The best prediction the price will do next is keep increasing.

What is stock price?

The price at which one share of a company would be purchased is known as the share price or stock price. A share's price is not constant; rather, it changes over time in response to market factors. It is likely to rise if the business is thought to be doing well or fall if it isn't living up to expectations.

A company's price rising more quickly indicates that investors are supporting the rally and that the stock will rise further.

On the other hand, a declining price trend with high volume suggests a possible downward trajectory. A high trade volume could also indicate a change in trend.

Hence, the best prediction the price will do next is keep increasing.

Mia will pay a total of $4.5 for the shipping and handling of the t-shirt

From the question, we have the following parameters that can be used in our computation:

Cost of the shirt = $15

shipping and handling = 30%

The amount paid for the shipping and handling of the t-shirt can be calculated using the following equation

Amount paid = original price * + shipping and handling

Substitute the known values in the above equation, so, we have the following representation

Amount paid = 15 * 30%

Evaluate the products

Amount paid = 4.5

The approximate distance from the sun to Earth is miles greater than the approximate distance from Earth to the moon by 9.276 × 10^7.

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format.

In this case, the approximate distance from Earth to the moon is 240 thousand miles. This will be 2.4 × 10^5

The approximate distance from Earth to the sun is 93 million miles. This will be:

= 9.3 × 10^7

The difference will be:

= (9.3 × 10^7) - (2.4 × 10^5)

= 9.276 × 10^7

The best way of writing a prolog rule that gives you all the possible coin combinations adding to a dollar is using membership rules and arithmetic condition.

The Prolog interpreter warns that it can only find one occurrence of one or more variables, which is strange, since typically variables are used to perform unification, pass values from one predicate to another, etc.

Arithmetic in Prolog

In arithmetic expression, + - * / symbols are special type of infix operator, and these operators are also known as arithmetic operators. In Prolog, operators are used as predicates but here operators are functions and these operators return a numerical value.

The number of times the point R ( 120° , P ) needs to be rotated so that the figure is mapped to itself is 3 times

What is Rotation?

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the number of rotation be = n

Let the point be R

Now , the coordinates of the point R is

R ( 120° , P )

Now , to map the figure onto itself it needs to rotate 360°

So ,the number of times 120° needs to rotate to reach 360° is calculated as

n x 120° = 360°

Divide by 120 on both sides , we get

n = 360 / 3

n = 3 times

Therefore , the value of n is 3

Hence ,  The number of times the point R ( 120° , P ) needs to be rotated so that the figure is mapped to itself is 3 times

There are 4 lattice points on the line segment whose endpoints (3,17) &(48,281)

What is a Lattice point?

In a Cartesian coordinate system, a lattice point is a point whose x-coordinates and y-coordinates are both integers. A point in a regularly spaced array of points, known as a point lattice, that is at the intersection of two or more grid lines is referred to as a lattice point. Point lattices with unit cells that are square, rectangular, hexagonal, and other forms can be built in a plane. An unspecified point in a square array constitutes a point in a point lattice.

The difference in the y-coordinates is 281 - 17 = 264

the difference in the x-coordinates is 48 - 3 = 45.

The gcd of 264 and 45 is 3,

so the line segment joining (3,17) and (48,281) has a slope [tex]\[\frac{88}{15}\][/tex]

The points on the line have coordinates[tex]\[\left(3+t,17+\frac{88}{15}t\right).\][/tex]

If t is an integer, the y-coordinate of this point is an integer if and only if t is a multiple of 15.

The points where t is a multiple of 15 on the segment [tex]3\leq x\leq 48[/tex] are 3, 3+15, 3+30, and 3+45.

What is the rectangular dimension?

Two dimensions make up a rectangle: the length and, perpendicular to that, the breadth. A triangle's or an oval's interior likewise has two dimensions.

We have,

volume L* W * H = 512 cm³

sides of the box cost = 1 cent/cm²

top and bottom cost 2 cent/cm²

to find out

dimensions of the box that minimize the total cost of material use

we know here,

L* W * H = 512 cm³

where,

L is length and W is width and H is the height

so when we minimize the cost function

C( L, W, H ) = (1) 1 H ( L + W ) + (2) 1 L W

so put here H

substitute  [tex]H = \frac{512}{LW}[/tex] we get,

C(L, W) = 512([tex]\frac{1}{l}, \frac{1}{W}[/tex]) + 2LW

so

minimum cost will be when the two partial derivatives is 0

dC/dL = 2W - 512/L² = 0

so

dC/dW = 2L - 512/W² = 0

L =  256/W²

so

by solving the above equation we get

L = W = (256)⁻³ = 16cm

and

H = 512/16 = 32

H =  32 cm

Hence, the dimensions of the box that minimize the total cost of materials used are:

The area of the polygons arranged in order of increasing Area is:

A polygon is a planar figure characterized by a limited number of straight line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both. A polygonal circuit's segments are known as its edges or sides.

The area of the triangle is given as:

[Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By)]/2

Where Ax and Ay are the x and y coordinates for the vertex of A. The same applies for the x and y notations of the B and C vertices.

Hence given:

A(-4-3), B(1, -3), C(-1,2)

we have

[-4(-3-2) + (1(2-(-3)) + (-1(-2-(-3))]/2

= 24/2

= 12

Hence the area of the triangle is 12.

To calculate the area of the rectangle, we use the distance formula. The equation for this is given as:

d² = (x₂ - x₁)² + (y₂-y₁)²

Where (x₁, x₂) are the coordinates of the first point and

(y₁, y₂) are the coordinates of the second point.

Assuming that the vertices are labeled as follows:

A (7,9), B(6,9), C(6,5), D(7,5), then

AB² = (6-7)² + (9-9)²
AB² = 1 + 0

AB = 1

BC² = (6-6)² + (5-9)²

BC² = 0² + -4²

BC = 4

CD² = (7-6)² +(5-5)²

CD² = 1² + 0²

CD = 1

DA² = (7-7)² + (9-5)²

DA² = 0² +4²

DA = 4

From the above, we can tell as is typical of a rectangle, that AB = CDand BC = DA

Since the Area of the rectangle is AB x CD OR BC x DA

The area of the rectangle =

4 x 1 = 4

Using the distance methods we can also arrive at the length of the sides of the square.

Since the area of a square is given as L² we only need the lenght one one side.

Hence,

AB = 3.60555

Hence the area of the square =

3.60555²

= 12.9999908025

Area of the square [tex]\approx[/tex] 13.

To be more certain that it captures the true value of the population proportion, a 95 % confidence interval must be larger than an 80 % confidence interval.

An area created using fixed-size samples of data from a population (sample space) that follows a certain probability distribution is known as a confidence interval. A selected population statistic is built into the interval with a specified probability. An estimate's level of uncertainty is described by a confidence interval, which is a range of numbers. You have a 5% probability of being incorrect with a 95% confidence interval. You have a 10% chance of being incorrect with a 90% confidence interval.
