Answer:
B.
Step-by-step explanation:
h -234 = 1,192
-234 is a negative and if you add a negative number with a positive you have subtract and the remaining is your answer.
1,192+234=1,426
1,426-234=1,192
h=1,426
Answer:
We obtain same product by both the methods.
Step-by-step explanation:
We are given the following in the question:
Commutative property of multiplication:
Different ways to find the product:
1. First way
2. Second way
We get the same product for both the calculations.
The answer is 4. I but it has to be capital
Answer: C. there is still not enough evidence to conclude that the time series is stationary.
Step-by-step explanation: First thing to note for a time series plot is that it is required to select a suitable forecast method for the data set being considered.
A stationary time series means that the process generating the data set has a constant mean and the variations are constant over time. This means all evidence is present leading to the conclusion that the entire time series is stationary. A stationary time series thus exhibits an horizontal pattern which enables an appropriate forecast method to be selected for this type of pattern.
A horizontal pattern of a time series plot indicates that a data set fluctuates around a constant mean for a period of time. This period of time may however not be the entire time of the time series or take the entire data set into consideration and might just be a reflection of a portion of the time series hence why it can not be explicitly considered to be stationary. This means that a horizontal pattern can change into a seasonal or trending pattern if more variables/data are added over time.
For instance, a manufacturer sells a certain amount of products over a 10 week period and the resulting pattern of a time series plot is horizontal, then from the 11th week to the 15th week he gets a sharp and continuous increase in sales. This change in level will therefore change the time series plot from horizontal to trending making it more difficult to select a suitable forecast method.
Answer:
10
Step-by-step explanation:
1. The area of triangle is = (A*h)/2, where h is the height grounded on side A.
2. Given the height 5 and the side 4 we get S(area)=(5*4)/2=10.
