For which of the following displays of data is it not possible to find the mean?(Expert and Ace only please)

pantera1 [17]

You will not be able to find the mean from a histogram. The reason is that histograms are special bar graphs that graph data that fall into a range/interval. For example, you would create bars based on what data might fall into 0-9, 10-19, 20-29, 30-39, etc...

With intervals, we do not know the exact data points. They just fall into a range.

The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean

Marizza181 [45]

Answer:

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.
