Acertain flight arrives on time 85 percent of the time. suppose 127 flights are randomly selected. use the normal approximation to the binomial to approximate the probability that (a) exactly 101 flights are on time. (b) at least 101 flights are on time. (c) fewer than 102 flights are on time. (d) between 102 and 115, inclusive are on time.

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

i those same problems in math and dont know how to do them
