As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others
8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^
We can rewrite (z ≤ −1.75) in order to 4%.
We have given that (z ≤ −1.75).
We have to use the Normal Distribution is symmetrical
<h3>What is the Normal Distribution is symmetrical?</h3>The normal distribution is symmetric and has a skewness of zero.
That is nothing but the 4%
