X=invested at 10%12000-x=invested at 15% .10x+ (.15)(12000-x)=1440 ;; 12% of the total amount is 12% of $12000. .10x + 1800-.15x=1440
-0.05x=-360x=7200 12000-x=4800 $7200 at 10%=$720$4800 at 15%=$720 That is $12000 earning $1440, and that is 12%

Answer:

Runner 1

Step-by-step explanation:

Runner 1's speed is the slope of the line = (20-0)/(2-0) = 10

Runner 2's speed is the slope of the line = 8.5 (the coefficient of t)

Runner 3's speed is slope = (36-18)/(4-2) = 9

The fastest pace, therefore is of runner 1, because 10>9 AND 10>8.5

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
