Answer:
Option c
Step-by-step explanation:
The study is an observational study. An observational study is made when the researchers collect data based on what they see, hear or observe without any form of manipulation or treatment plan from the researchers. Thus, in this case, the study is an observational study because the study examines individuals in a sample, but does not try to influence the response variable/influence their responses.
Answer:Angles 1 and 3 are vertical angles
Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
A terminating decimal differs from a repeating decimal in that ; terminating decimals have a finite number of numbers after a decimal point whereby repeating decimals Don not have a fine number of numbers after the decimal point.
Given :
A. 2/7 = 0.2857...
B. 3/2 = 1.5
C. 2/3 = 0.6666...
D. 3/5 = 0.6
E. 5/9 = 0.5555...
B and D are terminating decimal values.
As the sine rule states,
A/sina = B/sinb = C/sinc .
in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.
there are:
side a, with angle â .
side b, with angle b.
so the answer is C.
if you input these into the sine rule, it would be:
a/ sin a = b/sin b
