Manipulate the radius and height of the cone, setting different values for each. Record the radius, height, and exact volume of the cone in terms
of m). The first one has been done for you. Also calculate the decimal value of the volume, and verify that it matches the volume displayed by the
tool (You might see some discrepancies in the tool due to rounding of decimals.)
Answer:
The decimal value of the volume already given= 1885.2 unit³
For radius 11 unit height 12 unit
Volume= 484π unit³
Volume= 1520.73 unit ³
For radius 4 unit height 6 unit
Volume= 32π unit³
Volume= 100.544 unit³
For radius 20 unit height 15 unit
Volume= 2000π unit³
Volume= 6284 unit³
Step-by-step explanation:
The decimal value of the volume already given= 600π
The decimal value of the volume already given= 600*3.142
The decimal value of the volume already given= 1885.2 unit³
For radius 11 unit height 12 unit
Volume= πr²h/3
Volume= 11²*12/3 *π
Volume= 484π unit³
Volume= 1520.73 unit ³
For radius 4 unit height 6 unit
Volume = πr²h/3
Volume= 4²*6/3(π)
Volume= 32π unit³
Volume= 100.544 unit³
For radius 20 unit height 15 unit
Volume= πr²h/3
Volume= 20²*15/3(π)
Volume= 2000π unit³
Volume= 6284 unit³

Step-by-step explanation:
Charlie and Violet met for lunch at a restaurant between their two locations (exactly in the middle). It took
Charlie 2.6 hours to get there, but it only took Violet two hours because she was driving 15 mph faster than
Charlie. The distance between the two of them initially was 260 miles. Find the speed of the two drivers.
Charlie
Violet
mph
mph
Answer:
Charlie 55 miles per hour
Violet 65 miles per hour
Step-by-step explanation:
Charlie and Violet met for lunch at a restaurant between Memphis and New Orleans. Since, Charlie left Memphis and drove towards New Orleans, and Violet left New Orleans and drove towards Memphis, the total distance that they covered altogether is the total distance between Memphis and New Orleans.
It is given that the distance between Memphis and New Orleans is 394 miles. This means, the total distance both covered = 394 miles
Charlie drove for 4.8 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour
Since, distance = speed multiplied by time
Distance covered by Charlie = 4.8x
Distance covered by Violet = 2(x + 10)
Altogether they covered 394 miles,
So,
394 = Distance covered by Charlie + Distance covered by Violet
394 = 4.8x + 2(x + 10)
394 = 4.8x + 2x + 20
374 = 6.8x
x = 55
Since, x represents the speed of Charlie, the speed of charlie was 55 miles per hour and speed of Violet was 65 miles per hour

Answer:
Step-by-step explanation:

1 0.41
2 0.38
3 0.13
4 0.03
5 0.01
X= 1
.13+.03+.01=0.17 (the amount with 3 or more cars)
0.17/1(Total amount of all probability)= 0.17 has 3 or more cars.
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that an adult resident has 3 or more is 0.17
What is probability?
It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The probability distribution of the number of vehicles is given as,
P(x) where x is the number of vehicles.
P(0) = 0.4
P(1) = 0.41
P(2) = 0.38
P(3) = 0.13
P(4) = 0.3
P(5) = 0.1
The probability that an adult resident has 3 or more.
= P(3) + P(4) + P(4)
= 0.13 + 0.03 + 0.01
= 0.17
Thus,
The probability that an adult resident has 3 or more is 0.17

An occupational safety officer for a large company is conducting a study to investigate back problems in office workers who use a computer for most of the workday. The study will
investigate the difference in back problems for workers who stand and workers who sit. A group of 68 volunteers have agreed to participate in the nine-month study. Half the group
is randomly assigned to work while standing, and the other half is assigned to work while sitting. At the end of the study, the mean number of back problems between the two
groups will be calculated. The officer will use the results to estimate the difference in the mean number of back problems between those who work while standing and those who
work while sitting
Which of the following is an appropriate inference procedure for the study?
Answer:
Answer is E
Step-by-step explanation:
did the test, also person who answered before was wrong
Considering the situation described, the appropriate test is given by:
E) A two sample t-interval for difference between population means.
When to use the t-distribution and the z-distribution?If we have the standard deviation for the sample, the t-distribution is used.If we have the standard deviation for the population, the z-distribution is used.In this problem, we will have the data from the sample, hence it is a t-test. We will compare the population means of the two groups, hence a two-sample t-interval is used, and option E is correct.

Which of the following statements is NOT true about the graph of a system of equations with no solutions?
A. The lines will have the different slopes.
B. The lines will have different y-intercepts.
C. The lines will share none of the same points.
D. The lines will have the same slope.
Answer:
A
Step-by-step explanation:
A would be the best answer here because equations with no solutions would be parallel. That means they would have the same slope but with different y-intercepts. Since where the equations share points would be the solution, they cannot share points either.

The area of a rectangular sheet of metal is 135 square inches. The perimeter is 48 inches. What are the dimensions of the sheet?
Answer: The length is 15 inches and breadth is 9 inches
Step-by-step explanation:
Given : Area of rectangular sheet = 135 square inches
Perimeter of rectangular sheet = 48 square inches
Now Area of rectangular sheet = [tex]Length\times Breadth[/tex] = 135 square inches
perimeter of rectangular sheet = [tex]2\times (Length+Breadth)[/tex] = 48 square inches
Thus [tex](Length+Breadth)[/tex] = 24 square inches
Thus Length = 15 inches
Breadth = 9 inches
