Answer:
A. Standard deviation is always a non-negative number.
Explanation:
The true statement about standard deviation is that, standard deviation is always a non-negative number.
A standard deviation is calculated by taking the square root of variance and as such the value of standard deviation is always a positive number and not a negative number.
Additionally, the variance of a sample population is calculated by the summation of all the squared distances obtained from the mean divided by the total number of samples. Hence, all the values of the variance are always positive (non-negative) numbers because they are squared. Consequently, the standard deviation would as well always be a non-negative number.
The SD or the standard deviation is the measure of the amount of variation of the set of values. A low SD is close to the mean and a high SD indicates the values that are spread over a large region.
The SD has the same units as the variable. While the correlation coefficient is unitless. The SD is placed at an average distance from the mean value of all the variables. If the standard deviation is in hours then the SD will be measured separately. Hence the option E is correct.Learn more about the statements about standard deviation is true.

Read this excerpt from The Riddle of the Rosetta Stone by James Cross Giblin.
Between the time Champollion's books appeared and the end of the nineteenth century, thousands of rolls of papyrus and copies of temple and tomb inscriptions were brought to Europe and America. There scholars, using the deciphering methods Champollion had pioneered, traced the entire history of writing in Egypt. They discovered it had begun about 3100 B.C. when images of important people were first accompanied by hieroglyphs of their names or titles.

The types of percentage.In Mathematics, there are two main types of percentage and these include the following:
Percentage decreasePercentage increaseMathematically, percentage increase can be calculated by using this formula:
Percentage increase = [Final value - Initial value]/Initial value × 100
Substituting the given parameters into the formula, we have;
Percentage increase = [48 - 12]/12 × 100
Percentage increase = [36]/12 × 100
Percentage increase = 3 × 100
Percentage increase = 300%.

Dwight was told by his mystic guru that a special medicine would help him gain superhuman strength to fight bears. The instructions say “Take 2 drops per 10 pounds of body weight per day, in 4 doses a day.” Dwight weighs 180 lbs. There are approximately 20 drops in 1 mL. How many liters of the medicine should Dwight buy to have a supply for the next 5 years?
Answer:
Explanation:
1 dose = 2 drops * 180 / 10 = 36 drops /dose
4 doses = 4 * 36 = 144 drops / day.
144 drops * 365 = 52560 drops / year
52560 * 5 = 262800 drops / 5 years.
262800 / 20 = 13140 mL
13140 ml / 1000 = 13.140 L for a 5 year supply.
We are still not quite finished. There must be at least 1 leap year and maybe 2.
1 leap year would add 0.144 Liters
2 leap years would add 0.288 liters
I'm not sure how to finish the problem. I am going to say that we should ignore the leap years and stick with the answer. 13.140 L for 5 years.

Where do you see cultural diversity in your everyday life?
please write 50-100 words
Answer:
We could quite safely state that in our society everybody
deals on a daily basis with people from different origins
and cultures. In our neighborhoods, places of work
and study, and even in our families, there are people
who come from different continents, who speak
different languages, practice their own customs and
profess different religions.
At the same time, we share and interact in the same
environment which has many common values and norms,
and we all act similarly in everyday events –like going to
school or work, going for a walk, playing sports, shopping
at the supermarket or watching television–.
Cultural diversity contains great potential for
educational and personal development as it allows
for mutual enrichment, thanks to those factors
that differentiate us –languages, customs, historic
memories, beliefs, etc.–. This mutual enrichment is
often made possible due to those factors that unit us
–common values and norms of coexistence in everyday
situations–.
We live in a plural society where cultural diversity exists
and is manifest on many levels: the autochthonous
population is diverse and the immigrant population is
made up of many sociologically and culturally different
groups. Although common aspects are shared, there
is also diversity within these groups as no person is
exactly the same as another. This diversity is manifest
in many different cultural expressions which form part
of human heritage

Answer:
Thematic statement: The practice of sport is important for the development of the organism, but it must be balanced with the other activities that the individual must complete on a daily basis.
Rhetorical strategy that creates logos: If the sport is hampering academic development or physical condition it is not being beneficial.
Explanation:
In "The Proper Place for Sports" Roosevelt talks to his son about the importance of playing sports as a recreational activity that boosts health and well-being. However, he affirms that he feels concerned that the practice of sports will harm his son's academic performance and also that the sport that the child wants to do is too heavy for his physical conditioning. Rooselvelt says he allows his son to play sports if this is not harmful, that is, the sport must be beneficial and be in balance with his son's academic success and physical integrity.
The thematic statement is The value of sports lies in their ability to cultivate character and promote a well-rounded society. Rhetorical strategy creating logos is ancient civilizations. Effectiveness is providing historical context and data.
