We can set up an equation.
.05 * 2^(n-1)
n being the nth term in the sequence
Plug in and solve.
.05 * 2^(20-1)
.05 * 2^19
.05 * 524, 288
The 20th term would be 262, 144.
By directors cut, if it’s how much he took away its 198 minutes. if it’s how much the video was, its 162.
The answer is zero.
If any of the pairs of lines were parallel, there would be some same-side interior angles or such that would be supplementary. However, since the lines are not parallel lines crossed by a transversal, the only ones guaranteed to be supplementary to angle 7 are the ones adjacent to it that form a linear pair.
Answer:
Test: 
< 20 with normal distⁿ
Hypothesis test:
H0: 
20 (Null Hypothesis, H₀ : = 20 is also correct)
H1: < 20 (Alternative Hypothesis, also called H₁)
This is lower tailed test.
Since sample is large, sample standard deviation can be taken as an approximation of population standard deviation.
x = 19.3
= 11.1
n = 444
significance level, 
= 0.05 (If no value is given, we take level of 0.05)
Test statistic 
= - 1.33
