The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.

So we have an equation:
2w=12-4w
Firstly, let's simplify, and divide all terms by 2:
w=6-2w
Now, we add 2w over to the other side:
3w=6
And finally, we divide both sides by 3:
w=2
Hope this helps!
Answer: a) 
b) 
Step-by-step explanation:
Given : Sample size of respondents in the exit polls : n= 2020
Number of respondents voted for George Bush = 412
Sample proportion: 
a) Critical value for 99% confidence level : 
Confidence interval for proportion:-


Hence, the 99% confidence interval for the proportion of college graduates in Ohio that voted for George Bush: 
b) Critical value for 95% confidence level : 
Lower confidence bound for the proportion :

Hence, a 95% lower confidence bound for the proportion of college graduates in Ohio that voted for George Bush : 
30 calories in one coffee cup that contains sugar and milk
Multiply numerator and denominator by

Things should simplify pretty nicely.
