Answer: convenience sampling
Step-by-step explanation:
Convenience sampling is also referred to as opportunity sampling or accidental sampling and it occurs when a sample is selected from the population that is convenient and close to hand for the researcher. It's usually used during pilot testing.
Convenience sampling is such that the primary data source that are first available will be used for the research without any additional requirements being made.
77 is a multiple of 11, as i'm sure you know--the double numbers like 22 and 55, one of the factors are always 11.
77 is factored down into 11 and 7--which, when you add those, luckily equal 18.
(x + 11)(x + 7) is your factorization.
