Answer:
Explanation:
About 5 employees have ages that are older than 54 years.
What is a box plot?
A box plot provides the summary of a data using the five number summary that is minimum, lower quartile, median, upper quartile and maximum.
From the diagram, the third quartile is 54 years. Hence 75% of the employees are between 35 to 57 years.
25% are older than 54 years, hence:
Employers older than 54 years = 25% of 23 employees = 5.75
About 5 employees have ages that are older than 54 years.
Lavoisier organized a list of the known
elements of his day as four categories.
Newlands was the first to organize the
elements and show that properties repeated in a periodic way. Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.
Answer:
1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
Explanation:
2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
Answer:
A research was interested in whether there was a difference in appearance management by
gender and the situation context. For example, on a romantic date, group date or out with
friends. Using the data provided determine whether there are statistically significant
differences in appearance management (measured in seconds) by gender and situational
context. Include all four hypothesis testing steps and α = .05 level of significance.
