Answer:
An observational study
Explanation:
observational studies are those a study where the researcher observes the effect of a defy factor, diagnostic test, treatment or other intervention without trying to change who is or isn't exposed to it. Cohort study and control studies are of two observational studies. These are the part of fundamental of epidemiological research. These are called observational studies because the investigators observe individuals without manipulation and intervention. These studies are an important category of study design. Well, design observational studies maybe the next best method to address these types of questions.
For this case we have the following function:
When evaluating x = 2 in the given function we have:
Rewriting we have:
Therefore, the pair ordered for this point is given by:
The ordered pair of the table for x = 2 is:
Therefore, the table is incorrect for x = 2
Answer:
The row in the table is incorrect for:
x=2
Answer:
<ABC = 27
< BAC = 126
Step-by-step explanation:
<C = <B since it is an isosceles triangle. We know this since AC - AB
<C = 27 so <ABC = 27
The sum of the angles of a triangle = 180
A + B+ C = 180
A + 27+27 = 180
A + 54 =180
A = 180-54
A =126
< BAC = 126
What do you mean? At first it was 4 times as old, then it's twice her age?
