Question

Helpppp plzzz The frequency histogram shows the lengths of trails in a large park.

How many trails are less than 6 kilometers long or at least 24 kilometers long ?

Answer 1

13 trails

Explanation:

The histogram shows following numbers of trails:

• 0 - 6 km long - 5 trails;
• 6 - 12 km long - 9 trails;
• 12 - 18 km long - 7 trails;
• 18 - 24 km long - 3 trails;
• 24 - 30 km long - 4 trails;
• 30 - 36 km long - 1 trail;
• 36 - 42 km long - 3 trails.

So, there are 5 trails with length less than 6 km and 4 + 1 + 3 = 8 trails that are at least 24 km long.

In total, 5 + 8 = 13 trails
