Chess top uses the periodic inventory system. For the current month, the beginning inventory consisted of 200 units that cost p65 each. During the month, the company made two purchases: 300 units at p68 each and 150 units at p70 each. Chess top also sold 500 units during the month. Using the average cost method, what is the amount of ending inventory?.

Answers

The ending inventory amount is p68,000: (200 x 65) + (300 x 68) + (150 x 70) - (500 x 68) = 68,000.

1. Calculate the total cost of the beginning inventory: 200 units x p65 = p13,000

2. Calculate the total cost of the first purchase: 300 units x p68 = p20,400

3. Calculate the total cost of the second purchase: 150 units x p70 = p10,500

4. Calculate the total cost of the units sold: 500 units x p68 = p34,000

5. Calculate the total cost of the ending inventory amount : (13,000 + 20,400 + 10,500) - 34,000 = p68,000

Given that the system has a relationship between input $ x(t) $ and output $ y(t) $, it can be written as a differential equation as follows: \[ \frac{d^{3} y}{d t^{3}}+2 \frac{d^{2} y}{d t^{2}}+1

Answers

The given system has a relationship between the output $ y(t) $ and its derivatives. It can be represented by the differential equation $\frac{d^3 y}{dt^3} + 2\frac{d^2 y}{dt^2} + 1 = 0$.

The given differential equation represents a third-order linear homogeneous differential equation. It relates the output function $ y(t) $ with its derivatives with respect to time.

The equation states that the third derivative of $ y(t) $ with respect to time, denoted as $\frac{d^3 y}{dt^3}$, plus two times the second derivative of $ y(t) $ with respect to time, denoted as $2\frac{d^2 y}{dt^2}$, plus one, is equal to zero.

This equation describes the dynamics of the system and how the output $ y(t) $ changes over time. The coefficients 2 and 1 determine the relative influence of the second and first derivatives on the system's behavior.

Solving this differential equation involves finding the function $ y(t) $ that satisfies the equation. The solution will depend on the initial conditions or any additional constraints specified for the system.

The true probability of observing a Head based on this simulation is 0.2. What do we expect to happen to the relative frequency of the occurrence of a Head as the number of flips increases from 10 to 10000

Answers

As the number of flips increases from 10 to 10000, we can expect the relative frequency of the occurrence of a Head to become more stable and closer to the true probability of 0.2.

The true probability of observing a Head based on this simulation is 0.2, which means that out of 10 flips, we would expect to see 2 Heads on average. However, as the number of flips increases from 10 to 10000, we would expect the relative frequency of the occurrence of a Head to approach the true probability of 0.2.

This is because of the Law of Large Numbers, which states that as the sample size increases, the sample mean will approach the true mean. In the case of coin flipping, the more flips we make, the closer we will get to the expected proportion of Heads.

For example, if we flip the coin 100 times, we might get 30 Heads and 70 Tails, which is a relative frequency of 0.3. However, if we flip the coin 1000 times, we might get 200 Heads and 800 Tails, which is a relative frequency of 0.2. As we continue to increase the number of flips, the relative frequency will approach the true probability of 0.2.

Therefore, as the number of flips increases from 10 to 10000, we can expect the relative frequency of the occurrence of a Head to become more stable and closer to the true probability of 0.2. This is important to keep in mind when conducting any type of statistical analysis based on coin flipping or other random events.

What are vertices of a polygon?

A vertex is a corner point of a polygon, polyhedron, or other higher-dimensional polytope, formed by the intersection of edges, faces or facets of the object.

The vertices of the polygons are given as B(−2, 2), C(4, −2), D(4, 4) . The polygon is reduced by using a scale factor one fourth. i.e 1/4.

This means that each coordinates of the vertices will be reduced by 4 to give the vertices of the new polygon.

A = (-4,6) , A' = ( -1, 1.5)

B = ( -2,2) B' = ( -0.5, 0.5)

C = ( 4, -2) C' = ( 1, -0.5)

D = ( 4,4) , D' = ( 1, 1)

Therefore the vertices of the new polygon is A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1)

For a ride on a rental scooter, John paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for John's ride was $12.68. For how many minutes did John ride the scooter?

Answers

The required, John rode the scooter for 78 minutes.

What is simplification?

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.

Let's assume that John rode the scooter for x minutes.

The total cost for the ride can be expressed as:

Total Cost = Start-up fee + Cost per minute of the ride

Total Cost = $8 + $0.06*x

We know that the total bill for John's ride was $12.68. Therefore, we can set up an equation:

$12.68 = $8 + $0.06*x

Solving for x, we get:

$0.06*x = $12.68 - $8

$0.06*x = $4.68

x = $4.68 / $0.06

x = 78

Therefore, John rode the scooter for 78 minutes.

Directions: Based on the information given in the following problem, compute the gross pay.

Regular hours worked: 40

Overtime hours worked: 4

Regular rate of pay: $7.80 per hour

Round your answers to two decimal places.

Answers

The gross pay for the given service is $343.2.

What is gross pay?

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages.

Given that, the regular salary of some service is $7.80 per hour, we need to calculate the gross payment with over time hour, which is 4 hours and regular hour of work is 40 hours.

Therefore,

To find, gross payment, we will multiply by 7.80 by 4 and 40, and add both to get the regular salary,

Gross payment = 7.80 × 4 + 7.80 × 40

= 7.80(4+40)

= 7.80 × 44

= 343.2

Hence, the gross pay is $343.2

The representation of a transformation on a coordinate grid does not preserve congruence is b. ( x, y) â†’ ( 7/8 x, 7/8 y) and c. ( x, y) â†’ ( x+6, y-4)

The term coordinate grid refers that pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.

Here we need to find in which of the representation of a transformation on a coordinate grid does not preserve congruence.

According to the concept of transformation, we all know that dilation is the only transformation that does not maintain congruency, as long as the scale factor is not equal to 1.

And we also know that scale factor between 0 and 1 creates a reduction of the figure, and a scale factor that is greater than 1 creates an enlargement of the figure.

Based on these definition, the resulting options are (b) and (c).

You perform a Chi-Square test and obtain a p-value lower than 0.01. What does that mean?

Answers

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Find the number of units x that produces a maximum revenue R.R = 171x2 − 0.06x3x = units

Answers

The number of units x that produces a maximum revenue with the expression given is x = 0.

To find the value of x that maximizes the revenue function R, we can take the derivative of R with respect to x and set it equal to 0. This will give us the critical point of the function.

The derivative of the function R with respect to x is:

R'(x) = 342x - 0.18x²

Setting this equal to 0, we get:

342x - 0.18x² = 0

Solving for x, we find that x = 0 or x = 1900.

However, we need to consider the constraints of the problem to determine which value of x is the optimal solution. If x is a number of units, then x cannot be negative. Therefore, the only valid solution is x = 0.
