The average money spent on cigarettes is 2,190 a year. If a 16 year old starts smoking and quits at 30, how much money will be spent during that time?

30,660

Step-by-step explanation:

The first thing you want to do is find how long they've been smoking. To do this, you want to subtract 16 from 30 (30 - 16) to get a difference of 14 years. Now that you know how long they have been smoking, you can look at how much they spend. If they spend 2,190 a year, and they've been smoking for fourteen years, you can multiply 2,190 by 14 (2190 x 14) to get a sum of 30,660.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

if x decreases by 4 then y increases by 10
