The Surface area of the cone is; 200π cm²
The volume of the cone is; 320πcm³
What is the volume of the cone?The lateral area of the cone given in the task content can be evaluated as follows;
LA = πrl; where r = 8 from Pythagoras theorem.
LA = (8 × 17)π = 136π cm²
SA = πr(r +l) = 8π(25) = 200π cm²
The volume of the cone is;
V = (1/3)πr²h
V = 320πcm³

Answers
Answer:
68.75 feet tall
Step-by-step explanation:
Create a proportion where x is the height of the flagpole
[tex]\frac{x}{50}[/tex] = [tex]\frac{5.5}{4}[/tex]
Cross multiply and solve for x
4x = 275
x = 68.75
So, the flagpole is 68.75 feet tall

What is (2x^2+ 9x + 7) = (x + 1)?
A. 2x+11
B. 7x+7
C. 2x+7
D. X+1
Answers
What is (2x² + 9x + 7) = (x + 1) ?
Solution:-2x² + 9x + 7 = x + 1
2x² + 9x - x + 7 - 1 = 0
2x² + 8x + 6 = 0
2(x² + 4x + 3) = 0
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x( x + 3) + 1(x + 3) = 0
(x + 3)(x + 1) = 0
So, option (D) x + 1 is correct. [Answer]

There are twenty classes at each of two middle schools. The number of students in each class at each school is shown in the dot plots below.
Number of Students in Each Class at Poplar Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There are 3 dots above 20, 5 above 21, 7 above 22, 4 above 23, 1 above 24, and 0 above 25, 26, 27, 28, and 29.
Number of Students in Each Class at Oak Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There is 1 dot above 20, 2 above 21, 2 above 22, 4 above 23, 3 above 24, 2 above 25, 2 above 26, 2 above 27, 1 above 28, and 1 above 29.

Answers
The dot plot is missing, so i have attached it.
Answer:
B: there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
Step-by-step explanation:
From the dot plot attached, we can find the average number of students per class for each school.
For Poplar Middle School;
Total number of students = (20 × 3) + (21 × 5) + (22 × 7) + (23 × 4) + (24 × 1) = 435 students.
There are 20 classes.
Thus;
average number of students per class = 435/20 = 21.75
For Oak Middle School;
Total number of students = (20 × 1) + (21 × 2) + (22 × 2) + (23 × 4) + (24 × 3) + (25 × 2) + (26 × 2) + (27 × 2) + (28 × 1) + (29 × 1) = 483
Average number of students per class ; 483/20 = 24.15
Difference in average = 24.15 - 21.75 = 2.40
This implies that there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Step-by-step explanation:
A woman applies a force of 300 Newtons to push a stroller 100 meters. It takes her
60 seconds to perform this work. Use the equations W = Fd and P = W x T
calculate her power.
Answers
Answer:
Work done by the woman is 500 joule per second.
Step-by-step explanation:
Force applied by the woman = 300 Newtons
Total displacement due to force = 100 meters
Work done = Force applied × Displacement due to force
= 300 × 100
= 30000 Joule
Since, Power = [tex]\frac{\text{Work done}}{\text{Time taken to perform the work}}[/tex]
= [tex]\frac{W}{t}[/tex]
= [tex]\frac{30000}{60}[/tex]
= 500 Joule per second
Therefore, work done by the woman is 500 joule per second.

Suppose a polling agency reported that 48.0% of registered voters were in favor of raising income taxes to pay down the national debt. The agency states that results are based on telephone interviews with a random sample of 1033 registered voters. Suppose the agency states the margin of error for 95% confidence is 3.0%. Determine and interpret the confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. ▼ We are 48.0% confident There is a 95% probability We are 95% confident There is a 3.0% probability We are 1033% confident We are 3.0% confident There is a 48.0% probability There is a 1033% probability that the proportion of ▼ all Americans registered voters adult Americans aged 18 or older in favor of raising income taxes to pay down the national debt is between nothing and nothing
Answers
Answer:
The 95% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt is (45%, 51%). This means that we are 95% sure that the true proportion of all registered voters who are in favor of raising income taxes to pay down the national debt is between these two values, of 45% and 51%.
Step-by-step explanation:
A confidence interval is the sample proportion plus/minus the margin of error.
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
Sample proportion of 48%.
Suppose the agency states the margin of error for 95% confidence is 3.0%. Determine and interpret the confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.
48% - 3% = 45%
48% + 3% = 51%
The 95% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt is (45%, 51%). This means that we are 95% sure that the true proportion of all registered voters who are in favor of raising income taxes to pay down the national debt is between these two values, of 45% and 51%.
