Which statement best describes the difference of the mean of the two data sets?
A.
It is equal to about 0.5 times the mean absolute deviation of either data set.
B.
It is equal to about 1 times the mean absolute deviation of either data set.
C.
It is equal to about 1.5 times the mean absolute deviation of either data set.
D.
It is equal to about 2 times the mean absolute deviation of either data set.
Answer:
B.) It is equal to about 1 times the mean absolute deviation of either data set.
Explanation:
Given the scores :
Williams :
89,97, 78, 81, 91
Andre :
90, 74, 73, 87, 82
The mean scores :
Mean = ΣX / n
William's mean score = 436 / 5 = 87.2
Mean absolute deviation :
[|89-87.2| + |97-87.2| + |78-87.2| +|81-87.2| + |91-87.2|] / 5
William's mean absolute deviation = 6.16
Andre's mean score = 406 / 5 = 81.2
Andre's mean absolute deviation =
[|90-81.2| + |74-81.2| + |73-81.2| +|87-81.2| + |82-81.2|] / 5 = 6.16
Difference of the mean = 87.2 - 81.2 = 6
Mean absolute deviation of each dataset = 6.16
The closest relationship between the mean difference and the mean absolute deviation is :
Mean difference is about 1 times the mean absolute deviation

Geomagnetic reversals __________. Group of answer choices Provide strong evidence for sea floor spreading Reveal that polar wandering may have occurred. Were discovered by the Deep Sea Drilling Project Confirmed the existence of subduction zones Cause the movement of plates
Answer:
The answer is "Provide strong evidence for seafloor spreading".
Explanation:
The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.
A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.
In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.

¿Qué pasaría si los fenómenos naturales, como las lluvias, por ejemplo, se intensificaran o, por el contrario, dejaran de producirse?
Fenómenos naturales es a veces una tragedia, pero a veces para ayudar a nuestro planeta. Lluvia, nieve y granizo se encuentran entre algunos de ellos. Los tres fenómenos producen agua y puede ser grave, pero por eso siempre debemos ser prudentes. El calentamiento global está aumentando y está consumiendo el hábito natural de la Antártida. Esto también provoca poner en peligro a la criatura.
¡Espero haberte ayudado!
Si la lluvia se intensifica puede tener efectos positivos como el riego de zonas de cultivo, y efectos negativos como las crecientes de los ríos que desencadenan desastres naturales. También su ausencia puede causar efectos negativos como escasez de agua.
Fenómeno natural es un concepto que se refiere a distintas manifestaciones de la naturaleza que se caracterizan por no ser provocadas por acción humana tales como:
HuracánLluviaRadiación Solar.Formación de montañas.Erupción de un volcán.El viento.Los truenos.Sismos y terremotos.Los fenómenos naturales pueden tener efectos negativos, positivos y neutros sobre las comunidades humanas. Por lo anterior, si las lluvias se intensifican podrían causar efectos positivos como riego de zonas de cultivo. No obstante, también puede tener efectos negativos como crecientes de ríos que desencadenen desastres naturales.
Por otra parte, la ausencia de lluvia puede causar efectos negativos dado que limitaría el acceso al recurso del agua, lo que podría afectar la vida vegetal y animal.

d. This statement is clearly false. The HST observes visible and infrared light, not gravitational waves.
Answer: This statement is clearly false. The HST observes visible and infrared light, not gravitational waves.
Explanation:
Gravitational waves refers to ripples in spacetime. The statement that gravitational waves are best observed with the Hubble Space Telescope is false.
This is because the Hubble Space Telescope is used in observing visible and infrared light, not gravitational waves. The telescope has helped scientists to understand how the planets are formed.
If an earthquake measures 1.5 on the Richter Scale, what is the intensity of this earthquake, relative to a 0-level earthquake? Round off your answer to the nearest integer.
Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale. This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)The recovery of bald eagle populations was a slow process. One reason for this was because they are a K-selected species.

The map shows the locations of 13 major river basins in Africa: the Senegal, Volta, Niger, Lake Chad, Nile, Lake Turkana, Juba Shibeli, Ogooue, Congo, Zambezi, Okavango, Limpopo and Orange river basins. This spectacular Southern African waterfall, considered to be among the greatest in the world, is located along the Zambezi River and straddles the border between Zambia and Zimbabwe. The awe-inspiring nature of the waterfall is in part due to its enormous width—more than 5,500 feet (1,700 meters). The waters plunge as far as some 355 feet (108 meters) down and drop not into an open basin but into a dramatic-looking chasm. Victoria Falls is known for its veil of mist visible from miles away; the name given to the falls by an indigenous group is Mosi-oa-Tunya (“The Smoke That Thunders”). Victoria Falls and the adjoining areas were collectively designated a World Heritage site in 1989.

if 73.87% of South Africa's households use electricity for cooking. what do the remaining 26% use? suggest other three resources
Answer:
Africa’s population is among the fastest growing and youngest in the world. One-in-two people added to the world population between today and 2040 are set to be African, and the continent becomes the world’s most populous region by 2023, overtaking China and India.
More than half a billion people are added to Africa’s urban population by 2040, much higher than the growth seen in China’s urban population in the two decades of China’s economic and energy boom. How Africa meets its growing energy needs is crucial for the continent’s economic and energy future, as well as for global trends.
Growing urban populations mean rapid growth in energy demand for industrial production, cooling and mobility. With the growing appetite for modern and efficient energy sources, Africa also emerges as a major force in global oil and gas markets. The projected growth in oil demand is higher than that of China and second only to that of India as the size of the car fleet more than doubles (the bulk of which have low fuel efficiency) and liquefied petroleum gas (LPG) is increasingly used for clean cooking. Africa’s growing weight is also felt in natural gas markets as the continent becomes the third-largest source of global gas demand growth over the same period.
