Answer:
+1.12 and -1.12
Step-by-step explanation:
Let the two z scores be .
Since the two Z-scores that separate the middle 73.72% on the Standard Normal Curve, this can be represented by the equation:
From the z table of the normal distribution, z₁ = 1.12. That is a z score of 1.12 gives 0.8686.
The two z scores are +1.12 and -1.12 = ± 1.12
The exact circumference of the circle is
The approximate circumference of the circle is
Explanation:
The diameter of the circle is
Now, we shall find the circumference of the circle.
The formula to determine the circumference of the circle is given by
Where C is the circumference , is 3.14 and
is the diameter of the circle.
The exact circumference of the circle is given by
Multiply both numerator and denominator by 100, we get,
Converting into mixed fraction, we get,
Thus, the exact circumference of the circle is
The approximate value of the circumference can be determined by dividing the value
Thus, the approximate circumference of the circle is
