Answer:

For part A: Range is difference between the highest value and lowest value of the data set.

For part B: Range is 5.2

Step-by-step explanation:

For part A:

Range of a data set is difference between the highest value and lowest value of the data set.

For part B:

From stem and leaf and it's key ,we can write our data set as

12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.

Lowest value of data set = 12.3

Highest value of the data set =17.5

So, range = highest value- lowest value= 17.5-12.3 =5.2

(25 POINTS!) Identify the like terms, explain how you know they are
Hatshy [7]

Answer:

Step-by-step explanation:

Like terms: 10y, -2y, 3x, and x

These are all like terms since they have a similar variable

Simplifying the expressions:

10y + 3x + 10 + x -2y = [(10y + -2y) + (3x + x)] + 10

= 8y +  4x + 10

Like terms: 3x, 4x, y, and -2y

Same as first explanation, terms have a similar variable

3x - y + 4x + 6 - 2y = (3x + 4x) + (-2y - y) + 6

= -3y + 7x + 6

Hope I helped :)
