2x+7x what is the answer to this

Mathematics

Oksi-84 [34.3K]2 years ago

Answer:

9x

Step-by-step explanation:

X is an unknown variable so just leave x as it is

Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things

Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.

It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.

2+7=9 therefore your answer should be 9x

Listed below are the numbers of hurricanes that occurred in each year in a certain region. The data are listed in order by year.
Schach [20]

Answer: C. The measures of variation reveal nothing about the pattern over time.

Step-by-step explanation:

Given the following :

10 17 10 16 11 3 8 5 4 4 17 5 8 17

Range of hurricane data = 16

The standard deviation of sample data = 5.5 hurricanes

The variance of the sample data is 30.3 hurricane^2.

The measures of variation described above only shows the spread of the hurricane such as the range, that is the highest and lowest recorded.

The variance explains how spread out the data is and the standard deviation explains how values of a data differs from the mean value. The data fails to give time related information or pattern.
