The most appropriate choice for slope will be given by -

1) Initially, as x increases, y also increases

2) Slope of the graph between x = 3 and x = 5  is 2

3) Slope of the graph between x = 5 and x = 9  is -1

4) Greatest value of y is y = 4 and it occurs when x = 5

What is slope of a line?

Slope of a line is equal to the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, slope = tan [tex]\theta[/tex]

Suppose  [tex](x_1, y_1)[/tex]  and [tex](x_2, y_2)[/tex]be two points on a line then the slope of the line is calculated by the formula

slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here,

1) Initially, as x increases, y also increases

2) Slope of the graph between x = 3 and x = 5 = [tex]\frac{4 - 0}{5 - 3}[/tex]

                                                                             = [tex]\frac{4}{2}[/tex]

                                                                             = 2

3) Slope of the graph between x = 5 and x = 9 =

                                                                                 [tex]\frac{4 - 0}{5 - 9}\\-\frac{4}{4}\\-1[/tex]

2. Big TV prices Here are prices and screen sizes (in inches, measured diagonally) for 7 different sizes of one brand of LED HD television.47 Use technology to calculate the equation of the least- squares regression line relating y = price to x = screen size. Screen size Price 60 1000 55 800 50 700 47 600 42 430 39 400 32 300

Answers

The general formula for the least-squares regression is:

[tex]y=a+bx_i[/tex]

Where

a represents the y-intercept

b represents the slope

To estimate the y-intercept and the slope of the regression line you have to apply the following formulas:

[tex]b=\frac{\Sigma xy-\frac{\Sigma x\Sigma y}{n}}{\lbrack\Sigma x^2-\frac{(\Sigma x)^2}{n}\rbrack}[/tex][tex]a=\bar{y}-b\bar{x}[/tex]

First, calculate the sums and the means for both variables.

X= screen size

Y= price

Calculate the slope of the line:

[tex]\begin{gathered} b=\frac{\Sigma xy-\frac{\Sigma x\Sigma y}{n}}{\Sigma x^2-\frac{(\Sigma x)^2}{n}} \\ b=\frac{210460-\frac{325\cdot4230}{7}}{15643-\frac{325^2}{7}} \\ b=\frac{210460-196392.85}{15643-15089.29} \\ b=\frac{14067.75}{553.71} \\ b=25.41 \end{gathered}[/tex]

Once you have calculated the slope, you can calculate the y-intercept:

[tex]\begin{gathered} a=\bar{y}-b\bar{x} \\ a=604.29-25.41\cdot46.43 \\ a=604.29-1179.7863 \\ a=-575.23 \end{gathered}[/tex]

For a lower tail test, the p-value is the probability of obtaining a value for the test statistic is at least as small as that provided by the sample.

Probability is the probability that something will happen. Whenever the outcome of an event is uncertain, we can speak of the probability, or likelihood, of a particular outcome. Probabilistic analysis of events is called statistics.

The lower-tailed test is a one-tailed test in which the critical region of the distribution is one-sided (leftmost) and tests whether a sample is less than a specified value.

Area of square with side = 4cm is : 16cm²

Area of rectangle with height = 2cm and width = 3cm is : 6cm²

Explanation :

To find the area of square:

A square is a two-dimensional figure with equal-sized sides. Because all of the sides are equal, the area is length times width, which equals side side. As a result, the area of a square is side square.

                   Area = a×a

                            = a²

To find the area of rectangle :

In the rectangle opposite sides are equal .The area of a rectangle is calculated once the length and width are known. A rectangle's area can be calculated by multiplying its length and width.

                    Area = l x b

Given sides of square a = 4cm .

                   Area = a²

                   Area = 4²

                            = 16 cm²

Given sides of rectangle ,

                 l = 3cm

                b = 2cm

              Area = l × b

                      = 3 × 2

                      = 6 cm²

Area of square  is 16 cm²

Area of rectangle is 6 cm²

What are polynomials?

A polynomial is an expression in mathematics that solely uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of indeterminates and coefficients. The polynomial x2 4x + 7 is an illustration of a single indeterminate x polynomial. Sums of terms with the pattern k x n—where k is any positive integer and n is an arbitrary number—are known as polynomials. A polynomial is something like 3x+2x-5. Polynomials: An introduction In this video, basic terms such terms, degrees, standard form, monomial, binomial, and trinomial are covered. Using mathematical operations like addition, subtraction, multiplication, and division, a polynomial is an equation made up of variables, constants, and exponents (No division operation by a variable).

g(x) = 5x - 6

So,

f(x) = 2(5x - 6)² +  3(5x - 6) + 12

= 2( 25x² + 36 - 60x ) + 15x - 18 + 12

How to simplify the equation?

From the question, the equation is given as

a=1/7(b+c-d-d)

Rewrite the above equation properly

So, we have the following representation

a = 1/7(b + c - d - d)

Evaluate the like terms in the above equation

So, we have the following equation

a = 1/7(b + c - 2d)

Open the brackets in the above equation

So, we have the following equation

a = 1/7 * b + 1/7 * c - 1/7 * 2d

Evaluate the products in the above equation

So, we have the following equation

a = b/7 + c/7 - 2/7d

Convection currents are the heating and cooling cycles of(gases, magma) in the mantle's asthenosphere.2. A boundary is the (edge, middle) of a tectonic plate whereit meets other plates.3. A divergent boundary forms when two tectonic plates(collide, separate).4. A convergent boundary forms when two tectonic plates(explode, collide).5. A transform boundary forms when two tectonic plates slide(into, past) one another.********True/False. Decide if each statement is true or false, and write true or falsein the blank.6. Magma pushes tectonic plates along as it cyclesthrough the mantle.7. Tectonic plates only move by sliding past one another.8. If two oceanic crust plates collide, one is subductedbelow the other.9. When tectonic plates slide past one another, theygrind and may cause earthquakes.10. Tectonic plates move quickly, so boundaries takeonly a few years to form.
