Based on data collected over several sessions, a statistically minded trainer of office typists modeled the linear relationship between the number of hours of training a typist receives and the typist's speed (in words per minute) with the equation ModifyingAbove speed with caret equals 10.9 plus 5.7 (hour ). After some training, one of the typists was told that the speed he attained had a residual of 4.1 words per minute. How should he interpret this?

answer are

step-by-step explanation:

50- 250 is correct i did that one too

step-by-step explanation:

i have no clue what you just said. write a question in english?

(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
