All edges of a cube are expanding at a rate of 3 centimeters per second. How fast is the volume changing when each edge is 10 centimeters
Answers
The time it takes for the volume to change when each edge is 10 centimeter would be = 3.3sec
What is a cube?A cube is a type of solid shape that has six number of faces, eight number of vertices and twelve number of edges.
The cube with edges of 3 cm = 1 second
When the cube has edges of 10 cm = X seconds
Make X seconds the subject of formula;
X seconds = 10 × 1/3
X seconds= 3.3sec
Therefore, it will take 3.3 secs for the volume to change when each edge is 10 centimeter.

A probability distribution has a mean of 50 and a standard deviation of 2.
Use Chebyshev's inequality to find the minimum probability that an outcome is between 37 and 63. (Round your answer to four decimal places.)
Answers
The minimum probability that an outcome is between 37 and 63 is 97.67%.
In this case, we want to find the minimum probability that an outcome is between 37 and 63. To use Chebyshev's inequality, we need to first calculate the distance between the mean and each of these values in terms of standard deviations.
The distance between the mean and 37 is (50-37)/2 = 6.5 standard deviations, and the distance between the mean and 63 is (63-50)/2 = 6.5 standard deviations as well.
We can then use Chebyshev's inequality to find the minimum probability that an outcome is within 6.5 standard deviations of the mean:
P(|X - μ| < kσ) ≥ 1 - 1/k²
where P is the probability of an outcome being within a certain distance from the mean, X is the value of the outcome, μ is the mean, σ is the standard deviation, and k is the number of standard deviations away from the mean.
Substituting the values we have, we get:
P(37 < X < 63) = P(|X - 50| < 6.5x2)
≥ 1 - 1/(6.5)²
≥ 1 - 0.02326
≥ 0.9767
Therefore, we can conclude that the minimum probability that an outcome is between 37 and 63 is 0.9767. In other words, at least 97.67% of the data falls within 6.5 standard deviations from the mean.

A golf ball rolls at a speed of 8 m/s for 12 seconds. Mandy hits the golf ball and it rolls
for 16 seconds at a speed of 12 m/s. What is the total distance travelled by the golf ball?
Answers
Using the given information, the total distance travelled by the golf ball is 288 m
Calculating the total distance travelled by the golf ballFrom the question, we are to calculate the total distance travelled by the golf ball
The distance travelled by the golf ball can be calculated by using the formula,
Distance = Speed × Time
From the given information,
The golf ball rolls at a speed of 8 m/s for 12 seconds
Thus,
The distance travelled at this time is
Distance = 8 m/s × 12 s
Distance = 96 m
Also,
Mandy hits the golf ball and it rolls for 16 seconds at a speed of 12 m/s
The distance travelled at this time is
Distance = 12 m/s × 16 s
Distance = 192 m
The total distance travelled by the golf ball is 96 m + 192 m
=
Hence, the total distance travelled by the golf ball is 288 m

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Isabella sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
105 visitors purchased no costume.
41 visitors purchased exactly one costume.
8 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth.
Answers
The probability that the next person will purchase one or more costumes can be found by dividing the number of visitors who purchased one or more costumes by the total number of visitors.
The total number of visitors is 105 + 41 + 8 = 154.
The number of visitors who purchased one or more costumes is 41 + 8 = 49.
So the probability that the next person will purchase one or more costumes is 49/154, which is approximately 0.32 to the nearest hundredth.

A spherical chocolate covered candy hasa diameter of 8cm. 4Part of the candy is a chocolate shell thatis .5cm thick.What is the volume ofjust the chocolate shell?
Answers
We want to calculate the volume of the spherical shell of chocolate.
The chocolate shell is spherical with a thickness of 0.5cm
Volumes of spherical shells can be calculated with the formula;
\(V_{shell}=\frac{4}{3}\pi(R^3-r^3)\)The outer diameter is 8cm. The outer radius is therefore 4cm
The inner diameter is 8-2(0.5)=7cm. The inner radius is therefore 3.5cm
Therefore, we can find the volume of the chocolate shell as;
\(V_{shell}=\frac{4}{3}\pi(4^3-3.5^3)=88.5\operatorname{cm}^3\)Therefore,
\(V_{shell}=88.5\operatorname{cm}^3\)Which percent is equivalent to 2 5/6?

What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
First, 7+3²-2⋅5
Solving the above expression
= 7 + 9 -2.5
= 16 - 2.5
= 13.5
Second,
(3/4+1/8)÷1/8
= (6/8 + 1/8) ÷ 1/8
= 7/8 ÷ 1/8
= 7/8 x 8/1
= 7
Hence, 7+3²-2⋅5 > (3/4+1/8)÷1/8.
