Answer:
Step-by-step explanation:
The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.

58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 50° is added to the data, how does the median change?
The median decreases to 77°.
The median decreases to 65.2°.
The median stays at 82°.
The median stays at 79.5°.
Answer: The median decreases to 77°.
Step-by-step explanation:
1. First step is to order all the numbers from least to greatest.
50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
2. Second step is to find the middle number
50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
3. The middle number is the answer so in this case the median is now 77 which means the answer is the first choice.

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

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.
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.Which expression is equivalent to −1/4x+1/2?
A. −1/4(−x+1/2)
B. 1/4(−x+1/2)
C. 1/4(−x+2)
D. −1/4(x+2)
Answer: D. −1/4(x+2)
Step-by-step explanation: The expression -1/4x + 1/2 can be simplified by factoring out 1/4, which gives -1/4(x - 2).
Therefore, the expression that is equivalent to -1/4x + 1/2 is D. -1/4(x+2).
Doug left home for his destination and drove for the first 2 hours on a state road at a constant rate of 50 miles per hour. For the next 3 hours, he drove on an interstate highway at a constant rate of 60 miles per hour. How many miles from home was he when he arrived at his destination 5 hours later?
_______miles
Answer: In the first 2 hours, Doug drove 2 * 50 = <<250=100>>100 miles on the state road.
In the next 3 hours, he drove 3 * 60 = <<360=180>>180 miles on the interstate highway.
Therefore, he drove a total of 100 + 180 = <<100+180=280>>280 miles.
Since we don't know his distance from home before he began driving, we cannot calculate his distance from home after 5 hours of driving.

A makeup artist purchased some lipsticks and wants to wrap them individually with gift wrap. Each lipstick has a radius of 0.4 inch and a height of 2.2 inches. How many total square inches of gift wrap will the makeup artist need to wrap 3 lipsticks? Leave the answer in terms of π.
2.08π square inches
6.24π square inches
8.32π square inches
19.59π square inches
Answer:
[tex]6.24\pi \: {in}^{2} [/tex]
Step-by-step explanation:
Given:
r (radius) = 0,4 in
h (height) = 2,2 in
n (the number of lipsticks) = 3
Find: A (total surface area) - ?
First, we have to find how much gift wrap will the makeup artist need to wrap one lipstick:
[tex]a(surface1) = 2\pi {r}^{2} + 2\pi \times r \times h[/tex]
[tex]a(surface1) = 2\pi \times ({0.4})^{2} + 2\pi \times 0.4 \times 2.2 = \frac{52\pi}{25} [/tex]
Now, let's multiply this number by the quantity of lipsticks the makeup artist has to wrap:
[tex]a(total) = \frac{52\pi}{25} \times 3 = \frac{156\pi}{25} = 6.24\pi \: {in}^{2} [/tex]
