The gypsy moth is a serious threat to oak and aspen trees. a state agriculture department places traps throughout the state to detect the moths. when traps are checked periodically, the mean number of moths per trap is only 1.2, but some traps have several moths. the distribution of moth counts in traps is strongly right skewed, with standard deviation 1.4. a random sample of 60 traps has x = 1 and s = 2.4.

let x = the number of moths in a randomly selectd trap

(a) for the population distribution, what is the

? =
deviation? =

(b) for the distribution of the sample data, what is the

? =
deviation? =

(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
