power, the exponents are multiplied.

For instance, consider the expression p^(1/2). We can apply the Power of a Power Property to this expression as follows: p^(1/2) = (p^(1/2))^1 By applying the Power of a Power Property, the exponent (1/2) is multiplied by the exponent 1, giving a result of 1/2.

Therefore, the expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2)Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

So we have derived p as the result using the Power of a Power Property.

In summary, we must apply the Power of a Power Property to the expression p^(1/2) to derive p as the result.

For the given functions of x Table 2 is a one to one function. Table 2 is not a one to one function. Table 3 is not a one to one function.

A one-to-one function is one in which every distinct input (or x-value) corresponds to a distinct output (or y-value). To put it another way, no two distinct inputs may result in the same outcome. Also, the same input cannot result in more than one output.

Injective functions are another name for one-to-one operations. They are crucial in many branches of mathematics, such as geometry, algebra, and calculus. A function's inverse, or new function that "undoes" the previous function by flipping the input and output variables, is defined in particular using one-to-one functions.

Table 1:

Because each x-value corresponds to a distinct y-value and each y-value to a unique x-value, Table 1 depicts y as a function of x and is one-to-one.

Table 2:

Because there are two separate y-values associated with the x-value of 10, Table 2 does not show y as a function of x. (8 and 12).
