Remark

In order for the figure to be a parallelogram, the 2 parts of the same diagonal must be equal.

Equation

Therefore 79 - y = 2y + 22 Add y to both sides.

Solution

79 = 2y + y + 22 Combine

79 = 3y + 22 Subtract 22 from both sides

79 - 22 = 3y Combine like terms

57 = 3y Divide by 3 on both sides

57/3 = y Divide

19 = y

Answer y must be 19

Edit

For x you would have to obey the same principle.

3x + 1 = x + 27 Subtract x from both sides

3x - x + 1= 27 Combine like terms

2x + 1 = 27 Subtract 1 from both sides

2x= 27 - 1 Combine the right

2x = 26 Divide by 2 on both sides.

2x/2 = 26/2

x = 13

I am pretty sure y would be 79

In Problems 1-8, determine the level of measurement of each variable.

lbvjy [14]

The level of measurement of each given variable are:

1. Ordinal

2. Nominal

3. Ratio

4. Interval

5. Ordinal

6. Nominal

7. Ratio

8. Interval

Level of measurement is used in assigning measurement to variables depending on their attributes.

There are basically four (4) levels of measurement (see image in the attachment):

1. Nominal: Here, values are assigned to variables just for naming and identification sake. It is also used for categorization.

Examples of variables that fall under the measurement are: Favorite movie, Eye Color.

2. Ordinal: This level of measurement show difference between variables and the direction of the difference. In order words, it shows magnitude or rank among variables.

Examples of such variables that fall under this are: highest degree conferred, birth order among siblings in a family.

3. Interval Scale: this third level of measurement shows magnitude, a known equal difference between variables can be ascertain. However, this type of measurement has no true zero point.
