Answer:
0.27
Step-by-step explanation:
The probability P that exactly two babies were born deaf can be gotten by the binomial distribution as

where n is the sample size (the number of babies  randomly surveyed), k is the number of success, i. e., the baby is deaf; and p is the probability of selecting a deaf baby = 2/1000 = 0.002. Therefore

Answer:
where is the shape of your question
 
        
                    
             
        
        
        
H(x) = 4x² - 8x - 60
    0 = 4x² - 8x - 60
    0 = 4(x²) - 4(2x) - 4(15)
    0 = 4(x² - 2x - 15)
    4               4
    0 = x² - 2x - 15
    0 = x² - 5x + 3x - 15
    0 = x(x) - x(5) + 3(x) - 3(5)
    0 = x(x - 5) + 3(x - 5)
    0 = (x + 3)(x - 5)
    0 = x + 3    or    0 = x - 5
  - 3        - 3        + 5      + 5
    3 = x       or       5 = x
        
             
        
        
        
Answer:
If you have a perpendicular shape, like a plus sign, usually what I was taught, right whole side of the "plus" sign are negative. The left side is positive. I think it's how you say it.
