For a certain experiment you have 8 subjects, of which 4 are female and 4 are male. The
names of the subjects are listed below.
Males: Allen, Brown, Chevalier, Dugas F emales Jones, King, Lewis, Moore
There are to be two treatment groups, A and B. If a randomized block design is used,
with the subjects blocked by their gender, which of the following is not a possible group
of subjects for treatment group A?
a. Allen, Brown, King, Lewis
b. Brown, Chevalier, Lewis, Moore
c. Allen, Brown, Dugas, King
d. Allen, Brown, Jones, Moore
e. Allen, Chevalier, Jones, King

a

step-by-step explanation:

(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
