Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).

Answers

Answer:

the median score would be between 510 and 520

Step-by-step explanation:

The computation of the median score is shown below

In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it

Here

P(X = median) = 0.5 = 50%

So the median score would be between 510 and 520

Hence, the same is to be considered

If a rectangle has the sides 5x-3 and 6x-4 what is the area and perimeter

Answers

Step-by-step explanation:

[tex]A = lw[/tex]

[tex]A=(5x-3)(6x-4)[/tex]

[tex]A=30x^2-20x-18x+12[/tex]

[tex]A=30^2-28x+12[/tex]

[tex]P=2(l + w)[/tex]

[tex]P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14[/tex]

Answer:

[tex]Perimeter = 22x - 14[/tex]

[tex]Area = 30 {x}^{2} - 38x + 12[/tex]

Step-by-step explanation:

Length of rectangle (l) = 5x - 3

Weidth of rectangle (w) = 6x - 4

Perimeter of the rectangle = [tex]2(l + w)[/tex]

[tex] = > 2(5x - 3 + 6x - 4)[/tex]

[tex] = > 2(11x - 7)[/tex]

[tex] = > 22x - 14[/tex]

Area of the rectangle = [tex]l \times w[/tex]

[tex] = > (5x - 3)(6x - 4)[/tex]

[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]

[tex] = > 30 {x}^{2} - 20x - 18x + 12[/tex]

[tex] = > 30 {x}^{2} - 38x + 12[/tex]

What is the value of x?

Answers

Answer:

a value

Step-by-step explanation:

Answer:

Simplifying

4x + -23 = 2x + 17

Reorder the terms:

-23 + 4x = 2x + 17

Reorder the terms:

-23 + 4x = 17 + 2x

Solving

-23 + 4x = 17 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-23 + 4x + -2x = 17 + 2x + -2x

Combine like terms: 4x + -2x = 2x

-23 + 2x = 17 + 2x + -2x

Combine like terms: 2x + -2x = 0

-23 + 2x = 17 + 0

-23 + 2x = 17

Add '23' to each side of the equation.

-23 + 23 + 2x = 17 + 23

Combine like terms: -23 + 23 = 0

0 + 2x = 17 + 23

2x = 17 + 23

Combine like terms: 17 + 23 = 40

2x = 40

Divide each side by '2'.

x = 20

Simplifying

x = 20

The population of a town is 20.000. It decreases at a rate of 9% per year. In about how many years will the population be fewer than 13,000?

Answers

4 years, just like what the other person said he is right. because 9% of population is 1800

It will take approximately four years for the population to be fewer than 13,000.

What is the rate?

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

The population of the town is 20.000. It decreases at a rate of 9% per year.

The population of the town decreases by 20,000 × 9% = 1,800 people per year.

To determine how many years it takes for the population to fall below 13,000, you can use the formula:

= (20,000 - 13,000) / 1,800

= 3.88 ≈ 4 years

So, it will take approximately 4 years for the population to be fewer than 13,000.

Pareja de Erasmus Leyendo los testimonios que aparecen en su reportaje Generacin Erasmus, cualquiera podra pensar que la experiencia es siempre positiva y el no va ms, la meta final en la vida de un universitario. Pues bien, yo no estoy de acuerdo. Ms all de que a m el Erasmus me costase que mi novia me dejase, con la consiguiente depresin, me parece una excusa para pasarse medio ao o un ao -segn la beca- de vacaciones en el extranjero. Mi novia estuvo seis meses en Suecia, y las veces que fui a visitarla, de lo que me di cuenta es de que s habr un porcentaje (quiz un 10%) de los estudiantes que aprovechan la experiencia para estudiar y aprender un idioma; pero la otra gran mayora, lo nico que hacen es ir de fiesta en fiesta, y poco ms. Se pasan unos meses lejos de sus casas, en unas vacaciones de lujo costeadas por sus papatos, sin dar ni golpe. Adems observ la tendencia de muchos becados a mirar por encima del hombro y despreciar a todo aquel que no se hubiese planteado vivir la experiencia Erasmus. Como si vivir en cas a de los padres, acabar la carrera y encontrar trabajo a los 22 aos fuese algo demasiado simple... Leyendo los testimonios, uno se da cuenta tambin de que la beca Erasmus tiene cosas positivas, sirviendo como estmulo para espabilar al universitario, para aprender un idioma, para descubrir nuevos amigos y el valor de la amistad. Pero creo que para eso no es imprescindible vivir esta experiencia.
