The function ggg models the number of mosquitoes (in millions of mosquitoes) in a certain area as a function of rainfall (in centimeters) in that area.
Answer:
6cm produces the largest mosquito
Step-by-step explanation:
The question has missing details.
From the complete question, the function is:
[tex]g(x) = 12x-x^2[/tex]
Required
Which area of rainfall produces the most mosquito
This implies that, we calculate the maximum of the function.
This is calculated as:
[tex]Max = -\frac{b}{2a}[/tex]
We have:
[tex]g(x) = 12x-x^2[/tex]
Rewrite as:
[tex]g(x) = -x^2 + 12x + 0[/tex]
From the above:
[tex]a= -1[/tex]
[tex]b = 12[/tex]
[tex]c = 0[/tex]
So, we have:
[tex]Max = -\frac{b}{2a}[/tex]
[tex]Max = -\frac{12}{2 * -1}[/tex]
[tex]Max = \frac{12}{2}[/tex]
[tex]Max = 6[/tex]
This implies that:
[tex]x = 6[/tex] ---- the maximum
When rainfall is at 6cm, there is a maximum number of mosquitoes
The maximum is then calculated as:
[tex]g(x) = 12x-x^2[/tex]
[tex]g(6) = 12 * 6 - 6^2[/tex]
[tex]g(6) = 72 - 36[/tex]
[tex]g(6) = 36[/tex]
The maximum number of mosquito is 36 million

A robot vacuum advertises that it can clean a 120-square-foot room in 1/2 an hour. How many square feet could the robot vacuum clean in 1 hour?
Answer: 240 square foot room
Step-by-step explanation: They ask for how many square feet in 1 hour which is double the 1/2 hour. So, just do 120x2=240 to get your answer! (Don’t forget to label ,square-feet,)

1.) Finding the top volume mean multiplying the height of the top (6 m) , width, and length.
2.) Finding the bottom is the height of the bottom (5 m) , width, and length.
3.) Finding the total is adding both bottom and top!

triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?
19.4 inches
Step-by-step explanation:
Area of the traingle = 230.86 sq. inches
Height of the triangle = 23.8 sq. inches
We have,
Area of the triangle = 1/2bh
where,
b = base of the traingle
h = height of the triangle
Now, substituting the given info we get,
230.86 = 1/2b (23.8)
230.86 × 2/23.8 = b
b = 19.4
So, the base of the triangle is 19.4 inches

Sorry I suck at taking pictures, and math apparently.
Answer:Bueno, normalmente en los artículos semanales intento transmitir dudas o cuestiones que están en el campo, los trending topics del sector porcino, y está claro que la estadística no es uno de ellos, pero precisamente ayer se dio una situación que me llevó a escribir ésta entrada.
Todos los que trabajamos en el sector porcino estamos acostumbrados a manejar y calcular un montón de datos que nos proporciona el programa de gestión, y en muchas ocasiones realizamos pequeñas (o grandes) pruebas, donde manejamos infinidad de números (pesos, GMD, IC etc…)
Lo que sí es cierto, es que la mayoría de nosotros usamos siempre la media como herramienta fundamental. Media de Nacidos vivos, Media de destetados, Media de peso al nacer, media de peso al destete…..media, media, media…y ¿qué tal si usáramos la Mediana?
Éste fue el debate que tuve ayer con un ingeniero agrónomo (si, si, y yo Veterinaria, diversión asegurada), y el que me ha inspirados para hoy.
Para el que, en estos momentos, esté rebuscando en los archivos de su cerebro, “yo esto lo sabía”, un pequeño recordatorio:
La media o promedio, Se interpreta como “punto de equilibrio” o “centro de masas del conjunto de datos. Es un cálculo muy sencillo en el que intervienen todos los datos. Consiste en el sumatorio de todos los datos dividido por el número de valoresLa mediana, en cambio, es un valor de la variable que deja por debajo de sí a la mitad de los datos, y por encima, la otra mitad.( una vez que estos están ordenados de menor a mayor). Se sitúa, por lo tanto, en la mitad real de los datos.
Es mucho más difícil de calcular:
Con un ejemplo se entiende muchísimo mejor.
Imaginaos una empresa en la que la mayoría de los trabajadores tienen un sueldo de 1000 euros, excepto 2 encargados que cobran 2000 y el jefe que cobra 6000 euros mensuales.
¿Cuál es el salario medio de la empresa?
Si vemos la media sale casi 2000 euros, si miramos la mediana, nos da 1000.
¿Cuál se aproxima más a la realidad?
Cuando los datos son muy homogéneos la media nos da un valor representativo de la realidad, pero cuando los datos son muy heterogéneos no.
Un ejemplo más cercano a nosotros
Queremos saber el peso de los lechones a destete. Imaginemos que la camada A tiene los siguientes pesos: (4-3-5-4.5-6.1-5-3-5.1-6.4-6-6.5-5.5-4.9).

Find the greatest common factor of 4c3 and 6m2.
Answer:
The GCF is 2
Step-by-step explanation:
Here, we want to find the greatest common factors of the two terms
We have the terms written in terms of the products of their multiples as follows;
4c^3 = 2 * 2 * c * c* c
6m^2 = 2 * 3 * m * m
As we can see, the greatest common factor of the two is simple the value 2

What is the volume of the rectangular prism?
9514 1404 393
Answer:
17 7/9 yd³
Step-by-step explanation:
The volume is the product of the dimensions.
V = LWH
V = (3 1/3 yd)(2 2/3 yd)(2 yd) = (10/3)(8/3)(2) yd³ = 160/9 yd³ = 17 7/9 yd³
__
Additional comment
You can guess the correct answer with a couple of estimates.
volume is greater than (3)(2)(2) = 12 . . . . rounding down to integer
volume is less than (3 1/3)(3)(2) = 20 . . . . rounding 2 2/3 up to 3
Based on the way these numbers are rounded, the volume is closer to 20 than to 12. This strongly suggests that 17 7/9 is the correct answer.

The line plot shows the weights of pumpkins available at a farm stand. The pumpkins cost $0.30 per pound. A line plot named "Pumpkin Weights" shows data from 6 to 14 pounds in intervals of 1 pound. 6 has 3 dots. 8 has 5 dots. 9 has 1 dot. 10 has 7 dots. 12 has 4 dots. 13 has 2 dots. 14 has 1 dot. A baker purchases all of the pumpkins to make pies. If she uses a $100 bill to pay for the pumpkins, how much change will she receive? Enter your answer in the box. $
Answer:
The answer is 32.5
Step-by-step explanation:
First start with (6x3) + ( 8 x 5 ) + ( 9 x 1 ) + ( 10 x 7 ) + ( 12 x 4 ) + ( 13 x 2 ) + ( 14 x 1 ). This equals 225 pounds for all of the pumpkins. The baker buys all of them so multiply 225 by 0.30 since each pound costs 0.30. 225 x 0.30 = 67.5 and the baker pays a 100 dollars so 100 - 67.5 = 32.5. The answer is 32.5.
P.S: I has this same question and 32.5 was correct. PLZ give me Brainliest. Thank you!

The Area of a rectangular garden can be represented by the expression 15x 2 - 7x - 2. The length of the garden can be represented by 5x + 1. Write an expression that represents the perimeter of the garden.
Answer:
16x-2
Step-by-step explanation
Area of the garden = length × width
Substitute the given value
15x 2 - 7x - 2. = 5x+1 × width
Factorize the area
15x^2 - 7x - 2.
15x²-10x+3x -2 =0
5x(3x-2)+1(3x-2)
5x+1(3x-2)
Hence other side so be 3x-2
Perimeter = 2(L+W)
P = 2(5x+1+3x-2)
P = 2(8x-1)
P = 16x-2
Hence the expression that represents the Perimeter is 16x-2
