Answer:
∠B = ∠C = 138°
∠D = 42°
Step-by-step explanation:
Angles between the parallel bases are supplementary:
∠B = 180° -∠A = 180° -42° = 138°
Right-side angles are the same measure as their mirrors across the line of symmetry.
∠C = ∠B = 138°
∠D = ∠A = 42°
Answer:
As the sample size increases, the relative frequency of outcomes gets closer to the theoretical probability of the outcome.
Step-by-step explanation:
In small sample sizes, the relative frequency of outcomes may be far from the theoretical probability. However, as the sample size increases, these probabilities get closer. This is the law of large number.
The correct answer is:
As the sample size increases, the relative frequency of outcomes gets closer to the theoretical probability of the outcome.
Answer:
A Surveyed began playing soccer before the age of 10 is 68%
Step-by-step explanation:
Given the statement: A survey of professional soccer players found that 306 of the 450 players surveyed began playing soccer before the age of 10.
we have to find the percent of those surveyed began playing soccer before the age of 10.
Total number of soccer player = 450 players.
Number of player began playing soccer before age of 10 = 306
Percent states that it is a number or ratio expressed as a fraction of 100.
Percent =
= 68%.
Therefore, 68% of those surveyed began playing soccer before the age of 10.
