Scott paints fences for $300 each. If he paints 8 fences, how much money does he make? Discrete or continuous

Answer: 2400 dollars for the 8 fences
h (2x + 2) = 8(x-9) find h
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

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).

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.

Humans care for their children longer than most other species. Over the past couple of decades, teenagers have stayed in their family's homes longer than previous generations. Can this trend be attributed to the evolution of traits concerning survival? Why or why not?
Teenagers staying in their family's homes longer than previous generations can't be attributed to the evolution of traits because it isn't inherited and it's just a choice.
What is Evolution?This is referred to as the changes which occurs in the inherited traits of a population of organisms through successive generations and increases the chances of survival.
The trend which is about teenagers staying in their family's homes longer than previous generations is just a decision in the way parents of the present generation have loosened up in ensuring their children are independent before leaving their home in other to prevent negative effects such as crime etc.

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.
