Answer:
<u>The variance of the sample data is 134.8339 kg²</u>
Step-by-step explanation:
Let's recall that the Standard deviation of a sample or population is the square root of the Variance, therefore:
Standard deviation = √Variance
Standard deviation² = (√Variance)²
Standard deviation² = Variance
Replacing with the value we have:
11.6118 * 11.6118 = Variance
Variance = 134.8339 kg²
<u>The variance of the sample data is 134.8339 kg²</u>
Answer:

It would be 3/10 because you have to create a common denominator. That would be 10. 3x2=6 and 5x2=10, so 3/5 would become 6/10, which is equivalent. If you kept the denominators the same and subtracted the numerators, you would get 3/10.
(125 km) x (1mile / 1.609344 km) = <em>77.6714 miles</em> (rounded)
