The cumulative frequency of the data given is shown in the image attached below.

<h3>How to Find the Cumulative Frequency?</h3>

To find the cumulative frequency of each data with a given class interval or data point, and their respective frequency, simply add each frequency from the frequency distribution to the sum of the previous frequency.

The cumulative frequency of the data in the table given would be calculated as shown below:

15 - 18 ---> 5 + 0 = 5

19 - 22 ---> 10 + 5 = 15

23 - 26 ---> 7 + 15 = 22

27 - 30 ---> 3 + 22 = 25

31 - 34 ---> 3 + 25 = 28

35 - 38 ---> 2 + 28 = 30

Thus, the cumulative frequency of the data given is shown in the image attached below.

goldenfox [79]

Answer:

The scale used is 1: 10,000 cm.

Step-by-step explanation:

Given that the length of a pool 2 km long is represented on a map with a length of 20cm, to determine what is the map scale used the following calculation must be performed:

2 km = 2,000 m

1m = 100cm

2,000 x 100 = 200,000

20: 200,000

10: 100,000

1: 10,000

Thus, the scale used is 1: 10,000 cm.
