I believe the correct response would be B. Real numbers and natural numbers.
Answer: 4 1/12
Step-by-step explanation:
Answer:
<u>Explanatory variable</u> (independent variable)
- The variable that affects the other variable.
- Drawn along the horizontal axis.
<u>Response variable</u> (dependent variable)
- The variable that is being affected.
- Drawn up the vertical axis.
(a) As the class wondered if they could <em>predict the father's height</em>, when they<em> know the son's height</em>
Explanatory variable = son's height
Response variable = father's height
(even though this is contrary to real-life, where the father's height would be used to predict the son's height)
(b) **see first attachment**
(c) The association is positive since the father's height increases as the son's height increases.
(d) **see second attachment**
Outlier = Paul (64.5, 73)
This point is far away from the majority of points on the scatter plot.
If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
Let the integers be x + (x+1) + (x + 2)
<span>x + (x+1) + (x + 2) = 267 </span>
<span>3x + 3 = 267 </span>
<span>3x = 264 </span>
<span>x = 88 </span>
<span>88+89+90=267 </span>
<span>Largest integer=90 </span>
<span>Another method </span>
<span>267/3 = 89 </span>
<span>It's the average,so it has to be the middle one. </span>
<span>Thus 89, then I took 89 - 1 = 88 and 89 + 1 = 90 and just put them in order. </span>
<span>88+89+90=267 </span>
<span>Largest integer=90</span>
