So 72 pencils and 24 calculators
so greates number of identical calculators

this means
what is the biggest number that we can divide 72 and 24 by and get a whole number
this is called the GCM or greatest common multipule

to find the GCM, you factor 72 and group the like ones
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
so the common group is 2 times 2 times 2 times 3 or 24
so the greates number of packs is 24

so pencils
72 divided by 24=72/24=3
3 pencils per pack

24 divided by 24=24/24=1
1 calulator per pack


answer is 3 pencils and 1 calculator per pack

3  pencils per box.

The GFC of 72 and 24 is 24. 72 divide by 24 is 3, 24 divided by 24 is 1.

Therefore, there are 3 pencils and 1 calculator each box. To answer your question, 3  pencils per box.

Porqué el valor del coeficiente de la variable al cuadrado de una función cuadratica no puede ser cero?
Nady [450]

Answer:

Ver respuesta abajo

Step-by-step explanation:

Una ecuación cuadrática es una ecuación que tiene la siguiente forma:

ax² + bx + c = 0

Donde:

a, b y c: coeficientes numéricos que acompañan a la incógnita.

Ahora bien, una función cuadrática es basicamente la misma ecuación cuadrática pero representada graficamente en un plano cartesiano.

Para que una ecuación o función sea cuadrática es absolutamente necesario y obligatorio que su expresión en forma de ecuación tenga el elemento "ax²", pues el "cuadrado" que es el exponente 2 que eleva la incógnita es lo que le da la característica de ecuación o función cuadrática.

Si el coeficiente que acompaña al x², es decir, el valor de a es cero, automaticamente pierde la condición de ser una función o ecuación cuadrática pues dicho término se hace cero su valor. En otras palabras, si x es un número cualquiera y está representado como incógnita, ¿qué sucede cuando multiplicas cualquier número por cero?, en este caso, el resultado es igual a cero:

Ejemplo:

0x² = 0 * x² = 0.

Por tanto, si el término cuadrático se hace cero, ya pierde la condición de cuadraticidad, y su gráfico no sería de forma parabólica, solo quedaría los términos bx + c, pero eso ya pertenece a una ecuación lineal o función afín.

Espero esto te sirva.

In the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births
SSSSS [86.1K]

Answer:

Step-by-step explanation:

Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.

From the above we find that population proportion is 0.03 and observed sample proportion is 0.04

So option a) is wrong

b) Correct

c) correct

d) Wrong

e) wrong

f) wrong

g) incomplete sentence

h) wrong

What is the solution to –4(8 – 3x) ≥ 6x – 8?<br><br> x ≥ –<br> x ≤ –<br> x ≥ 4<br> x ≤ 4
ollegr [7]

Answer:

x ≥ 4

Step-by-step explanation:

–4(8 – 3x) ≥ 6x – 8

Distribute

-32 +12x ≥ 6x – 8

Subtract 6x from each side

-32 +12x-6x ≥ 6x-6x – 8

-32 +6x  ≥  – 8

Add 32 to each side

-32 +32 +6x≥ 32– 8

6x ≥ 24

Divide by 6

6x/6 ≥ 24/6

x ≥ 4
