Teniendo en cuenta la definición de media, mediana y moda:
el promedio de las lecturas obtenidas es 3,42la tirada que más se repite es 2.el mayor valor intermedio de todas las lecturas es 3.La media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central cuyo valor se obtiene al dividir la suma de todos los números entre la cantidad de ellos. Entonces, en este caso, el promedio de las lecturas obtenidas se calcula como:
[tex]Promedio=\frac{5+1+3+3+6+2+6+4+5+2+1+2+5+3+2+6+1+4+4}{19}[/tex]
Resolviendo:
Promedio= 3,42
El promedio de las lecturas obtenidas es 3,42.
Por otro lado, la moda de un conjunto de números es el número que aparece más a menudo dentro del grupo de datos.
En este caso, podes observar que la cantidad de veces que aparece cada número es:
1: 3 veces2: 4 veces3: 3 veces4: 3 veces5: 3 veces6: 3 vecesDebido a que el 2 es el número con mayor cantidad de repeticiones, la tirada que más se repite es 2.
Por último, la mediana es valor que se encuentra en la mitad justa entre los valores máximo y mínimo de los datos con los que se está trabajando; es decir, que al ordenar los número de menor a mayor, éste se encuentra justamente en medio de los valores.
En este caso, ordenando de menor a mayor las lecturas del dado:
1,1,1,2,2,2,2,3,3,3,4,4,4,5,5,5,6,6,6
se observa que el valor el mayor valor intermedio de todas las lecturas es 3.

It takes 1.5 seconds to reach the ground. What is its velocity when it reaches the ground?
Answer:
-14.8 m/s
Explanation:
Unless this is a trick question the initial velocity is 14.8 m/s. Velocity is a vector quantity, i.e. it has a magnitude AND direction. Speed which is a scalar is certainly 14.8 m/s. The direction of the vector depends on the axis of co-ordinates chosen; consequently velocity might be said to be - 14.8 m/s

I'm completely stumped as to how to do this.
I know the components of f1 are f1x= 1600, f1y=0, f2x= 433 f2y=250 and f3x= 467
Explanation:
You have already determined the components of the known forces so I won't repeat your work here. Since the resultant force [tex]\vec{\textbf{R}}[/tex] and F1 are completely along the x-axis, we can conclude that
[tex]F_{2y} = F_{3y} \Rightarrow F_{3y} = F_3\cos{\theta} = 250\:\text{lb}[/tex]
We can now solve for the magnitude of [tex]F_3:[/tex]
[tex]F_3 = \sqrt{F_{3x}^2 + F_{3y}^2} = \sqrt{(467)^2 + (250)^2}[/tex]
[tex]\:\:\:\:=529.7\:\text{lb}[/tex]
The angle [tex]\theta[/tex] is then
[tex]\tan{\theta} = \dfrac{F_{3y}}{F_{3x}} = \dfrac{250}{467}[/tex]
or
[tex]\theta = 49.2°[/tex]
A small piece of aluminum (atomic number 13) contains 10^15 atoms (The atomic number is the number of protons; it determines the (positive) electric charge of the nucleus and, thus, the number of electrons in a neutral atom.) If the piece of aluminum has a net positive charge of 3.0 uc what fraction of the electrons that the aluminum had when it was neutral would have had to be lost?
Answer:
3 micro coulombs = 3 * 10E-6 coulombs charge of aluminum
13 * 10E15 * 1.6 * 10E-19 = 2.08 E-3 Coulombs - charge of atoms in Al
3 * 10E-6 / 2.08 * E-3 = 1.44 * E-3 = .00144 = .144 %
.00144 of the original electrons would have to be lost
A light bulb uses 40.0 W of power when connected to a 110 V (DC) outlet. If the same bulb is connected to a European 220 V outlet, how much power will the bulb use?
If the bulb's resistance doesn't change, the power it uses is proportional to the square of the voltage. So doubling the voltage quadruples the power.
On 220 V, the bulb uses (4 • 40w)= 160 W.
It glows very brightly.
For a very short time.
Because it also gets very hot, and burns out.
After a few seconds, it uses zero watts.

Define limitations in an experiment
Answer:
The limitations of the experiment are those characteristics of design or methodology that impacted or influenced the application or interpretation of the results of your study.
Bradd stands 6km west of a flagpole, and runs towards it with a speed of 9km/h. Pitt stands 5km east of the flagpole, and runs towards it with a speed of 8km/h. At what displacement from the flagpole are they when they meet?
Answer:
176 m west of the flagpole.
Explanation:
In exact and precise interpretation of the question the answer is 0 m as they would both crash into the pole when they got there and presumably stop having suffered broken noses and serious groin injuries.
However my GUESS as to the intent of the question is that the first to reach it will sidestep the flagpole slightly and continue on their current path until they meet and slap a high five as they pass one another.
In that case, they have 6 + 5 = 11 km to traverse at a closing rate of 9 + 8 = 17 km/hr.
They will meet in 11 km / 17 km/hr = 0.647 hrs
Bradd will have covered 9 km/hr(0.647 hr) = 5.823 km
meaning that they will be 6 - 5.823 = 0.176 km or 176 m west of the flagpole.
Pitt will have covered 8 km/hr(0.647 hr) = 5.176 km
meaning they will be 5 - 5.176 = - 0.176 km east which equals 0.176 km west of the flagpole
What is the amount of force exerted by gas particles?
Answer:
Pressure is the force divided by the area on which the force is exerted, and temperature is measured with a thermometer. We gain a better understanding of pressure and temperature from the kinetic theory of gases, which assumes that atoms and molecules are in continuous random motion.
A ball rolls down the street 9 meters in 3.5 seconds, what is it's average speed?
How do we find the Average Speed ?
The Average Speed is the distance traveled for the object, divided by the elapsed time taken to travel that distance, so the formula is :
S = D / T
where S = Average Speed, D = Distance, and T = Times
Here the object is the ball, the distance is 9 meters and the time elapsed for the ball to roll down the street is 3.5 seconds. Applying the formula we get :
S = 9 / 3.5 ≈ 2.6 metres per second
The ≈ symbols (which is the wavy equal sign) means we can't write the exact result, because there is an infinite quantity of numbers after the decimal point. So we need to give an approximation, since the result is 2.57142857142857...etc. we choosed to round up the result to 2.6.
Why is evolution called a scientific theory?
Answer:
Explanation:
Evolution is both a fact and a theory. Evolution is widely observable in laboratory and natural populations as they change over time. The fact that we need annual flu vaccines is one example of observable evolution. At the same time, evolutionary theory explains more than observations, as the succession on the fossil record. Hence, evolution is also the scientific theory that embodies biology, including all organisms and their characteristics. In this paper, we emphasize why evolution is the most important theory in biology. Evolution explains every biological detail, similar to how history explains many aspects of a current political situation. Only evolution explains the patterns observed in the fossil record. Examples include the succession in the fossil record; we cannot find the easily fossilized mammals before 300 million years ago; after the extinction of the dinosaurs, the fossil record indicates that mammals and birds radiated throughout the planet. Additionally, the fact that we are able to construct fairly consistent phylogenetic trees using distinct genetic markers in the genome is only explained by evolutionary theory. Finally, we show that the processes that drive evolution, both on short and long time scales, are observable facts.
The evolutionary theory is a scientific theory because its assumptions are well sustained by scientific data.
Scientific data refers to the body of knowledge obtained by using the scientific method.A scientific theory is a well-sustained explanation of one or more questions of the natural world, which was repeatedly tested and verified by using the scientific method.The theory of evolution by natural selection is a theory because it has been repeatedly corroborated through the scientific method.In conclusion, the evolutionary theory is a scientific theory because its assumptions are well sustained by scientific data.

Which of the following is NOT an important phenomenon that commonly erodes and weathers exposed rock outcrops to form sedimentary material?
a) Lightning
b) Wind
c) Rain
d) Freezing/Thawing
Answer:
Explanation:
While each of these can cause erosion and weathering, lightning is probably the least important as it occurs less frequently and affects a much smaller surface area when it strikes.
Wind is not very effective by itself, but it can carry abrasives which work to degrade rock surfaces. It covers a very large area at once so the net effect can be moderate to large especially desert areas where plants are not readily available to disrupt the flow.
Rain covers huge areas and is quite common.
Freezing/Thawing cycles cover large areas and are quite common in the temperate and arctic latitudes and even in tropical altitudes.
Attached is a photo taken atop Half Dome in Yosemite National Park showing two of thousands of divots in the rock there caused by lightning strikes. The current in the lightning heats the stone causing water trapped in it to flash to steam. The increased pressure inside the stone can overwhelm the material strength and blow rock chunks over a fairly good sized area. This is a fairly rapid weathering and erosion when it occurs, but that is typically limited to a few dozen days per year and occurs mostly on high ground where lightning is more likely to strike earth.
