Let X be the proportion of allotted time that a randomly selected student spends working on a certain aptitude test. Suppose the pdf of X is (x; theta) = (1 + theta)x , 0 ≤ x ≤ 1 for θ > −1. A random sample of 10 students yields data: x1 = 0.92, x2 = 0.79, x3 = 0.90, x4 = 0.65, x5 = 0.86, x6 = 0.47, x7 = 0.73, x8 = 0.97, x9 = 0.94, x10 = 0.77. (a) Use the MOM to obtain an estimator of θ; compute an estimate for the given data. (b) Obtain the MLE of θ and then compute an estimate for the given data

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.
