The inequality that represents the the possible numbers of x pairs of socks you can buy when you buy 2 pairs of sneakers, using a system of equations, is of:

y ≤ 7.

A system of equations is a set of equations involving multiple variables that are related, and then operations are made to solve these equations and identify the numeric value of each variable in the context of the problem from which the system was built.

For this problem, the variables are given as follows:

You have a $250 card to use at a sporting goods store. Each pair of sneakers is worth $80 and a pair of socks costs $12, hence the inequality regarding the total spending is:

80x + 12y ≤ 250.

When two pairs of sneakers are bought, we have that:

x = 2.

Hence the inequality regarding how many pairs of socks can be bought is:

80(2) + 12y ≤ 250.

160 + 12y ≤ 250.

12y ≤ 90

y ≤ 90/12

y ≤ 7. (rounded down, as you can buy 7 pairs of socks but not 8).

The cost of a pair of socks is of $12.

I will not give you an answer, but I will give you how too get the equation started.

Step-by-step explanation:

set up an equation using:

x= amount invested at 3%

7800 - x = amount invested at 12%

.03(x) + .12(7800 - x) = 504

.03x +936 - .12x = 504

Step-by-step explanation:

The power of the test is low and not sufficient to detect a significant difference between the two treatments with the given sample size of 35.

To calculate the expected power of the test, we need to consider the survival rates, the significance level, and the sample size. Let's follow these steps:

Determine the proportions
Old treatment survival rate (p1) = 0.75
New treatment survival rate (p2) = 0.85

Determine the significance level
Two-sided significant difference level (α) = 0.05

Calculate the pooled proportion
Pooled proportion (p) = (p1 + p2) / 2 = (0.75 + 0.85) / 2 = 0.80

Calculate the standard error
Standard error (SE) = √(p × (1 - p) × (1/n1 + 1/n2)) = √(0.80 × (1 - 0.80) × (1/35 + 1/35)) ≈ 0.065

Calculate the test statistic (z)
z = (p2 - p1) / SE = (0.85 - 0.75) / 0.065 ≈ 1.54

Find the critical value for the two-sided significant difference at the 5% level
z_critical = 1.96 (from a standard normal distribution table)

Calculate the power of the test
In this case, since the test statistic is smaller than the critical value (1.54 < 1.96), we cannot reject the null hypothesis at the 5% significance level.

The sum Jose wants to compute is

3 + 6 + 9 + … + 993 + 996 + 999

but since each number is a multiple of 3, he can remove a factor of 3 from eac term:

3 (1 + 2 + 3 + … + 331 + 332 + 333)

Then it's clear that the sum contains 333 terms.

Let S be the value of the sum of the first 333 natural numbers:

S = 1 + 2 + 3 + … + 331 + 332 + 333

Reversing the order of terms has no effect on this value:

S = 333 + 332 + 331 + … + 3 + 2 + 1

Now notice that terms in the same position sum to 334:

1 + 333 = 334

2 + 332 = 334

3 + 331 = 334

and so on. This means that if we pair up terms in the positions and add them up, all we are doing is doubling the value of S on the left side, and adding up 333 copies of 334 on the right side:

2S = 334 + 334 + … + 334 + 334

2S = 333 × 334

Solve for S :

S = 333 × 334 / 2 = 55,611

Then the sum Jose is considering is 3 times this value,

The revenue function R(x) is obtained as R(x) = (-0.9/2)x² + 35x.

a) In order to transform ¹ 2x+4 dx into a basic integral, let:

u = 2x + 4,

du = 2 dx.

Then the integral becomes:¹ 2x+4 dx = ¹ u (1/2) du

b) Performing the substitution yields the integral:

¹ u (1/2) du = (1/2) ¹ u du

c) Once we integrate and substitute, the final answer in terms of x is:

(1/2) u² + C

= (1/2) (2x + 4)² + C

= x² + 4x + 2 + C.

Therefore, the indefinite integral of 2x + 4 is x² + 4x + 2 + C.

If the marginal revenue for ski gloves is MR = -0.9x + 35 and R(0) = 0, the revenue function R(x) can be found using the following steps:

Step 1: Integrate the marginal revenue function MR(x) to get the total revenue function TR(x):

TR(x) = ∫MR(x) dx

= ∫(-0.9x + 35) dx

= (-0.9/2)x² + 35x + C

Step 2: Use the initial condition R(0) = 0 to find the constant C:

R(0) = (-0.9/2)(0)² + 35(0) + C = 0

C = 0

Therefore, the revenue function R(x) is:

Step-by-step explanation:

Let's assume the basic fee for water is $X per unit and the tariff for consumption is 5% increase per unit. VAT (Value Added Tax) is calculated at a rate of Y% on the total cost, including the basic fee and the tariff.

Given that the consumption is 15 units, the total cost for the consumption of 15 units of water without VAT can be calculated as:

Total cost without VAT = Basic fee + (Tariff rate * Number of units)

Tariff rate = 5% increase per unit, so it would be 1 + 5% = 1.05

Total cost without VAT = X + (1.05 * 15) = X + 15.75

Now, let's assume the VAT rate is Z%. The total cost including VAT can be calculated as:

Total cost including VAT = Total cost without VAT + (VAT rate * Total cost without VAT)

Total cost including VAT = (X + 15.75) + (Z% * (X + 15.75))

To calculate the amount by which the total cost, including VAT, for the consumption of 15 units of water will increase, we need to subtract the initial cost from the increased cost:

Increased cost = Total cost including VAT - Total cost without VAT

Increased cost = [(X + 15.75) + (Z% * (X + 15.75))] - (X + 15.75)

Simplifying, we get:

Increased cost = Z% * (X + 15.75)

So, the amount by which the total cost, including VAT, for the consumption of 15 units of water will increase depends on the value of Z% (the VAT rate) and X (the initial basic fee for water). Once we have these values, we can calculate the increased cost accordingly.

To test a second condition only after the result of the first condition is known, If statements can be used. The "else if" statement can be used to test a second condition only after the result of the first condition is known.

If statements are programming language statements that enable a computer program to make a decision on whether or not to perform a certain code block. The code within the conditional statement will only execute if the conditional expression is true. If there is a need to test a second condition only after the result of the first condition is known, one can use If statements as it allows the computer program to make decisions. An If statement checks a condition, and if the condition is true, it carries out a block of code otherwise, it skips the block and proceeds to the next block of code. A code block to be executed if the condition is true can be specified with the if statement. The conditional statement in an if statement can be used to compare two values. The two values must be of the same data type in order to be compared.

The "else if" statement can be used to test a second condition only after the result of the first condition is known.

In programming, the "if" statement is used to test a condition and execute a block of code if the condition is true. However, when we want to test multiple conditions sequentially, the "else if" statement is used. It allows us to specify an additional condition to test if the previous condition(s) evaluated to false.

Here's an example of how the "if" and "else if" statements can be used:

if (condition1) {

   // code to execute if condition1 is true

} else if (condition2) {

   // code to execute if condition1 is false and condition2 is true

} else {

   // code to execute if both condition1 and condition2 are false

}

In this case, the "else if" statement allows us to test the second condition only if the first condition is false. It provides a way to handle multiple scenarios or options based on different combinations of conditions.

The null hypothesis for the data will be 21.62 and the alternate hypothesis is 2.02 for the p-value for the data is 0.2253 .

The charge at which anything happens is referred to as the velocity at which it happens.

The required details for mean rate :

(a) H0: µ = 21.62

Ha: µ ≠ 21.62

(b) t = -1.231

p-value = 0.2253

(c) Stop rejecting H0 right now. No longer significantly different from the domestic water tariff in Tulsa, the suggested household water charge per five CCF for the entire USA.

(d) H0: µ = 21.62

Ha: µ ≠ 21.62

t = -1.231

check statistic ≥ 2.020

Don't dismiss H0 any longer. The suggested five CCF residential water charge for the entirety of the USA is no longer significantly different from the five CCF residential water tariff in Tulsa.

The P-value is higher at 0.05, the level of significance. The impact in this instance is negligible. The attempt to reject the null hypothesis failed.

The conclusion is that there is insufficient statistical support to determine whether other American cities have a different mortality rate than Tulsa.

The crucial values for t at this level of significance are t=2.019.

Given that the statistic t = -1.15 is inside the acceptance range in this case, the null hypothesis is not disproved.

2 pounds is equivalent to approximately 9 cups. both are unit of measurement of weight.

There are several ways to convert weight measurements, such as pounds, to volume measurements, such as cups. However, it is important to note that the conversion will vary depending on the substance being measured.

In general, one pound of a dry ingredient such as flour or sugar is equivalent to approximately 2 cups. Therefore, 2 pounds is equivalent to approximately 4 cups. However, this conversion may vary depending on the substance and the measurement method.If you are measuring a liquid, 1 pound is equivalent to 16 ounces.

1 cup is equivalent to 8 ounces. Therefore 2 pounds is equivalent to 32 ounces or 4 cups.It's also important to note that weight measurements are more precise than volume measurements, as volume measurement can be affected by factors such as how tightly packed the ingredient is, so it is best to use weight measurements for accurate measurements.

To expand its manufacturing capacity with a $20 million investment in new machinery while maintaining its current capital structure and dividend policy, Gardial GreenLights must seek external equity of $8 million.

The capital structure of Gardial GreenLights is characterized by a 50% debt-to-total-assets ratio. Since the company plans to maintain this ratio, the remaining 50% of the assets must be financed through equity. The investment in new machinery is $20 million, which represents 50% of the total assets needed for expansion. Therefore, the total assets required for expansion would be $40 million (20 million divided by 0.5). To determine the amount of external equity needed, we subtract the company's existing equity from the total assets required. Given that the company's dividend policy entails distributing 25% of the year's net income, we can calculate the retained earnings. This year's net income was $8 million, and 25% of that ($2 million) would be distributed as dividends. Therefore, the retained earnings amount to $6 million ($8 million - $2 million). Since external equity is the difference between the total assets required and retained earnings, Gardial GreenLights must seek external equity of $34 million ($40 million - $6 million) to finance its expansion plans.

Explanation:

Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)

So 900-360

Answer:

360

Step-by-step explanation:

So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.        

Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.

And you can check it by multiplying 900 x .40 which would be 360

The solution of the differential equation by undetermined coefficients y(x) is c1 cos(√6x) + c2 sin(√6x) − 49/3 x²e⁶ˣ

The differential equation given is a second-order linear homogeneous differential equation with constant coefficients, which has the form:

y'' + ay' + by = f(x)

where a and b are constants and f(x) is a non-homogeneous function. To solve this equation, we need to find a particular solution for the non-homogeneous part and add it to the general solution of the homogeneous part.

The method of undetermined coefficients is used to find the particular solution for non-homogeneous differential equations. In this method, we assume the particular solution has the same form as the non-homogeneous function, with unknown coefficients that need to be determined.

In this case, the non-homogeneous function is −294x²e⁶ˣ. We assume that the particular solution has the form:

y_p(x) = Ax²e⁶ˣ

where A is the unknown coefficient that we need to determine.

Now, we find the first and second derivatives of y_p(x):

y'_p(x) = 2Axe⁶ˣ + 6Ax²e⁶ˣ

y''_p(x) = 12Axe⁶ˣ + 12Ax²e⁶ˣ

Substituting these derivatives and the assumed particular solution into the differential equation, we get:

(12Axe⁶ˣ + 12Ax²e⁶ˣ) + 6(Ax²e⁶ˣ) = −294x²e⁶ˣ

Simplifying the equation, we get:

18Ax²e⁶ˣ = −294x²e⁶ˣ

Solving for A, we get:

A = −49/3

Therefore, the particular solution is:

y_p(x) = −49/3 x²e⁶ˣ

Now, we need to find the general solution for the homogeneous part of the differential equation:

y'' + 6y = 0

The characteristic equation is:

r² + 6 = 0

Solving for r, we get:

r = ±√6i

Therefore, the general solution for the homogeneous part is:

y_h(x) = c1 cos(√6x) + c2 sin(√6x)

where c1 and c2 are constants.

Finally, the general solution for the non-homogeneous differential equation is the sum of the particular and homogeneous solutions:

y(x) = y_h(x) + y_p(x)

y(x) = c1 cos(√6x) + c2 sin(√6x) − 49/3 x²e⁶ˣ

where c1 and c2 are determined by the initial conditions, if given.
