The weight of 100 earth worms is recorded in a grouped frequency table. The cumulative frequency is calculated and displayed in the table below.
What is the value of q?

q = 80

Step-by-step explanation:

Here, we want to get the value of w

Mathematically, we can obtain the cumulative frequency from the frequency tab

To do this, we have to sum up the frequencies at each point to get the cumulative at each point

We add the frequency above to the frequency below to get the value of the cumulative frequency at that point

We have it that;

we start with 10: as seen on the frequency column

then we proceed;

10 + 20 = 30

30 + 30 = 60

60 + 20 = 80

80 + 10 = 90

90 + 10 = 100

As we can see here, the value of q is 80
