12th grade statistic A case control study was performed by DuPont chemical corporation in 2018 looking back 20 years at residents from Parkersburg, West Virginia, where the company has been found guilty of dumping chemicals in the Ohio River. They compared groups of people who contracted Non-Hodgkin's lymphoma in unusually high rates from this region to people who didn’t contract the disease from the same area in hopes to prove that exposure to those chemicals isn’t the cause for the unusually high rates of this cancer. A detailed report was provided to the public with the methodology showing a large sample size and solid statistical procedures being followed. Provide one reason to trust the results of the study and one reason to be skeptical of the results.

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

(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 on e2020 was d.
