Answer: 17.69 miles
Step-by-step explanation:
Activity time (hours) :
Activity - - - - - - - - - - - - - time (hours)
Hiking - - - - - - - - - - - - - - - - - - - - 3
Mountain biking - - - - - - - - - - - 1.45
Horseback riding - - - - - - - - - - 1.2
Cross-country skiing - - - - - - - - 0.75
Average speed = 12.2 miles per hour.
How many miles did Brian bike?
Recall;
Speed = distance ÷ time
Distance = speed × time
Speed = 12.2 mi/hr
biking time = 1.45 hours
Distance (mountain biking) = 12.2 × 1.45 = 17.69 miles
Answer:
a) Exponential smoothing provides smoothed values for all the time period observed while moving average doesn't provide smoothed values for the first and last set of periods.
Step-by-step explanation:
Best difference between exponential smoothing and moving average is option a . Where exponential smoothing is a technique for time series data using exponential function. Exponential are used to assign exponentially decreasing weight .It provide smoothed values over time.
while average dose not provide smoothed values.It doesn't a fixed period but it takes all data series.
Answer: n= t+2/3
Step-by-step explanation: 3n-2+2=t+2
Step 1.) 3n= t+2
Step 2.) 3n/3 = t/3 + 2/3
Step 3.) n= t+2/3
