Answer:

Approximate difference between 1 mile and 2 km in meters = 390.66meters

Step-by-step explanation:

I mile =1609.34meters

also 1000m = 1km

therefore 2km = 2 x 1000= 2000m

Approximate difference = 2000m - 1609.34m

=390.66 meters.

 Approximate difference between 1 mile and 2 km in meters = 390.66meters

Using the data in the table, use the exponential smoothing method with alpha=0.5 and a February forecast of 500 to forecast
Sever21 [200]

Answer:

Step-by-step explanation:

The formula to calculate the forecast could be determine by using the exponential smoothing method :

Ft = F(t-1) +  \alpha [A(t-1) - F(t-1)]

Where ,Ft is the Forecast for period t

F(t-1) is the Forecast for the period previous to t

A(t-1) is the Actual demand for the period previous to t

\alpha = Smoothing constant

To get the forecast for may and june   the above formula with \alpha =0.5 and april forecast of 500 will be used

For march

=500+0.5(520-500)\\\\=500+0.5\times20\\\\=500+10\\\\=510

For April

=510+0.5(535-510)\\\\=510+0.5\times25\\\\=510+12.5\\\\=522.5

For May

=522.5+0.5(550-5225)\\\\=522.5+0.5\times27.5\\\\=522.5+13.75\\\\=536.25

So forecast for May = 536.25

Kamila [148]

Answer:

6/35 miles per hour

Step-by-step explanation:

To find the unit rate, put distance over time

distance = 1/7 miles

time = 5/6 of an hour

miles/hours

(1/7)/(5/6)

(1/7)*(6/5)

6/35 miles per hour
