Step-by-step explanation:
First, find the slope between the points.
m = (y₂ − y₁) / (x₂ − x₁)
m = (24 − 17) / (20 − 15)
m = 7/5
Next, write the equation in point-slope form, using either of the points.
y − 17 = 7/5 (x − 15)
If desired, simplify.
y − 17 = 7/5 x − 21
y = 7/5 x − 4
15/16 as a fraction or 3.125 as a decimal
An example scenario is:
Anthony goes to the gym for <em>20</em> minutes on Monday. Every day he <em>multiplies</em> his gym time by <em>2</em>.
On the fifth day, he will spend spend 320 minutes in the gym.
The formula used to determine the 5th term is,
a5 = 20 x 2^(r -1)
where r is the common ratio equal to 2.
Answer:
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.

Answer: Choice C</h3>
Explanation:
As the person spends more time raking, the number of leaves will go down. Therefore, we have a negative correlation. Such correlations occur when one variable goes up while the other goes down (and vice versa).
The reason why it's considered negative correlation is because the regression line has a negative slope.
This is why choice C is the answer. This assumes that no extra leaves fall on the ground, and we assume that we don't have nearby leaves blow into the yard.
In contrast, something like choice A has both variables go up together. As the temperature rises, so does the ice cream sales. The same goes for choice B. We consider these cases to have positive correlation. Choice D doesn't appear to have any correlation at all. The person's height doesn't have any connection to the number of pets they may have.
