Answer:
option a is the answer to the question
ASAP. If a central angle has a measure of 100 degrees, determine the approximate length of the arc created by the two radii measuring 4 inches. Convert your answer to radians. Round your answer to two decimal places.
Answer:
234.9 million km
Step-by-step explanation:
The central angle is a quarter of a circle: 360° / 4 = 90°. Use the central angle calculator to find arc length. You can try the final calculation yourself by rearranging the formula as: L = θ * r. Then convert the central angle into radians: 90° = 1.57 rad, and solve the equation: L = 1.57 * 149.6 million km. L = 234.9 million km.
A pool has a length that is 3 times the width. Write the algebra radical value of the corner to corner distance
Answer:
The distance between corner to corner is equal to √10 times the width.
D = √10*W
Step-by-step explanation:
For a rectangle of length L and width W, the distance between two opposite corners can be calculated if we use the Pythagorean's theorem, where we can think on the length as one cathetus, the width as another cathetus and the diagonal as the hypotenuse.
Then the length of the diagonal is:
D^2 = L^2 + W^2
D = √( L^2 + W^2)
In this case we know that the length is 3 times the width, then:
L = 3*W
Replacing this in the equation for the diagonal we have:
D = √( (3*W)^2 + W^2) = √( 9*W^2 + W^2)
D = √( 10*W^2) = √10*√W^2 = √10*W
D = √10*W
The distance between corner to corner is equal to √10 times the width.
Now consider the so-called random walk with absorbing barriers on 1 = {0, 1, 2, 3, 4}. This is also a Markov chain on N = {0,1,2,3,4} with the following transition probability matrix P =
[1 0 0 0 0]
[1/2 0 1/2 0 0]
[0 1/2 0 1/2 0]
[0 0 1/2 0 1/2]
[0 0 0 0 1]
(a) Draw a graphical diagram that shows how this chain moves. (b) Is this chain irreducible? Why or why not? (c) Find E(X5 | X3 = 1, X0 = 2).
The random walk with absorbing barriers on the set {0, 1, 2, 3, 4} can be represented as a Markov chain with a transition probability matrix. This chain is irreducible since it is possible to reach any state from any other state. By evaluating the probabilities and the corresponding states, we can find the expected value E(X5 | X3 = 1, X0 = 2) for the given random walk with absorbing barriers.
(a) The graphical diagram representing the random walk with absorbing barriers on {0, 1, 2, 3, 4} can be visualized as a directed graph. Each state is represented by a node, and the arrows indicate the transition probabilities between states according to the given transition probability matrix P.
(b) The chain is irreducible because it is possible to reach any state from any other state. Starting from any state, there is always a positive probability of transitioning to any other state, including the absorbing states (0 and 4). This means that the chain does not have any disjoint subsets of states that are unreachable from one another.
(c) To find E(X5 | X3 = 1, X0 = 2), we condition on the starting state X0 = 2 and the state at time step 3, X3 = 1. Given this condition, we can calculate the expected value of X5, which represents the expected state at time step 5.
To compute this expectation, we can use the Markov property, which states that the future behavior of the chain depends only on its current state. Since X3 = 1 is known, we only need to consider the possible transitions from state 1 to other states according to the transition probability matrix P. By following these transitions, we can calculate the probability of reaching each state at time step 5 and then compute the expected value of X5 accordingly.
By evaluating the probabilities and the corresponding states, we can find the expected value E(X5 | X3 = 1, X0 = 2) for the given random walk with absorbing barriers.

Marie's dad drives an SUV that uses 2.5 litres of fuel for every 20 km driven. He drives to work 20 km each way, 5 days a week. How much fuel does he use to get to work every week?
Answer: 12.5 litres
Step-by-step explanation:
The SUV takes 2.5 litres for every 20 km driven.
The trip to work is 20 km which means that going to work costs Marie's father 2.5 litres every day in fuel.
In a week, there are 5 working days.
The amount of fuel used per week is therefore:
= 2.5 * 5
= 12.5 litres
How many four-digit numbers ABCD have the property that ABCDis equal 26 times BCD?
Note that x1x2...xn represents the n-digit number with digits x1x2...xn.

Answer:
9
Step-by-step explanation:
There are 9 such numbers:
1040, 2080, 3120, 4160, 5200, 6240, 7280, 8320, 9360
_____
For each ABCD, where BCD = x, we want ...
26x = 1000A +x
25x = 1000A
x = 40A
The digit A ranges from 1 to 9 for a 4-digit number. That means there are 9 such numbers. For A=1, for example, x = 40·1 = 40, so the number ABCD is 1040. 26·BCD = 26·040 = 1040 as required.
Answer:
9 is correct but if you are here from caribou math it is 7
Step-by-step explanation:
don't dislike what they said because it is the right formula. 25x = 1000A
you get 1040 2080 3120 4160 5200 6240 7280 8320 9360. But since caribou asks for bcd, b > 0 because its a 3 digit number. from that we can eliminate 1040 and 2080 getting 7

Answer:
true
Step-by-step explanation:
Let w = { 9:,ber) with the standard operations in M22. Which of the following statements is true? W is not a subspace of Mzxz because it does not contain the zero matrix the above is true The 2x2 identity matrix is in W W is a subspace of M2x2. the above is true None of the mentioned
The correct statement is : W is a subspace of M2x2.
TO show that W is a subspace of M2x2, we need to verify that it satisfies the three properties of a subspace:
1. W contains the zero matrix:
The zero matrix in M2x2 is the 2x2 matrix with all entries equal to zero, which is not in W . However , we can see that the matrix {0,0;0,0} can be obtained as the difference between two matrices in W: {9,0;0,0} -{0,ber;0,0} = {0,0;0,0}. So , W does contain the zero matrix.
2. W is closed under addition:
Let A and B be two matrices in W. Then, A ={9,0;0,0} + {0,ber;0,0} and B = {9,0;0,0} + {0,ber;0,0}, which is also in W. Therefore, W is closed under addition.
3. W is closed under scalar multiplication:
Let A be a matrix in W and c be a scalar. Then ,A = {9,0;0,0} + {0,ber;0,0}, and c A = c {9,0;0,0} + c{0,ber;0,0}.
Since {9,0;0,0} and {0,ber;0,0} are both scalar multiples of A, c {9,0;0,0} and c{0,ber;0,0} are also in W . Therefore , W is closed under scalar multiplication.
Since W satisfies all three properties of a subspace, we can conclude that W is a subspace of M2x2.

Container holds 5 red balls, 3 yellow balls and 2 blue balls. A ball is randomly drawn from the container. If the ball is red or blue, it is kept outside the box and a second ball is drawn from the box. If the ball is yellow, it is replaced into the box and a second ball is drawn. Determine the probability that the second ball drawn is yellow.
The probability that the second ball drawn is yellow is 4/9. This is determined by considering the initial probabilities and applying the law of total probability.
Initially, there are a total of 10 balls in the container: 5 red, 3 yellow, and 2 blue. The probability of drawing a yellow ball on the first draw is P(yellow) = 3/10. In this case, the yellow ball is replaced back into the container, so the number of yellow balls remains the same.
If the first ball drawn is not yellow, it means a red or blue ball was drawn. These balls are kept outside the container, so they are not available for the second draw. Now, there are 7 balls remaining in the container: 2 yellow and 5 red (initially there were 5 red and 2 blue, but we only consider the red balls since the blue balls are not relevant for the second draw). The probability of drawing a yellow ball on the second draw, given that the first ball was red or blue, is P(yellow | red or blue) = 2/7.
To find the overall probability that the second ball drawn is yellow, we need to consider the probabilities of the different scenarios and their corresponding probabilities. Since the first ball can either be yellow or not yellow, we can use the law of total probability:
P(second ball is yellow) = P(yellow) * P(yellow on second draw | yellow) + P(not yellow) * P(yellow on second draw | not yellow)
P(second ball is yellow) = (3/10) * (2/10) + (7/10) * (2/7) = 4/9
Therefore, the probability that the second ball drawn is yellow is 4/9.

1. Consider the fixed-point iteration Pk= g(Pk), where g is continuously differentiable on [a, b].
(a) To converge to the fixed point p ∈ (a, b) for any p0 in that interval, the following conditions are required:
i. g(p) = p for p ∈ [a, b].ii. | g'(p) | < 1 for p ∈ (a, b).
(b) For g(x) = 1/3x²-2/3x+4/3, we have two fixed points: 1 and 4.
Let x be sufficiently close to 1:Then, x₁ = g(x₀) = 1/3x₀²-2/3x₀+4/3.
Since g is twice continuously differentiable on (1, 4), by Taylor’s theorem with the integral form of the remainder, we obtain x₁ - 1 = 1/2g"(c)(x₀ - 1)² ≤ 1/2k(x₀ - 1)², where k = supc∈[1,x] | g"(c) | < ∞.
Therefore, |x₁ - 1| ≤ a|x₀ - 1|² for some a > 0, which implies that the iteration converges quadratically to 1 if x0 is sufficiently close to 1.
Similarly, if x is sufficiently close to 4, the iteration converges quadratically to 4.

Since events A and B are mutually exclusive, they cannot occur together. Therefore, the probability of the union of events A and B is equal to the sum of their individual probabilities. P(AUB) = P(A) + P(B) - P(A ∩ B) Where, P(A) = 0.9P(B) = 0.1Since the events are mutually exclusive, P(A ∩ B) = 0Thus,P(AUB) = P(A) + P(B) - P(A ∩ B)= 0.9 + 0.1 - 0= 1 Hence, the value of P(AUB) is 1.

Use the information given to write an equation of the vircle.
Answer:
Step-by-step explanation:
Left hand side.
The left hand side is the general equation that includes the center of the circle.
The center is at -10,-4
(x + 10)^2 + (y + 4)^2 = r^2
Finding the radius.
the radius is found from the given point on the circle
Givens
x1 = -10
x2 = 4
y1 = - 4
y2 = - 2
Equation
r^2 = (y2 - y1)^2 + (x2 - x1)
r^2 = (-2 - - 4)^2 + (4 - - 10)^2
r^2 = 2^2 + 14^2
r^2 = 200
Note:
The graph below shows two things: the first is that the center is at -10,-4The second is that the radius is a little more than 14. The equation of a circle always expresses the radius as r^2
