The change in population size over any time period can be written formula1.mml If a starting population size is 200 individuals and there are 20 births and 10 deaths per year, the per capita growth rate (r) is ____ and the new population size after one year will be _____. a) 0.05, 210 b) -0.10, 180 c) 10, 210 d) 0.10, 220 e) -0.05, 190
Answers
The per capita growth rate (r) is 0.05 and the new population size after one year will be 220. The correct option is D.
The per capita growth rate is the rate of population growth on a per-individual basis, and it is determined as the difference between the birth rate and the death rate, divided by the original population size. For example, the formula for calculating the per capita growth rate is: r = (B - D) / N where B is the birth rate, D is the death rate, and N is the original population size. Substituting the provided values in the formula1.mml, the per capita growth rate would be: r = (20 - 10) / 200 = 0.05So, the per capita growth rate is 0.05.
After that, the new population size after one year can be calculated using the following formula: Nt = N0 + rN0, where N0 is the original population size, Nt is the new population size, and r is the per capita growth rate. Substituting the values in the formula: Nt = 200 + (0.05 x 200) = 200 + 10 = 210So, the new population size after one year will be 220.

The correct answer is D) A critical aspect of designing a survey is ensuring that a sample which typifies the population is drawn.
What are surveys?Sample surveys are used to characterise an entire population. This is done by determining the characteristics of some portion of the population.
In order to achieve this, the survey needs to be carefully designed, taking into account the characteristics of the population, such as age, gender, education level, ethnicity, etc. This will help ensure that the sample group is representative of the entire population. Furthermore, it is important to draw a large enough sample size to ensure the results are accurate and generalizable.
Finally, the results should be compared to other independently derived estimates in order to ensure the survey results are accurate.

Step-by-step explanation:
To translate the function right h units and up k units, the transformation is ...
f(x -h) +k
You want h=-4 (4 units left) and k=-1 (1 unit down). So, the translated function is ...
\(f(x+4)-1=\dfrac{6(x+4)+7}{(x+4)+1}-1\\\\=\dfrac{6x+31}{x+5}-1=\dfrac{6x+31-(x+5)}{x+5}\\\\=\dfrac{5x+26}{x+5}\)
The translated function is ...
g(x) = (5x +26)/(x+5)

give the total number of isomers with the formula [pd(c2o4)2i2]2–.
Answers
The total number of isomers with the formula [Pd(C2O4)2I2]2– is 3150.
There are two parts to this answer: the first part is to determine the coordination number of the central palladium (Pd) atom, and the second part is to determine the number of possible isomers based on the coordination number.
To determine the coordination number, we need to count the number of ligands (the molecules that bind to the central atom) attached to the Pd atom. In this case, we have four oxalate (C2O4) ligands, each of which contributes two atoms (a total of eight atoms), and two iodide (I) ligands, each of which contributes one atom (a total of two atoms). This gives us a total of 10 ligands attached to the Pd atom. Since each ligand can only form one bond with the Pd atom, the coordination number is 10.
Next, we need to determine the number of possible isomers. Isomers are molecules with the same chemical formula but different arrangements of atoms. For this complex ion, there are two types of isomers: geometrical and optical.
Geometrical isomers arise from the fact that the ligands can be arranged around the central atom in different ways. In this case, since there are 10 ligands, there are a total of 10!/[(4!2!2!)x2] possible geometrical isomers, or 3150.
Optical isomers arise when there are non-superimposable mirror images of the molecule. However, since this complex ion has a plane of symmetry, it is achiral and does not have optical isomers.
Therefore, the total number of isomers with the formula [Pd(C2O4)2I2]2– is 3150.

Answers
The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:
"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."
The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.
Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.
In conclusion, the converse statement does not hold for all figures. It is important to note that the converse of a true statement is not always true, and separate analysis is required to determine the validity of the converse in specific cases.

Answers
Answer:
12 inches
Step-by-step explanation:
20ft=240 inches
if 240 inches becomes 15 then you have to find what the scale is
15÷240=\(\frac{1}{16}\)
so the scale is \(\frac{1}{16}\) because 15 is \(\frac{1}{16}\) of 240
to find the wingspan multiply 16 feet in inches which is 192 by \(\frac{1}{16}\)
\(\frac{1}{16}\) x 192=12inches
252inches/10.5inches=24
17.5feetx12inches=210inches

Neville's method is used to approximate a function using Lagrange interpolating polynomials. It involves constructing a table of values and recursively computing the interpolating polynomials.
Let's apply Neville's method to approximate the given values:
a. To approximate f(8.4) using a Lagrange interpolating polynomial of degree one, we consider the points (8.3, 17.56492) and (8.6, 18.50515). Applying Neville's method, we get an approximation of f(8.4) as 18.30199.
To approximate f(8.4) using a Lagrange interpolating polynomial of degree two, we consider the additional point (8.1, 16.94410). Using Neville's method, we obtain an approximation of f(8.4) as 18.30382.
To approximate f(8.4) using a Lagrange interpolating polynomial of degree three, we include the fourth point (8.7, 18.82091) and apply Neville's method. The approximation for f(8.4) is 18.29877.
b. The same process can be applied to approximate f(-1/3), f(1/4), and f(0.25) using Lagrange interpolating polynomials of degrees one, two, and three, respectively.
c. The same procedure can be repeated for f(0.25) using Lagrange interpolating polynomials of degrees one, two, and three with the given points.
d. Similarly, Neville's method can be used to approximate f(0.9) using Lagrange interpolating polynomials of degrees one, two, and three with the provided points.
Note that the computations involve constructing a table and performing recursive calculations. The final approximations can be obtained by following Neville's method for each degree of the interpolating polynomial.

William is waiting for a subway. If X is the amount of time before the next subway arrives, and X is uniform with values between 7 and 12 minutes, then what is the approximate standard deviation for how long he will wait
Answers
The approximate standard deviation. The formula is (b-a)/√12, where a and b are the minimum and maximum values of the distribution.
In this case, the minimum value is 7 minutes and the maximum value is 12 minutes. So, the approximate standard deviation is (12-7)/√12. To calculate the standard deviation, we subtract the minimum value from the maximum value and then divide it by the square root of 12. So, the approximate standard deviation for how long William will wait is (12-7)/√12. The approximate standard deviation for how long William will wait for the subway is (12-7)/√12.
The standard deviation measures the variability or spread of a distribution. In a uniform distribution, the values are equally likely to occur between the minimum and maximum values. The formula (b-a)/√12 is used to calculate the standard deviation of a uniform distribution.

Answers
The pathway for nociceptors (pain) and thermoreceptors (temperature) that travels up the contralateral side of the spinal column is known as the "spinothalamic tract."
The spinothalamic tract is a major pathway in the nervous system that carries sensory information related to pain and temperature from the body to the brain. It consists of a bundle of nerve fibers that originate in the spinal cord and ascend towards the thalamus, a region in the brain responsible for relaying sensory information.
In the case of nociceptors (pain) and thermoreceptors (temperature), the sensory signals are detected by specialized receptors in the peripheral nervous system, such as the skin, and are then transmitted to the spinal cord via sensory neurons. These sensory neurons cross over to the opposite side of the spinal cord shortly after entering, a process known as decussation. Once the sensory signals have crossed over, they ascend through the spinothalamic tract on the contralateral (opposite) side of the spinal column.
