Answer:
Theoretical --- probability is based on expected or calculated results.
Experimental --- probability is based on the actual recorded results of an experiment.
Step-by-step explanation:
Theoretical assumptions are those hypotheses not proven to be real, whose probabilities of materializing depend on the future confirmation of the premises established. Thus, these theories are established based on different experiences and previous situations, or based on data still not scientifically proven.
Instead, the experimental results are those that have already been confirmed based on tests, tests and experiments that affirm or deny the previously established theories.
Answer: PQR=32
Step-by-step explanation:
RQS+PQR=PQS
(4x+4)+(3x-1)=80
7x+3=80
7x=77
x=11
PQR=(3x-1)=> (3(11)-1) => 33-1=32
