The general solution is y² - x² cos(y) = C, where C is a constant.
How to solve the differential equation?The given differential equation is a separable equation that can be written as:
y sin(y) dx = x(cos(y)-y sin(y))dy
Integrating both sides, we get:
∫y sin(y) dx = ∫x(cos(y)-y sin(y))dy
Simplifying and integrating, we get:
y(x cos(y) + sin(y)) = C
where C is the constant of integration. Thus, the general solution of the differential equation is given by:
y(x cos(y) + sin(y)) = C
where C is an arbitrary constant.

Consider a male restroom design with minimum plumbing requirements of 12 water closets and 13 lavatories, which one of the following is closest to the minimum space required with considering urinal substitution? Select one: O a. 222 b. 219 c. 237 d. 249
none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.
To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.
The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.
Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:
Minimum space required for water closets = 12 water closets * 30 inches = 360 inches
Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches
Adding these two values together, we get a total minimum space requirement of 672 inches.
Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

How many molecules of SO2 gas would occupy 4.15 L at STP?
Answer:
The number of molecules of SO₂ gas that would occupy a volume of 4.15 L at STP is 1.1153125 × 10²³ molecules
Step-by-step explanation:
The given parameters for the SO₂ gas are;
The volume of the gas = 4.15 L
The condition of the gas = Standard Temperature, and Pressure, STP
The molar volume = The volume occupied by one mole of a gas at STP = 22.4 L
Therefore, we have;
22.4 L = The volume occupied 1 mole of gas
∴ The number of moles in 1 L of gas = 22.4 L/22.4 of gas = 1/22.4 moles of gas
The number of moles in 4.15 L of gas = 4.15 × 1/22.4 moles = 83/448 moles
∴ The number of moles of SO₂ in 4.15 L of SO₂ = 83/448 moles of SO₂.
The number of molecules in one ole of a substance is given by Avogadro's number, \(N_A\) = 6.02 × 10²³ molecules
1 mole of a substance contains 6.02 × 10²³ molecules
83/448 moles of substance contains 83/448 × 6.02 × 10²³ = 1.1153125 × 10²³ molecules
Therefore, the number of molecules in 83/448 moles of SO₂ = 1.1153125 × 10²³ molecules
Therefore, the number of molecules of SO₂ gas that would occupy 4.15 L at STP = 1.1153125 × 10²³ molecules.

Answer: I have no idea my friend but it's real hard Iwish you luck!
Answer:
16.
Step-by-step explanation:
The formula for a triangle is \(\frac{1}{2} * b * h\)
So, we take the triangle we see and but in in the formula.
\(\frac{1}{2} * 2 * 3 = 3.\)
Multiply that by 4, because there are four triangles that size.
\(3 * 4 = 12.\)
Now, we multiply 2 times 2 because that's the surface area for the bottom.
\(2 * 2 = 4.\)
Now, we add the two.
\(12 + 4 = 16.\)

for a related-samples t test, which source of variability attributed to individual differences remains after difference scores are computed?
For a related-samples t test, the source of variability attributed to individual differences that remains after difference scores are computed is typically referred to as residual variance.
This residual variance can be thought of as the unexplained variability that is still present in the data even after accounting for the systematic differences between the two related groups. In order to accurately interpret the results of a related-samples t test, it is important to consider not only the mean difference between the two groups, but also the amount of residual variance that remains in the data. The source of variability attributed to individual differences that remains after difference scores are computed is the "within-subjects variability."
Lastly, we can address the within-subjects variability. Although the difference scores help to reduce the impact of individual differences, there will still be some within-subjects variability. This remaining variability is due to factors such as random error, measurement error, or individual response variability that are not completely accounted for by the difference scores. It is important to consider this variability when interpreting the results of a related-samples t-test.

How to find the slope and the y-intercept?The general linear equation is written as follows:
y = ax + b
Where a is the slope and b is the y-intercept.
On the graph we can see that the y-intercept is y = 6, then we can write the line as:
y = ax + 6

What is the first term of the sequence? To get to the next term, you would. This means that the common difference is There are 20 weeks left in this school year for Sally. If she continues getting breakfast at this rate how much money will she have spent on breakfast by the end of the year?
The requried first term of the sequence is $6.32.
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values
Here,
The amount of money Sally spends on breakfast each week forms an arithmetic sequence.
Let's use the formula for the sum of an arithmetic sequence to find the first term of the sequence. We know that Sally has already spent $31.64, which means that she has made 31.64/4.52 = 7 visits to the breakfast place. So the sum of the first 7 terms of the sequence is:
S₇ = 7/2 * (a₁ + a₇)
We know that a₇ = $4.52, so we can plug this into the formula and simplify
S₇ = 7/2 * (a₁ + 4.52)
a₁ = $6.32
Similarly, all the outcomes can be evaluated,
By the end of the year, Sally will have spent $891.36 on breakfast.
Therefore, the first term of the sequence is $6.32.

Jo owns a gas station in Ponder, Texas. Last year, Jo sold 5,000 gallons of
gasoline at a price of $1 a gallon. Jo's average cost of producing the
5,000-gallons of gasoline was 50 cents a gallon. Did Jo earn a profit? If so,
how much?
Answer:
Jo earned a profit of $2500.
Step-by-step explanation:
Given that:
Selling price of 5000 gallons = $1 per gallon
Total selling price = 1 * 5000 = $5000
Production cost = 50 cents per gallon = $0.5 per gallon
Total production cost = 0.5 * 5000 = $2500
Production cost < Selling cost
Therefore,
Jo earned profit on gasoline.
Profit = Selling cost - Production cost
Profit = 5000 - 2500
Profit = $2500
Hence,
Jo earned a profit of $2500.

Feel free to ask the question.I'll answer the question.Chastity ran a hypothesis test with an alpha level of .01 and her test statistic fell outside of the critical region. what should she do?
The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true). An alpha level of .01 means that there is a 1% chance of making a Type I error.
If Chastity ran a hypothesis test with an alpha level of .01 and her test statistic fell outside of the critical region, it means that the test statistic does not provide enough evidence to reject the null hypothesis.
In this case, Chastity should fail to reject the null hypothesis and accept it as the plausible explanation. This implies that there is not enough evidence to support the alternative hypothesis.
When a test statistic falls outside of the critical region, it indicates that the observed data is not extreme enough to reject the null hypothesis. The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true). An alpha level of .01 means that there is a 1% chance of making a Type I error.
In summary, when Chastity's test statistic falls outside of the critical region, she should fail to reject the null hypothesis and accept it as the plausible explanation. This means that there is not enough evidence to support the alternative hypothesis at the given alpha level of .01.
