Irrational numbers cannot be expressed as a fraction for any integers and they have decimal expansions
Calculate the z-score for the given data points in the item using the equation,
z-score = (x - μ) / σ
where x is the data point, μ is the mean, and σ is the standard deviation.
Substituting,
(47.7) z-score = (47.7 - 52.5)/2.4 = -2
This translates to a percentile of 2.28%.
(54.9) z-score = (54.9 - 52.5)/2.4 = 1
This translates to a percentile of 84.13%.
Then, subtract the calculate percentiles to give us the final answer of <em>81.85%.</em>
Thus, 81.85% of the Siberian Husky sled dogs are expected to weigh between 47.7 and 54.9 lbs.

Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.
To find the circumference of the circle we must know this formula first :
Where
- r is the radius of the circle.
- We'll take the value of π as 3.14
Now substituting the values in the formula :
Therefore,
- The circumference of the circle is 50.24 inches
