Using the Fundamental Counting Theorem, it is found that:
The 2 people can arrange themselves in 40 ways.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with 
ways to be done, each thing independent of the other, the number of ways they can be done is:
With one people in the aisle and one in the normal seats, the parameters are:
n1 = 4, n2 = 7
With both in the aisle, the parameters is:
n1 = 4, n2 = 3
Hence the number of ways is:
N = 4 x 7 + 4 x 3 = 28 + 12 = 40.

Answer:
b. the association is consistent when results are repeated in studies in different settings using different methods
Step-by-step explanation:
-In statistics and research, internal consistency is typically a measure based on the correlations between different items on the same test (or the same subscale on a larger test).
-It measures whether several items that propose to measure the same general construct produce similar scores.
Answer:
x=21
Step-by-step explanation:
Let's solve your equation step-by-step.
3x+5+5x+7=180
Step 1: Simplify both sides of the equation.
3x+5+5x+7=180
(3x+5x)+(5+7)=180(Combine Like Terms)
8x+12=180
8x+12=180
Step 2: Subtract 12 from both sides.
8x+12−12=180−12
8x=168
Step 3: Divide both sides by 8.
8x
/8
=
168
/8
x=21
