1. A hobbyist family is making PPE (personal protective equipment) to donate to local health care workers. Let • T1 ∼ U(1, 4) be the amount of time (in hours) to 3D print a face mask and • T2 be an exponentially distributed random variable with an average of 3 hours to represent the time (in hours) to cut out and sew a suit. Describe the distribution of time to complete construction of one suit-and-mask outfit by computing the mean, median, and standard deviation of the sum T1 + T2 assuming independence between T1 and T2. (Hint: there is only one input variable—time—so there is no need for double integrals.)

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.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
