Step-by-step explanation:
Measure of spread is used in describing the variability in a sample.
Examples of measure of spread are: Mean, Median and Mode.
A measure of spread helps in giving an idea of how well the mean, or mode, or median, whichever of the three measure of spreads we use, represents the data under consideration. If the spread of values in the data set is large, that means there a lot of variation between the values of the data set. It is always better to have a small spread.
There are 3 terms in this expression. You can determine this answer by knowing that terms are either a single number or variable or numbers and variables multiplied together. Here's a picture example below:

Answer:
a. -6
b. +6
c. -6
Step-by-step explanation:
minus times plus times plus = -
minus times minus times plus = +
minus times minus times minus = -
1 times 2 times 3 = 6
so:
-1 times 2 times 3 = -6
-1 times -2 times 3 = +6
-1 times -2 times -3 = -6
Exponent rule : a^-b = 1 / (a^b)
1/9 ^-3 =
1 / (1/9^3) =
1 / (1^3) /(9^3) =
1 / (1/729) =
1 * 729/1 =
729
ur answer is B
