Given the word problem, we can deduce the following information:

1. The total amount is $12.07.

To determine the bills and coins equal to $12.07, we must follow the steps below:

Total = $12.07

So,

We subtract $10 bill since it is the largest bill not larger than the total ($12.07):

$12.07-$10.00= $2.07

We subtract $1.00 since it is the largest bill not larger than the total ($2.07):

$2.07-$1.00= $1.07

We subtract $1.00 since it is the largest bill not larger than the total ($1.07):

$1.07 -$1.00=$0.07

We subtract $0.05(Nickle) since it is the largest bill not larger than the total ($0.07):

$0.07-$0.05= $0.02

We subtract $0.01 (Dime) since it is the largest bill not larger than the total ($0.02):

$0.02-$0.01=$0.01

We subtract $0.01 (Dime) since it is the largest bill not larger than the total ($0.01):

$0.01-$0.01 =0

Therefore, the bills and coins are:

$10 bill =1

$1.00 bill =2

$0.05(Nickle) =1

$0.01 (Dime)=2

The ratio of the number of blue marbles to the number of marbles that are orange or green is 1 : 3.

Ratio is defined as the relationship between two quantities. It can be expressed as a to b, a/b, or a : b.

Let a = total number of blue marbles

b = total number of orange and green marbles

If the total number of blue marbles is 5 and the total number of orange and green marbles are 9 and 6, respectively, then the ratio is 5 to (9 + 6).

Simplify the ratio.

5 : (9 + 6) = 5 : 15 = 1 : 3

Hence, the ratio is 1:3.

Answer:

She will give 78 students to the sixth student.

Step-by-step explanation:

The pattern is adding 6 each time.

Answer: its the 2nd one

Step-by-step explanation:

Given expression is (x-a)³+(x-b)³+(x-c)³-3(x-a)(x-b)(x-c)

We know that,

(a+b+c)³ = a³ + b³ + c³ + 3(a+b)(b+c)(c+a) ------------(i)

Expanding (a+b+c)³, we get

a³ + b³ + c³ + 3(a²b+a²c+b²a+b²c+c²a+c²b) + 6abc

Given a+b+c=3x, substituting in above equation, we get

a³ + b³ + c³ + 9(ab+bc+ca) - 6abc = 27x³ ------------(ii)

Now, expanding given expression, we get

(x-a)³+(x-b)³+(x-c)³-3(x-a)(x-b)(x-c)

x³ - 3x²(a+b+c) + 3x(ab+bc+ca) - (a³+b³+c³-3abc)

Given a+b+c=3x, substituting in above equation, we get

x³ - 9x³ + 9x³ - (a³+b³+c³-3abc)

= -8x³ + (a³+b³+c³+3abc)

Now, using equation (ii), we get

-8x³ + 27x³ - 3(a³+b³+c³-3abc)

= 19x³ + 9abc

Therefore, the given expression is equal to 19x³ + 9abc.

Given a+b+c=3x, we have abc ≤ x³. Hence, the minimum value of 9abc is 9x³.

Substituting this value in above equation, we get

19x³ + 9abc ≥ 19x³ + 9x³ = 28x³

Therefore, the minimum value of given expression is 28x³.

Hence, the correct answer is d) 0.

The given parabolic equation is y = 4x - x² and the point is (1, 3). We are to determine the slope of the tangent line at (1, 3) and then obtain an equation of the tangent line.  we must first calculate the derivative of the given equation.

We can do this by using the power rule of differentiation. The derivative of x² is 2x. So the derivative of y = 4x - x² is dy/dx = 4 - 2x.Since we want to find the slope of the tangent line at (1, 3), we need to substitute x = 1 into the equation we just obtained. dy/dx = 4 - 2x = 4 - 2(1) = 2. Therefore, the slope of the tangent line at (1, 3) is 2.We can now write the equation of the tangent line. We know the slope of the tangent line, m = 2, and we know the point (1, 3).

We can use the point-slope form of the equation of a line to obtain the equation of the tangent line. The point-slope form of the equation of a line is given as: y - y₁ = m(x - x₁)where m is the slope, (x₁, y₁) is a point on the line.Substituting in the values we have, we get:y - 3 = 2(x - 1)We can expand this equation to obtain the slope-intercept form of the equation of the tangent line:y = 2x + 1Therefore, the equation of the tangent line to the parabola y = 4x - x² at the point (1, 3) is y = 2x + 1.

Answer:

Step-by-step explanation: I hypothesize

that I'm going to choose a defective light bulb

the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

To write the system of ordinary differential equations (ODEs) for the transition probabilities Pᵢⱼ(t) of the given continuous-time Markov chain, we need to consider the rate at which the system transitions between different states.

Let Pᵢⱼ(t) represent the probability that the Markov chain is in state j at time t, given that it started in state i at time 0.

The ODEs for the transition probabilities can be written as follows:

dP₁₂(t)/dt = q₁₂ * P₁(t) - q₂₁ * P₂(t)

dP₁₃(t)/dt = q₁₃ * P₁(t) - q₃₁ * P₃(t)

dP₂₁(t)/dt = q₂₁ * P₂(t) - q₁₂ * P₁(t)

dP₂₃(t)/dt = q₂₃ * P₂(t) - q₃₂ * P₃(t)

dP₃₁(t)/dt = q₃₁ * P₃(t) - q₁₃ * P₁(t)

dP₃₂(t)/dt = q₃₂ * P₃(t) - q₂₃ * P₂(t)

where P₁(t), P₂(t), and P₃(t) represent the probabilities of being in states 1, 2, and 3 at time t, respectively.

Now, let's consider the second part of the question: Suppose that the initial state is 1. We want to find the probability that after the first transition, the process X(t) enters state 2.

To calculate this probability, we need to find the transition rate from state 1 to state 2 (q₁₂) and normalize it by the total rate of leaving state 1.

The total rate of leaving state 1 can be calculated as the sum of the rates to transition from state 1 to other states:

total_rate = q₁₂ + q₁₃

Therefore, the probability of transitioning from state 1 to state 2 after the first transition can be calculated as:

P(X(t) enters state 2 after the first transition | X(0) = 1) = q₁₂ / total_rate

In this case, the transition rate q₁₂ is 1, and the total rate q₁₂ + q₁₃ is 1 + 2 = 3.

Therefore, the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

Given:

Two angles are 20 and 130.

Using Angle sum property of triangle

<1 + <2 + <3 = 180

20+ 130 + <3= 180

150 + <3 = 180

<3 = 180- 150

The equation of the plane is -x - 5y - z = 23.

The given plane has a normal vector of (-1,-5,-1). We want our plane to be parallel to this plane, so its normal vector must be parallel to (-1,-5,-1). Let's use (1,5,1) as the normal vector for the plane we want.

To make this vector parallel to (-1,-5,-1), we just need to change the sign of the x-component.

The line r = (-3,-3,-5) + t(-9,2,-1) passes through the point (-3,-3,-5) on the plane we want. So, we can use this point as a point on the plane.

To find an equation of the plane, we can use the point-normal form of the equation of a plane. The equation of the plane is:

(1)(x - (-3)) + (5)(y - (-3)) + (1)(z - (-5)) = 0

Simplifying, we get:

x + 5y + z + 23 = 0

Therefore, an equation of the plane containing the given line, which is parallel to the plane -x-5y-z=23 and has a normal vector of (1,5,1), is x + 5y + z + 23 = 0.

The correct option is A) 5 – 1 ≠ 1 – 5  shows why the commutative property doesn't work under subtraction

The commutative property works for addition and multiplication. It says that when adding or multiplying, you can switch the order of the numbers around and still get the same answer.

For instance, in simple terms, the commutative property of addition states that changing the order of the addends will not change the sum. That is, a + b = b + a.

Similarly, the commutative property of multiplication states that changing the order of the factors will not change the product. That is, a × b = b × a.

However, the commutative property does not work for subtraction and division. You cannot change the order of numbers around and still get the same answer when you're subtracting or dividing. In other words, the order of the numbers matters in these cases.

That is, a - b ≠ b - a; a / b ≠ b / a.Here, the options C and D are not valid since they both represent addition operations, whereas the question demands subtraction. Between options A and B, A represents the subtraction operation and the result for this option is not the same as the result for the reverse subtraction operation which is why A is the right option.

There is no angle (0) in degrees that answers the preceding equation since cos(0) = 3/2 is illogical.

To determine the angles of a right triangle, trigonometric ratios are ratios of the side lengths of the triangle. Sine (sin), cosine (cos), and tangent (tan) are the three fundamental trigonometric ratios, and their definitions are as follows:

Sine: The length of the angle's opposite side divided by the length of the hypotenuse is known as the sine of the angle.

Cosine: The length of the neighbouring side divided by the length of the hypotenuse is the angle's cosine value.

Angle's tangent is determined by dividing the length of the adjacent side by the length of the opposite side.

These ratios can be used to discover missing side lengths in right triangles and other situations with right triangles.
