Answer:
x³ +9x² +27x +27
Step-by-step explanation:
Put x where 'a' is, and put 3 where 'b' is in the given pattern, then simplify.
(x +3)³ = x³ +3x²(3) +3x(3²) +3³
= x³ +9x² +27x +27
Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.
Step-by-step explanation:
We know that the level of significance ( denoted as
) is generally the probability of rejecting the null hypothesis when it is true.
Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.
i.e. The probability of rejecting the null hypothesis when it is true= 0.05
In percent : 
Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.
