The time spent (in minutes) in reading newspaper for an adult per day can be approximated by a normal distribution with \mu μ =15 minutes and \sigma σ =3 minutes. if 200 adults are randomly selected, approximately how many of them will spend in reading newspaper per day between 12 minutes and 19.5 minutes

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
