In a television commercial, the manufacturer of a toothpaste claims that more than four out of five dentists recommend the ingredients in its product. To test that claim, a consumer-protection group randomly sampled 400 dentists and asked each dentist whether they would recommend the ingredients in the manufacturer's toothpaste. 334 of the 400 dentists responded that they would recommend the ingredients in the manufacturer's toothpaste. Can the consumer-protection group conclude that the manufacturer's claim is true
Answer:
Following are the responses to the given question:
Step-by-step explanation:
n = 400
x = amount of displaying the reacts which would allow the fixing in the producing toothpaste = 334
Its value is more than [tex]\frac{4}{5}[/tex] dentists suggest the ingredient of the product.
[tex]\to p > \frac{4}{5}\\\\\to p > 0.8\\\\[/tex]

You have 3 red marbles, 5 green, and 2 blue marbles. What is the probability of pulling a blue marble and then replacing the first marble and then grabbing a green marble?
(As a percent)
Answer:
I think it's [tex]\frac{7}{10}[/tex].
Why 7/10?
Well, the probability of pulling out a blue marble + pulling out a green marble is also written as [tex]\frac{2}{10} +\frac{5}{10}=\frac{7}{10}[/tex]

Mike went to a football game with his family. They bought 5 boxes of popcorn and 3 programs, and spent $41. Sean's family went to the same game, bought 3 boxes of popcorn and 2 programs, and spent $26. How much does each program cost at the game?
Answer:
$7
Step-by-step explanation:
Let the price of a box of popcorn = b and the price of a program = p
we can make 2 equations:
5b+3p = 41 and 3b+2p=26
We can use the subtraction method be able to eliminate one of the variables and isolate the other one - to do it I will equalize the 'b' in both equations by multiplying by 5 and 3 respectively
5(3b+2p=26)
-3(5b+3p = 41)
15b+10p=130
-(15b+9p=123)
p=7 (therefore the answer is 7$)

Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{2}{3}[/tex] , then
y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = 2 + c ⇒ c = - 4 - 2 = - 6
y = [tex]\frac{2}{3}[/tex] x - 6 ← in slope- intercept form
Multiply through by 3 to clear the fraction
3y = 2x - 18 ( subtract 2x from both sides )
- 2x + 3y = - 18 ( multiply through by - 1 )
2x - 3y = 18 ← in standard form → D

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).

A shop has a fridge in a sale.The shop gives an extra 10% off the sale price of the fridge. Oliver says,"Altogether this is a saving of 30%"Is he correct?
Answer:
He is incorrect
Step-by-step explanation:
Given
[tex]Price\ off = 10\%[/tex]
Required
Is the total savings, 30%
From the question, we understand that the price of is 10%.
Since there is no other deduction to the original price of the fridge, then the 10% represents the total savings.
Hence: 30% savings is incorrect.

the same amount of wages, y, by working the same number of hours, x, in one week?
O Yes, because the slopes of the equations are different so the system of equations will have one solution.
No, because the slopes of the equations are different so the system of equations will have no solutions.
O Yes, because the slopes of the equations are the same so the system of equations will have infinitely many solutions.
No, because the slopes of the equations are the same so the system of equations will have no solutions.
Answer:

They will make the same amount in week 25

Solve the inequality. Graph the solution. −8≤2/5(k−2) The solution is .
Answer:
Step-by-step explanation:
Multiply both sides by 5(k - 2)
-8*5(k - 2) ≤2 Combine -8 and 5
-40 (k - 2) ≤2 Remove the brackets
-40k + 80 ≤2 Subtract 80 from both sides
-40k ≤ -78 Here's the trick part. Pay attention. Divide by - 40
k ≥ - 78 /- 40
k ≥ 1.95
Did you see what happened? The ≤ operation turned into ≥ That always happens when dividing by a minus or multiplying by a minus or if you change the side where literal coefficient is.

Answer:
448.25(2dp)
Step-by-step explanation:
1. Find the are of the entire rectangle:
length x breadth = 38 x 28 = 1064mm^2
2. Find the area of one semicircle
([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2
3. Multiply the area by 2
307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]
4. Subtract the area of the 2 semicircles from the area rectangle
1064-615.75 = 448.25 (2dp)

which shows the solution in the inequality? -2x > 18
A. x >9
B. x<-9
C. x>-9
D.x<9
HELP PLEASE
Answer: x<-9
Step-by-step explanation:
-2x>18
-2x/(-2)<18/(-2)
x< -9
The value of the solution in the inequality is,
⇒ x < - 9
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
We have to given that;
The inequality is,
⇒ - 2x > 18
Now, We can simplify as;
⇒ - 2x > 18
⇒ - x > 18/2
⇒ - x > 9
⇒ x < - 9
Thus, The value of the solution in the inequality is,
⇒ x < - 9
