Determine whether the statement below is true or false. If it is false, rewrite it as a true statement. The number of different ordered arrangements of n distinct objects is n!. Choose the correct answer below. O A. The statement is true. O B. The statement is false. A true statement is, "The number of different unordered arrangements of n distinct objects is n!." O C. The statement is false. A true statement is, "The number of different ordered arrangements of n distinct objects is n." O D. The statement is false. A true statement is, "The number of different ordered arrangements of n distinct objects is (n- 1)!."

A forecaster used the regression equation Qt = a + bt+c₁D₁ + C2 D2 + c3 D3 and quarterly sales data for 2004/-2021/V(t = 1, ..., 64) for an appliance manufacturer to obtain the results shown below. Q is quarterly sales, and D₁, D2 and D3 are dummy variables for quarters I, II, and III.

Suppose that a certain population has a growth rate that varies with time and that this population satisfies the differential equation dy dt NOTE: Round your answers to two decimal places. = (0.5+ sint) / 5 a) If y(0) = 1, find (or estimate) the time 7 at which the population has doubled. Choose other initial conditions and determine whether the doubling time 7 depends on the initial population. The doubling time is 7 = The doubling time Choose one depend on the initial population. b) Suppose that the growth rate is replaced by its average value Determine the doubling time 7 in this case. In this case, T= 1 10 c) Suppose that the term sint in the differential equation is replaced by sin(2πt); that is, the variation in the growth rate has a substantially higher frequency. What effect does this have on the doubling time T? In this case, T =
