Answer:

Step-by-step explanation:
From C-A, it goes from y=1 to y=5, so that 4 units
From A-B, it goes from x = -1 to x = 4, that is 5 units
Now, to find distance from B to C, we need to use the distance formula:

Where the variables are the respective points of B and C,
B (4,5) & C(-1,1)
So x_1 =4, y_1=5, x_2=-1, y_2=1
Plugging into the formula we get:

Summing it all (perimeter is sum of 3 sides):
Distance = 
3rd answer choice is right.
 
        
             
        
        
        
Answer:
10.4  hope this help  ;)  77 x 10.4
Step-by-step explanation 
turn the 10.4 into .10 then multiply like this
77 x .10 =7.7
77+ 7.7 = 84.7
 
        
                    
             
        
        
        
Answer:
 Labrador retrievers
 Labrador retrievers
Step-by-step explanation:
We know that the mean  is:
 is:

and the standard deviation  is:
 is:

The probability that a randomly selected Labrador retriever weighs less than 65 pounds is:

We calculate the Z-score for X =65

So

Looking in the table for the standard normal distribution we have to:
 .
. 
Finally the amount N of Labrador retrievers that weigh less than 65 pounds is:
