Something to keep in mind for a question like so it that all interior angles in a triangle equal 180 degrees, one more thing to note is that a straight is supplementary meaning it adds up to 180 so now let’s begin math!
So 180 - 147 = 33 So Now we can find To do this we need to remember that interior angles of the triangle always equals 180 With that we will add 40 + 33 = 73 Now to find the missing angle we will subtract our sum to 180 to get the answer 180 - 73 = 107
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
Note: Shape does not change.</span>
