Researchers conducted a study to examine the association of clinical factors at birth with sudden infant death syndrome (SIDS) (Platt et al., 2000). The researchers randomly sampled the medical records of infants who died of SIDS from a large database. The study found 63 infants who had a premature birth in 323 medical records, which produced a 95% confidence interval of 0.20±0.04 . What can the researchers conclude about this confidence interval?

step-by-step explanation:

add the time and multiply by 2

the answer is 48m^2!

step-by-step explanation:

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
