X is a 90 degree angle so x equals half of 90 which is 45
X= 45
Since x is 45 the other angle on the other side is 45
Every triangle equals 180 so you take 45+45 to get 90 and subtract that from 180 and get 90
Y= 90

The record that represents an outlier in this data set is John's weight.
<h3>What is an outlier?</h3>
An outlier is a data point that differs significantly from other observations.

Explanation: Note that
Let

=
z-score for I.

=
z-score for x.
The formula for z-score is given by

So,


Based on inequality in (1),
So,

Since

and

are z-scores and the level of nitrogen oxides are normally distributed, using normal distribution calculator (or table),
