Answer:

Step-by-step explanation:

2 (x+4) = 3(x-2)

(distribute)

2*x + 2*4 = 3*x + 3 * -2

2x + 8 = 3x + -6

+6 +6 (add 6 on both sides)

2x + 14 = 3x

-2x -2x (subtract 2x on both sides)

14 = x

x is 14, we have found x.

3. Use the following table to answer questions (a – c).

sineoko [7]

Answer:

See below

Step-by-step explanation:

B) The correlation coefficient is $r=0.75$ , which can be determined by plugging the data into a TI-84 calculator.

C) A correlation coefficient of $r=0.75$ indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer $r$ is to 1, the stronger the positive correlation. The closer $r$ is to -1, the stronger the negative correlation. If $r$ is closer to 0, then there's no correlation.
