The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally beli
Svetach [21]

Hi there :)

Question :

........

☆ The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

☆ The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.

☆ The scatter plot would not be represented by a line of best fit with a negative slope. There is a weak correlation between the football team playing at home and winning.

☆ There is no causation and almost no correlation between the football team playing at home and winning.

Direct Answer- <em><u>Option A</u></em>

<em>Answer Explanation -</em>

<u>r = -0.91</u>

Negative, so opposite directions, which can be explained as for example, the more the team travels(plays away games), the less games it wins.

| r | = 0.91, which is quite close to 1, so a significant relationship. Also, Negative relation means that the scatter plot would be represented by a straight line with a negative slope, and so,<em><u> correct answer is Option A</u></em>

<em>Method explanation :-</em>

Correlation coefficients measure the relationship between variables, the closer | r | is to 1, the stronger the relationship will be.

If the coefficient is positive, then there will be a positive relationship. If the coefficient is negative, then there is a negative relationship.

Simplify(7x^-2x+5)-(3x^2+4x+10)<br> show all steps
ad-work [718]
If we are looking to simplify two trinomials, it is easiest to put them on top of each other and subtract.

   7x²  - 2x  + 5                      7x² - 2x + 5
- (3x² + 4x + 10)                  -3x² - 4x - 10

4x² - 6x - 5
