The domain of the square root, the 4th root, the 6th root, etc., is [0, infinity); in other words, the input to these functions cannot be negative.
Answer:
If it is a quadratic equation then it's zeroes are alpha and beta. Sum of zeroes is -b/a. So alpha plus beta is -b divided by a.
Step-by-step explanation:
Answer:
C. The degree of dependence among the observation is negligible.
Step-by-step explanation:
The conditions for performing a t-procedure when constructing a t-interval are;
1) The samples observation should be independent of each other
2) The use of a random sample or experiment for the procedure
3) Ensure the normality of the data of the dependent variable
Given that surveys usually involve sampling without replacement from a population which is finite can not be taken as independent Bernoulli trials however, it is allowable to still consider samples independent when they are less than 10% the size of population
Therefore, the reason for the condition is to ensure that the population to sample size ratio is large enough and that the degree of dependence among the observation is negligible.
