Answer: i dunno what '.......' was suppose to mean but 11 + 15 + 19 + 83 = 128
Step-by-step explanation: b more specific dood -_-
In order to evaluate consistency in studies with more than one data collector, the<u> Inter-rater reliability </u>is used.
<h3>What is the Inter-rater reliability?</h3>
This is a measure in research that is used to test the data presented by different data collectors, for consistency.
It essentially checks the extent to which the data collected from the different sources agree with each other.

B. y=12x+7
Explanation
The slope is 12; slope=m
The yint is 7; yint=b
The equation of a line is set up as so
y=mx+b
Now we just need to replace the variables with the numbers
y=12x+7

Answer:
The answer to your question is below
Step-by-step explanation:
Data
Equation 25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse

3.- Find a, b and c
a² = 64 a = 8
b² = 25 b = 5
-Calculate c with the Pythagorean theorem
a² = b² + c²
-Solve for c
c² = a² - b²
-Substitution
c² = 8² - 5²
-Simplification
c² = 64 - 25
c² = 39
-Result
c = √13
4.- Find the center
C = (0, 0)
5.- Find the vertices
V1 = (-8, 0) V2 = (8, 0)
6.- Find the foci
F1 = (-√13, 0) F2 = (√13, 0)
