The value of derivative f '(x) can be simplified to f '(x) = -20x³+4x²+8x+1.Yes the answer agrees.

To find the derivative of f(x) = (1 + 4x²)(x - x²) using the product rule, we first take the derivative of the first term, which is 8x(x-x²), and then add it to the derivative of the second term, which is (1+4x²)(1-2x). Simplifying this expression, we get f '(x) = 8x-12x³+1-2x+4x²-8x³.  

To find the derivative by multiplying first, we would have to distribute the terms and then take the derivative of each term separately, which would be a more tedious process and would not necessarily give us the same answer as using the product rule. .

Dollars= $45.46

Step-by-step explanation:

Giving the following information:

Pesos= 1,047.5

Exchange rate:

5 dollars= 115.21

First, we need to determine the exchange rate for 1 dollar:

1 dollar= 115.21/5

1 dollar= 23.042 pesos

Now, for 1,047.5 pesos:

Dollars= total pesos / exchange rate

Dollars= 1,047.5/23.042

Dollars= $45.46

Answer:

45.46 dollars

Step-by-step explanation:

The rate was the temperature increased by 1 degree for every 1 hour that passed.

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

Kaylee carried out a scientific experiment. For a period of time, the temperature of a compound grew by one degree per hour.

The rate at which the temperature of the compound rose is 1 degree per hour. This means that for every hour that passed, the temperature of the compound increased by 1 degree.

The units for the rate are degrees per hour, which means that the temperature increased by 1 degree for every 1 hour that passed.

The probability that a randomly chosen test-taker will score between 470 and 530 is 0.2358 (or 23.58% when expressed as a percentage).

To solve this problem, we need to use the standard normal distribution formula:
Z = (X - μ) / σ
where Z is the standard score (z-score) of a given value X, μ is the mean, and σ is the standard deviation.
First, we need to convert the given values of 470 and 530 to z-scores:
Z1 = (470 - 500) / 100 = -0.3
Z2 = (530 - 500) / 100 = 0.3
Next, we need to find the probability that a randomly chosen test-taker will score between these two z-scores.

We can use a standard normal distribution table or a calculator to find the area under the curve between -0.3 and 0.3.
Using a calculator or an online tool, we find that the area under the curve between -0.3 and 0.3 is approximately 0.2358.

For x = 4, the residual value is -7.586. Therefore, the correct option is b.

We are required to find the residual value for x = 4 using the given data and the LSRL ý = 20.47 + 3.486x.

To find the residual value, follow these steps:

1. Find the predicted value for x = 4 using the LSRL equation.

  ý = 20.47 + 3.486(4) = 20.47 + 13.944 = 34.414

2. Locate the actual value of y when x = 4 in the data.

  x: 1  2  3  4  5  6

  y: 43 37 29 22 22 11

  For x = 4, the actual y value is 22.

3. Calculate the residual value using the formula:

  Residual = Actual value - Predicted value

  Residual = 22 - 34.414 = -7.586

Hence, the residual value for x = 4 is -7.586, which corresponds to option b: -7.586.

Note: The question is incomplete. The complete question probably is: Suppose you have the following data: x 1 2 3 4 5 6 y 43 37 29 22 22 11 and the lsrl is ý = 20.47 + 3.486. Find the residual value for x = 4. a) 34.414 b) -7.586 c) 42 d) 7.586 e) None of the above.

Answer:

y=-5x-3

Step-by-step explanation:

put -1 and 1 in equation and you will get the answer

The equation that best represents a line perpendicular will be y = - 5x - 3. Then the correct option is A.

Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0

The equation of the line passing through (-1, 2) and (1, -8). Then the equation of the line will be

y + 8 = [(-8 - 2) / (1 + 1)] (x - 1)

y + 8 = -5x + 5

y = - 5x - 3

The equation that best represents a line perpendicular will be y = - 5x - 3. Then the correct option is A.

The probability that Jake will earn at least 30 points on a throw is 0.335

The attached image represents the missing part of the question.

From the attached image, we can see that:

For Jake to earn at least point, he must hit the three circles (starting from the inner circle)

The radius of the yellow circle is:

Radius = 3

While the width of the other circles is:

Width = 4

The total area of the sections that give a point of at least 30 is:

A₁ = π * (3 + 4 + 4)² = 121π

The total area of all the sections is:

A₂ = π * (3 + 4 + 4 + 4 + 4)² = 361π

The probability of getting at least 30 points is:

P(At least 30) = 121π/361π

Evaluate

P(At least 30) = 0.335

Hence, the probability that Jake will earn at least 30 points on a throw is 0.335

The expression used by commutative property of addition and the associative property of multiplication to rewrite the expression (3x2) x 5+7 is 7+3.(2.5).

The commutative property or commutative law of mathematics states that while executing mathematical operations, the order of terms is irrelevant.

Only addition and multiplication operations are under the purview of the commutative property. As a result, it means that while adding or multiplying any two integers, we can swap the positions of the numbers. One of the main characteristics of integers is this.

According to the commutative property of multiplication, even if the positions of the two integers are switched around, the result of multiplying two integers will still be the same.

Which of the following is an accurate definition for the power of a statistical test is C. The power of a statistical test refers to the probability of rejecting a false null hypothesis. This means that the test is able to correctly identify when there is a significant difference between two groups or conditions.

statistical tests are used to determine whether the results of an experiment are likely due to chance or whether there is a real effect. The null hypothesis states that there is no significant difference, while the alternative hypothesis states that there is. The power of a statistical test refers to the ability of the test to correctly reject the null hypothesis when it is false, and thus support the alternative hypothesis.

The null hypothesis to test the faculty member's claim that the improvement is no more than 3% at the 5% significance level is that the true mean score improvement on the outcomes assessment test is equal to or less than 3%.

The null hypothesis is a statement that assumes there is no significant difference or relationship between two variables in a population, or that any observed difference or relationship is due to chance or sampling error. It is usually denoted by "H0" and is used in statistical hypothesis testing to determine whether there is evidence to support an alternative hypothesis.

In the given question,

The null hypothesis to test the faculty member's claim that the improvement is no more than 3% at the 5% significance level would be:

H0: The true mean score improvement on the outcomes assessment test is equal to or less than 3%.

This hypothesis assumes that there is no significant improvement in the mean score on the outcomes assessment test as a result of the review course. The alternative hypothesis would be:

Ha: The true mean score improvement on the outcomes assessment test is greater than 3%.

This hypothesis assumes that there is a significant improvement in the mean score on the outcomes assessment test as a result of the review course.

To test these hypotheses, we would use a one-tailed t-test with a significance level of 0.05 and calculate the t-value and p-value based on the sample data. If the p-value is less than 0.05, we would reject the null hypothesis and conclude that there is evidence of a significant improvement in the mean score on the outcomes assessment test as a result of the review course. If the p-value is greater than or equal to 0.05, we would fail to reject the null hypothesis and conclude that there is no evidence of a significant improvement in the mean score on the outcomes assessment test as a result of the review course.

The temperature at 6pm was of  -5.1ºF.

This problem can be solved by using system of equations.

A system of equations means when there are  two or more variables that are related, and equations are made to find the values of each variable of the problem.

It is given that at 9 am, the temperature was -12.3°F. Between 9am and the noon, the temperature rose 12°F. So, the temperature at noon was of -12.3 + 12 = -0.3ºF.

Also, between the noon and  3pm, the temperature went up 11.5°F. So, at 3 pm, the temperature was of -0.3 + 11.5 = 11.2 ºF.

Further, between 3pm and 6pm, the temperature dropped 16.3°F.So, the temperature at 6 pm was of 11.2 - 16.3 = -5.1 ºF.
