This means that everybody answered the same number of items. This means that every data value is equal to the mean. This outcome permits us to say that the sample standard deviation of a data set is zero if and only if all of its values are same or identical.

Answer:
6.3 x 10°
Step-by-step explanation:
6.3 can be written as 6.3 x 1
recall that anything to the power of zero = 1
hence 10° = 1 substitute this back into the expression above to get:
6.3
= 6.3 x 1
= 6.3 x 10°
Answer:
x = 10
Step-by-step explanation:
1/10(x + 130) = -2(3 - x)
x + 130 = -20(3-x)
x + 130 = -60 + 20x
x - 20x = -60 - 130
-19x = -190
x = 10
