Answer:

x = 1

Step-by-step explanation:

4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides

8x + 4 - 3 = - 3x + 12

8x + 1 = - 3x + 12 ( add 3x to both sides )

11x + 1 = 12 ( subtract 1 from both sides )

11x = 11 ( divide both sides by 11 )

x = 1

Which best represents the center of the data set below?
MA_775_DIABLO [31]

Answer: mean = 318.3

Median =330

Mode= 200

Step-by-step explanation:

Mean (average) is the total sum of values in a given a data set ÷ number of values

= 3820/12

Mean= 318.3

Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2

Step 1: we rearranged the data set from least to highest value to give

200,200,220, 240,300,320,340,360,380,400,420 and 440

Median= 320 + 340/2

=660/2 = 340

Mode is the value with highest frequency in a given data set, from the given question, mode = 200
