Which of the following statements best describes a characteristic of an observational study?
The researcher determines relationships among variables.
The individuals are observed the exact way they act in real life.
The researcher imposes, for example, a treatment on the sample population and then observes their response.
It is the best method to learn about cause-effect relationships.
Answers
Answer:
The researcher determines relationships among variables.
The individuals are observed the exact way they act in real life.
Step-by-step explanation:
An observational study can be defined as a type of study in which a researcher observes and measures the effect of a diagnostic test, risk factors, or treatments on individuals without intervening, changing or manipulating who are or aren't exposed to it (controlled conditions).
Hence, the statements which best describes a characteristic of an observational study are;
I. The researcher determines relationships among variables.
II. The individuals are observed the exact way they act in real life.
Additionally, an unobtrusive data collection is a data collection technique used mainly in the social sciences to obtain or gather data without the researcher directly interfering or interfacing with the subject being studied. Thus, it doesn't influence the behavior, action or response of the subjects under study.

Answers
Answer: See the attached image
You have the correct idea for the boxes you've filled out. For the first three boxes in column 1, I would be specific which segments you are dividing. So for instance, in the first box, it would be EG/EB = 55/11 = 5. Then the second box would be EF/EC = 35/7 = 5, and so on. The order of the boxes doesn't matter. The three boxes then combine together to help show that the triangles are similar. Specifically [tex]\triangle EFG \sim \triangle ECB[/tex]. The order of the letters is important to help show how the angles pair up and how the sides pair up. We use the SSS similarity theorem here.
The second problem is the same idea, but we use one pair of congruent angles. So we'll use the SAS similarity theorem this time.

determine the value of a cube with side length of 2 and 1/4 cm
Answers
Answer:
6 3/4 cm³
Step-by-step explanation:
I'm assuming value means volume, so if I'm wrong, let me know ;).
To find volume, you multiply length x height x width. So you multiply 2 1/4 three times.
Convert 2 1/4 to an improper fraction.
2 1/4 = 9/4
9 x 3 27
-- -- =
4 x 1 4
Now convert 27/4 to a mixed fraction.
27/4 = 6 3/4
So the volume of the cube is 6 3/4 cm³.

The half-life of Iodine-131 is approximately 8 days. Find the amount of Iodine-131 left from a 42 gram sample after 16 days.
1) 0.0006 grams
2) 21 grams
3) 10.5 grams
4) 34 grams
Answers
Answer:
Step-by-step explanation:
The formula for this is
[tex]N=N_0(.5)^{\frac{t}{H}[/tex] where
N is the amount of the element left after a certain amount of time (for us it is measured in days),
N₀ is the initial amount of the element in grams,
t is the number of days gone by, and
H is the half life of the element. Filling in:
[tex]N=42(.5)^{\frac{16}{8}[/tex] which simplifies a bit to
[tex]N=42(.5)^2[/tex] and a bit more to
N = 42(.25) which gives us a remaining amount of
N = 10.5

3x + 2 = 17
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15[Division Property of Equality] Divide 3 on both sides: x = 5Answer:
you subtract two both side, then divide three both side, you'll get x = 5.
Step-by-step explanation:
3x + 2 = 17
(3x + 2) -2 = (17) -2. First, you subtract 2 for both sides
3x = 15
(3x)/2 = (15)/2. Second, you divide 3 both side
x = 5. Last, you get your answer
