-2(4g-3)=30

Multiply the bracket by -2

(-2)(4g)=-8g

(-2)(-3)=6

-8g+6=30

Move +6 to the other side. Sign changes from +6 to -6.

-8g+6-6=30-6

-8g=30-6

-8g=24

Divide both sides by -8

-8g/-8=24/-8

Cross out 8 and 8, divide by 8 and then becomes 1*1*g=g

g=24/-8

Answer: g=-3

Answer:

g =  - 3

Step-by-step explanation:

- 2(4g - 3) = 30

- 8g + 6 = 30

- 8g + 6 - 6 = 30 - 6

- 8g = 24

\frac{ - 8g}{ - 8}  =  \frac{24}{ - 8}

g =  - 3

A Regional College uses the SAT to admit students to the school. The university notices that a lot of students apply even though
Aliun [14]

Answer:

0.191 is the probability that a group of 12 randomly selected applicants would have a mean SAT score that is greater than 525 but below the current admission standard of 584.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 100

n = 12

We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(greater than 525 but 584)

Standard error due to sampling =

\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{100}{\sqrt{12}}

P(525 < x < 584) = P(\displaystyle\frac{525 - 500}{\frac{100}{\sqrt{12}}} < z < \displaystyle\frac{584-500}{\frac{100}{\sqrt{12}}}) = P(0.866 < z < 2.909)\\\\= P(z \leq 2.909) - P(z < 0.866)\\= 0.998 - 0.807 = 0.191 = 19.1\%

P(525 < x < 584) = 19.1\%

0.191 is the probability that a group of 12 randomly selected applicants would have a mean SAT score that is greater than 525 but below the current admission standard of 584.

Manuel y Carlos encuentran un libro de matemática usado y en una de las hojas se observa la figura de un poliedro demasiado borr
Sergio039 [100]

Answer:

Carlos tiene razón. El poliedro es un cubo.

Step-by-step explanation:

Comencemos analizando el número de caras del dodecaedro y del cubo.

El dodecaedro está conformado por 12 caras.

El cubo en cambio, está conformado por 6 caras.

En cuanto a aristas el dodecaedro tiene 30 aristas y en cambio el cubo tiene 12. Por ende, descartamos la idea de que el poliedro sea un dodecaedro.

Finalmente en cuanto a vértices, el dodecaedro tiene 20 vértices y el cubo tiene 8 vértices.

Si sumamos el número de caras y el número de vértices en el cubo obtenemos :

6 + 8 = 14

Con esto, verificamos que la figura borrosa es de un cubo y que Carlos tiene razón.
