The solution for b in the ratio is b = -4  + 5(a - 1)/7

From the question, we have the following parameters that can be used in our computation:

The ratio a-1:b+4 is in the ratio 5:7.

Using the above as a guide, we have the following:

a - 1 : b + 4 = 5 : 7

Express the ratio as a fraction

So, we have the following representation

(a - 1)/(b + 4) = 5/7

This gives

7(b + 4) = 5(a - 1)

Divide both sides by 7

b + 4 = 5(a - 1)/7

So, we have

b = -4  + 5(a - 1)/7

Hence, the solution is b = -4  + 5(a - 1)/7

Step-by-step explanation:

1. A water wheel rung’s height as a function of time can be modeled by the equation:

h - 8 = -9 sin6t

(b) Determine the maximum height above the water for a rung.

Given the rung's height modeled by the equation;

h - 8 = -9 sin6t

h(t) = -9sin6t + 8

At maximum height, the velocity of the rung is zero;

dh/dt = 0

dh/dt = -54cos6t

-54cos6t = 0

cos6t = 0/-54

cos6t = 0

6t = cos^-1(0)

6t = 90

t = 90/6

t= 15

Substitute t = 15 into the expression to get the maximum height;

Recall:

h(t) = -9sin6t + 8

h(15) = -9sin6(15) + 8

h(15) = -9sin90 + 8

h(15) = -9(1)+8

h(15) = -9+8

h(15) = -1

hence the maximum height above the water is -1

1. Homeowners insurance policy

2. Pet insurance policy

Step-by-step explanation:

Homeowners' insurance policy is an insurance policy that covers the damages made to an insured place of residence. The insurance company takes care of damages that occur inside, and outside the house. Damaged furnishing as well as accidents that occur within the house are also catered to by the insurance company. The policyholder pays a deductible out of the total amount of money for the claims of damages while the insurance company takes care of the additional cost. So Selina would resort to a homeowners' insurance policy for her house so as to cover the loss in case of a natural calamity.

The Pet insurance policy also takes care of the veterinary costs of pets just in case they fall ill or suffer any other accidents. Selina would buy a pet insurance policy to take care of this potential problem.

Step-by-step explanation:

The patient's belief that the leaf was poison ivy must be the source of the rash (while it actually was harmless unknown to the subjects).

A placebo is something that is identical to the treatment that the treatment group received, except that it does not contain any active components.

The placebo effect is an effect created by a placebo that cannot be attributed to the placebo and is thus caused by the patient's belief in that treatment.

All of the patients developed a rash on their arms where the innocuous leaf was massaged (while being told that the leaf was poison ivy).

On the arm where the poison ivy leaf was applied, 11 of the 13 patients experienced no rash (while being told that the leaf was harmless).

The placebo was the harmless leaf, because a harmless leaf should not contain any active ingredients that could cause harm. The placebo effect is evident since all people believed the leaf was poison ivy (as they were informed) and all received a rash as a result. Because the leaf lacked any active properties that could cause the rash, the source of the rash had to be the patient's belief that the leaf was poison ivy.

So the amount of gain that can be deferred under the installment sale method is $424,879.16.

Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred" in Latin. When a number is expressed as a percentage, it is usually accompanied by the "%" symbol. Percentages are commonly used in many areas of everyday life, such as finance, taxes, and statistics. They are often used to express changes or differences, such as percentage increases or decreases in prices or quantities, or the percentage of people who hold a certain opinion or belong to a certain group.

Here,

To calculate the gain that can be deferred under the installment sale method, we need to first calculate the total gain on the sale. The total gain is equal to the selling price minus the adjusted basis of the property, which is the cost minus the accumulated depreciation.

Selling price = $99,800 cash + $998,000 note = $1,097,800

Adjusted basis = $798,400 - $479,040 = $319,360

Total gain = $1,097,800 - $319,360 = $778,440

To calculate the gain that can be deferred, we need to determine the gross profit percentage. The gross profit percentage is equal to the total gain divided by the selling price:

Gross profit percentage = Total gain / Selling price = $778,440 / $1,097,800 ≈ 0.7097 or 70.97%

Now we can calculate the amount of gain that can be deferred using the formula:

Gain deferred = Gross profit percentage × Payments received

Since the note is due in two years, Skylar will receive half of the payments in 2022 and the other half in 2023. Therefore, the payments received in 2022 are:

$99,800 + ($998,000 / 2) = $598,800

Substituting into the formula, we get:

Gain deferred = 0.7097 × $598,800 = $424,879.16

Answer: I think it's either C or A but, my gut is saying A :)

Step-by-step explanation:

I'll assume you meant f(x) = 3 - 2x and not t(x) = 3 - 2x

\( \frac{3 - 2x}{ \frac{1}{x + 5} } \times 8\)

\(((3 - 2x) \times ( \frac{x + 5}{1} )) \times 8\)

\(((3 - 2x)(x + 5)) \times 8\)

\(( - 2 {x}^{2} - 7x + 15) \times 8\)

\(( \frac{f}{g}) \times 8 = - 16 {x}^{2} - 56x + 120\)

Part A

\(4x^2 -7x-15=0\\\\(4x+5)(x-3)=0\\\\x=-\frac{5}{4}, 3\)

So, the x-intercepts are \(\boxed{\left(-\frac{5}{4}, 0 \right), (3,0)}\)

Part B

The vertex will be a minimum because the coefficient of \(x^2\) is positive.

The x-coordinate of the vertex is \(x=-\frac{-7}{2(4)}=\frac{7}{8}\)

Substituting this back into the function, we get \(f\left(\frac{7}{8} \right)=4\left(\frac{7}{8} \right)^2 -7\left(\frac{7}{8} \right)^2 -15=-\frac{289}{16}\)

So, the coordinates of the vertex are \(\boxed{\left(\frac{7}{8}, -\frac{289}{16} \right)}\)

Part C

Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.

Answer:

Step-by-step explanation:

To find the class limits for the lowest class, you need to know the class interval, which is the difference between the upper class limit and the lower class limit of each class1. You can find the class interval by subtracting the first two class midpoints: 72.5 - 69.5 = 3.

Then, you can find the lower class limit of the lowest class by subtracting half of the class interval from the first class midpoint: 69.5 - 1.5 = 68.

Similarly, you can find the upper class limit of the lowest class by adding half of the class interval to the first class midpoint: 69.5 + 1.5 = 71.

Therefore, the class limits for the lowest class are 68 and 71.

It is important to note that a sample of 5000 responses, while large, may not necessarily be representative of the entire population of students. The sample may have biases or limitations that affect the results of the survey. For example, the survey may have only been distributed to certain groups of students or there may have been a higher response rate from students who are particularly passionate about the issue.
In order to accurately estimate the percent of all students who are outraged, a representative sample of the entire population of students would need to be surveyed, and the survey would need to be designed and administered in a manner that minimizes biases and limitations.

The given limit can be expressed as the definite integral:

∫[0 to 1] 3x^8 dx

To express the limit as a definite integral, we can use the definition of a Riemann sum. Let's consider the function f(x) = x^8.

The given limit can be rewritten as:

lim(n→∞) Σ[i=1 to n] (3i^8 / n^9)

Now, let's express this limit as a definite integral. We can approximate the sum using equal subintervals of width Δx = 1/n. The value of i can be replaced with x = iΔx = i/n. The summation then becomes:

lim(n→∞) Σ[i=1 to n] (3(i/n)^8 / n^9)

This can be further simplified as:

lim(n→∞) (1/n) Σ[i=1 to n] (3(i/n)^8 / n)

Taking the limit as n approaches infinity, the sum can be written as:

lim(n→∞) (1/n) ∑[i=1 to n] (3(i/n)^8 / n) ≈ ∫[0 to 1] 3x^8 dx

The true statement is: "Octave is the name of a particular interval size."

In music theory, an octave refers to the interval between two pitches where the higher pitch has a frequency that is exactly twice that of the lower pitch. It represents a doubling or halving of the frequency. For example, if we start on the note A and move up to the next A, we have traversed an octave.

An interval, on the other hand, refers to the distance between two pitches. It is the numerical representation of the difference in pitch between two notes.

The statement mentioning "interval as the name of a particular octave size" is incorrect because the octave is a specific interval size, not the other way around.

The statement suggesting that "the fifth is a kind of octave" is also incorrect. The fifth is a specific interval that represents the distance of five diatonic scale steps between two pitches.

Lastly, the statement that "a synonym for distance is octave" is not true. While an octave represents a specific interval size, the term "distance" is a more general term that can refer to the measurement between any two pitches, regardless of the specific interval size.

Answer:

Step-by-step explanation: To find out what grade Sally needs to earn on her fifth and last math test to achieve a 90 average, we  use the following steps:

Step 1: Add the total points Sally has received: 80 + 82 + 92 + 98 = 352.

Sally has taken 4 tests so far.

Step 2: Find the total marks required for a 90 average on 5 tests: 90 x 5 = 450.

Step 3: Find the score Sally needs to achieve on her fifth test by subtracting the points earned  from the total required points: 450 - 352 = 98.

Therefore, Sally needs to earn a grade of 98 on her 5th and last test to achieve a 90 average on all five tests this semester.

To determine if a data point is considered an outlier for a data set, we need to calculate the interquartile range (IQR) and use it to define the outlier boundaries. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). The correct option is (B).

We have that Q1 = 9 and Q3 = 17, we can calculate the IQR as follows:

IQR = Q3 - Q1 = 17 - 9 = 8

To identify outliers, we can use the following rule:

- Any data point that is less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR is considered an outlier.

Using this rule, we can evaluate each data point:

A. 27: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

B. 17: This data point is not an outlier because it is equal to the third quartile (Q3).

C. 3: This data point is less than Q1 - 1.5 * IQR = 9 - 1.5 * 8 = -3. It is considered an outlier.

D. 41: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

Therefore, the outliers in the data set are A (27) and D (41).

As for when to use the mean, it is generally recommended to use the mean as a measure of central tendency when the data is symmetric and does not have extreme values.

Therefore, the correct option would be B. When the data is symmetric.
