Answer:
4 units
Step-by-step explanation:
we know that
The <u><em>Intersecting Chord Theorem</em></u> states that: When two chords intersect each other inside a circle, then the products of their segments are equal.
do
In this problem

substitute the given values

solve for x

therefore
The length of segment AY is 4 units
Answer:
The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin error.
Step-by-step explanation:
Margin of Error is a statistical measure of random sampling error insurvey results.
Level of confidence reflects percentage range around sample mean, that can be expected to contain population actual parameter.
High level of confidence means larger range band of confidence interval, supposed to contain the population parameter. This further implies high expected variation between sample statistic & actual parameter i.e Margin Error increases.
