PLEASE HELP
5.Two mechanics were working on your car. One can complete the given job
in six hours, but the new guy takes eight hours. They worked together for
the first two hours, but then the first guy left to help another mechanic on
a different job. How long will it take the new guy to finish your car?

The metric unit from pounds to tons is 250 pounds = 0.125 tons

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

250 pounds = how many tons

As a general rule, we have

1 pound = 0.0005 tons

Multiply both sides of the equation by 250

So, we have

250 * 1 pound = 0.0005 tons * 250

Evaluate the products

250 pounds = 0.125 tons

Hence, the conversion is 250 pounds = 0.125 tons

The nonlinear relation can be transformed into a linear regression model by identifying the predictor variables and response variable, determining the coefficients, and writing the model in the form y = b0 + b1x1 + b2x2 + b3x3 + ... + bnxn.

Based on the information in the table, the nonlinear relation can be transformed into the following linear regression model: y = b0 + b1x1 + b2x2 + b3x3 + ... + bnxn.

This type of regression model is known as a multiple linear regression, as it includes multiple predictor variables (x1, x2, x3, ... xn) and a single response variable (y). The goal of this type of model is to find the best-fitting line that describes the relationship between the predictor variables and the response variable.

In order to transform the nonlinear relation into a linear regression model, we need to first identify the predictor variables and the response variable. Next, we need to determine the coefficients (b0, b1, b2, b3, ... bn) that best fit the data. This is typically done using a method called least squares, which minimizes the sum of the squared differences between the observed values and the values predicted by the model.

Once we have determined the coefficients, we can write the linear regression model as: y = b0 + b1x1 + b2x2 + b3x3 + ... + bnxn. This model can then be used to make predictions about the response variable based on the values of the predictor variables.

In conclusion, the nonlinear relation can be transformed into a linear regression model by identifying the predictor variables and response variable, determining the coefficients, and writing the model in the form y = b0 + b1x1 + b2x2 + b3x3 + ... + bnxn.

c = 25 * 5^t

Step-by-step explanation:

This equation best suits N on the scale as it follows the pattern of the number of colonies being 5 times the previous year.

(a) The greatest common divisor of \(x^3\) - 6x - 7 and \(x^4\) is 1.

(b) The greatest common divisor of \(x^2\)- 1 and 2\(x^7\) - 4x\(^5\) + 2 is 1.

(a) To find the greatest common divisor (GCD) of the polynomials, we can use polynomial long division.

Dividing \(x^3\) - 6x - 7 by \(x^4\), we get a remainder of \(x^3\) - 6x - 7.

Since the remainder is non-zero, the GCD of \(x^3\) - 6x - 7 and \(x^4\) is 1.

(b) To find the GCD of \(x^2\) - 1 and 2\(x^7\) - 4\(x^5\) + 2, we can again use polynomial long division.

Dividing 2\(x^7\) - 4\(x^5\) + 2 by \(x^2\) - 1, we get a remainder of 2\(x^5\) + 2.

Since the remainder is non-zero, the GCD of \(x^2\) - 1 and 2\(x^7\) - 4\(x^5\) + 2 is 1.

Step-by-step explanation:

We would like to find Vito's average reading rate in pages per hour.

First, define average rate. It's essentially speed and is calculated by dividing total "distance" by total time. Here, the "distance" is simply the total number of pages Vito reads, which is 96 pages. The time is 2 hours 40 minutes.

However, note that the answer has units where the time is solely in hours - no minutes. This means we must convert our time of 2 hours 40 minutes into hours.

2 hours is already in hours, so don't worry about that.

There are 60 minutes in an hour, so 40 minutes will be 40/60 = 2/3 of an hour. Thus, the total time Vito has spent reading 96 pages is 2 hours + 2/3 hours, or (2 + 2/3) = (6/3 + 2/3) = 8/3 hours.

Now, we can calculate his rate:

avg rate = total "distance" ÷ total time

avg rate = 96 pages ÷ 8/3 hours = 96 * (3/8) = 36

Vito's average rate is hence 36 pages per hour, or C.

~ an aesthetics lover

Vito's average rate of pages per hour is approximately 36. the answer is C. 36.

To find Vito's average rate of pages per hour, we need to convert the time from hours and minutes to hours.

2 hours and 40 minutes can be converted to 2 + (40/60) = 2.67 hours.

Now we can calculate the average rate of pages per hour by dividing the total number of pages read (96) by the time in hours (2.67):

Average rate = Total pages / Time in hours = 96 / 2.67 ≈ 35.92

Rounding to the nearest whole number, Vito's average rate of pages per hour is approximately 36.

Therefore, the answer is C. 36.

Answer:

\(\dfrac{1}{729}\)

Step-by-step explanation:

\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)

First, we should evaluate inside the large parentheses:

\((-3)^2 = (-3)\cdot (-3) = 9\)

We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,

\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)

       ↑1 ↑2 ↑3 times because the exponent is 3

Next, we can put the value 9 into where \((-3)^2\) was originally:

\((9)^{-3}\)

We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,

\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)

Finally, we can apply this principle to the \(9^{-3}\):

\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

The  function that represents how the amount of fuel changes as a function of distance flown is

\(f(x)=-0.9x+665\)

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

\(y=mx+b\)        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

\(f(x)=-0.9x+665\)        ...(ii)

On comparing (i) and (ii), we get

\(m=-0.9\)

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

According to the question we have  the 99% UCB on the mean time of the race is 223.

The formula for finding the upper confidence bound (UCB) is UCB = Mean + (Zα/2)(σ/√n), where Mean is the sample mean, Zα/2 is the z-score for the desired level of confidence, σ is the population standard deviation (which is not given, so we'll use the sample standard deviation instead), and n is the sample size.

We are given the sample of times as follows:137, 143, 153, 162, 168, 176, 190, 192, 196, 203, 218, 223, 236, 243, 252, 269, 271, 276, 283, 287.

We'll need to calculate the sample mean and standard deviation before we can find the UCB. Using a calculator, we get: mean ≈ 207.65s ≈ 48.41 Next, we'll use a table or calculator to find the z-score for a 99% confidence interval, which is Zα/2 = 2.576.

Now we can plug in the values we know to get the UCB:UCB = mean + (Zα/2)(σ/√n)UCB ≈ 207.65 + (2.576)(48.41/√20)UCB ≈ 223.02 .Therefore, the 99% UCB on the mean time of the race is 223.

A sample size of 76 would be required to estimate the population mean with a margin of error of 4 and a 98% level of confidence.

To determine the sample size required to estimate the population mean with a specific margin of error and level of confidence, we can use the formula:

n = (Z * σ / E)²

where

n = required sample size

Z = Z-score corresponding to the desired level of confidence

σ = standard deviation of the population

E = desired margin of error

here, we have that

the standard deviation (σ) is given as 15,

the margin of error (E) is 4 and

the level of confidence is 98% and For a 98% confidence level, the Z-score is approximately 2.33.

Plugging the values into the formula:

Therefore, the correct answer is: b) g'(x) = (3/2√(3x))

To find the derivative of g(x) = √(3x) - 1, we can apply the power rule and the chain rule.

The power rule states that the derivative of x^n is n*x^(n-1).

Let's denote f(x) = 3x and h(x) = √x.

The derivative of f(x) is f'(x) = 3, as it is a constant.

The derivative of h(x) is h'(x) = (1/2)√x * (1/x) = (1/2√x).

Now, applying the chain rule, we can find the derivative of g(x) as follows:

g'(x) = f'(x) * h'(f(x))

g'(x) = 3 * (1/2√(3x)) = (3/2√(3x)).

Therefore, the correct answer is:

b) g'(x) = (3/2√(3x))
