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.

steposvetlana [31]

Answer:

b = 3.1

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

The equation of three other functions are given which function or functions have a slope equal to the slope of Function 1
ratelena [41]

Answer:

See Explanation

Step-by-step explanation:

Required

Function(s) with the same slope as function 1

The question is incomplete as function 1 and the three additional functions are not given.

However, I will provide a general explanation.

A slope is represented as:

y = mx + b

Where

m \to slope

So, considering the following equations

y = 2x + 3

y = \frac{3x}{2} + 9

y = 2x - 5

y = -2x + 3

The following equations have the same slope

y = 2x + 3 and y = 2x - 5

Because: y = mx + b implies that:

m = 2 for y = 2x + 3 and y = 2x - 5

NCr/nPr=r!<br><br> give proof.
Sergio [31]
<span>It's 1/r! 

nCr = n! / r!(n-r)! 
nPr = n! / (n-r)! 

If you divide the two you'd have: 

n! / r! (n-r)! * (n-r)! / n! = 1/r!

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
