Matilda has about 6 missing cases on her index of voting interest out of 1500 respondents. the best strategy for handling these missing case would be to:

The best strategy is to exclude the 6 missing cases from the computation and analysis of the index.

Step-by-step explanation:

Generally, indexing is commonly used as a statistical tool for grouping specific segments or sets of data. In this case, Matilda is trying to conduct the indexing of the voting interests of about 1500 respondents. However, she discovered that there are 6 missing cases on her index of voting interest. In order to ensure effective analysis, it is paramount to separate missing cases from the other respondents. Therefore, the best strategy is to exclude the 6 missing cases from the computation and analysis of the index.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
