Answer:
x = 35
h = 2.89
Solve for x first:
H (2x + 2) = 8 (x – 9)
Distributive Property:
2x + 2 = 8 (x – 9)
2x + 2 = (8 × x) (8 × –9)
2x + 2 = 8x – 72
Subtract 2 from both sides:
2x + 2 – 2 = 8x – 72 – 2
2x = 8x – 70
Combine like terms:
2x – 8x = 8x – 8x – 70
–2x = –70
Divide:
–2x/–2 = –70/–2
x = 35
Check work by plugging 35 back into equation:
2x + 2 = 8 (x – 9)
2 (35) + 2 = 8 (35 – 9)
70 + 2 = 280 – 72
H × 72 = 208
Solve for h:
H (2x + 2) = 8 (x – 9)
H (70 + 2) = 8 (35 – 9)
2.89 × 72 = 280 – 72
208.08 = 208
208 = 208 ✔
Plug both values back into the equation:
H (2x + 2) = 8 (x – 9)
2.89 (2(35) + 2) = 8 (35 – 9)
2.89 (70 + 2) = 8 (35 – 9)
Distributive Property:
2.89 (70 + 2) = 8 (35 – 9)
202.3 + 5.78 = 280 – 72
208.08 = 208 ✔
So, the correct answer is:
x = 35 and h = 2.89

Which stage of the Demographic Transition Model do you think the person is living in? and explain why.
Koji is 25 years old and an only child. He attends a local university for computer science. He lives with his mother, father, and grandparents who are over 100 years old. They recently celebrated their 75th wedding anniversary.
Since Koji is 25 years old and an only child and He attends a local university for computer science. The stage of the Demographic Transition Model do you think the person is living in is stage 4.
What are the 5 stages of the demographic transition?The Demographic Transition Model are:
Stage 1 - High Population Growth Potential.
Stage 2 -Population Explosion.
Stage 3- Population Growth Starts to Level Off.
Stage 4 - Stationary Population.
Stage 5 -some Changes in Birth Rates.
At stage 4, the rates of birth and death are both low. If a result, as birth rates fall below the "replacement level," or as families are having an average of less than two children each, the population may stay the same or even decline.
Therefore, one should anticipate that the generation born in the second stage of the demographic shift is currently aging. In the meantime, these aging people of society must be supported by the potentially declining working population.

-Eukaryotic cells
-Prokaryotic cells
-organelles
-nucleus
-nucleotides
-DNA
-Histones
-Chromosomes
Cells, which range from a single cell in bacteria to trillions in humans, are the building blocks of all living things. Each of these cells is a distinct structure covered by a cell membrane and filled with cytoplasm, a thick fluid. The majority of DNA in human cells is contained in a compartment within the cell known as the nucleus. It is referred to as nuclear DNA.
Where is the DNA located?Cells are widely classified into two types: those found in prokaryotes (prokaryotic cells) and those found in eukaryotes (eukaryotic cells). Prokaryotes are single-celled organisms that lack a membrane-bound nucleus and other membrane-surrounded structures known as organelles. They are divided into two groups: bacteria and archaea.
Single-celled or multicellular eukaryotes exist. Eukaryotic cells, unlike prokaryotic cells, have a nucleus and other organelles. Eukaryotes include species ranging from fungus to plants and animals.
DNA is mostly found in prokaryotic cells in a core section of the cell termed the nucleoid, which is not surrounded by a nuclear membrane. Most prokaryotes' genetic material takes the shape of a single circular DNA molecule, or chromosome.

1. Thirty-four college students were asked how much money they spent on textbooks for the current semester
Their responses are shown in the following stemplot.
A) From the information given, $810 is the outlier.
B) With regard to the distribution of money, it is correct to state that the distribution is skewed to the right.
What are Outliers?An outlier is a value in a random sampling from a population that is significantly different from the other values. In some ways, this interpretation leaves it up to the analyst (or a consensus process) to determine what is abnormal.
Analysis leading to the solution:
From the plot, the stems are given as:
Stems: 1 2 3 4 5 6 7 8
However, stem 7 does not have any leaf. Using the above information, the next entry after 620 is 810. 810 is relatively distant from the other datasets. Therefore 810 is an outlier.
With the above, it is correct to conclude that the distribution is skewed to the right.
It is to be noted that an outlier might imply faulty data. For example, the data may have been wrongly coded, or an experiment could have been done erroneously. If it is discovered that an outlying point is incorrect, the outlying value should be removed from the analysis (or corrected if possible).
