Approxiamtely 167 men will be there in a class if the percent of men is 58.6 of the total student.

According to the given question.

Total number of students in the class is 285.

And 58.6 percent of the total students are men.

As we know that, a relative value indicating hundredth parts of any quantity is called a percent.

Therefore,

the total number of men in the class

= 58.6 percent of 285

= (58.6/100) × 285

= 0.586 × 285

= 167.01

Hence, approxiamtely 167 men will be there in a class if the percent of men is 58.6 of the total student.

Answer:

(i)= 45 KPH, (ii) = 251 miles

Step-by-step explanation:

'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.

Then, to see how far a nine hour trip would cover, distance = speed * time =  251 miles.

To solve the equation 4(p-7)=44, the first step is to simplify the left side by distributing the 4 to the parentheses, which yields 4p - 28 = 44 = p=18, meaning that up to 18 pictures can be saved at one time to the photo stream on the cell phone.

Next, isolate the variable term by adding 28 to both sides of the equation, resulting in 4p = 72.

Finally, solve for the variable by dividing both sides of the equation by 4, which gives p = 18.

Therefore, the solution to the equation is p = 18, indicating that 18 pictures can be saved at one time to the photo stream on the cell phone.

To explain in more detail, the equation 4(p-7)=44 can be seen as an algebraic expression that relates the number of pictures that can be saved (p) to a specific constraint, which is that 4 times the difference between p and 7 is equal to 44. The goal of solving the equation is to find the value of p that satisfies this constraint.

To do so, we use the properties of algebraic operations to manipulate the equation in a way that isolates the variable p on one side of the equation. This involves simplifying the left side of the equation using the distributive property, then adding or subtracting terms from both sides of the equation to isolate the variable term.

The final step is to solve for the variable by dividing or multiplying both sides of the equation by a constant, which results in the value of p that satisfies the original constraint. In this case, the solution is p=18, meaning that up to 18 pictures can be saved at one time to the photo stream on the cell phone.

The planned order releases for each item are as follows: A: 20 units in period 1, B: 10 units in period 1, C: 40 units in period 3, D: No planned order release, E: 100 units in period 5, F: 100 units in period 5

To determine the planned order releases for all items, we need to calculate the net requirements for each period based on the given information. We will start with the highest-level item and work our way down the bill of materials.

Item A:

Period 1: Gross requirement of 20 units.

Since A uses lot-for-lot (L4L) as the lot-sizing technique, we release an order for 20 units of A.

Item B:

Item B is a component of A, and each A requires 2 units of B.

We need to calculate the net requirements for B based on the planned order release for A.

Period 1: Gross requirement of 20 units * 2 (requirement multiplier for B) = 40 units.

B has a scheduled receipt of 30 units in period 1.

Net requirement for B in period 1: 40 units - 30 units = 10 units.

Since B also uses L4L as the lot-sizing technique, we release an order for 10 units of B.

Item C:

Item C is a component of A, and each A requires 3 units of C.

We need to calculate the net requirements for C based on the planned order release for A.

Period 1: Gross requirement of 20 units * 3 (requirement multiplier for C) = 60 units.

C has a lead time of two periods, so we need to account for that.

Net requirement for C in period 3: 60 units - 20 units (scheduled receipt for A in period 1) = 40 units.

Since C uses L4L as the lot-sizing technique, we release an order for 40 units of C.

Item D:

Item D is a component of C, and each C requires 1 unit of D.

We need to calculate the net requirements for D based on the planned order release for C.

Period 3: Gross requirement of 40 units * 1 (requirement multiplier for D) = 40 units.

D has a lead time of one period, so we need to account for that.

Net requirement for D in period 4: 40 units - 60 units (scheduled receipt for C in period 3) = -20 units (no requirement).

Since the net requirement is negative, we do not release any planned order for D.

Item E:

Item E is a component of C, and each C requires 1 unit of E.

We need to calculate the net requirements for E based on the planned order release for C.

Period 3: Gross requirement of 40 units * 1 (requirement multiplier for E) = 40 units.

E has a lead time of two periods, so we need to account for that.

Net requirement for E in period 5: 40 units - 0 units (no scheduled receipt for E) = 40 units.

Since E requires a multiple of 100 to be purchased, we release an order for 100 units of E.

Item F:

Item F is a component of B and C, and each B requires 1 unit of F, while each C requires 2 units of F.

We need to calculate the net requirements for F based on the planned order releases for B and C.

Period 1: Gross requirement for B = 10 units * 1 (requirement multiplier for F) = 10 units.

Period 3: Gross requirement for C = 40 units * 2 (requirement multiplier for F) = 80 units.

F has a lead time of two periods, so we need to account for that.

Net requirement for F in period 5: 10 units + 80 units - 0 units (no scheduled receipt for F) = 90 units.

Since F requires a multiple of 100 to be purchased, we release an order for 100 units of F.

Using the z-distribution, as we are working with a proportion, it is found that the buyers need a sample of 1505.

A confidence interval of proportions is given by:

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which:

The margin of error is given by:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In this problem, we have a 98% confidence level, hence\(\alpha = 0.98\), z is the value of Z that has a p-value of \(\frac{1+0.98}{2} = 0.99\), so the critical value is z = 2.327.

There is no estimate of the percentage, hence \(\pi = 0.5\), and the margin of error is of M = 0.03, hence we solve for n to find the desired sample size.

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.03 = 2.327\sqrt{\frac{0.5(0.5)}{n}}\)

\(0.03\sqrt{n} = 2.327(0.5)\)

\(\sqrt{n} = \frac{2.327(0.5)}{0.03}\)

\((\sqrt{n})^2 = \left(\frac{2.327(0.5)}{0.03}\right)^2\)

The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is 0.653, which is equivalent to 65.3%.

It is important to note that this value is based on a random sample of respondents and may not necessarily represent the true proportion of the entire population of Vermont who exercise regularly.

To find the sample proportion of people from Vermont who exercised for at least 30 minutes a day, 3 days a week, follow these steps:

1. Convert the given percentage (65.3%) to a decimal by dividing by 100: 65.3 / 100 = 0.653
2. Multiply the decimal by the number of participants in the random sample (100 respondents): 0.653 * 100 = 65.3
3. Round the result to the nearest whole number to find the number of participants who exercised: 65.3 ≈ 65
4. Divide the number of participants who exercised (65) by the total number of participants in the random sample (100): 65 / 100 = 0.65

This means that out of the 100 participants sampled from Vermont, 65.3 of them answered "yes" to the question of whether they had exercised for more than 30 minutes a day for three days out of the week.

The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day, 3 days a week is 0.65 or 65%.

The simplified expression for (f ∘ g)(x) is 2 + x (option d).

To find and simplify (f ∘ g)(x), we need to substitute the expression for g(x) into f(x) and simplify.

Given:

f(x) = log₃(9x)

g(x) = \(3^x\)

Substituting g(x) into f(x):

(f ∘ g)(x) = f(g(x)) = log₃\((9 * 3^x)\)

Now, we simplify the expression:

log₃\((9 * 3^x)\) = log₃(9) + log₃\((3^x)\)

Since logₓ(a * b) = logₓ(a) + logₓ(b), we have:

log₃(9) + log₃\((3^x)\) = log₃\((3^2)\) + x

Using the property logₓ\((x^a)\) = a * logₓ(x), we get:

log₃\((3^2)\) + x = 2 * log₃(3) + x

Since logₓ\((x^a)\) = a, where x is the base, we have:

2 * log₃(3) + x = 2 + x

Therefore, (f ∘ g)(x) simplifies to:

(f ∘ g)(x) = 2 + x

To verify if χ is an eigenstate of Sy, we need to calculate the result of Syχ. Syχ is given by;

Syχ= 2ℏ​(0 i −i 0)2 ​1

​(1 i)​=2ℏ​(0−1 i0)2 ​1

​(1 i)​=2ℏ​(−i i)2 ​1

​(1 i)​=2ℏ​(−i+1)2 ​1

​(1 i)​=2ℏ​(−i+1)2 ​1

​(1 i)​= (−2ℏi+2ℏ)2 ​1

​(1 i)​= 2ℏ(1−i)2 ​1

​(1 i)​=2ℏ​(1−i)(1 i)2 ​1

​=2ℏ​(1−i)2 ​1​

= 2ℏ ​(1 − 2i) 2 ​1

​Therefore, Syχ = 2ℏ ​(1 − 2i) 2 ​1​

We know that for any eigenstate, Syχ = λχ Where λ is the corresponding eigenvalue.

From the above calculation, we can say that 2ℏ ​(1 − 2i) 2 ​1​is an eigenvalue of Sy. The corresponding eigenvalue can be found by equating the two.

2ℏ ​(1 − 2i) 2 ​1​= λ 2 ​1​λ = 2ℏ (1 − 2i)

Answer:

(x + 6)(x + 7)

Step-by-step explanation:

To factor the trinomial x^2 + 13x + 42, we need to find two numbers that multiply to 42 and add up to 13.

One way to do this is to list all the pairs of factors of 42 and see which pair adds up to 13:

1, 42 -> 1 + 42 = 43

2, 21 -> 2 + 21 = 23

3, 14 -> 3 + 14 = 17

6, 7 -> 6 + 7 = 13

So the pair of factors that we want is 6 and 7. We can use these numbers to rewrite the middle term of the trinomial:

x^2 + 13x + 42 = x^2 + 6x + 7x + 42

Next, we can group the first two terms and the last two terms:

x^2 + 6x + 7x + 42 = (x^2 + 6x) + (7x + 42)

Now, we can factor out the greatest common factor from each group:

x(x + 6) + 7(x + 6)

Notice that we have a common factor of (x + 6) in both terms. We can factor this out:

(x + 6)(x + 7)

Answer: The domain would be all real numbers.

Step-by-step explanation:

This is not a piecewise function, so it means that the domain, which means all possible x values, is all real numbers, not imaginary.

When x³-2x^2-15x is factored completely, one of the factors is x-5.

To factor the expression, we can use the method of grouping. We can rewrite the expression as follows:

x³-2x^2-15x = (x³-2x^2) - 15x

We can then factor the first two terms using the difference of squares:

x³-2x^2-15x = (x-2)(x^2+2x) - 15x

We can then factor the last term using the difference of squares:

x³-2x^2-15x = (x-2)(x^2+2x) - (5)(3x)

Then, we can combine the two factors to get the final answer:

x³-2x^2-15x = (x-5)(x^2+2x-3x)

The final factorization is:

x³-2x^2-15x = (x-5)(x^2-x)

So, the correct answer is (A) x-5.

3. With the income tax rates, the number of hours that must be worked to pay the rent each month is 85 hours.

4. The minimum realized income value is obtained as $1002.09 per month.

What is income tax?

A tax levied against people or organizations (taxpayers) in relation to their income or profits is known as an income tax. (commonly called taxable income). Tax rates multiplied by taxable income are typically used to calculate income taxes. Tax rates might change depending on the taxpayer's attributes and source of income.

To determine how many hours must be worked to pay the monthly rent of $875, we need to calculate the amount of net pay earned per hour after taxes and deductions.

The net pay earned per hour can be calculated as -

Net pay per hour = Hourly wage - (Hourly wage × Total tax rate)

where Total tax rate is the sum of all the tax deductions, i.e., FICA of 7.65%, federal tax withholding of 10%, and state tax withholding of 7.5%.

Total tax rate = 0.0765 + 0.1 + 0.075 = 0.2515

Net pay per hour = $13.75 - ($13.75 × 0.2515) = $10.26 (rounded to two decimal places)

To find how many hours must be worked to pay the rent, we can divide the monthly rent by the net pay per hour -

Hours worked to pay rent = Monthly rent / Net pay per hour

Hours worked to pay rent = $875 / $10.26

Hours worked to pay rent = 85.14

So, it would take approximately 85.14 hours (rounded up to the nearest whole number) to earn enough money to pay the rent for the month.

Therefore, the answer is 85 hours.

Assuming the same tax deductions as in the previous question (FICA of 7.65%, federal tax withholding of 10%, and state tax withholding of 7.5%), we can find the minimum realized income needed to pay the rent by using the following formula -

Minimum realized income = Rent / (1 - Total tax rate)

where Total tax rate = FICA + federal tax withholding + state tax withholding.

Plugging in the given values, we get -

Total tax rate = 0.0765 + 0.1 + 0.075 = 0.2515

Minimum realized income = 750 / (1 - 0.2515) = 1002.09

Therefore, the minimum realized income needed to pay the rent is $1002.09 per month.
