You have found the following ages (in years) of all 5 zebras at your local zoo: 8, 11, 17, 7, 19? What is the standard deviation? Round your answers to the nearest tenth.

And the can be founded with this formula:

And rounded to the nearest tenth we got

Step-by-step explanation:

For this case we have the following data given:

8, 11, 17, 7, 19

The first step is calculate the sample mean with this formula:

And replacing we got:

And the deviation can be founded with this formula:

And replacing we got:

And rounded to the nearest tenth we got

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
