Answer:

The selling price of the bag is $22.5

Step-by-step explanation:

Buying Price = $25,

Selling Price = ?

Since they sold it at a loss of 10%,

So, they sold it for a price 10% less than the buying price,

or at 90% or 0.9 of the buying price,

so,

Selling Price = (0.9)(25) = $22.5

In summary, if the input graph G(V, E) has a negative weight cycle, there are no solutions to the single-source shortest path problem.

In the single-source shortest path problem, the goal is to find the shortest path from a given source vertex to all other vertices in a graph G(V, E), where V is the set of vertices and E is the set of edges.
If the input graph G(V, E) has a negative weight cycle, then there are no correct solutions to the single-source shortest path problem. This is because the presence of a negative weight cycle allows for a path with decreasing total weight, as you can continually traverse the cycle to reduce the path's weight. As a result, the shortest path is undefined in this case.

The graph of y= 3/8 x + 5 is attached below.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

y= 3/8 x + 5.

Answer:

84330

Step-by-step explanation:

The compound interest formula gives the value of an investment.

 A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.

 110,000 = P(1 +0.019/12)^(12·14)

 P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168

 P ≈ 110,000/1.30446

Answer:

Step-by-step explanation:

Using the algebraic identity

(x + y)³ = x³ + y³ + 3xy(x + y) ← substitute x + y = 4

4³ = x³ + y³ + 12xy , that is

x³ + y³ + 12xy = 64 ( subtract 64 from both sides )

x³ + y³ + 12xy - 64 = 0

Answer:

the answer is zero

Step-by-step explanation:

x^3 + y^3 + 12xy – 64 factorize the polynomial

x^3+y^3-4^3+3(4xy)      64 is 4^3

take x+y-4 as a common factor

Option A

A recursive formula is a formula that defines a sequence of values in terms of its previous values. It provides a way of defining a sequence in a compact form, with each term of the sequence depending on one or more preceding terms.

In mathematics, recursive formulas are often used to define sequences. We can see that in this sequence, the first term is 15 and the common difference is obtained by simple subtraction .

a) the margin of error is 1.675. b) the sample mean is 22.425. c) If the true mean turned out to be 19.45, I would be surprised.

a) The margin of error can be found by taking the difference between the upper limit and the lower limit of the confidence interval and dividing by 2. So, the margin of error is (24.10 - 20.75)/2 = 1.675.

b) The sample mean can be found by taking the average of the upper limit and the lower limit of the confidence interval. So, the sample mean is (24.10 + 20.75)/2 = 22.425.

c) If the true mean turned out to be 19.45, I would be surprised because it falls outside of the 95% confidence interval (20.75, 24.10). This means that there is only a 5% chance that the true mean would fall outside of this interval, so it would be surprising if it did.

Answer:

r(t) = (2t^3 + 3)i + (1/2 e^2t - 2)j + (-cos(t) + 4)k

Step-by-step explanation:

Given r′(t)=6t^2i+e^2tj+sintk and r(0)=3i−2j+k.

To find r(t), we need to integrate r′(t). Integrating each component of r′(t), we get:

r(t) = ∫ r′(t) dt = ∫ (6t^2i+e^2tj+sintk) dt

Integrating the x-component, we get:

∫ 6t^2 dt = 2t^3 + C1

Integrating the y-component, we get:

∫ e^2t dt = 1/2 e^2t + C2

Integrating the z-component, we get:

∫ sin(t) dt = -cos(t) + C3

where C1, C2, and C3 are constants of integration.

Therefore, the solution for r(t) is:

r(t) = (2t^3 + C1)i + (1/2 e^2t + C2)j + (-cos(t) + C3)k

Using the initial condition, r(0)=3i−2j+k, we can find the values of the constants of integration:

r(0) = (2(0)^3 + C1)i + (1/2 e^2(0) + C2)j + (-cos(0) + C3)k

Simplifying, we get:

C1 = 3

C2 = -2

C3 = 4

Therefore, the final solution for r(t) is:

r(t) = (2t^3 + 3)i + (1/2 e^2t - 2)j + (-cos(t) + 4)k

Null hypothesis: The average lifespan of the heaters is equal to or greater than 5 years

Alternative hypothesis: The average lifespan of the heaters is less than 5 years.

In hypothesis testing, the null hypothesis (H0) is a statement that assumes no significant difference between a sample statistic and a population parameter. The alternative hypothesis (Ha) is a statement that contradicts the null hypothesis and asserts that there is a significant difference between the sample statistic and the population parameter.

In this scenario, the company claims that its heaters last less than 5 years. We can express this claim as the alternative hypothesis (Ha), which states that the average lifespan of the heaters is less than 5 years.

On the other hand, the null hypothesis (H0) is a statement that assumes that the average lifespan of the heaters is equal to or greater than 5 years. This is the default assumption until evidence is found to support the alternative hypothesis.

To test these hypotheses, we would collect a sample of heaters and measure their lifespans. We would then calculate the sample mean and compare it to 5 years. If the sample mean is significantly less than 5 years, we would reject the null hypothesis and conclude that the average lifespan of the heaters is less than 5 years.

In summary, the null and alternative hypotheses for this scenario are:

Null hypothesis (H0): The average lifespan of the heaters is equal to or greater than 5 years.

Alternative hypothesis (Ha): The average lifespan of the heaters is less than 5 years

Charge on each sphere is -3.4 × 10⁻⁹ C.

According to Coulomb’s law, the force F between two charged bodies, having charges q1 and q2 and separated by a distance r, is given by

F = (k |q1 q2|) / r² where k is a constant equal to 8.99 × 10^9 N m²/C²

Given:F1 = F2 = 0.0360 N; k = 8.99 × 10^9 N m²/C²; r = 24.3 cm = 0.243 m

Let q be the charge on each sphere.

Because both spheres have equal amounts of charge, the force acting on each sphere is the same.

Hence, F = F1 = F2(q²) = F * r² / (k) = (0.0360 N) * (0.243 m)² / (8.99 × 10^9 N m²/C²)

Charge on each sphere is -3.4 × 10⁻⁹ C.

(a) The probability of it working fine for all three shifts is (0.85)^3 = 61.14%.

(b) The probability that the assembly line works fine throughout the three shifts on Monday is 61.14%. The probability that it works fine on Monday but breaks down during the first shift on Tuesday is 9.17%. The probability of a breakdown on a given day is 38.86%.

(c) The probability of a breakdown on any given day is 1 - 61.14% = 38.86%.

(d) The probability of a breakdown during only one shift on a chosen day is 30.67%.

To calculate the probabilities in this scenario, we will make the following assumptions:

1. The breakdowns are independent events, meaning that the failure of the assembly line during one shift does not affect the probability of failure during another shift.

2. The probability of a breakdown during any given shift is constant at 15%.

(a) To find the probability that the assembly line works fine throughout the three shifts on Monday, we need to find the complement of the event that it breaks down. Since the breakdown probability is 15% for each shift, the probability of it working fine for one shift is 85% (1 - 15%).

(b) To find the probability that the assembly line works fine on Monday but breaks down during the first shift on Tuesday, we multiply the probability of it working fine on Monday (61.14%) by the probability of a breakdown during the first shift on Tuesday (15%). The result is 9.17%.

(c) To find the probability that the assembly line breaks down on a given day, we can subtract the probability of it working fine throughout all three shifts from 1.

(d) To find the probability that the assembly line breaks down during only one shift on a chosen day, we need to consider three cases: breakdown during the first shift only, breakdown during the second shift only, and breakdown during the third shift only. Each of these cases has a probability of 15% * 85% * 85% = 10.22%. Since these cases are mutually exclusive, we can sum their probabilities to get the final result: 10.22% + 10.22% + 10.22% = 30.67%.
