When the bureau of labor statistics conducts a survey, it begins by partitioning the united states adult population into 2,007 groups called primary sampling units. assume that these primary sampling units all contain the same number of adults. if you randomly select one adult from each primary sampling unit, is the result a simple random sample?

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

5 + 8 +7 + 4 + 0 +1 = 25
