Considerando la definición de una ecuación, la expresión que representa esta situación es x(x+5)= 100.

<h3>Definición de ecuación</h3>

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.

Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.

<h3>Expresión del área del jardín rectangular</h3>

En este caso, se sabe que el área del jardín rectangular es 100 m² y que uno de sus lados es de 5 m mayor que el otro. Esto puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa la medida de uno de los lados del jardín.

Por otro lado, el área de un rectángulo se calcula a partir de los dos lados diferentes (a y b). Es el producto de los dos lados contiguos del rectángulo, esto es, el producto entre el lado mayor por lado menor.

Entonces:

  • Lado del jardín rectangular: x
  • Lado 5 m mayor: x + 5
  • Área del jardín rectangular: 100 m²

Entonces, la ecuación queda expresada como:

x(x+5)= 100

En resumen, la expresión que representa esta situación es x(x+5)= 100.

A woman is randomly selected from the 18-24 age group. For women of this group, systolic blood pressures (in mm Hg) are normally
dybincka [34]

Answer:

0.0274

Step-by-step explanation:

The mean is \mu =114.8 and the standard deviation is \sigma =13.1.

Calculate

Z=\dfrac{X-\mu}{\sigma}

for X=140:

Z=\dfrac{140-114.8}{13.1}\approx 1.9237.

If X\sim N(114.8,\ 13.1), then Z\sim N(0,1)

and

Pr(X>140)=Pr(Z>1.9237).

Use table for normal distribution probabilities to get that

Pr(Z>1.9237)=1-Pr(Z\le 1.9237)=1-0.9726=0.0274.

A submarine starts at sea level and travels to a position that is a little lower than −24 feet. Use the drop-down menus to compl
Black_prince [1.1K]

Answer:

  1. The submarine's position means the distance it traveled is greater than 24 feet
  2. A possible position of the submarine is -27 feet

Step-by-step explanation:

Distance is generally a positive number. (Displacement, or position may be negative, as in this case.) If the sub started at 0 feet and went lower than -24 feet, it traveled a distance of more than 24 feet (greater than 24 ft).

Of the numbers listed, the only one lower than -24 is -27.
