A number that is not a whole number.
Draw the triangle and then use Pythagoras' theorem
distance =

= 19.70 (2dp)
Answer:

Step-by-step explanation:
Having the radius to be involved, the shape is a circle.
<u>Circumference formula </u>

Finding radius, formula will be reversed.


Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
