In a previous​ year, ​% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of females aged 15 and older and finds that are living alone. Is there sufficient evidence at the level of significance to conclude the proportion has​ changed?

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Can you me find the slope! (30 points)
