G 7. In another study of these cities, customers were sampled by age. The totals for the cities and ages are given. a. What is the expected frequency in the Age 21-30 / Kingston cell? A. 12 Your answer is not correct. B. 6 This is the correct answer. C. 100 D. 18 b. What is the expected frequency in the Age 51-60 WINDSOR cell? A. 14 Your answer is correct. B. 35 C. 10 D. 12

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

the answer to your question is b.
