Which formula can be used to describe the sequence?
-2/3, -4, -24, -144
A. f(x)=6[-2/3]^x-1
B. f(x)=-6[2/3]^x-1
C. f(x)=-2/3[6]^x-1
D. f(x)=2/3[-6]^x-1

d? maybe

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
