How many solutions does this equation have? 3y = –4 + 2y

Given:

A jet flies 175 miles in 7 minutes.

To find:

How far will the jet fly in 85 minutes?

Solution:

According to the given information,

Distance covered by the jet in 7 minutes = 175 miles

Using this, we get

Distance covered by the jet in 1 minutes = \(\dfrac{175}{7}\) miles

Distance covered by the jet in 1 minutes = \(25\) miles

Now,

Distance covered by the jet in 85 minutes = \(85\times 25\) miles

Distance covered by the jet in 85 minutes = \(2125\) miles

Therefore, the jet flies 2125 miles in 85 minutes.

Answer:

528

Step-by-step explanation:

We are given the following sequence:

31,41,51,61,71,81,91,101

Count the terms and see that there are 8 terms total.

If you notice, each terms add up by 10.

31+10 = 41

41+10 = 51

51+10 = 61

Therefore, this is an arithmetic sequence with 10 as common difference.

To find the sum of 8 sequences, we will be using the following formula.

\( \displaystyle \large{S_n = \frac{1}{2} n(a_1 + a_n)}\)

We know that:

Substitute the following in the sum formula.

\( \displaystyle \large{S_8 = \frac{1}{2} (8)(31+ 101)} \\ \displaystyle \large{S_8 = 4(132)} \\ \displaystyle \large{S_8 = 528}\)

Therefore, the sum of all 8 sequences is 528.

Tax Liability = Tax on 10% Bracket + Tax on 12% Bracket + Tax on 22% Bracket + Tax on 24% Bracket

To determine Fred and Ginger's tax liability for 2021, we will use the tax formula and consider the various items of income and expenses provided. Let's go through each category step by step:

Calculate Adjusted Gross Income (AGI):

AGI = (Fred's Salary) + (Ginger's Salary) + (Interest Income on State of Arizona Bonds) + (Interest Income on US Treasury Bonds) + (Qualified Cash Dividends) + (Share of Hollywood Corporation S Corporation Income) + (Short-term Capital Gains) + (15% Long-term Capital Gains) + (Share of RKO Partnership Loss) + (Life Insurance Proceeds)

AGI = $110,000 + $125,000 + $3,000 + $8,000 + $6,000 + $30,000 + $5,000 + $30,000 + (-$10,000) + $150,000

AGI = $547,000

Determine Itemized Deductions:

Itemized Deductions = (Home Mortgage Interest) + (Home Equity Loan Interest) + (Vacation Home Loan Interest) + (Car Loan Interest) + (Home Property Taxes) + (Vacation Home Property Taxes) + (Car Tags) + (Arizona Sales Taxes Paid) + (Medical Insurance Premiums) + (Unreimbursed Medical Bills) + (Charitable Contributions)

Itemized Deductions = $18,000 + $6,000 + $8,400 + $3,000 + $6,000 + $1,800 + $950 + $6,500 + $12,000 + $10,000 + $12,000

Itemized Deductions = $95,650

Calculate Taxable Income:

Taxable Income = AGI - Itemized Deductions

Taxable Income = $547,000 - $95,650

Taxable Income = $451,350

Determine Tax Liability using the Tax Table or Tax Formula:

Based on the provided information, we'll assume Fred and Ginger are filing as Married Filing Jointly for 2021. Using the tax brackets and rates for that filing status, we can calculate their tax liability. Please note that the tax rates and brackets are subject to change, so it's important to refer to the most recent tax regulations.

Tax Liability = (Tax on 10% Bracket) + (Tax on 12% Bracket) + (Tax on 22% Bracket) + (Tax on 24% Bracket)

The taxable income falls into multiple brackets, so we'll calculate the tax liability for each bracket separately:

Tax on 10% Bracket: $0 - $19,900 = $0

Tax on 12% Bracket: $19,901 - $81,050 = ($81,050 - $19,900) * 0.12

Tax on 22% Bracket: $81,051 - $172,750 = ($172,750 - $81,050) * 0.22

Tax on 24% Bracket: $172,751 - $451,350 = ($451,350 - $172,750) * 0.24

Calculate the total tax liability:

Tax Liability = Tax on 10% Bracket + Tax on 12% Bracket + Tax on 22% Bracket + Tax on 24% Bracket

explanation: 4-1/-3-(-4)

To calculate the percent change in renewable energy investment in the US from 2005 to 2018, you can use the following formula:

Percent change = ((Final value - Initial value) / Initial value) * 100%

In this case, the initial value is $11.4 billion in 2005 and the final value is $46.5 billion in 2018. Plugging these values into the formula, we get:

Percent change = (($46.5 billion - $11.4 billion) / $11.4 billion) * 100%

= ($35.1 billion / $11.4 billion) * 100%

= 3.085 * 100%

= 308.5%

So, the percent change in renewable energy investment in the US from 2005 to 2018 was 308.5%, a substantial increase over the 13-year period.

Answer: A rotation about 270 degrees CW about the origin and 90 CCW about the orgin.

Step-by-step explanation:  Using the rules of 90 degrees Counterclockwise

(x,y)⇒( -y,x)

D is 3,2 then it  goes to  -2,3 which were A is

E is 3,7 then it goes to -7,3 which C is at

F is 10,5 then it goes to -5,10 where B at.

Also it 270 CW because 270 CW is the same as 90 CCW.

The expected value (EV) of T1 is 1/λ, and the variance (Var) of T1 is 1/λ^2, where λ is the rate parameter of the exponential distribution.

Given that T1 is exponentially distributed with a probability density function fr(t) = \(7e^(-4t),\) we can calculate the expected value (EV) and variance (Var) of T1.

To find the EV, we integrate the product of t and fr(t) over the range of possible values of T1

EV[T1] = \(∫ t * fr(t) dt = ∫ t * 7e^(-4t) dt\)

Using integration by parts, we can find that EV[T1] =\([t * (-7/4)e^(-4t)] - ∫ (-7/4)e^(-4t) dt\)

Simplifying further, EV[T1] = [-7t/4 * e^(-4t)] - (7/16) * e^(-4t) + C

Evaluating this expression over the range of possible values of T1 (from 0 to infinity), we find that EV[T1] = 4/7.

To calculate the variance, we can use the formula Var[T1] =\(E[(T1 - EV[T1])^2].\)

Varhttps://brainly.com/question/30034780?referrer=searchResults

Plugging in the value of EV[T1], we have Var[T1] = \(∫ (t - 4/7)^2 * 7e^(-4t) dt\)

Simplifying and evaluating this integral, Var[T1] = 8/49.

Therefore, the expected value of T1 is 4/7 and the variance of T1 is 8/49.

From the given information provided, the means of x₁, x₂,  and x₃ are 158.28, 41.3, and 43.75 respectively.

a. Handle the missing values using omission strategy:

The omission strategy involves removing any observation with missing values.

The resulting table after the omission strategy is as follows:

Obs x₁ x₂ x₃

1 248 3.5 3.8

A scientific hypothesis is a proposed explanation or prediction based on limited evidence or prior knowledge, which is subject to further investigation and testing.

A guess is a speculative, unsupported statement without any logical basis, whereas a hypothesis is an educated assumption derived from existing knowledge, observations, or theories. Unlike a guess, a hypothesis is testable and can be supported or refuted by evidence gathered through scientific methods.

Scientists need a hypothesis to provide a framework for their research and guide their investigations. It helps them define the specific question they want to answer and provides a starting point for designing experiments or making observations. By formulating a hypothesis, scientists can systematically evaluate and analyze data, ultimately leading to a deeper understanding of the phenomenon under investigation.

There are indeed scientific hypotheses that cannot be directly tested or proven due to practical or ethical constraints. For example, hypotheses related to historical events that occurred in the distant past may not have accessible evidence for direct testing. Additionally, some questions related to consciousness, subjective experiences, or philosophical concepts may lie beyond the scope of scientific inquiry, as they may not be objectively measurable or observable.

While science has its limitations, it is a powerful tool for investigating and understanding the natural world. However, there are questions that fall outside the realm of scientific inquiry and require other methods of investigation, such as philosophical or ethical considerations.

60° because it's an equilateral triangle

Answer:

No, Anthony is not correct.

Step-by-step explanation:

K is at (-4, 8), L is at (-7, 4), M is at (-2, 1)

KL

\( \sqrt{ {( - 4 - ( - 7))}^{2} + {(8 - 4)}^{2} } \)

\( \sqrt{ {3}^{2} + {4}^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5\)

LM

\( \sqrt{ {( - 7 - ( - 2))}^{2} + {(4 - 1)}^{2} } \)

\( \sqrt{ {( - 5)}^{2} + {3}^{2} } = \sqrt{25 + 9} = \sqrt{34} \)

KM

\( \sqrt{ {( - 4 - ( - 2))}^{2} + {(8 - 1)}^{2} } \)

\( \sqrt{ {( - 2)}^{2} + {7}^{2} } = \sqrt{4 + 49} = \sqrt{53} \)

From these, it follows that KLM is not an isoceles triangle.

This means that a ⊕ b = (a − b) ∪ (b − a), as desired.

Why will be show that a ⊕ b = (a − b) ∪ (b − a)?

we need to demonstrate that any element in either set is also in the other set.

First, let's consider (a − b) ∪ (b − a). This set includes any element that is in a but not in b, or in b but not in a.

Now, let's look at a ⊕ b. This set includes any element that is in a or b, but not in both.

To show that these sets are equal, we need to show that any element that is in (a − b) ∪ (b − a) is also in a ⊕ b, and vice versa.

First, let's consider an element x that is in (a − b). This means that x is in a but not in b. Therefore, x is also in a ⊕ b, since it is in a but not in both a and b.

Next, let's consider an element y that is in (b − a). This means that y is in b but not in a. Again, y is also in a ⊕ b, since it is in b but not in both a and b.

Therefore, we have shown that any element in (a − b) ∪ (b − a) is also in a ⊕ b, and vice versa. This means that a ⊕ b = (a − b) ∪ (b − a), as desired.

Dilation and rotation will not produce a congruent triangle

What is rotation ?

The rotation of a point with regard to the origin is described by the rotation formula. To get the position of the point after rotation, apply the rotation formula. Rotation is a circular movement about the specific axis or point of rotation. In general, there are two common directions for rotation: clockwise and anti-clockwise or counter-clockwise.

Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.

Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

The sum of the denominators of the two fractions is -28.

The sum of the denominators of the two fractions can be found by first finding the equivalent fractions for 2/3 and 5/11 that fit the given conditions, and then adding the denominators together.

To find the equivalent fraction for 2/3 with a sum of 45 for the numerator and denominator, we can use the equation:

x + y = 45, where x is the numerator and y is the denominator.

Since the fraction is equivalent to 2/3, we can also use the equation 2/3 = x/y.

Solving for x in the first equation gives us x = 45 - y, and substituting this into the second equation gives us 2/3 = (45 - y)/y.

Multiplying both sides by 3y gives us 2y = 135 - 3y, and solving for y gives us y = 27.

This means that the denominator of the equivalent fraction for 2/3 is 27.

To find the equivalent fraction for 5/11 with a difference of 30 between the numerator and denominator, we can use the equation:

x - y = 30, where x is the numerator and y is the denominator.

Since the fraction is equivalent to 5/11, we can also use the equation 5/11 = x/y.

Solving for x in the first equation gives us x = 30 + y, and substituting this into the second equation gives us 5/11 = (30 + y)/y.

Multiplying both sides by 11y gives us 5y = 330 + 11y, and solving for y gives us y = -55.

This means that the denominator of the equivalent fraction for 5/11 is -55.

Therefore, the sum of the denominators of the two fractions is 27 + (-55) = -28.

The least accurate measurement among the options provided is 18050 m.Therefore, among the given options, 18050 m is the least accurate measurement due to its higher number of significant figures.

To determine the least accurate measurement, we need to consider the number of significant figures in each measurement. The measurement with the fewest significant figures indicates lower accuracy.

Among the options given:

a. 208 m has three significant figures.

b. 18050 m has five significant figures.

c. 0.08 m has two significant figures.

d. 0.750 m has three significant figures.

e. 12.0 m has three significant figures.

The measurement with the least accurate value is 18050 m because it has the highest number of significant figures among the options. A higher number of significant figures suggests a greater level of precision and accuracy in the measurement.

Significant figures represent the digits in a number that contribute to its precision. They include all the non-zero digits and any zeros that appear between non-zero digits or after a decimal point. In this case, the measurement 18050 m has five significant figures, indicating a high level of precision and accuracy.

On the other hand, measurements with fewer significant figures imply less precision and accuracy. For example, the measurement 0.08 m has only two significant figures, suggesting less certainty in the measurement compared to 18050 m.

The probability of a randomly selected dog being deaf is 0.194.

Given that 8% of dogs in a certain breed are white and if a dog is white, the probability it will be deaf is 70% while if it is not completely white, the probability of deafness is 15%.

Let A = The probability that a randomly selected dog is white.

A = 8% = 0.08.

Let B = The probability that a randomly selected white dog is deaf.

B = 70% = 0.70.

Let C = The probability that a randomly selected non-white dog is deaf.

C = 15% = 0.15.

Now, the probability of a randomly selected dog being deaf can be calculated as follows;`

P(dog is deaf) = P(white dog is deaf) + P(non-white dog is deaf)`

We know that `P(white dog) = 0.08` and `P(non-white dog) = 1 - P(white dog) = 1 - 0.08 = 0.92`

Therefore, the probability of a randomly selected dog being deaf is:

P(dog is deaf) = P(white dog is deaf) + P(non-white dog is deaf)`

P(dog is deaf) = (P(white dog) × P(white dog is deaf)) + (P(non-white dog) × P(non-white dog is deaf))`

Substituting the respective probabilities in the above equation, we get:

P(dog is deaf) = (0.08 × 0.70) + (0.92 × 0.15)P(dog is deaf) = 0.056 + 0.138 = 0.194
