Find range ,median mode and mean of the following numbers -19,-11,-19,-18,-13,-19,-18,-11.0, 11,12

Range= 31 because 12- -19 = 31 you subtract the lowest with the highest.
Mean= 8.3
Mode = -19 because you mostly see -19 there’s 3 -19 . :)))
Answer:
12 positive
Step-by-step explanation:
(7)^2 +
2nd power means squaring a number and since you need to do that first, it goes in brackets.
Answer:
-19,6830x^26
Step-by-step explanation:
The nth term of a geometric sequence is expressed as;
Tn -= ar^n-1
a is the first term
is the number of terms
r is the common ratio
Given
a = -10x^8
r = 30x^10/-10x^8 = -3x^2
n = 10
Substitute
a10 = (-10x^8)(-3x^2)^10-1
a10 = (-10x^8)(-3x^2)^9
a10 = -10x^8)(19,683)x^18
a10 = -19,6830x^26
Hence the tenth term is -19,6830x^26
