Por qué crees que el valor de la media no aparece en la tabla y es un número decimal?

1 answer:

3 0

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.

<h3>¿Qué es la media?</h3>

En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.

Calcular la media:

Usando la formula anterior, calculemos la media:

16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7

El valor de la media es 18.7, al respecto se puede observar que:

Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.
Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.

Calculate the interest rate when the principal is $300 and interest earned is $40 after 3

stich3 [128]

Answer:

4.4%

Step-by-step explanation:

solution:

principal (p) = $300

time(t) = 3 years

interest (I ) =$40

rate (r) = ?

we know that,

I = (PTR)/100*

OR, 40 = (300 *3 * R)/100

or, 40 = (900R)/100

or, 40 = 9R

or, 40/9 = R

or, R = 4.4%

Rate(r) =4.4%

5x + 8y = 6p Subtract 5x from both sides
8y = 6p - 5x Divide both sides by 8
y = $\frac{6}{8}$ p - <span> $\frac{5}{8}$ x</span>

Papessa [141]

Answer:

A bicycle store installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The owner of the store estimates the number of properly installed tires per week using the process below.

In the first hour of work on Monday, 49 out of 50 tires were properly installed.

So, there were about 8(49) = 392 properly installed tires on Monday.

Considering 5 working days per week, 5(392) = 1,960 is the number of tires properly installed in one week.

Which best explains the validity of the results?

The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.

The results are likely invalid because the entire population during one week was not part of the sample.

<u>The results are likely valid because a large number of tires produced during the week were part of the sample. </u>

The results are likely valid because each tire sampled was part of the population of tires that week.
