Answer:
D
Step-by-step explanation:
Given a correlation coefficient of -.11 the correlation would be extremely weak therefore it would have almost no correlation or causation
Why? Well when the value of the correlation is between -.1 and .1 then the relationship is said to have no correlation
-.11 is very close to -.1 thus meaning it would have pretty much no correlation
(3, - 2)
given y = - 2, then
- 2x + 4 = - 2 ( solve for x )
subtract 4 from both sides
- 2x = - 6 ( divide both sides by - 2 )
x =
= 3

Answer:
Absolute value means the distance between a number and 0.
Examples:
The absolute value of -7 is 7.
The absolute value of 5 is 5.

The absolute value sign is |x|, where x is any real number.
The absolute value removes any negative sign in front of a number.
Answer:
13.75
Step-by-step explanation:
The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):
(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.
