Solution:
Given:
A table representing an exponential function.
The x-values represent the terms, while the y-values represent the numbers.
The common ratio is gotten from the numbers (y-values).
The formula for common ratio is given by;

Therefore, the common ratio is 3.
X = 38
2x is equal to the angle next to the x + 66 angle because ℓ1 ∥ ℓ2 is parallel so:
2x + x + 66 = 180 -- combine like terms
3x + 66 = 180 -- subtract 66 from both sides
3x = 114 -- divide by 3 on both side
x = 38

Answer:
Null hypothesis: the variance in hours of usage for talking is not greater than the the variance in hours of usage for internet.
: 
Alternative hypothesis: the variance in hours of usage for talking is greater than the the variance in hours of usage for internet.



Step-by-step explanation:
Let
and
be the two variables that represents the battery life in hours for talking usage and battery life in hours for internet usage respectively.
The hypothesis can be formulated as:
Null hypothesis: the variance in hours of usage for talking is not greater than the the variance in hours of usage for internet.
: 
Alternative hypothesis: the variance in hours of usage for talking is greater than the the variance in hours of usage for internet.

The standard deviation for the battery usage for talking is :

The standard deviation Is:




The standard deviation for the battery life usage for the internet is :




Thus; the standard deviation is:
