The answer is -16b^4

-23b^4-7b^4= -30^4
And simplified it is -16b^4

Al precio de p dólares por unidad, se venden x unidades de cierto artículo al mes en el mercado con p=50-0.5x ¿Cuántas unidades

Ray Of Light [21]

Answer:

Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

Step-by-step explanation:

De acuerdo con el enunciado, $x$ es la cantidad mínima de artículos a un precio de $p$ . Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:

$x \cdot p = 1200$ (1)

$p = 50-0.5\cdot x$ (2)

Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:

$x\cdot (50-0.5\cdot x) = 1200$

$50\cdot x -0.5\cdot x^{2} = 1200$

$0.5\cdot x^{2}-50\cdot x +1200 = 0$ (3)

Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:

$x_{1} = 60$ , $x_{2} = 40$

De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

(-10,2) (-5,-1) find mid point

zmey [24]

The Mid - point of the line segment is at coordinates - M(- 7.5, 0.5)

We have two coordinate points - A(- 10, 2) and B(- 5, -1)

We have to find the midpoint of this line AB.

<h3>What is Mid - Point Theorem?</h3>

It states that a line with endpoint coordinates as - $(x_{1} ,y_{1} )$ and $(x_{2} ,y_{2} )$ has its mid - point at the coordinates -

$(x_{M} ,y_{M} ) =( \frac{x_{1} +x_{2} }{2} , \frac{(y_{1} +y_{2} )}{2} )$

According to question, we have -

First coordinate Point - $(x_{1} ,y_{1} )$ = (- 10, 2)

Second coordinate Point - $(x_{2} ,y_{2} )$ = (- 5, - 1)

Using the Mid - Point formula, we get -

$(x_{M} ,y_{M} ) =( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )$ =

$x_{M} = \frac{-10-5}{2} = \frac{-15}{2} = - 7.5\\\\y_{M} = \frac{2 - 1}{2} = \frac{1}{2} = 0.5$

Hence, the Mid - point of the line segment is at coordinates -

M(- 7.5, 0.5)

-2w(w+8) what is the answer

Julli [10]

-2w (w + 8)
Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
-2w (w + 8) = 0
The roots are then:
w1 = 0
w2 = -8
Assuming you only have to rewrite the expression, the answer is:
-2w ^ 2 -16w
Answer:
w1 = 0
w2 = -8
-2w ^ 2 -16w

About 20% of babies born with a certain ailment recover fully. a hospital is caring for sixsix babies born with this ailment. t

alisha [4.7K]

Answer :

Yes, the experiment is a binomial experiment because it satisfies all the four characteristics of the binomial experiment :

1. Fixed number of trials

2. Exactly two outcomes

3. Outcomes are independent of each other

4. Probability of all the outcomes remains constant from trial to trial.

Success in the given experiment is that the baby recovers fully.

Hospital is caring for 6 babies , n = 6

p = 0.20 ( Success )

q = 1 - 0.20 = 0.80 ( Not a success )

Value of random variable x is the number of babies which are recovering fully, x = 0, 1, 2, 3, 4, 5 or 6
