Final answer:
In biology, the population refers to all individuals of a species in an area. For the humpback whale study, the population is the specific pod of whales being studied, not all whales or humpback whales in general. This aligns with population ecology principles.
Explanation:
The population in a biology context refers to all the members of a single species living in a particular area. In the given scenario where a scientist studies a pod of humpback whales to determine the migration of humpback whales, the correct answer would be B. a pod of humpback whales. This is because the scientist is studying a specific group of humpback whales, which constitutes a population within the larger population ecology context of all humpback whales.
Population ecology is a field that focuses on the number of individuals of one species in an area and how and why that number changes over time. It helps in understanding different aspects of species like their migration patterns, social structures, and interaction with the environment. A pod of humpback whales would be considered a distinct population if they are living together in the same space and are interbreeding, as per the definition of a population in this biological field.
There are 8 green, 10 purple, 6 red and 16 blue markers in a box. A marker is chosen,replaced and then another marker is chosen. Find the probability that neither marker is red.
The probability that neither marker chosen from the box is red is 72.25%
Explanation:The probability that neither marker chosen is red can be calculated by finding the probability of not picking a red marker twice. There are a total of 40 markers (8 green, 10 purple, 6 red, and 16 blue). Therefore, the probability of not picking a red marker on the first try is 34/40 or 0.85 (since there are 34 non-red markers).
Because the marker is replaced, the conditions remain the same for the second draw. Hence, the probability of also not picking a red marker in the second draw remains at 0.85.
As these are two independent events, the total probability of neither marker being red is found by multiplying the probabilities of the individual events. Hence, 0.85 * 0.85 = 0.7225. Hence the probability that neither marker is red is 0.7225 or 72.25%.

To find the probability that neither marker is red, calculate the probability of selecting a non-red marker on each draw and multiply the probabilities together.
Explanation:To find the probability that neither marker is red, we need to calculate the probability of selecting a non-red marker on each draw.
The total number of markers in the box is 8 (green) + 10 (purple) + 6 (red) + 16 (blue) = 40.
The probability of selecting a non-red marker on the first draw is (8 + 10 + 16)/40 = 34/40 = 17/20.
Since the marker is replaced back in the box, the probability of selecting a non-red marker on the second draw is also 17/20.
The probability that neither marker is red is the product of the individual probabilities: (17/20) * (17/20) = 289/400.

Find the mean, median, and mode of 3, 5, 1, 5, 1, 1, 2, 3, 15.
Answer:
Mean: 4
Median: 3
Mode: 1
Step-by-step explanation: For the mean, you have to add all the numbers and divide it by the amount of numbers there are to find the average (mean). For the median, you have to order the numbers from least to greatest and since there are 9 numbers and 9 is an odd number, you have to see which number is in the middle, 3 was in the middle for this problem. The mode is which number repeats the most, which was 1.
Answer:
Mean = 4, Median = 3, Mode = 1
Step-by-step explanation:
The mean is also the average. To find it you add all the numbers up and divide that by the # of numbers given.
[tex]\frac{3+5+1+5+1+1+2+3+1+5}{7} =\frac{28}{7}=4[/tex]
Median is the middle number when all the numbers are written out numerically including the doubles
1 1 1 2 3 3 5 5 15
Mode is the number that appears the most
in this case it is 1
A population of 110,000 grows 3% per years 15 years. How much will the population. How much will the population be after 15 years? Terms of x
Answer:
The population be after 15 years is 171376.
Step-by-step explanation:
Given : A population of 110,000 grows 3% per years 15 years.
To find : How much will the population be after 15 years?
Solution :
Exponential growth population model is given by,
[tex]P(t)=P_o(1+r)^t[/tex]
Where,
P(t) is the population at time (t)
[tex]P_o=110,000[/tex] is the initial value of the population
r=3%=0.03 is the annual rate of growth
t=15 is the time in years.
Substitute the value,
[tex]P(t)=110000(1+0.03)^{15}[/tex]
[tex]P(t)=110000(1.03)^{15}[/tex]
[tex]P(t)=110000\times 1.5579[/tex]
[tex]P(t)=171376.41[/tex]
Therefore, the population be after 15 years is 171376.
Final answer:
The future population after 15 years of 3% annual growth starting with a population of 110,000 is calculated using the exponential growth formula, resulting in approximately 171,380 people.
Explanation:
To calculate the future population given a current population, growth rate, and number of years, you can use the formula for exponential growth:
P(t) = P0 ×[tex](1 + r)^{t}[/tex]
Where:
P(t) is the population after t years.
P0 is the initial population.
r is the annual growth rate (expressed as a decimal).
t is the time in years.
In this case, the initial population (P0) is 110,000, the growth rate (r) is 3% or 0.03, and the time (t) is 15 years.
Applying these values to the formula:
P(15) = 110,000 × (1 + 0.03)¹⁵
Now we compute the amount (rounded to the nearest whole number):
P(15) = 110,000 × 1.03¹⁵
P(15) ≈ 110,000 × 1.558
P(15) ≈ 171,380
Therefore, the population after 15 years will be approximately 171,380 people.

if you ate 5 out of the 20 slices of pizza , how many slices of pizza would you eat if there are 120 slices of pizza?
Answer:
30 slices
Step-by-step explanation:
Make a proportion
You ate 5 out 20 slices, and x out of 120 slices
5/20=x/120
Multiply both sides by 120 to get x by itself
120(5/20)=(x/120)120
The 120s on the right will cancel out, and we are left with
30=x
So, you would eat 30 slices of pizza out of 120 slices

The locus of points idea allows you to define geometric objects just by determining whether or not two distances are equal.
Answer:
True
Step-by-step explanation:
Final answer:
The statement is True: the locus of points concept is used in geometry to define shapes based on the equality of distances, such as an equidistant curve from a line, or a circle at a fixed distance from a point.
Explanation:
The statement "The locus of points idea allows you to define geometric objects just by determining whether or not two distances are equal" is True. The locus of points is a concept in geometry that represents a set of points that satisfy certain conditions. For instance, the locus of points at a given distance from a straight line is known as an equidistant curve, and when this distance is from a point, it forms a circle. Euclidean geometry often assumes that distances are consistent and measurable, idealizing the real world where we use rules and compasses to define distances and constructs. Concepts like parallelism and measurement systems, as found in axioms, help to build an understanding of geometric relations on lines. Moreover, the validity of geometric propositions can be questioned in real-world applications as geometry serves as an abstraction of physical space.
Lucia and Marcus are playing a board game. They roll 2 dice (number cubes) to see who goes first. The person who rolls the highest sum gets to go first. If there is a tie, they each roll the dice again. Lucia went first and she rolled a 4 and a 1. Find the probability that Marcus will not get to go immediately after he rolls the dice. Show all of your work below. Express your answer as a fraction in simplest form, a decimal and a percent
Answer:
5/18, 0.278, 27.8%
Step-by-step explanation:
In this problem, we basically want to find the probability that Marcus will have a total sum of the 2 dices less than Lucia.
In her throw, Lucia gets a 4 and a 1, so she gets a total sum of 5.
Therefore, we want to find the probability that Marcus will get 5 or less.
The possible combinations that can be obtained when throwing 2 dices are 36 (6 x 6).
Of all these 36 combinations, those that gives a sum of 5 or less are:
1 +1 = 2
1 + 2 = 3
2 + 1 = 3
1 +3 = 4
3 + 1 = 4
1 + 4 = 5
4 + 1 = 5
2 + 2 = 4
2 + 3 = 5
3 + 2 = 5
So, a total of 10 combinations.
Since the probability of an event is:
[tex]p(A)=\frac{s}{n}[/tex]
where
s is the number of successfull outcomes
n is the number of total possible outcomes
Here we have
s = 10
n = 36
Therefore the probability here is
[tex]p=\frac{10}{36}=\frac{5}{18}=0.278 = 27.8\%[/tex]

Look at the figure. Find the length of JP.
A.) 8
B.) 2
C.) 4
D.) 6
By using the provided scale factor of 2, we multiply the side length of the first square by 2 to find that the length of JP is 8 inches.
Explanation:To find the length of JP, we must consider the information given about the dimensions of the larger square. Since the problem states that the dimensions of the larger square are twice that of the first square, we know there is a scale factor of 2 involved in the sizing of the squares. Thus, if the side length of the first square is 4 inches, the side length of the larger square would be 4 inches × 2 = 8 inches.
