You and 8 friends went out to dinner, and they've asked you to divide the $177 bill. If you
want to tip the waiter 20%, how much does each person owe?

26.55

Step-by-step explanation:

Take 177 and multiply that to .20(20%) because you change that percentage into a decimal by changing the sign to a decimal and always moving it over two places and should get 35.4 and then add that to $177. After you add it, you should get $212.40 and then divide that between the eight of them and get 26.55.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
