Option D is the correct answer.

We have,

Edouard Manet's painting "Luncheon on the Grass" was first rejected by the Paris Salon in 1863, as it was considered scandalous due to the nudity of the female figure in the painting.

In response to this rejection,

Emperor Napoleon III ordered an exhibition to be held for all the rejected paintings, which was known as the Salon des Refusés (Salon of the Refused).

95% confidence that machine calibrated properly is (48.536, 51.424).

We have given that,

n = 25

mean of x = 49.98 mm

S = 0.14 mm

μ = 50.00 mm

and CI = 95%

from t-table we know that,

t at 95% and n - 1 = 25 - 1 = 24 is 2.064

Therefore 95% of CI means that

(x - 2.064 × S√n, x + 2.064 × S√n)

(49.98 - 2.064 × 0.14√25, 49.98 + 2.064 × 0.14√25)

Answer:

it's not fair

Step-by-step explanation:

... if Rebecca rolled the dice it's most likely going to give a 6 or a higher number if Blake rolled the same too would have happened thus it would be fair if the dice was 3 sided

Rebecca and Blake decide to roll a pair of fair 6-sided dice to determine who has to clean their dishes. If the sum is 5 or 6, then Rebecca will clean the dishes. If the sum is 8 or 9, then Blake will clean the dishes. If the sum is anything else, they'll roll again. This is a fair method of decision making by law of probability because both Rebecca and Blake are equally likely to wash the dishes.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Total number of observations in sample space when a pair of dice is rolled = 6² = 36

Number of observations where sum is 5 or 6 = 9

((1,4)(4,1)(2,3)(3,2)(1,5)(5,1)(4,2)(2,4)(3,3))

Probability that Rebecca will clean the dishes = 9/36 = 0.25

Number of observations where sum is 8 or 9 = 9

((2,6)(6,2)(3,5)(5,3)(4,4)(3,6)(6,3)(4,5)(5,4))

Probability that Blake will clean the dishes = 9/36 = 0.25

Since, the probabilities of Rebecca and Blake cleaning the dishes are equal, the method of decision making is fair.

After 62.63 years Mr. Reihman's account outgrown Mr. Van Ausdall,

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.

Given, Van Ausdall and Reihman both make the decision to start retirement funds.

Mr. Reihman contributes $10,000 at a constant rate of 7%, and

Mr. Van Ausdall contributes $35,000 at a continual rate of 5%.

Let "x" be the time when Mr. Reihman and Mr. Van Ausdall will have the same amount of money

From the general formula of continuous growth of the amount:

Amount = Principal amount*e^(rt)

Where r =rate of interest

t = time

At time x Mr. Reihman will have = 10,000*e^(7%*x)

At time x Mr. van will have =35,000* e^(5%*x)

Since at x, they both will have the same amount

thus,

10,000*e^(7%*x)  =3 5,000* e^(5%*x)

e^(7x/100 -5x/100) = 3.5

Taking natural logs on both the side

2x/100 = ln3.5

\(\frac{3}{2}/\frac{2}{3}\\\\=\frac{3}{2}*\frac{3}{2}\\\\=1\)

The dimension of V when the derivative is 0 is 1 since the l polynomial reduces to a 1-dimensional space.

The dimension of a linear space in which all polynomials with degrees less than 2 is 0 is 1. To estimate the dimension, we must take into account the basic elements of the space.

Let V be the collection of polynomials with a degree less than 2. Then the basic elements of V are 1, x

Let f(x)be a polynomial in V. Then f(x) can be written as f(x)= a0 + a1 x for some constants  

We know that the derivative of f(x) is f'(x) =\(a_1$$\)

Therefore, when the derivative f'(x) is 0, it means that a1 = 0. In this case, the polynomial f(x) reduces to f(x) = a0, which is a constant.

So, the dimension of V when the derivative is 0 is 1, since the l polynomial reduces to a 1-dimensional space.

Answer:

the answer is E

Step-by-step explanation:

Answer:

a) \( E = \frac{49.2-17.6}{2}= 15.8\)

b) For this case we have 95% of confidence that the true mean would be between \(\pm 15.8\) units respect the true mean.

c) \(n=(\frac{2.58(45)}{11})^2 =111.39 \approx 112\)

So the answer for this case would be n=112

d) \(36.5-2.58\frac{45}{\sqrt{112}}=25.53\)    

\(36.5+2.58\frac{45}{\sqrt{112}}=47.47\)

Step-by-step explanation:

Part a

For this case we know that the cinfidence interval for the true mean is given by:

\( \bar X \pm E\)

Where E represent the margin of error. For this case we have the confidence interval at 95% of confidence and we can estimate the margin of error like this:

\( E = \frac{49.2-17.6}{2}= 15.8\)

Part b

For this case we have 95% of confidence that the true mean would be between \(\pm 15.8\) units respect the true mean.

Part c

The margin of error is given by this formula:

\( ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}\)    (a)

And on this case we have that ME =11 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

\(n=(\frac{z_{\alpha/2} \sigma}{ME})^2\)   (b)

The critical value for 99% of confidence interval now can be founded using the normal distribution. The critical value would be \(z_{\alpha/2}=2.58\), replacing into formula (b) we got:

\(n=(\frac{2.58(45)}{11})^2 =111.39 \approx 112\)

So the answer for this case would be n=112

Part d

The confidence interval for the mean is given by the following formula:

\(\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}\)   (1)

Replcaing the info given we got:

\(36.5-2.58\frac{45}{\sqrt{112}}=25.53\)    

\(36.5+2.58\frac{45}{\sqrt{112}}=47.47\)

This means we have to multiply each of the coordinate values by 4

We have that as:

Answer:

For the first one x= 60 degrees

Second one x= 125 degrees

Step-by-step explanation:

a) To figure out this we can see that the total of angles in a 5- angled shape is 540 degrees.

So (2x X 4) + x = 540 degrees

= 9x= 540

= x = 60

b) To figure out this we can see that the total of angles in a 7- angled shape is 900 degrees.

So 60+2x+x+x+x+x+90= 900

= 150 +6x= 900

= 6x= 750

= x= 125

Step-by-step explanation:

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Answer:

the probability that a randomly selected student received an A, B, or C is approximately 0.769, or about 76.9%.

Step-by-step explanation:

To find the probability that a randomly selected student received an A, B, or C, we need to add up the number of students who received each of these grades and divide by the total number of students in the class.

The total number of students in the class is:

total = A + B + C + D + E = 40 + 40 + 33 + 20 + 14 = 147

The number of students who received an A, B, or C is:

A + B + C = 40 + 40 + 33 = 113

Therefore, the probability that a randomly selected student received an A, B, or C is:

P(A or B or C) = (A + B + C) / total = 113 / 147 ≈ 0.769

So the probability that a randomly selected student received an A, B, or C is approximately 0.769, or about 76.9%.
