4. Do you think it would be useful to be able to predict future population? Why?
5. Identify factors that influence population growth?
6. Identify possible consequences of population growth.
Answers
4. Yes, it would be useful to be able to predict future population for a variety of reasons. Governments, businesses, and organizations can use population predictions to plan for future needs such as housing, healthcare, education, and transportation. Population predictions can also inform policy decisions related to immigration, national security, and environmental management.
5. Factors that influence population growth include:Birth rate: The number of births per 1,000 individuals in a population over a specified period of time.Death rate: The number of deaths per 1,000 individuals in a population over a specified period of time.Migration: The movement of people into or out of a population.Age structure: The proportion of individuals in different age groups within a population.Fertility rate: The average number of children born per woman in a population.Life expectancy: The average number of years a person is expected to live in a population.6. Possible consequences of population growth include:Strain on resources: As the population grows, there is increased demand for resources such as food, water, and energy, which can lead to scarcity and competition.Environmental degradation: Increased population can lead to deforestation, pollution, and habitat destruction, which can have negative effects on the environment and the species that inhabit it.Urbanization: As more people move to cities, there can be issues with overcrowding, traffic congestion, and housing shortages.Economic impacts: Population growth can have both positive and negative economic impacts, such as increased consumer demand and higher unemployment rates. Social and political impacts: Population growth can lead to social and political tensions, such as conflicts over resources and migration policies.5. Reproducing.
6. The world will be over populated. We will probably not have enough resources.
Aada saves and spends her salary at a ratio of 9:4. Find the percentage of her saving.
Answers
As you can see, 9 is greater than 4, so the percentage would be greater than 100%. You have to do 9 divided by 4 to find the percentage. Once you do that, you'll get 2.25, but that's just the decimal form. To find the percentage, you have to multiply by 100 which gives you 225%.

( determine the values of the unknowns that make the function continuous everywhere?)
Answers
Answer:
a = 4
b=-12
Step-by-step explanation:
For h(x) to be continuous, h(2) = -4 and h(5) = 8. a represents the slope of the line, which can be found using \(\frac{y_{2}-y_{1} }{x_{2}-x_{1}}\)=\(\frac{8-(-4)}{5-2} =4\), so a = 4.
Now we can use our known values and either point to solve for b.
Using h(2) = -4:
\(-4 = 4(2)+b\\b=-12\)
So, a = 4 and b = -12.
b=-12 hope it will help you

(x - 12) ÷ y + z =

Answers
Parenthesis operations are performed first.
If there is an exponential or radical number in the question, the second step is to solve these operations.
Then multiplication and division should be done.
Fourth, addition and subtraction must be done.
Also operations with the same priority are ordered from left to right.
First, let's put the given values in their places.
for x it is -23
for y it is -5
for z it is -10
( - 23 - 12) ÷ (-5) + (-10) // do the paranthesis first from left to right
-35 ÷ -5 -10 // then do the division

Please Help and Explain this like how do I calculate income tax and capital gain and investments
Answers
Answer: down below...
Step-by-step explanation:
Exercise 1:
Income = $83.465
Tax paid at 5.05% means, whatever your income is, you gotta pay 5.05% of it as a tax.
5.05% = \(\frac{5.05}{100}\)
\(\frac{5.05}{100}*$83.465\)
\(0.0505*$83.465\)
If you do the calculations it should give you a $4,214.9825 tax
"Income tax paid at 9.15%"
\(\frac{9.15}{100}*83.465\)
\(0.0915*83.465\)
The 9.15% tax = $7,637.0475
"Total income tax paid"
This will just be the sum of the two taxes.
$4,214.9825+$7,637.0475 = $11,852.03 (sum of taxes)
Exercise 2:
Purchase price = $347.000
Selling price = $863.000
As you can see, they purchased the property for $347.000 and sold it for $863.000 which made them a lot of money in profit :)
That's what the Difference is.
Difference = $863.000-$347.000
Difference = $516,000
I don't really understand what capital gains are, because I'm 13, but I suppose I gotta calculate 50% of the profit that the banker has made.
\(\frac{50}{100}*$516.000\)
\(\frac{5}{1}*$51.600\)
\(5*$51.600\)
"Capital gains" = $258,000
I don't really know if this is the correct answer for capital gains, but I am pretty sure I did well on the other ones.
Hope I helped you :] !

Deanna gets 3 problems incorrect on her quiz. Her score is 85%. How many questions are on the quiz?
Answers
Let's start by seeing what percentage is incorrect.
100-85=15
So, 15% is incorrect when answering 3 problems wrong. So let's divide 15 by 3.
15÷3=5
So, each problem is worth 5%, let's divide 100 by 5. The reason I'm doing this is to find out how many questions are on the quiz since if you got them all right, it's 100.
100÷5
20
There are 20 questions, let's make sure this is correct.
If she got 3 wrong, she got 17 right. Let's calculate her percentage and make sure it is the right one.
17÷20
.85×100
85%
Answer: So, there are 20 questions on the math quiz.
Answer:
20 questions
Step-by-step explanation:
Deanna got 15% incorrect

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.
