The height of a cone is twice the radius of its base.
What expression represents the volume of the cone, in
cubic units?
2/3лх^3
4/3лх^3
2лх^3
4лх^3
Answer: 2/3πx³
Step-by-step explanation:
Let the radius of the cone be represented by x.
Since the height of the cone is twice the radius of its base, the height will be: = 2x
Volume of a cone = 1/3πr²h
where,
r = x
h = 2x
Volume of a cone = 1/3πr²h
= 1/3 × π × x² × 2x
= 1/3 × π × x² × 2x
= 1/3 × π × 2x³
= 2/3πx³
Therefore, the correct answer is 2/3πx³.
The dimensions of a rectangular Pyramid are shown in the diagram below what is the volume of the rectangular pyramid in cubic
Answer:
160 in³
Step-by-step explanation:
Volume of rectangular pyramid, V = (Length * width * height) / 3
Length = 10 in ; width = 8 in ; height = 6 in
V = (10 * 8 * 6) / 3
V = 160 in³
After standardizing a NaOH solution, you use it to titrate an HCl solution known to have a concentration of 0.205 M. You perform five titrations and obtain the following results: 0.213, 0.204, 0.208, 0.200, and 0.198 M.
a) What is the mean?
b) What is the standard deviation of mean?
Answer:
The right answer is:
(a) 0.205
(b) 0.005425
Step-by-step explanation:
The given data is:
0.213, 0.204, 0.208, 0.200, and 0.198
(a)
The mean will be:
= [tex]\frac{Sum \ of \ all \ data}{No. \ of \ data}[/tex]
= [tex]\frac{0.213+ 0.204+ 0.208+ 0.200+0.198}{5}[/tex]
= [tex]\frac{1.023}{5}[/tex]
= [tex]0.2046[/tex]
or,
= [tex]0.205[/tex]
(b)
The standard deviation will be:
[tex]\sigma^2=\Sigma\frac{(x_i-\mu)^2}{N}[/tex]
[tex]=\frac{(0.213-0.2046)^2+...+(0.198-0.2046)^2}{5}[/tex]
[tex]=\frac{0.0001472}{5}[/tex]
[tex]=2.994\times 10^{-5}[/tex]
or,
[tex]=0.005425[/tex]

The box in a triangle always represents a right angle
Answer:
The missing angle is 65 degrees
Step-by-step explanation:
Answer: 65 degrees
First, you can make the conclusion that a right angle is 90 degreesNext, you can add 90 to 25 to get 115You then subtract 115 from 180.You are left with 65, which is the measure of the missing angleRemember that a triangle equals 180 degrees! :)Which student had the highest average (mean) score?

Fill in the blanks using the following choices: reject, fail to reject, sufficient, enough, not sufficient, not enough If the p value is 0.32 to test if there is a difference exists between the proportion of students who have ear infections at one school and the other, your decision is to the null and the conclusion: There is evidence to support the alternative that the proportion of students who have ear infections at one school and the other are different.
Answer:
FAIL TO REJECT
NOT ENOUGH
Step-by-step explanation:
Given a Pvalue of 0.32
Decision region :
When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.
Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis
Therefore, for the scenario above, where Pvalue = 0.32
Possible α values are ; 0.1, 0.05, 0.01
For all α - values listed, the Pvalue is greater than α
Pvalue > α ; Hence, FAIL TO REJECT the Null.
Conclusion :
There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.
if the nth term of a sequence is 2n+2n squared, find the first 3 terms and the 10th term please help
Answer:
3rd term: 24
10th term: 220
Step-by-step explanation:
For the 3rd term
2*3 + 2*(3^2) = 6 + 2*9 = 6 + 18 = 24
For the 10th term
2*10 + 2*(10^2) = 20 + 2*100 = 20 + 200 = 220

Sara can finish 5 laps around the track in 6 minutes. What is her average speed in miles per hour, if it takes 12 laps around the track to run a mile?
9514 1404 393
Answer:
4 1/6 miles per hour
Step-by-step explanation:
6 minutes is 1/10 hour, so Sara's speed is ...
speed = distance/time
speed = (5/12 mi)/(1/10 h) = 50/12 mi/h
speed = 4 1/6 mi/h
Sara's speed is 4 1/6 miles per hour.

Mr. A is white, non-hispanic, 20 years old, and a high school dropout. Using the probit regression, assuming that Mr. A is not subject to a workplace smoking ban, calculate the probability that Mr. A smokes. Carry out the calculation again, assuming that he is subject to a workplace smoking ban. What is the effect of the smoking ban on the probability of smoking
Answer: Hi Your question lacks some information but i will give you a general solution with similar data found online
answer
a) 15.15%
b) The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%
Step-by-step explanation:
Using The probit regression
from the attached question ;
for smoking
1 = smokes , 0 = do not smoke
For Independent variable
1 = ban at workplace , 0 = not ban at workplace.
sex : male = 0 , female = 1
a) Assuming Mr. A is not subject to a workplace smoking ban
P ( Mr. A smokes ) = 15.15%
b) Assuming Mr. A is subject to a workplace smoking ban
determine effect on P ( Mr. A smokes )
The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

The total area is 360 square meter.
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.
Given:
We get Three Rectangle
First Rectangle:
length = 12 m
width = 16 m
So, Area = 12 x 16 = 192 square meter.
Second Rectangle:
length = 8 m
width = 12 m
So, Area = 8 x 12 = 96 square meter.
Third Rectangle:
length = 12 m
width = 6 m
So, Area = 12 x 6 = 72 square meter.
Thus, the total area = 192 + 96+ 72 = 360 square meter.
