3 0

Answer:

x = 9.9

Step-by-step explanation:

<u>Step 1:  Solve for x</u>

<em>Add 2.1 to both sides...</em>

-2.1 - x + 2.1 = -12 + 2.1

-x = -9.9

<em>Multiply both sides by -1...</em>

-x * -1 = -9.9 * -1

x = 9.9

Answer:  x = 9.9

Select the correct comparison.
Delicious77 [7]

The true comparison is the typical value is greater in set A. The spread is greater in set B.

<h3>What is the true comparison?</h3>

Spread is used to measure the variability of a data set. Range can be used to measure spread. Range is the difference between the largest number and the smallest number in the dataset.

  • Spread of set A =  7 - 5 = 2
  • Spread of set B = 8 - 1 = 7

The median can be used to measure the typical value of the dataset. Median is the number at the center of the data set.

  • Median of set A = 6
  • Median of set B = 4
