<span>Simplifying 9x + -2y = 19 Solving 9x + -2y = 19 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. 9x + -2y + 2y = 19 + 2y Combine like terms: -2y + 2y = 0 9x + 0 = 19 + 2y 9x = 19 + 2y Divide each side by '9'. x = 2.111111111 + 0.2222222222y Simplifying x = 2.111111111 + 0.2222222222y</span>

Contact [7]

Answer:

1. Median = 10.1

2. A. The median represents the center.

3. D. The​ mode(s) can't represent the center because it​ (they) is​(are) not a data value.

Step-by-step explanation:

Mean of a sample = sum of the samples/no of the samples

Samples in increasing order:

9.8

9.8

9.9

10.1

10.4

10.6

11.1

Mode is the sample with highest frequency.

Median is the middle entry of the data.

Mean = (9.8 + 9.8 + 9.9 + 10.1 + 10.4 + 10.6 + 11.1)/7

= 717/7

= 10.243

Median = 10.1

Mode = 9.8 because it has the highest frequency of 2
