This is my answer! I solve it by myself, check it out!!!! Sorry for late
i dont know the way you wan me to solve this but i got 1−2cos(t)sin(t)=1−2sin(t)cos(t)
The answer is 6 People. You make the two equations first 12.99x and 8.99x+20. And then make them equal each other 12.99x = 8.99x+20. Then you use algebra to solve for the x and you get an answer of 5. That is the number of people that would cause the two prices to break even (be the same price). So in order for the group rate to be the better deal you need 6 people to attend.
Answer:
Step-by-step explanation:
A Parameter is a value that represents a property of a population. This could be the population mean.
A statistic is a value that represents a property of a sample. This could be the sample mean.
In the given scenario, the population is the entire 14 teams. This means that the percentage given is a value representing a property of the population. Therefore, the correct answer is
C. Parameter, because the data set of all 14 teams is a population.
