Answer:
0
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
   = (-5--5)/ (9--8)
  = (-5+5)/(9+8)
  = 0/17
=0
The slope it 0
This is a horizontal line because the y value doesn't change.  If the y value doesn't change, the slope it zero.

Answer:
0.12
Step-by-step explanation:
Suppose there are 100 kids
60% have fever, so <em><u>what is 60% of 100?</u></em>
We convert percentage to decimal and multiply:
60/100 = 0.6
0.6 * 100 = 60 have fever
20% of the people having fever (60 of them) have sore throats, so,
<u><em>What is 20% of 60?</em></u>
We convert percentage to decimal and multiply:
20/100 = 0.2
0.2 * 60 = 12 have sore throat
So, how many people are there with fever AND sore throat, that is 12. We took initially there to be 100 people. Hence, the probability is:

 
        
             
        
        
        
Subtract 23 and 11 and you’ll get the answer
