The proportion of waiting times in the sample that are greater than or equal to 18 minutes is 0.16.
<h3>What is a histogram?</h3>
A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. 
Number of people whose wait time was equal or greater than 18 minutes / total number of people = (2 + 2) / (6 + 7 + 8 + 2 + 2) 
4/25 = 0.16

Answer:
1st blank=
2nd blank=
3rd blank= 
3*27=81
so 1* =81
=81
hence  =81
=81
9*  = 81
= 81
 =9
=9
27* =81
=81
 =3
=3
Thus solved.

Answer:
so she saved 82 cents in the interest the month after
Step-by-step explanation:
case 1: payment is $75
interest on 2000 = 0.125/12×2000 = $20.83
so the actual repayment on the balance = (75-20.83) = $54.17
therefore,balance =$(2000-54.7)=$1945.83
interest in the next month = $20.27
case 2: payment is $100
interest on 2000 is still $20.83
repayment = $79.73
balance = $1920.27
interest in the next month = 20.01
so she saved 82 cents in the interest the month after
