Answer:

$E=m.c^2\\m=\frac{E}{c^2}$

Step-by-step explanation:

If we have the values of E (energy) and c (speed of light) to obtain an equation that gives us the value of m (mass of the object), we clear the variable m from the initial equation

$E=m.c^2\\m=\frac{E}{c^2}$

Select the number line that shows the decimal for the following fraction. sixth tenths

Komok [63]

Answer:

Step-by-step explanation:

to figure this out, lets understand how decimals work

a decimal number in the tens place before the decimal

↓ here

0.00

that number will be the same number as the numerator or top number of a fraction in tenths

↓ here

0/10

so say it was 4/10 we needed to find, we would look on the number line for 0.40 like in answer choice B (NOT THE CORRECT ANSWER FOR THIS PROBLEM)

hope this helps you out on your work :)

Identify the level of measurement of the data, and explain what is wrong with the given calculation. In a survey, the hair col

belka [17]

Answer:

This type of data are not measurement of anything , so it is not feasible to calculate their average(Mean)

Step-by-step explanation:T

The data are at the level of measurement that are Nominal

In level of nominal measurement, letters, numeric and alpha-numeric, words, symbols are used to classify data in the example stated.

Now we recall that,

Brown hair = 100,

Blond hair = 200,

Black hair = 300

Anything else = 400

Thus, 100, 200, 300, 400 are used as code numbers for hair colors and does not have any importance to their values numerically.

There is no arithmetic solutions such as average, total which cannot be solved using these numbers.

Therefore the average mean calculated is not feasible

Samuel, Martín y Santiago salen a montar bicicleta de Cali hacia Palmira. La distancia entre Cali y Palmira es de 29.3 KM. En la

myrzilka [38]

Answer:

a) Martín recorrió más distancia, b) A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente, c) La distancia recorrida promedio es 21.889 kilómetros, d) Martín recorrió 0.333 kilómetros más que Santiago.

Step-by-step explanation:

a) En primer lugar, convertimos la distancia recorrida por cada persona a su forma decimal:

Samuel

$\frac{178}{8}\,km = 22.25\,km$

Martin

$21\,km + \frac{3}{4}\,km = 21.75\,km$

Santiago

$21\,km + \frac{5}{12}\,km = 21.417\,km$

Como puede apreciarse, Martín recorrió más distancia.

b) La distancia faltante es igual a la sustracción de la distancia recorrida por la persona a la distancia total:

Samuel

$x = 29.3\,km -22.25\,km$

$x = 7.05\,km$

Martin

$x = 29.3\,km - 21.75\,km$

$x = 7.55\,cm$

Santiago

$x = 29.3\,km - 21.417\,km$

$x = 7.883\,km$

A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente.

c) La distancia recorrida promedio se obtiene sumando las distancias recorridas de las tres personas y dividiendo el resultado por la cantidad de personas:

$\bar{x} = \frac{22.5\,km + 21.75\,km + 21.417\,km}{3}$

$\bar x = 21.889\,km$

La distancia recorrida promedio es 21.889 kilómetros.

d) Esta diferencia se encuentra a restar la distancia recorrida por Santiago a la distancia recorrida por Martín:

$x = 21.75\,km - 21.417\,km$

$x = 0.333\,km$

Martín recorrió 0.333 kilómetros más que Santiago.
