Answer:
   y = one-half x + three-fourths
Step-by-step explanation:
The 2-point form of the equation of a line can be used for starters.
   y = (y2 -y1)/(x2 -x1)(x -x1) +y1
   y = (11/12 -19/20)/(1/3 -2/5)(x -2/5) +19/20 . . . . fill in given values
   y = ((55 -57)/60)/((5 -6)/15)(x -8/20) +19/20 . . simplify a little
   y = (-1/30)/(-2/30)(x -8/20) +19/20 . . . . . . . . . . and a little more ...
   y = 1/2x -4/20 +19/20
   y = 1/2x +15/20
   y = 1/2x +3/4 . . . . line in slope-intercept form
 
        
                    
             
        
        
        
ANSWER

EXPLANATION
Use the Pythagoras Theorem to obtain,

This implies that,


Take the positive square root of both sides to get,


 
        
                    
             
        
        
        
Answer:
Type I error.
Step-by-step explanation:
Let's remember the definition of Type I error and Type II error:
A type I error is the rejection of a true null hypothesis, this means that we would get a "false positive" with this error. 
A type II error is the non rejection of a not true null hypothesis, this error would give us a "false negative".
In this problem, we are told that the mean match score to identify a suspect is 80. However, the test shows that the mean match score is more than 80 when the person doesn't have a fingerprint match (and therefore the person would not be a suspect). Therefore, this person would appear as a suspect when he/she really isn't one. This means that the test is giving a "false positive". Thus, this is a type I error.
 
        
             
        
        
        
Answer:
10  > 2.01
Step-by-step explanation:
Since 2.01 has a point of decimal after the # 2, it is known is a 2 so 10 should be greater than the 2.
