Normal Distribution multiple-choice problem I need help answering!! The distribution of weights of apples at a local supermarket is normally distributed with a mean of 0.75 lbs and standard deviation of 0.12 lbs.
Approximately 98% of the apples weigh at least...
A) 0.5034 lbs
B) 0.9966 lbs
C) 0.6496 lbs
D) 0.85038 lbs
E) 0.5940 lbs

, and

for

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

, and for

d is the only accurate one
