identify the sample space of rolling two six sided die at the same time
Answer:
The sample space of rolling two six-sided dice at the same time consists of all possible outcomes of the two dice. Each die can show any number from 1 to 6, so the sample space contains 6 x 6 = 36 possible outcomes.
Each outcome is represented by an ordered pair (a,b) where a and b are integers from 1 to 6 representing the numbers shown on each die, respectively. For example, (1,1), (1,2), (1,3),......., (6,5), (6,6) are all possible outcomes in the sample space.

The volume of a cylinder is 637 cm³. If the radius is 3 cm, what is the height
of the cylinder?
If the radius is 3 cm, the height of the cylinder is approximately 7.06 cm, which is closest to option B, 7 cm. The correct option is B.
The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.
We are given that the volume of the cylinder is 637 cm³ and the radius is 3 cm. Substituting these values into the formula, we get:
637 = π(3²)h
Simplifying:
637 = 9πh
h = 637 / (9π)
h ≈ 7.06
Thus, the height of the cylinder is approximately 7.06 cm, which is closest to option B, 7 cm.

a random number is selected uniformly from 0; 1; 2; 3; 4; 5; 6; 7 without replacement until 3 is chosen. let x denote the number of selection. find the entropy h(x) in bits
The entropy of the random variable X in this case is approximately 1.585 bits.
The entropy of a random variable X is a measure of the uncertainty associated with it. In this case, the random variable X is the number of selections required to choose the number 3.
Since the numbers are selected without replacement, the possible values for X are 1, 2, and 3, and the probabilities for each value are:
P(X=1) = 1/3
P(X=2) = 2/7
P(X=3) = 4/7
The entropy of a random variable X in bits is given by the formula:
H(X) = -∑P(X) log2(P(X))
Plugging in the probabilities above:
H(X) = -(1/3 log2(1/3) + 2/7 log2(2/7) + 4/7 log2(4/7))
H(X) = 1.585 bits
So, the entropy of the random variable X in this case is approximately 1.585 bits.

Step-by-step explanation:
A super large tank was initially filled with brine solution of 20 liters. At some point, fresh water starts to flow in at a rate of 8 liters per minute, and the well mixed solution flows out at half of the rate.Part I Set-up an Initial Value Problem to describe the above problem using: y(t) to represent the amount of salt in the tank t minutes after the process started. There was certain amount of salt in the tank initially,y0 to represent the initial amount.Part II Solve the above IVP to get y(t). Part III How much time (in minutes) will it take for the amount of salt in the tank be reduced to 20% of the initial amount?
The y(t) represents the amount of salt in the tank t minutes after the process started, and y(0) = 20 represents the initial amount. The y(t) is \(y(t) = 4 + 8t - \frac{1}{2} y^2\). It will take approximately 6.875 minutes for the amount of salt in the tank to be reduced to 20% of the initial amount.
From the given data,
A super large tank was initially filled with brine solution of 20 liters.
At some point, fresh water starts to flow in at a rate of 8 liters per minute, and the well mixed solution flows out at half of the rate.
The initial value problem (IVP) to describe the above problem can be set up as follows:
⇒\(\frac{d}{dt} y(t)=\frac{1}{2} (8-y(t))\)
⇒y(0)=20
Where y(t) represents the amount of salt in the tank t minutes after the process started, and y(0) = 20 represents the initial amount.
Part II:
To solve the IVP, we need to find y(t) for a given t. This can be done using numerical methods or analytical methods, such as separation of variables. Using separation of variables, we have:
⇒\(\frac{d}{dt} y(t)=\frac{1}{2} (8-y(t))\)
⇒\(\frac{dy}{dt}=\frac{1}{2}(8-y)\)
⇒2dy = (8 - y) dt
⇒2dy = (8 - y)dt
Integrating both sides with respect to t, we get:
⇒∫2dy = ∫(8 - y)dt
⇒2y = 8t - (1/2)y^2 + C
where C is a constant of integration. Using the initial condition y(0) = 20, we can find the value of C:
⇒\(2y=8t-\frac{1}{2}y^{2} +C\)
⇒\(2y=8t-\frac{1}{2}y^{2} +20\)
Solving for y, we get:
⇒\(y(t) = 4 + 8t - \frac{1}{2} y^2\)
Therefore, the y(t) is \(y(t) = 4 + 8t - \frac{1}{2} y^2\).
Part III:
To find the time it takes for the amount of salt in the tank to be reduced to 20% of the initial amount, we can solve for t when y(t) = 0.2 * y0:
⇒\(y(t) = 4 + 8t -\frac{1}{2}y^2 = 0.2 * y0\)
⇒\(4 + 8t - \frac{1}{2} y^2 = 0.2 * 20\)
Solving for t, we get:
⇒t =\(\frac{1}{8}\)(4 - 0.2 * 20) = approximately 6.875 minutes.
Hence, it will take approximately 6.875 minutes for the amount of salt in the tank to be reduced to 20% of the initial amount.

Farmer Elentire started with 71 dubbles on his farm. Every month, he
got 6 more of them. Farmer Hopt started with 10 dubbles on her farm.
Every month, she purchased 10 more of them.
Write a system of equations, in slope-intercept form, to model each
farmer's dubbles (y) as months (x) increase.
y= 71+ 6x
y= 10+ 10x
What pair of numbers solves the system? Use values accurate to the
nearest tenth.
The pair of numbers that solves the system is (15.25, 164.5).
The system of equations, in slope-intercept form, for Farmer Elentire and Farmer Hopt are:
y = 6x + 71 (for Farmer Elentire)
y = 10x + 10 (for Farmer Hopt)
To find the pair of numbers that solves the system, we need to find the point where the two lines intersect.
We can do this by setting the equations equal to each other:
6x + 71 = 10x + 10
Solving for x, we get:
4x = 61
x = 15.25
Now that we know x = 15.25, we can plug this value into either equation to find y.
71 + 6x = 10 + 10x
Subtracting 6x and 10 from both sides, we get:
61 = 4x
Dividing both sides by 4, we get:
x = 15.25
Now we can use either of the original equations to find y. Let's use the first equation:
y = 71 + 6x = 71 + 6(15.25) ≈ 164.5
Using the first equation, we get:
y = 6(15.25) + 71
y = 163.5
Therefore,
The pair of numbers that solves the system is (15.25, 163.5), accurate to the nearest tenth.

Answer: (5 × 8) - (5 × 1)
Step-by-step explanation:
When you use the distributive property, you essentially distribute a number to terms it is being multiplied by in order to make the calculation process easier.
When you use the distributive property, you distribute the number outside a multiplication statement to the numbers inside. In this case, 5 is the number outside, and 8 and 1 are the numbers inside.
When you distribute the number 5 to the eight, you are left with (5 × 8). However, you must still include 1, the other number in the parentheses, to finish the equation.
With 1, you go through the same process as you did before. You distribute the number 5 to the 1 and are left with (5 × 1). However, in the original equation, you are subtracting the 8 by the 1, so you must account for the subtraction sign.
You essentially subtract the number you get from (5 × 8) by the number you get from (5 × 1). Therefore, your answer is (5 × 8) - (5 × 1).

Step-by-step explanation:
1) The sample is the number of things picked out from a population. The amount of people surveyed is the sample, so it the answer choice showing "42 residents" as the sample is among a correct option. Since C is the only one with "42" as the sample, it is the answer.
2) Boosting morale isn't a negative thing, and will ultimately make residents happier. It leans towards "yes."
Adding a machine for enjoyment also leans towards "yes", because people will then have something fun to dsitract themselves with.
Many people will have access to the machine in the lunch room. They can also have a soft drink for lunch, which adds a tasty part to their lunch. It too leans towards "yes."
In a crowded lunchroom, the soft drink machine may be crowded by many people and it could take a while to get one for yourself. It is also vulnerable to breaking from too many people using it at once. It leans towards a "No" response.
Therefore, D is the best answer.

Find the value of x in the isosceles triangle. Round to the nearest tenth if necessary.
The value of x is 15 inches, we find this by Pythagoras theorem and property of isosceles triangle.
What is Pythagoras Theorem?Pythagoras theorem states that sum of square of base and square of perpendicular is equal to square of hypotenuses.
So , it can be formula is given below ,
\(perpendicular^{2} + base^{2} = hypotenuse^{2}\)
And In ab isosceles triangle two equal side vertex divide base in two equal parts.
So, here base = 40.
Therefore it is divided in 20-20 inches,
Now putting the formula of Pythagoras theorem, we get
\(20^{2} + x^{2} = 25^{2}\)
\(x^{2} = 25^{2} - 20^{2}\)
\(x^{2} = 225\)
