Answer:
d) 1
Step-by-step explanation:
The variance of standard normal distribution is simply put as 1.
If you take it a bit further, even though not asked, the mean of a standard normal distribution is 0.
Therefore, the conclusion is that, the variance of a standard normal distribution is 1, while the mean of the same standard normal distribution is 0
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
given p² + 4p - 12 = 0 ← in standard form
with a = 1, b = 4, c = - 12, then the discriminant
Δ = b² - 4ac
  = 4² - (4 × 1 × - 12) = 16 - (- 48) = 16 + 48 = 64 → D
