Answer:
3.7
Step-by-step explanation:
I believe that it's no,<span> it is not a valid inference because her classmates do not make up a random sample of the students in the school. But I can't be sure, I really haven't done much on inferences, especially in math. I know for sure that her inference is incorrect though. Hope this helps, even a bit!</span>
There should be a .94 increase making it be 141.94 at the end of the week.
Answer:
<h3><u>x= -23</u> is the right answer.</h3>
Start with the formula of the volume of a cone
volume of cone = (1/3) pi * r^2 * h
Now you double the radius and the height.
The radius becomes 2r, and the height becomes 2h.
volume of cone = (1/3) pi * (2r)^2 * 2h
= (1/3) pi * 4r^2 * 2h
= (1/3) pi * 8r^2 * h
= 8 * (1/3) pi r^2 * h
As you can see, the volume became 8 times larger.
8 * 350 cm^3 = 2800 cm^3
