Answer:
a) 9 km
b) 18 km
c) She runs at a constant speed of 9 km/h
Step-by-step explanation:
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.

Answer:
2
Step-by-step explanation:
The equation for a line is:
y=mx+b
Where m is the slope, b is the y-intercept, and x and y are the x and y coordinates.
The equation given to us is:
y=2x+3
Therefore 2 is the slope
