Thes first rule is correct. 

Another way of doing it is:

Sum the digits of the number. If the result is divisible into nine, then the original number itself will also be.

Example:

18 = 1+8 = 9. 9 is divisible into 9.

27 = 2+7 = 9. 9 is divisible into 9.

Wish you luck!

Explain when the median of a data set is a better<br> measure of center than the mean.
Delvig [45]

Answer:

The median of a data set is better when you have a term or terms that are not close to the other terms

Step-by-step explanation:

For example:

Say you have the data set

1, 15, 17, 18, 22, 84

The median of these terms would be 17.5

       (it is the exact center of the data group)

17 + 18 = 35

35/2 = 17.5

The mean of these terms would be 26.17  

    (this number is not close to the center because the numbers 1 and 84

      are not close enough to the other terms)

1 + 15 + 17 + 18 + 22 + 84 = 157

157/6 = 26.17

Eddi Din [679]

Answer:

92°

Step-by-step explanation:

We can say that the angle that is of x degrees is an inscribed angle because its vertex is on the circle and its sides are made up of rays. When you have an inscribes angle, it measures exactly half the angle it intercepts. In this case that angle is 184°. So, because of this we can say:

x = 184° / 2

x = 92°
