To help plan its nursing staff schedule, a large hospital uses simple exponential smoothing to forecast the daily number of hosp

Morgarella [4.7K]

Answer:386

Step-by-step explanation:

We have given

Smoothing parameter $\left ( \alpha \right )=0.56$

Forecasted demand $\left ( F_t\right )=385$

Actual demand $\left ( D_t\right )=386$

And Forecast is given by

$F_{t+1}=\alpha D_t+\left ( 1-\alpha \right )F_t$

$F_{t+1}=0.56\cdot 386+\left ( 1-0.56\right )385=385.56\approx 386$

$F_{t+2}=0.56\cdot 386+\left ( 1-0.56\right )385.56=385.806\approx 386$

$F_{t+3}=0.56\cdot 386+\left ( 1-0.56\right )385.806=385.914\approx 386$

$F_{t+4}=0.56\cdot 386+\left ( 1-0.56\right )385.914=385.962\approx 386$

I need hellllppp plsssss

Answer:

$a_7=-15$

Step-by-step explanation:

$a_n$ is given as the nth term of a sequence.

We want to find $a_7$ , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for $a_n$ to find the value of the 7th term of the sequence.

We show this below:

$a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15$

So the 7th term is "-15"

A flash disk has the capacity of storing 1 megabyte of data. How many kilobytes of data can be stored in the same flash disk

Luden [163]

For this sort of problem, you need to be familiar with prefixes.

So:

megabyte = $1 *10^6$ bytes

kilobyte = $1*10^3$ bytes

and a regular byte would just be $1$

Now, you will need to do a conversion:

$1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}$

I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are $1*10^6$ bytes!)

In the second fraction thought, remember one kilobyte is $1*10^3$ bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do $\frac{1kilobyte}{1*10^3bytes}$ , but I think it is more correct to do write it out how I did).
