Answer:
D
Step-by-step explanation:
w>-3, and that doesn't include -3 itself, so it's everything above it.
-2, 1, 0, and beyond..
Answer:
B : a 20% increase in variable costs
Step-by-step explanation:
Here the industry is seeing a 20% increase in activity levels over the fourth quarter. Since, there has been an increase in activity levels the fixed cost would remain the same but the variable cost being variable would increase with increase in production activity in same proportion as the increase in production.
B : a 20% increase in variable costs
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.
V=pi*r^2*h*1/3
12pi=pi*r^2*4/3
R needs to be equal to 3 to be squared into 9 to make the equation true.
So the radius is 3 inches.
I hope this helps!
