15 greater than y is at least 150

The scatter plot shows negative correlation because as the plotted values of x increase, the values of y generally decrease.

When two variables are said to have negative correlation, it means that they move in the opposite direction from each other. When one variable is increasing, the other variable is decreasing.

The values of x and y in order of x are:

x  3     4    5   6   7   8   9  

y   6     7    5   4   3    4   2

As shown above, when x increases, y generally decreases and when x decreases, y generally increases. This is therefore a negative correlation relationship.

Enter only the number.

The missing number is 36 so that the equivalent ratios become 3:1, so that the option D is correct.

_______________________________

It is given that Elsa used the multiplication table below to write ratios that are equivalent to 12-4 and one number is missing from the given ratios, we need to find that missing number.

Now, first of all let us understand what are equivalent ratios;

When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent.

Furthermore, in the given question we are given one ratio that is;

=> 12:4 which can also be written as,

=> 3:1

Now, let us assume that the other ratio is x:y than;

=> x:y

So, let us compare both the ratios as they are equivalent ratios;

=> x:y = 3:1

To calculate the other ratio, we need to divide it by 12 so that we get the equivalent ratio;

=> x/12 = 12/4

=> x/12 = 3

=> x = 12 × 3

=> x = 36

So,

=> 36/12 = 12/4

=> 3/1 = 3/1

Therefore, the missing number is 36 so that the equivalent ratios become 3:1, so that the option D is correct.

The net change between the given values of the variable is;  - 3x² - 6xh - 3h² + 23

We are given the function;

f(x) = 5 - 3x²

x = 3

x = 3 + h

The net change is just looking for the difference between f(3) and f(3 + h). Thus, we will evaluate the function at x = 3 and x = 3 + h and then calculate f(3 + h) - f(3).

f(3 + h) = 5 - 3(x + h)²

= 5 - 3x² - 6xh - 3h²

f(3) = 5 - 3(3)²

f(3) = 5 - 27

f(3) = -18

According to the given statement the  fraction of pizza did Billy eat for a snack = 1/12

A fraction is a subset of a bigger whole. In arithmetic, the number is expressed as a quotient, which represents the numerator divided by that of the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in both the numerator and the denominator.

A fraction, often known as a fractional number, is used to represent a portion of a whole. Fractions are made up of two numbers: a numerator (the number above the line) as well as a denominator (which is below the line). The denominator is the number of equal pieces that anything is divided into.

Billy had = 2/3 of pizza

later he ate = 1/4

the pizza did Billy eat for a snack =

Now ,

total size of pizza be  = 1

Billy had = 2/3 of pizza

Based on the calculations, the features which are features of the circle include the following:

A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Given the following equation:

x² + 4x + y² - 2y - 4 = 0

x² + 4x + y² - 2y = 4

Next, we would evaluate the equation by using completing the square method:

x² + 4x + 4 + y² - 2y + 1 = 4 + 5

(x² + 2x + 2x + 4) + (y² - y - y + 1) = 9

(x + 2)² + (y - 1)² = 3²

It is common to discuss numbers when writing academic or professional documents.

It may be appropriate to spell out a number with a decimal if you're sharing statistics or explaining a mathematical concept.

Learning how to properly write decimals can help you create documents that meet expectations.

The proper way to convert worded forms into decimals:

Let's do an example.

Twenty-three and six-tenths,

We are given four numbers.

It is easy to see that Twenty-three equals 23.

But what about the decimal?

Decimals in worded form are always after "and," and they always have "th(s)" at the end, rather than what would appear there in regular numbered word form.

So, given "six-tenths," it is pretty simple.

Six-tenths=0.6

The reason for this is that the word "tenths," won't make it 0.16, because, in decimals, we always skip what would be oneths. The reason for this is; is that this only makes sense if there were "oneths," and dividing a "whole" into "oneths" resulted in the "whole"... So that spot was already taken.

Answer:

Table A

Step-by-step explanation:

Note that the curve flattens out between 4 and 6 s

So the average speed is 0( the train is standing still) in the time interval 4-6 s

From the tables we can see that (A) and (D) are the only two tables that have average speed of 0 for 4-6 second interval. So let's eliminate the other two(B and C) and focus on these two

Looking at tables A and D we can see that the average speed in the 0-2 interval is 1.0 for both

So let's focus on the only entry where the tables show different values ie the interval 2-4 = 2s)

Looking at the graph we can see that in the interval 2-4, the train travels from distance of 2m to distance of 3m. In other words it covers a distance of 1 meter ( 3 - 2 ) in 2 seconds

Therefore average speed at this time interval = 1m/2sec = 0.5 m/s

So table A shows the correct average speed

The standard deviation of the sample number is 1.67.

According to the question we have been given a sample of 5 United states tourist.

We need to find the standard deviation of the sample. The formula for the standard deviation is given as :

                      [tex]\sigma[/tex] = √∑( xₙ - u)²/N

   where    σ = standard deviation

                 xₙ = each value of the sample

                 N = number of sample

                  u = mean

First the mean = (7+8+4+9+7)/5

                       =   7

∑( xₙ - u)² = (7 - 7)² + (8-7)² + (4-7)² + (9-7)²+ (7-7)²

                =  0² + 1² + (-3)² + 2² + 0²

                 = 1 + 9 + 4

                 = 14

Substituting the value sin the given formula we get

                σ = √(14/5)

                    = √2.8

                   = 1.67

Real risk free rate = 3%

Inflation Premium = 5%

Nominal risk free rate Rf = Real risk free rate + Inflation Premium = 3% + 5% = 8%

Market risk premium (Rm –Rf) = 5%

Beta = 2

As per CAPM, required rate of return:

According to the given data, It is Transformation of rotation by 180°.

Transformations are changes that appear in the shapes present on a coordinate plane by rotation, reflection or translation. A function, f, that maps to itself is called the transformation, that is if f = X → X'. This transformation can be any one of the translation, rotation, reflection, and dilation or the combination of operations like translation, rotation, reflection, and dilation. The translation is moving a function in a specific direction, rotation is spinning the function about a point, reflection is the mirror image of the function, and dilation is the scaling of a function.

The transformation that rotates each point in the shape at a certain number of degrees around that point is called transformation of rotation. The shape rotates counter-clockwise when the degrees value is positive and it rotates clockwise when the degrees value is negative. The general rules for transformation of rotation about the origin are given below,

To rotate 90º: (x,y) → (-y, x)

To rotate 180º (x,y) → (-x,-y)

To rotate 270º (x,y) → (y, -x)

given data: preimage → image

                   R( -4, 3 ) changes to R'( 4,-3 )

                   S( -1, 3 ) changes to S'( 1, -3 )

                   T( -4, 1 ) changes to T'( 4,-1 )

As we can notice similar trend in the data given in the question like 180° rotation, Thus we can conclude that the coordinate rule and transformation is Transformation of rotation.
