Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
It has two extra zeroes because any number times one is always itself, then you would add two extra zeroes to the end. For example: 100 x 360= 36000, or 36x100=3600.
The circumference of a circle of given diameter d is pi*d.
Thus, if the diameter is d = 6 cm, the circumference of the circle is (6 cm)*pi.
