Step-by-step explanation:
Given that with a height of 63 in, Johnson was the shortest president of a particular club in the past century.
a) Positive difference between Johnson’s height and the mean=|63-66.5|=3.5 inches
b) No of std deviation the difference has =
c) Z score = no of std deviations from the mean = -2.692
d) Usual heights lie between -2 and 2. Hence Johnson’s height is unusual

Answer:
Step-by-step explanation:
In order to find the side mentioned (IJ), we need to use SOH CAH TOA.
SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:
Sin = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.
Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.
Our equation is now this:
Let's now solve for x.
Therefore, the length of IJ will be around 2.01.
Hope this helped!
