Answers
Answer:
1. Unbiased sample.
2. Self-selected sample.
3. Stratified sample.
4. Systematic sample.
5. Convenience sample.
6. Biased sample.
Step-by-step explanation:
1. Unbiased sample: sample where every member of the population has an equal chance of being selected.
For example, a researcher randomly selecting a shopping mall and questioning the customers coming there.2. Self-selected sample: sample where members volunteer to take part.
For example, a researcher uploading a questionnaire online and then requesting for brainly members to take part.3. Stratified sample: members are selected from the different subgroups within a population.
For example, when a geographical region is stratified into subgroups by climate, habitat, soil type or elevation. A population grouped by males or females.4. Systematic sample: sample members are selected through the use of a rule.
For example, a researcher selecting the 10th house on a particular street.5. Convenience sample: sample where representatives are easily accessible.
For example, a researcher using a social media poll such as Twitter polls.6. Biased sample: sample not representative of the entire population.
For example, a researcher selecting only females when trying to determine the best cook in a class.Answer:
1. biased sample

A 12 cm by 20 cm painting hangs in a museum. The museum curator wants to hang other paintings in the gallery that are proportional in size. The dimensions of several paintings are shown. Which paintings' dimensions are proportional to the original painting? Select all that apply. A. 1.5 cm by 2.5 cm B. 27 cm by 45 cm C. 9 cm by 15 cm D. 30 cm by 50 cm E. 6 cm by 14 cm
Answers
Answer:
A. 1.5 cm by 2.5 cm
B. 27 cm by 45 cm
C. 9 cm by 15 cm
D. 30 cm by 50 cm
Step-by-step explanation:
The dimensions of the original painting = 12 cm by 20 cm painting
Hence, the proportion is:
12/20 = 0.6
Hence, we compare the options given in the question.
A. 1.5 cm by 2.5 cm
= 1.5/2.5 = 0.6 , option A is correct
B. 27 cm by 45 cm
27cm/45 cm = 0.6 Option B is correct
C. 9 cm by 15 cm
9cm/15cm = 0.6 , Option C is correct
D. 30 cm by 50 cm
30 cm /50 cm = 0.6 Option D is correct
E. 6 cm by 14 cm
6cm/14 cm = 0.4285714286
Option E is not correct
Therefore, Options A to D are the correct options

Can I plz get the congruence and reason plz
Answers
Congruence is when there are 2 objects that have the same shape and size, or they "mirror" each other.
Question 6:
Congruence:
Yes, these two objects are congruent.
Reason:
They are congruent, because they have the same size and shape, or that they "mirror" each other.
Question 7:
Congruence:
Yes there is congruence, here. These two objects are similar shapes, but not completely congruent.
Reason:
These two objects have the same size, but not the exact same shape. If you look at point B you can see that the two angles are different, which means that they are similar shapes, but not completely congruent.
Hope this helps! :)
here's the question for is you can't see.
what is the vertex of the equation below?
y=2(x-3)>2+4
1. (2,4)
2. (-3,4)
3. (-2,4)
4. (3,4)
Answers
From [tex]y=a(x-h)^2+k[/tex]
The vertex is at (h, k)
Therefore, from [tex]y=2(x-3)^2+4[/tex]
The vertex is at (3,4).
Thus, the answer is 4. (3,4)
Part 1: Explain what the following variables represent and how changing each one affects the monthly payment amount: P, i, and t.
Part 2: Explain how changing each variable (P, i, and t) affects the total cost of principal and interest over the life of the loan.
Answers
Answer:
Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is StartFraction 2 Over 9 EndFraction of an inch thick, which expression can be used to determine the number of books that will fit into the box? 18 2/9 18 times 2/9 2/9 divided by 18 9/2 divided by 18
Answers
Answer:
A. 18÷2/9
Step-by-step explanation:
A. 18÷2/9
B. 18×2/9
C. 2/9÷18
D. 9/2÷18
Let
Total length of box = 18 inches
Thickness of each book = 2/9 inches
Number of books that will fit into the box = x
Number of books that will fit into the box = Total length of box ÷ Thickness of each book
x = 18 ÷ 2/9
= 18 × 9/2
= 162/2
= 81 books
The correct answer is A. 18÷2/9

[tex]( \sin^{2} ( \frac{\pi}{ 4 } - \alpha ) ) = \frac{1}{2} (1 - \sin(2 \alpha ) )[/tex]
Prove
Answers
Step-by-step explanation:
[tex] \sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Use the identity
[tex] \sin^2 \theta = \dfrac{1 - \cos 2\theta}{2} [/tex]
on the left side.
[tex] \dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Now use the identity
[tex] \sin \theta = \cos(\frac{\pi}{2} - \theta) [/tex]
on the left side.
[tex] \dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
