Jaime can spend at most $15 today. He buys a drink and a bag of Takis for
$1.59. If gasoline costs $2.89 per gallon, how many gallons of gasoline can
Jaime afford to put in his car?

Answer:

$4871.25

Step-by-step explanation:

You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:

0.88x = 4286.70

You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:

x = 4871.25

Answer:

Step-by-step explanation:

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

We have,

a) To calculate the pressure in the production well at 12 hours of a shut-in, we can use the equation for pressure transient analysis during shut-in periods, known as the pressure buildup equation:

P(t) = Pi + (Q / (4πKh)) * log((0.14ϕμCt(t + Δt)) / (Bo(ΔP + Δt)))

Where:

P(t) = Pressure at time t

Pi = Initial reservoir pressure

Q = Flow rate

K = Permeability

h = Reservoir thickness

ϕ = Porosity

μ = Viscosity

Ct = Total compressibility

t = Shut-in time (12 hours)

Δt = Time since the start of the flow period

Bo = Oil formation volume factor

ΔP = Pressure drop during the flow period

Given:

Pi = 3100 psi

Q = 200 STB/day

K = 45 md

h = 60 ft

ϕ = 15%

μ = 1.2 cp

Ct = 15x10^-6 psi^-1

Bo = 1.3 bbl/STB

t = 12 hours

Δt = 48 hours

ΔP = Pi - P(t=Δt) = Pi - (Q / (4πKh)) * log((0.14ϕμCt(Δt + Δt)) / (Bo(ΔP + Δt)))

Substituting the given values into the equation:

ΔP = 3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15x\(10^{-6}\) * (48 + 48)) / (1.3 * (3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15 x \(10^{-6}\) * (48 + 48)) / (1.3 * (0 + 48))))))

After evaluating the equation, we can find the pressure in the production well at 12 hours of shut-in.

b) Superposition in time is a principle used in pressure transient analysis to analyze and interpret pressure build-up tests.

It involves adding or superimposing the responses of multiple transient tests to simulate the pressure behavior of a reservoir.

The principle of superposition states that the response of a reservoir to a series of pressure changes is the sum of the individual responses to each change.

Superposition allows us to combine the information obtained from multiple tests and obtain a more comprehensive understanding of the reservoir's behavior and properties.

It is a powerful technique used in reservoir engineering to optimize production strategies and make informed decisions regarding reservoir management.

Thus,

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

We first calculate the difference between each pair (y-x) which gives 3, -6, 5, 0, -1. We then calculate the sample mean of these differences which is 1.02.

To compute the test statistic, we need to calculate the standard error of the mean difference, which is the standard deviation of the sample differences divided by the square root of the sample size. Using the sample differences, we can calculate the sample standard deviation to be approximately 3.24. With a sample size of 5, the standard error of the mean difference is approximately 1.45.

The test statistic is calculated as the sample mean difference minus the hypothesized population mean difference divided by the standard error of the mean difference. Substituting the values, we get (1.02 - 0) / 1.45 = 0.70. This is our test statistic.

The interpretation of this result depends on the significance level chosen for the test. If we use a significance level of 0.05, which is a commonly used value, we compare the test statistic to the critical value from the t-distribution with four degrees of freedom (one less than the sample size). Using a t-table, we find the critical value to be approximately 2.78. Since our test statistic of 0.70 is less than the critical value, we fail to reject the null hypothesis that the mean difference is 0.

In summary, to test the claim that the paired sample data come from a population for which the mean difference is Ud=0, we calculated the test statistic using the provided data. The test statistic was 0.70, and using a significance level of 0.05 and a t-distribution with four degrees of freedom, we failed to reject the null hypothesis that the mean difference is 0. This suggests that there is not enough evidence to conclude that the mean difference is different from 0.

In simpler terms, we used the given data to see if there is enough evidence to suggest that the average difference between the paired samples is not 0. By calculating the test statistic and comparing it to a critical value, we determined that we cannot reject the null hypothesis that the mean difference is 0. This means that there is not enough evidence to conclude that the mean difference is different from 0, and we cannot say that there is a significant difference between the paired samples.

We need to find the length of the pendulum, L, if the period is 10 seconds. Rearranging the equation, we get:

L = 32(T/2π)²

Substituting T = 10, we get:

L = 32(10/2π)²

Answer:

4x

Step-by-step explanation:

Simply add 4 and x, and that is 4x.

B. No, because the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The Central Limit Theorem (CLT) is a fundamental concept in statistics that states that as the sample size increases, the sampling distribution of the sample means will approach a normal distribution. However, this is only true if certain conditions are met, one of which is having a large enough sample size.
The CLT states that the sampling distribution of x will be approximately normally distributed if the sample size is large enough (usually greater than 30). If the sample size is small, the sampling distribution may not be normally distributed. In such cases, other statistical techniques like the t-distribution should be used.
Furthermore, the CLT assumes that the population being sampled is not necessarily normally distributed, but it does require that the population has a finite variance. This means that even if the population is not normally distributed, the sampling distribution of x will still be approximately normal if the sample size is large enough.
In conclusion, the answer is B, as the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

Step-by-step explanation:

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

We need 32.265 cubic inches of water to fill the glass completely, including three ice cubes

First, let's find the volume of the glass without any water or ice. We have been given the diameter, which is 3 inches, so we can find the radius by dividing it by 2.

radius (r) = diameter (d) / 2 = 3 / 2 = 1.5 inches

The height of the glass is also given as 6 inches.

To find the volume of the glass, we can use the formula for the volume of a cylinder, which is V = πr²h.

V (volume of glass) = π(1.5)²(6)

= 42.39 cubic inches

Now, we need to find out how much water we need to fill the glass completely, including three ice cubes. Each ice cube has a side length of 1.5 inches, so its volume is given by V = s³, where s is the side length of the cube.

V (volume of one ice cube) = 1.5³

= 3.375 cubic inches

Since there are three ice cubes, the total volume of ice is 3 x 3.375 = 10.125 cubic inches.

To find the volume of water needed, we need to subtract the volume of the ice from the volume of the glass.

V (volume of water needed) = V (volume of glass) - V (volume of ice)

= 42.39 - 10.125

= 32.265 cubic inches

Therefore, we need 32.265 cubic inches of water to fill the glass completely, including three ice cubes
