There are 5 crayons. Two are broken. What fraction of the crayons are not broken?.
Answer:
3/5 of the crayons are not broken since 2 are broken
The fraction of crayons that are not broken if out of 5 crayons, 2 of them being broken is 3/5
How to interpret the fraction?Suppose the fraction is proper (the numerator is smaller than the denominator).
Let it be \(\dfrac{a}{b}\)
Then, we can interpret it as:
\(\dfrac{a}{b}\) is "a" parts out of "b" parts of a thing.
Here, we're specified that:
5 crayons are there2 crayons are brokenThen we get:
Number of crayons that aren't broken = total crayons - number of broken crayons = 5 - 2 = 3
Thus, 3 out of 5 crayons are not broken.
Using fraction, we write it as:
\(\dfrac{3}{5}\)
We pronounce it as "three-fifth of total crayons are not broken".
Thus, the fraction of crayons that are not broken if out of 5 crayons, 2 of them being broken is 3/5

What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the sum of interior angles of the polygon be S
Now , the number of sides of the polygon n = 6 sides
So , Sum of Interior angles of a polygon with n sides is
nθ = 180° ( n - 2 )
Substituting the values in the equation , we get
nθ = 180° ( 6 - 2 )
nθ = 180° x 4
nθ = 720°
Therefore , the value of S = 720°
Now , the sum of measures of internal angles inside the polygon is
m∠S = 90°
S = 90° + ( 9x - 19 )° + 111° + ( 5x + 8 )° + 128° + ( 7x + 3 )°
On simplifying the equation , we get
( 9x - 19 )° + ( 5x + 8 )° + ( 7x + 3 )° + 329° = 720°
Subtracting 329° on both sides of the equation , we get
( 9x - 19 )° + ( 5x + 8 )° + ( 7x + 3 )° = 391°
And , on further simplification , we get
21x - 8 = 391
Adding 8 on both sides , we get
21x = 399
Divide by 21 on both sides , we get
x = 19
Now , the measure of m∠V = ( 5x + 8 )°
Substitute the value of x in the equation , we get
The measure of m∠V = ( 5 ( 19 ) + 8 )°
The measure of m∠V = 103°
Hence , the measure of angle m∠V = 103°

2. Ryan is writing the program for a video game.
For one part of the game he uses the rule (x,y)â(x-3,y+8) to move points on the screen.
(a) What output does the rule give when the input is (-7,-3)? Show your work.
(b) What output does the rule give when the input is (10,-5)? Show your work
(a) When the input is (-7,-3), the rule (x,y) → (x-3,y+8) moves the point 3 units to the left and 8 units up.
So we can apply this rule to the input (-7,-3) as follows:
(-7,-3) → (-7-3,-3+8)
(-7,-3) → (-10,5)
Therefore, the output is (-10,5).
(b) When the input is (10,-5), the rule (x,y) → (x-3,y+8) moves the point 3 units to the left and 8 units up. So we can apply this rule to the input (10,-5) as follows:
(10,-5) → (10-3,-5+8)
(10,-5) → (7,3)
Therefore, the output is (7,3).

Find the volume of a cylinder with these characteristics. Use ≈ 3.14 and round to the
nearest hundredth.
Diameter = 2
Height = 1
Step-by-step explanation:
To find the volume of a cylinder, we use the formula:
Volume = π x radius^2 x height
where π (pi) is a mathematical constant approximately equal to 3.14, radius is half of the diameter, and height is the distance between the two circular bases.
In your case, the diameter of the cylinder is 2, so the radius is half of that, or 1. The height of the cylinder is 1. Substituting these values into the formula, we get:
Volume = π x radius^2 x height
Volume = π x 1^2 x 1
Volume ≈ 3.14 x 1 x 1
Volume ≈ 3.14
Therefore, the volume of the cylinder with diameter 2 and height 1 is approximately 3.14 cubic units, rounded to the nearest hundredth.

Which problem can be solved using the equation shown?
Answer: The first one :)
Step-by-step explanation:
Consider an MDP with 3 states, A, B and C; and 2 actions Clockwise and Counterclockwise. We do not know the transition function or the reward function for the MDP, but instead, we are given with samples of what an agent actually experiences when it interacts with the environment (although, we do know that we do not remain in the same state after taking an action). In this problem, instead of first estimating the transition and reward functions, we will directly estimate the Q function using Q-learning.
By estimating the Q-function directly using Q-learning and updating it based on observed samples, we bypass the need to explicitly estimate the transition and reward functions. This approach allows us to learn the optimal policy without prior knowledge of the underlying dynamics of the MDP.
In Q-learning, the Q-function estimates the expected cumulative reward for taking a particular action in a given state. It is updated iteratively based on the agent's experiences. In this scenario, although we do not know the transition and reward functions, we can still use Q-learning to directly estimate the Q-function.
We initialize the Q-values arbitrarily for each state-action pair. Then, the agent interacts with the environment, taking actions and observing the resulting states and rewards. With these samples, we update the Q-values using the Q-learning update rule:
Q(s, a) = Q(s, a) + α [r + γ max(Q(s', a')) - Q(s, a)]
Here, Q(s, a) represents the Q-value for state s and action a, r is the observed reward, s' is the next state, α is the learning rate, and γ is the discount factor.
We repeat this process, updating the Q-values after each interaction, until convergence or a predetermined number of iterations. The Q-values will eventually converge to their optimal values, indicating the optimal action to take in each state.

Opposite interior angles in a parrelogram are the same
The sum of the interior angles of a quadrilateral is 360º
What we can figure out)
∠T is opposite ∠V
So, ∠T=∠V=64
360º-64º-64º=∠S+∠U

Given the set of the vectors from R3 s-000. h 1 1 2h 3h +1 a) Create the matrix whose columns are elements of S. b) Use the determinant of the created matrix to find the va
To create a matrix whose columns are the elements of the set S in R3, we form a matrix with the vectors (0, 0, 0), (1, 1, 2h), and (3h + 1). The determinant of this matrix can be used to find the value of h.
(a) The matrix whose columns are the elements of S is:
[0 1 3h + 1
0 1 0
0 2h 0]
(b) To find the determinant of this matrix, we can expand along the first row. The determinant is calculated as:
0 * det([1 0; 2h 0]) - 1 * det([0 0; 2h 0]) + (3h + 1) * det([0 0; 1 1])
Simplifying, we have:
0 - 0 + (3h + 1) * (1 - 0) = 3h + 1
Therefore, the determinant of the matrix is 3h + 1.
By setting the determinant equal to zero and solving the equation, we can find the value of h. However, since we don't have an equation or additional information, we cannot determine the specific value of h.

Using the normal approximation to the binomial, there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.
What is the missing information?This problem is incomplete, but researching it on a search engine, it asks the probability that the sum of these Bernoulli variables is of less than 60.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with \(\mu = np, \sigma = \sqrt{np(1-p)}\).The binomial distribution is a series of n Bernoulli trials with p probability of a success on each trial, hence the parameters for the binomial distribution are given as follows:
n = 100, p = 0.5.
The mean and the standard deviation are given by:
\(\mu = np = 100(0.5) = 50\).\(\sigma = \sqrt{np(1-p)} = \sqrt{100(0.5)(0.5)} = 5\)Using continuity correction, the probability that the sum is less than 60 is P(X < 59.5), which is the p-value of Z when X = 59.5, hence:
\(Z = \frac{X - \mu}{\sigma}\)
Z = (59.5 - 50)/5
Z = 1.9
Z = 1.9 has a p-value of 0.9713.
Hence there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

The joint probability density function of X and Y is given by f(x, y) = ce^(−x−2y) , 0 ≤ x < [infinity], 0 ≤ y < [infinity].
a. Find c.
b. Find P(X < 1, Y < 1).
c. Find P(X > Y ).
d. Find the distribution function of the random variable X − Y .
e. Are X and Y independent?
f. Compute the conditional density of X given that Y = y, where 0 ≤ y < [infinity].
a. the value of c is 2. b. the probability P(X < 1, Y < 1) is given by 1 - e^-1 - e^-2 + e^-3. c. P(X > Y ) is (-e^(-x-2y) + e^(-2y)y) + e^(-2y) - e^(-2y)y.
a. Finding the value of c:
To find the value of c, we need to integrate the joint probability density function (PDF) over the entire range of x and y and set it equal to 1, since the PDF must satisfy the normalization condition.
The joint PDF is given by f(x, y) = ce^(-x-2y)
∫∫f(x, y) dx dy = 1
∫∫ce^(-x-2y) dx dy = 1
Integrating with respect to x first:
∫[0,∞] ce^(-x-2y) dx = [-ce^(-x-2y)] [0,∞] = ce^(-2y)
Integrating the result with respect to y:
∫[0,∞] ce^(-2y) dy = [-1/2 * ce^(-2y)] [0,∞] = 1/2
Setting this equal to 1:
1/2 = 1/c
Solving for c:
c = 2
Therefore, the value of c is 2.
b. Calculating P(X < 1, Y < 1):
To find the probability P(X < 1, Y < 1), we need to integrate the joint PDF over the given region.
P(X < 1, Y < 1) = ∫[0,1] ∫[0,1] 2e^(-x-2y) dx dy
Integrating this expression, we get:
P(X < 1, Y < 1) = ∫[0,1] [-2e^(-x-2y)] [0,1] dy
= ∫[0,1] -2e^(-1-2y) + 2e^(-2y) dy
= [-e^(-1-2y) + e^(-2y)] [0,1]
= (-e^(-1-2) + e^(-2)) - (-e^(-1) + e^0)
= (-e^-3 + e^-2) - (-e^-1 + 1)
= 1 - e^-1 - e^-2 + e^-3
Therefore, the probability P(X < 1, Y < 1) is given by 1 - e^-1 - e^-2 + e^-3.
c. Finding P(X > Y):
To find the probability P(X > Y), we need to integrate the joint PDF over the region where X > Y.
P(X > Y) = ∫[0,∞] ∫[y,∞] 2e^(-x-2y) dx dy
Integrating this expression, we get:
P(X > Y) = ∫[0,∞] [-e^(-x-2y)] [y,∞] dy
= ∫[0,∞] -e^(-x-2y) + e^(-2y)y dy
= [-e^(-x-2y) + e^(-2y)y] [y,∞]
= (-e^(-x-2y) + e^(-2y)y) - (-e^(-2y) + e^(-2y)y)
= (-e^(-x-2y) + e^(-2y)y) + e^(-2y) - e^(-2y)y
