It might be 9 if it's not 6 ...but I can't see how it wouldn't be 6?
        
                    
             
        
        
        
Answer:
<h3>             C.    y + 7 = -7(x - 3)</h3>
Step-by-step explanation:
The equation of a line is:
                           y - y₀ = m(x - x₀)
where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through
The product of slopes of two perpendicular lines is  -1
so if given lines slope is ¹/₇ them:
      ¹/₇·m = -1
         m = -7
(3, -7)     ⇒    x₀ = 3,  y₀ = -7 
Therefore:
                y - (-7) = -7(x - 3)
                 <u> </u><u>y + 7 = -7(x - 3) </u>
 
        
             
        
        
        
Answer:
The probability is  0.003
Step-by-step explanation:
We know that the average  is:
 is:

The standard deviation  is:
 is:

The Z-score is:

We seek to find

For P(x>800) The Z-score is:



The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15% 
So

For P(x<200) The Z-score is:



The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15% 
So

Therefore
