In June an investor purchased 250 shares of Oracle (an information technology company) stock at $20 per share. In August she purchased an additional 400 shares at $27 per share. In November she purchased an additional 590 shares at $29 per share. What is the weighted mean price per share? (Round your answer to 2 decimal places. Omit the "$" sign in your response.)

Weighted mean = 26.54

Step-by-step explanation:

We are given the following in the question:

June:

250 shares of Oracle stock at $20 per share.

August:

400 shares at $27 per share.

November:

590 shares at $29 per share.

We have to calculate weighted mean price per share.

Formula:

The weighted mean share price is $26.54

∠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 answer is b.
