Answer: Experimental Probability
Step-by-step explanation:
Theoretical Probability is the theory behind probability. Experimental (empirical) probability is probability calculated during experiments, direct observation, experience, or practice. The empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
One less than twice a number is seventeen.
Answer:
75%
Step-by-step explanation:
First find the number of boys.
80 - 20 = 60
Now find the percentage my taking the number of boys upon the total, times that by 100 which gives the percentage.
× 100 = 75%
Answer:
Resultant vector of two vectors is (0, 0).
Step-by-step explanation:
in this question two vectors having ordered pair (-6, 5) and (6, -5) have been given.
We can represent these vectors in the form of

and 
Now the resultant of these vectors will be = A + A'
A + A' =
+ 
So the resultant vector = (0 + 0)
Therefore the resultant will be (0, 0)
