The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 258.6 and a standard deviation of 69.4. (All units are 1000 cells/muL.) Using the empirical rule, find each approximate percentage below. a.
What is the approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 119.8 and 397.4?
b.
What is the approximate percentage of women with platelet counts between 50.4 and 466.8?

answer: i believe it’s 245.04

step-by-step explanation:

∠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.

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
