The multiplication table for 4's underlying pattern: To begin with, let your child know that 4 is an even number. Therefore, no matter what number you multiply by 4 .

A list of items in a sequence is one that is ordered (or events).The number of elements in an ordered sequence determines its length (potentially infinite). Arithmetic sequences, geometric sequences, quadratic sequences, and special sequences are the four primary types of sequences that you need to be familiar with. Number sequences are collections of numbers connected by some kind of rule. If you understand the rule, you can determine the numbers that will come after that in the sequence. Each number differs from the other in this case by 6. In this case, the rule for this sequence is to add 6 each time.

given

The multiplication table for 4's underlying pattern: To begin with, let your child know that 4 is an even number.

Therefore, no matter what number you multiply by 4, the result will always have either 0, 2, 4, 6 or 8 at the end.

With the aid of this method, kids will be able to distinguish multiples of 4, which will make learning the table of four much simpler.

The type of dilation that is used here as well as the factor used is given as: enlargement with scale of 2.5. Option 2

Reducing the object's size by dilation is a change. The items are enlarged or shrunk by dilation. An picture that retains the original shape is created by this alteration. The size of the form does differ, though.

The smaller image is resized into a bigger image from what we can see in the images that we have before us.

We would have to divide all sides of the big square with the corresponding sides of the smaller square

20 / 8 = 2.5

15 / 6 = 2.5

Hence we would see that the scale factor that is used here is 2.5. Therefore the dilation that is used is the enlargement with scale factor 2.5. Option 2 is correct

The straight line along which the squared vertical distances from the data points are reduced is known as the regression line. minimization of the squared vertical distance between the points and the line for a straight line.

What does regression line mean?

An estimated linear relationship between two variables, which is known as the real but unobserved linear relationship, is shown by a regression line. A given value for the explanatory variable is used to predict (or estimate) the value of the response variable using the equation of the regression line.

What does the term "regression line" mean?

Regress, which is derived from the Latin verb "regressus" (to go back), is the root of the word "regression" (to something). Regression, in this sense, is a method that enables "going back" from muddled, difficult-to-interpret data to a more understandable and valuable model.

                               The degree to which both variables can move in unison is defined by correlation. Regression, however, identifies how a change in the unit of a known variable (p) affects a variable that is being evaluated (q).

The quadratic equation numerically for [tex]x^{2} + 7x +12 = 0[/tex] is when

x = -4 and x =-3

The equation is  [tex]x^{2} + 7x +12 = 0[/tex]

To solve this equation using the table, we change the equation into a function

So, the function is F(x) = y = [tex]x^{2} + 7x + 12[/tex]

We have to find the value of x which we can substitute to the equation to get the y value to become 0. Since it is a quadratic equation, x will have 2 values, on [tex]x^{2}[/tex] & 7x

X         [tex]x^{2} + 7x + 12[/tex]  = Y

-4     = [tex]-4^{2}[/tex] +7(-4) + 12 = 0

-3     = [tex]-3^{2}[/tex] +7(-3) + 12 = 0

-2     = [tex]-2^{2}[/tex] +7(-2) + 12 = 2

-1     = [tex]-1^{2}[/tex] +7(-1) + 12  = 6

0     =   [tex]0^{2}[/tex] +7(0) + 12  = 12

1     =   [tex]1^{2}[/tex] +7(1) + 12   = 20

2                 =   [tex]2^{2}[/tex] +7(2) + 12  = 30

Using percentage to determine the ounce of iceberg lettuce in the salad from the pie chart, we have 15.2 ounces

A pie chart is a circular chart that is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. Pie charts are very useful for displaying data and are most commonly used to show percentages or proportional values of different categories relative to the whole.

We can use the concept of percentage to determine the number of ounces of iceberg lettuce present.

In the pie chart, the percentage of ice berg lettuce is 40% and the quantity of salad bought is 38 ounce

40 / 100 = x / 38

0.4 = x / 38

x = 38 * 0.4

The correct option is (B) The line that can be drawn through points D and E is contained in plane Y.

A point is a location in space. It has neither shape nor size. A line is a connected set of points that extends infinitely in two directions. A plane can be defined by three noncollinear points, two parallel lines, or two intersecting lines.

The planes X and Y and points C, D, E and F are shown in the given figure.

We are to select the TRUE statement about the points and the planes.

We know that, if two points lie in a plane, then the line drawn through the points will contain in the same plane.

The points C lies outside the plane Y and the point D lies on the plane Y, so the line drawn through the points C and D will not contain in plane Y.

So, option (A) is NOT correct.

The points D and E, both lie in the plane Y, so the line drawn through the points D and E will also contain in plane Y.

So, option (B) is CORRECT.

Since the plane X contain infinitely many points, so F is not the only point that can lie in plane X.

So, option (C) is NOT correct.

Similarly, there are infinitely many points in the plane Y, so the points D and E are not the only points that can lie in plane Y.

Step-by-step explanation:

The scale factor used in the dilation of the triangle ABC is 3.

Dilation is a method for generating analogous figures decreasing or increasing their dimensions by some scaling factors.

By dividing distances by the scale factor, each point is stretched outward from the central point D if the scaling factor is more than 1 or inwards if the scale factor is less than 1.

Considering the triangle ABC:

The length of the side AB is 2 units

Compared with triangle DEF, the length of the similar side DE is 6 units

The scaling factor = length of side DE /length of the side AB
