Lia’s track coach recorded the number of laps run by her team members as shown in the table below. She also made a box plot to show the same data. 15, 20, 24, 40, 30, 28, 32, 52, 45, 33, 18, 38. What is the interquartile range of the data?

IQR = 17

Step-by-step explanation:

Arrange the numbers in order to least to greatest then split the numbers in half. Next find the median for the lower half and the upper half. The median of the lower half is 22 which will be Q1 and the median of the upper half is 39 which will be Q3. Finally subtract 22 (Q1) from 39 (Q3) and that equals the IQR of 17.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
