Normal room temperature (at least for our rooms) is 75-80º. Normal body temperature is about 98.6º. What does that tell you?

statistics
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

math
a. Mean is most influenced by deviant scores, since it acts as a fulcrum (balance point) for the distribution — median. b. Only a nominal scale — mode. http://drdavespsychologypage.intuitwebsites.com/Two___Two_____four.pdf c. If normal distribution — mean. ...

Math
Since you have -5x on one side, to combine it with the 4x on the other side, you add 5x to both sides. This cancels out the -5x on one side and adds 5x to 4x on the other. The same principle works with the 15.

Math
Combine terms by adding 5x and subtracting 15 from both sides. -11 = 9x Divide both sides by 9. -11/9 = x

statistics
In a normal distribution, mean = median = mode.
