Smoothing a time series of observations A. is a form of statistical cheating. B. allows statisticians to use less data than woul

DedPeter [7]

Answer:

D. is used to reveal an underlying pattern in the data.

Step-by-step explanation:

Smoothing a time series is achieved when a computer uses some pre-programmed calculation methods to remove noise from large volumes of data. Smoothing helps a user detect patterns in a set of data, thus making it possible to make future predictions. For example, smoothing can be used in the prediction of the rise and fall of stock prices. This helps the traders to have an idea of what to expect in the cost of trading.

Although smoothing reveals the patterns in a set of data, it provides no explanation as to why it is so. It is left to the researcher to draw conclusions as to the reasons for the patterns.

Johnny played 31/2 video games in an hour.How many could be play in 40 minutes ?

REY [17]

<u>Answer: </u>

Johnny could play $2\frac{1}{3}$ video games in 40 minutes.

<u>Explanation:</u>

Given:

Johnny played video games in an hour = $3\frac{1}{2}$

To Find:

Video games Jonny can play in 40 minutes =?

Solution:

number of videos games Jonny can play in 1 hour = $3 \frac{1}{2}$ = $\frac{7}{2}$

And as 1 hour = 60 minutes ,

So number of videos games Jonny can play in 60 minutes = $\frac{7}{2}$

=> Videos games Jonny can play in 1 minute = ${\frac{\frac{7}{2}}{60}$

=> $\frac{7}{20\times 6}$

=> $\frac{7}{120}$

=> Videos games Jonny can play in 40 minute = 40 x Videos games Jonny can play in 1 minute

=> Videos games Jonny can play in 40 minute = $40 \times \frac{7}{120}$

=> $\frac{7}{3}$ = $2\frac{1}{3}$

Hence Johnny could play $2\frac{1}{3}$ video games in 40 minutes.

An electricity company charges its customers a fixed base charge of $6 a month, plus 10 cents per kilowatt-hour (kWh) for the fi

ryzh [129]

Answer:

$E(k)= \left[ \begin{array}{c} {6+0.10k\,\,if\,\,0\leq k \leq500} & 6+500\times0.10+0.11(k-500)\,\,if\,\,5001000\end{array}$

Step-by-step explanation:

The cost function has 3 branches,

Consumptions less than 500
Consumptions less than 1000
consumptions above a 1000

So the first branch the consumer pays 6 dollars plus .10cents for any additional kWh (k)

In the second, they pay the same as the first up to 500kWh, and after that they pay 0.11 for the additional kWh above 500: (k-500) but bellow 1000

In the third branch, for consumptions above 1000, they pay the fix amount, plus .10 for the first 500 ( $500\times0.10$ ) , .11 for the additional 500 ( $500\times0.11$ ) , and finally 0.15 for consumptions above 1000: $0.15(k-1000)$
