Make a scatter plot and describe the correlation.
(0,11),(2,8),(3,7),(7,2),(8,0)
A scatter plot is a series of points plotted on horizontal and vertical axes. If there is no correlation between variables, the points appear randomly scattered on the coordinate plane. If the correlation is high, the points will be clustered around the straight line. A scatter chart is a data visualization tool that helps show trends.
The scatter plot shows not only the magnitude of the correlation, but also the direction of the correlation.
As the vertical (or Y-axis) variable increases, the correlation is positive as the horizontal (or X-axis) variable increases.
The correlation is negative if the y-axis variable decreases and the x-axis variable increases, or vice versa.
The correlation is zero if none of the above criteria can be established.

Si en la pandemia de 1918 murieron 40 millones ¿Qué porcentaje representa del total de la población mundial de ese año?
La "Gripe Española" de 1.918 acabó con 2.105 por ciento de la población mundial de su tiempo.
¿Cuál es el porcentaje de personas muertas por causa de la "Gripe Española" de 1918?
La "Gripe Española" fue una enfermedad respiratoria emparentada con los virus SARS-COV vistos en las últimas dos décadas que alimentó una pandemia que mató a decenas de millones de personas entre 1.918 y 1.920.
En esta pregunta debemos determinar el porcentaje de personas muertas con respecto a la población mundial de la época. Esto calcula al dividir el número de personas muertas por el número total de pobladores del mundo y multiplicar tal razón por 100.
La población aproximada del mundo en 1.920 fue de casi 1.900 millones de personas, entonces tenemos que el porcentaje de personas muertas es:
x = (40 000 000 / 1 900 000 000) × 100
x = 2.105 %

Write an equation of each line in standard form with integer coefficients. y=1/2 x-2
The equation of the given line y=1/2 x-2 in standard form is x - 2y - 4 = 0
Equation of a line in standard form can be expressed as:
Ax + By + C = 0
Where:
A and B are called coefficients.
x and y are called variables of degree 1 or linear variables.
C is called a constant.
In the above equation, the values of A, B, and C should be integers, not fractions or decimals. Furthermore, "A" needs to be a positive number.
The given equation is:
y = 1/2 x - 2
Notice that the coefficient of x is not an integer, therefore we need to multiply the equation by 2.
2y = 2 . (1/2)x - 2 . 2
2y = x - 4
Subtract x from both sides
2y - x = x - 4 - x
-x + 2y = -4
Add 4 to both sides
-x + 2y + 4 = -4 + 4
-x + 2y + 4 = 0
Note that the coefficient of x is negative, hence, we need to multiply both sides by (-1).
x - 2y - 4 = 0
This is the standard form of the given line.

According to Heron's Formula, if the lengths of the sides of a triangle are a, b and c, and s= (a + b + c)/2,
then the area, A, is given by the formula: A = √s(s-a) (s-b) (s-c). Find the area of a triangle whose
sides are 6ft, 7ft and 11ft.
O A = 21.1 ft²
O A = 18.4 ft²
OA = 19.0 ft²
O A = 20.0 ft²
Answer:
Hello,

Jeff brown has collected sales data for his cupcake stand. calculate the moving average forecast for period 13 with n = 4. round your answers to 2 decimals.
The moving average forecast for period 13 = 44.55.
What is average forecasting?A statistical technique for predicting long-term trends is the moving average. The method entails shifting the range while averaging a group of numbers from a particular range.The equation is as follows: previous month's sales x velocity = additional sales; subsequent month's anticipated sales are equal to additional sales plus the prior month's rate.You take each of the three periods in our three-period spread and apply a percentage of that period's average to create a weighted average. To get a more precise projection, we might, for instance, pick 15% of period 1, 20% of period 2, and then 35% of period 3.Calculate the moving average forecast for period 13 with n = 4. round your answers to 2 decimals.
The moving average technique averages a number of the most recent actual values in the data given for generating the forecast. When n=4, a four-period moving average is calculated by taking the average of 4 most recent actual values. Here we have to take the average of actual sales values of periods 9,10, 11, and 12.
Hence moving average forecast for period 13= (A9+A10+A11+A12)/4
= (60+48+41.2+29.0)/4

. Two similar prisms have surface areas of 98 square centimeters and 18 square centimeters. What is the ratio of the height of the large prism to the height of the small prism?
The ratio between the height of the prisms is 7/3.
What are prisms?Prisms are geometric bodies or solids that start from the extrusion of a plane figure, and that is the origin of their name, for example, if the base is square, the prism is quadangular.
What is a numerical ratio?A numerical ratio is a constant value that relates a system of two or more variables, it allows us to know how their variations will be as the values change.
Since prisms are said to be similar, then the ratio of their areas and heights must be proportional, expressed as:
a²/b² = 98/18
a²/b² = 49/9
a/b = 7/3

The correct is option A which is definition of bisector
What is bisect?
The term bisect refers to dividing into two equal parts. In mathematics, the term is used mostly in geometry, when a line intersects another line, say line A intersects line B, when the point of intersection is the mid point of line A. Then it can be said that line B is the bisector of line A. If the point of intersection is also the mid point of line B then line A also is the bisector of line B. Bisector then refers to the line that bisects the other.
The terms bisect and bisector is not used for lines alone it can be used in many other circumstances for instance say angle. An angle may be bisected into two equal parts two. An example is angle 180 degrees can be bisected to get angle 90 degrees. Angle 90 degrees can be further bisected to give angle 45 degrees.
Hence we can say that line DF which is 96 is bisected by line EG to get two equal parts of 48 each, This means that line EG intersects line DF at the midpoint

A particle moves in a velocity field v(x, y) = x2, x y2 . if it is at position (x, y) = (4, 5) at time t = 6, estimate its location at time t = 6.01.
New location of a particle moves in a velocity field at time 6.01 is given by: (7.49, 2.11).
What is a velocity field?Think about the fluid flow's steady-state velocity vector field, or v. The instantaneous velocity of the fluid particles (atoms or molecules) as they pass through the point (x,y) is measured by the vector v(x,y).
The vector field used to quantitatively characterize the motion of a continuum in continuum mechanics is called the flow velocity in fluid dynamics, macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism. The flow speed is a scalar and is represented by the length of the flow velocity vector.
It is also known as a velocity field, and a velocity profile is what it is known as when it is measured along a line.
Everything about a fluid's motion is efficiently described by its flow velocity.

The slope of the line with points (-1/2 ,-1/2) and (-3,-4) is 1.4
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that slope, slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
For the pairs of points (-1/2 ,-1/2) and (-3,-4)
⇒ m = [tex]\frac{-4- (-1/2)}{-3 - (-1/2)}[/tex]
