What are mathematics operations?An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations. A zero-arity operation, also known as a nullary operation, is a constant. The mixed product is an example of an arity 3 operation, also known as a ternary operation.
So,

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,
answer C: 19.0ft (rounded to 1 digit)
Step-by-step explanation:
[tex]s=\dfrac{6+7+11}{2} =12\\\\A=\sqrt{12*6*5*1} =\sqrt{360}= 18,97366596...\approx{19.0}\ (ft^2)[/tex]
Answer:
19.0 ft^2.
Step-by-step explanation:
s = (6 + 7 + 11)/2
= 12
--> A = √[12(12-6)(12-7)(12-11)]
= √(12 * 6 * 5 * 1)

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
= 44.55

Explain why the sum of the probabilities of two mutually exclusive events is not always 1 .
The probabilities of mutually exclusive events are always smaller than 1.
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.The probability of events that are mutually exclusive cannot ever be added up to greater than one.
Unless the same set of occurrences is also exhaustive, in which case the total of their probabilities is exactly 1, the probabilities of mutually exclusive events are always smaller than 1.
The likelihood that none of these occurrences, which are mutually exclusive, will occur is (1 - the sum of their probabilities).

How is finding a missing term of a geometric sequence using the geometric mean similar to finding a missing term of an arithmetic sequence using the arithmetic mean? How is it different?
The two are similar, because: in both AP and GP, we can find the mean value using first and last values.
The two are different because: in both AP and GP, different methods are used to find the mean value.
What is an arithmetic and a geometric progression?A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.Now,
AP and GP are similar because the middle value, or mean value in both AP and GP, can be determined by using the initial and last values. They differ because there are various methods for calculating that number, and each phrase is distinguished by either a common ratio or a common difference.To learn more about arithmetic and geometric progressions, refer to the link: https://brainly.com/question/13899779

Are parallel lines (parallelism) and collinear points (collinearity) preserved under all transformations? Explain.
Yes, all transformations such as translations, reflections, dilations, and rotations preserve parallel lines (parallelism) as well as collinear points (collinearity).
Parallel lines:
Parallel lines are coplanar straight lines that don't intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.Collinear points:
The collinearity of a series of points in geometry is the property of their being on a single line.A set of points with this property is known as a collinear set. In a broader sense, the term has been applied to aligned objects, that is, things that are "in a line" or "in a row."So,
Translation, reflection, dilation, and rotation are all examples of transformation. In all of the preceding cases, parallel lines or collinear points will remain parallel or collinear.Therefore, yes, all transformations such as translations, reflections, dilations, and rotations preserve parallel lines (parallelism) as well as collinear points (collinearity).

¿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:

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 circular pillar candle is 2.8 inches wide and 6 inches tall. What are the lateral area and surface area of the candle? Round to the nearest tenth if necessary.
Lateral area and surface area of candle is 52.8 inches² and 65.1 inches².
We are given the height and width of pillar candle. So, firstly writing the formula of lateral area and surface area of cylinder followed by calculation.
Lateral area of cylinder = 2πrh, where r stands for radius and h represents height.
Surface area of cylinder = 2πrh + 2πr²
Radius = diameter÷2
Radius = 2.8÷2
Radius = 1.4 inches
Keep the values in formula for calculation -
Lateral area of cylinder = 2×3.14×1.4×6
Lateral area of cylinder = 52.78 inches²
Surface area of cylinder = 2×3.14×1.4×6 + 2×3.14×1.4²
Surface area of cylinder = 65.09 inches²
Rounding off to nearest tenth-
Lateral area of cylinder = 52.8 inches²
Surface area of cylinder = 65.1 inches²
Hence, the lateral area and surface area of cylinder is 52.8 inches² and 65.1 inches².
