Answer:
x=90° and y= 43°
Step-by-step explanation:In ∆ABC Applying
Angle sum property
47°+47°+2y=180°
y=43°
In ∆ABD Applying Angle sum property
x=90°
Answer:
participant bias
Step-by-step explanation:
Participant bias is sometimes called as subject bias. it is referred to as the tendency of a subject that forces them to act in an experiment. it is held because that they think researchers is looking up to them to act. it occurs only when the subject has detail knowledge about the study or project.

Answer:
AD = 5 units
Step-by-step explanation:
Given:
Perimeter = 18 units
BC = 4 units
CD = 3 units
Required:
Length of segment AD
Solution:
Perimeter = AB + BC + CD + AD
We can easily find AB,
AB = 6 units (distance from A to B)
Plug in the values
18 = 6 + 4 + 3 + AD
18 = 13 + AD
Subtract 13 from each side
18 - 13 = 13 + AD - 13
5 = AD
AD = 5 units
Answer:
The range of the given data set is 6.
Step-by-step explanation:
Range of the data set provides us with some basic information regarding spread of the data.
It is commonly used and quite easy to find.
First step is to arrange the values from the lowest to the highest.
It is already given arranged, so that will savd us some time.
Next step is simply subtracting the two values on the extremes, or, simply put, subtract the lowest from the highest value.
So, the range in this case would be 7-1=6.
The answer is c=-3 hope it helps
