Answer:
You do 2/3 times 30d minus 2/3 times 15. That will give you 20d - 10
Step-by-step explanation:
(2/3x30d) - (2/3x15) = 20d - 10
<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
Answer:
Inequality: 22 + 5x ≥ 59
Minimum amount: 7.4
Realistic number: 8
Represented on a graph: I think it would look like a vertical line starting at the x value of 8, and continue right forever
Step-by-step explanation:
22 because that's how much she has already, 5x will represent her earnings relative to the number of driveways she pressure washes, and greater than or equal to 59 because she needs $59 or more to buy the video game.
22 + 5x ≥ 59 (subtract 22 from each side)
5x ≥ 37 (divide each side by 5)
x ≥ 7.4
