Answer: b) statistic

Step-by-step explanation:

  • Population = A large groups of individuals sharing the same or similar characteristic by the point og study.
  • Sample  = It is a subset of population .
  • Parameter = It is measure of characteristic in population.
  • Statistic =  It is measure of characteristic in sample.

Suppose "35" cars start at a car race. In how many ways can the top 3 cars finish the​ race?
Thepotemich [5.8K]

Answer:

The  value  is   \left 35  } \atop }} \right. P_3  =  39270

Step-by-step explanation:

From the question we are told that

    The  total number of cars is  n  =  35

     The  number cars considered is  r = 3

Generally the number of different top three finishes possible for this race of 35 cars  is mathematically represented as

       \left n } \atop }} \right. P_r  =   \frac{n!}{(n - r) !}

       \left 35  } \atop }} \right. P_3  =   \frac{35! }{(35 - 3) !}

       \left 35  } \atop }} \right. P_3  =   \frac{35 *  34 *  33 *  32! }{32 !}

       \left 35  } \atop }} \right. P_3  =  39270

A shop has a sale that offers 20% off all prices.
NeTakaya
I think that the answer is 45% because the sale started off with a 20% discount, but at the end they added another 25% to the sales. So since the sale already started off with 20%, you add 20%+25% which equals 45%.
