Answer:
<em>The answer to your question would be D.</em>
<em>D. Range: 20</em>
<em>Mean: 10</em>
<em>Median: 9</em>
<em>Mode: none</em>
Step-by-step explanation:
1, 2, 3, 8, 9, 12, 14, 20, 21
Range: 21 - 1 = 20
Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10
Median: 9
Mode: there are no mode in the following given data set.
Answer:
x = 4
Step-by-step explanation:
(5x2 - 2x + 1) = (x - 1)
Simplify by multiplying 5 and 2.
(10 - 2x + 1) = (x - 1)
Combine like terms. Remove parentheses.
11 - 2x = x - 1
Cancel out - 2x to get the variable on one side.
- 2x + 2x = 0 x + 2x = 3x
11 = 3x - 1
Do the same with the 1.
12 = 3x
Divide.
x = 4
