The length of the strip of paper is 7 inches.

<h3>How to calculate the value?</h3>

From the information, Jada cuts a strip of paper into 5 equal parts and each part is 7/5 inches long.

Therefore, the length of the strip will be:

= 7/5 × 5

= 7 inches.

The length is 7 inches.

Una bacteria se divide en dos cada 6 minutos Si a las 12:15 horas se coloca una bacteria en un recipiente¿ A que hora habrá 128
DaniilM [7]

Answer:

A las 12:57 horas habrá 128 bacterias en el recipiente.

Step-by-step explanation:

Una función exponencial es aquella en que la variable independiente x aparece en el exponente y tiene de base una constante a. Su expresión es:

f(x)= aˣ

Siendo a un real positivo, a > 0, y diferente de 1.

Cuando 0 < a < 1, entonces la función exponencial es una función decreciente y cuando a > 1, es una función creciente.

Algunos tipos de bacterias se reproducen por "mitosis", dividiéndose la célula en dos cada espacios de tiempo pequeños, como sucede en este caso. Entonces, "a" tendrá un valor de 2, que es la cantidad en la que se divide la bacteria, y "x" será los intervalos de tiempo. Si hay 128 bacterias en el recipiente, la expresión exponencial del crecimiento de la bacteria en x intervalo de tiempo será:

2ˣ= 128

Una manera de resolver la x es aplicando logaritmos. Entonces, aplicando el logaritmo común de ambos lados. (Cuando la base no está escrita, se trata de la base 10):

log (2ˣ) = log (128)

Aplicando la propiedad de la potencia de los logaritmos:

x* log (2)= log (128)

x= log (128) ÷ log (2)

x= 7

Cada intervalo de tiempo tiene 6 minutos, que es el tiempo en que una bacteria se divide en 2. Entonces, el tiempo que se tarda en obtener 128 bacterias se calcula como:

7 intervalo* 6 minutos= 42 minutos

Si a las 12:15 horas se coloca una bacteria en un recipiente, entonces el horario a la que habrá 128 bacterias se calcula como:

12:15 + 42 minutos= 12:57

<u><em> A las 12:57 horas habrá 128 bacterias en el recipiente.</em></u>

Answer:

Slope=0

Y intercept: (0,3)

Step-by-step explanation:

B/c it's just a horizontal line, the slope is 0.

It touches the point (0,3) which is the y-intercept

A sample of 90 women is​ obtained, and their heights​ (in inches) and pulse rates​ (in beats per​ minute) are measured. The line
gayaneshka [121]

Answer:

the best predicted pulse rate of a woman who is 66 in tall = 79.78 beats per minute

Step-by-step explanation:

We are given that;

Regression line: y^ = 18.4 + 0.93x

Now we want to find out the best predicted pulse rate of a woman who is 66 in tall.

Thus;

If x = 66, then the predicted height is:y^ = 18.4 + 0.93(66)

y^ = 79.78 beats per minute
