The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.934 g and a standard deviation of 0.295 g. the company that produces these cigarettes claims that it has now reduced the amount of nicotine. the supporting evidence consists of a sample of 40 cigarettes with a mean nicotine amount of 0.845 g. assuming that the given mean and standard deviation have not changed, find the probability of randomly selecting 40 cigarettes with a mean of 0.845 g or less. p(m < 0.845 g) = enter your answer rounded to 3 decimal places. based on the result above, is it valid to claim that the actual mean amount of nicotine may lower than 0.934 g

, 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

tip $2.90

total $17.40

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

i suppose it should be (y=2x-5)
