Answer:
Logistic growth is like growth statistics only known when the population size is affected by limited resources. Logistic growth is a mix of math and science, and comes helpful for studying populations.
One example of logistic growth formula is f(P) = rP(1 - P / K)
Where K is your relative growth rate co-efficient(only when K is lowercased. Otherwise, K is carrying capacity.)
And P is your initial population.

The sampling method that would be most likely to result in self-selection bias is given by:
D. handing out a questionnaire to seniors only
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, in option D, only seniors are involved, that is, it does not involve all segements, hence it would be most likely to result in self-selection bias.

Sarah makes home-made jewelry sets. Each jewelry set includes a necklace, a bracelet and two earrings. Given below are the number of beads Sarah adds to each type of jewelry.
Necklace: 48
Bracelet: 19
Earrings: 6 (both earrings combined)
What is the largest number of jewelry sets she can make with 7100 beads?
Based on the number of beads that are needed to make a jewelry set, the largest number of jewelry sets that Sarah can make with 7,100 beads is 97 jewelry sets.
What amount of jewelry sets can Sarah make?First find the total number of beads used per jewelry set:
= Necklace + Bracelet + Earrings
= 48 + 19 + 6
= 73 beads
If she had 7,100 beads, the sets she could make would be:
= Total number of beads / Beads per set
= 7,100 / 73
= 97 jewelry sets

Problem 22: [tex]m[/tex] = [tex]1[/tex]
Problem 23: [tex]m[/tex] = [tex]3[/tex]
Step-by-step explanation:
The formula to find the slope of a line: [tex]m = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex].
Problem 20:
1) Substitute the values into the formula and solve it.
[tex]m[/tex] = [tex]\frac{3-7}{2-4}[/tex]
[tex]m[/tex] = [tex]\frac{-4}{-2}[/tex]
[tex]m[/tex] = [tex]2[/tex]
Problem 21:
1) Substitute the values into the formula and solve it.
[tex]m[/tex] = [tex]\frac{-5-1}{2--1}[/tex]
[tex]m[/tex] = [tex]\frac{-6}{3}[/tex]
[tex]m[/tex] = [tex]-2[/tex]
Problem 22:
1) Substitute the values into the formula and solve it.
[tex]m[/tex] = [tex]\frac{3-7}{-6--2}[/tex]
[tex]m[/tex] = [tex]\frac{-4}{-4}[/tex]
[tex]m[/tex] = [tex]1[/tex]
Problem 23:
1) Substitute the values into the formula and solve it.
[tex]m[/tex] = [tex]\frac{-4-2}{-4--2}[/tex]
[tex]m[/tex] = [tex]\frac{-6}{-2}[/tex]
[tex]m[/tex] = [tex]3[/tex]
*Extra*: The equation of a line is written in this form: [tex]y = mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is [tex]y[/tex]-intercept
In a random sample of 2500 sports fans, 61% prefer basketball over soccer.
What is the Margin of error in this survey?
Margin of error = [m]%
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.
What is the margin of error?The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,
[tex]MOE=\sqrt{\dfrac{\hat p(1-\hat p)}{n}} = \sqrt{\dfrac{0.61(1-0.61)}{2500}} = 0.00975 = 0.975\% \approx 1\%[/tex]

Find the surface area and volume of the figure.
Step-by-step explanation:
this is again a combined object.
at the bottom there is a cylinder.
and on top there is half of a sphere (I assume it is a sphere, because there is no additional information about its height, and we could therefore not solve this otherwise).
for the total volume we need to calculate both volumes and add these results.
for the total surface area we need to calculate both surface areas, but remove the top surface area of the cylinder, because the half-sphere is covering it.
so, let's start with the volume :
the volume is a cylinder is
ground area × height = pi×r² × height
the radius is half of the diameter, so, r = 18/2 = 9 ft.
in our case that gives us
pi×9² × 10 = pi×81 × 10 = 810×pi = 2,544.690049... ft³ ≈
≈ 2,544.7 ft³
the volume of a sphere is
pi×r³ × 4/3
and of a half-sphere therefore
pi×r³ × 4/3 / 2 = pi×r³ × 2/3 = pi×9³ × 2/3 = pi×9² × 2 =
= pi×81 × 2 = 162×pi = 508.9380099... ft³
≈ 508.9 ft³
the total volume is then
3,053.628059... ft³ ≈ 3,053.6 ft³
the surface area :
the surface area of a cylinder is
the areas of the circles on the top and the bottom (but here we need only the bottom) plus the area of the lateral side area, the "mantle", which is the circumference of the basic circle times height.
so, in our case we get
pi×r² + 2×pi×r×height
pi×9² + 2×pi×9×10 = 81pi + 180pi = 261pi =
= 819.9556826... ft² ≈ 820 ft²
the surface area of a sphere is
4×pi×r²
and therefore if a half-sphere
4×pi×r² / 2 = 2×pi×r²
in our case
2×pi×9² = 2×pi×81 = 162pi = 508.9380099... ft²
≈ 508.9 ft²
the total surface area is then
1,328.893692... ft² ≈ 1,328.9 ft²
