Answer:
Step-by-step explanation:
1) Sample space - the set of all possible outcomes for an experiment
2) Theoretical probability - A ratio representing the likelihood of an event
3) Uniform probability model - A probability model in which each of the outcomes in the sample space are equally likely, or have the same probability
Hope it helps :))
Answer:
The regular price was $53.85
Step-by-step explanation:
78% = $42

Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with 
sides is given by:-
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. 
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Answer:
No roots
Step-by-step explanation:
the discriminant Δ = 12²-4×(-10)×(-9) = -216
since ∆ is negative then the equation -10x^2 + 12x − 9 = 0 has no solution .
