Let X denote the proportion of allotted time that a randomly selected student spends working on a certain aptitude test. Suppose the pdf of X is f(x; u) 5 5 (u 1 1)xu 0 # x # 1 0 otherwise where 21 , u. A random sample of ten students yields data x1 5 .92, x2 5 .79, x3 5 .90, x4 5 .65, x5 5 .86, x6 5 .47, x7 5 .73, x8 5 .97, x9 5 .94, x10 5 .77. a. Use the method of moments to obtain an estimator of u, and then compute the estimate for this data. b. Obtain the maximum likelihood estimator of u, and then compute the estimate for the given data.

b) the dogs need to shift their focus to human scent.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
