The minimum probability that the number of defective parts on a particular shift will be between 46 and 74 is equals to the 0.9184.

Chebyshev's inequality is a theory that is used to describe the maximum number of extreme values in a probability distribution. We have, The expected number of defective parts produced in assembly line per shift = 60

So, sample size = 60

Standard deviations = 4

Standardized score for 46 = (46 - 60)/4

= -3.5

Standardized score for 74 = (74 - 60)/4

= 3.5

Hence by Chebyshev's inequality,

Minimum probability that the number of defective parts on a particular shift will be between 46 and 74 = (1 - 1/3.52)

= 0.9184

Hence required probability is 0.9184.

Answer:

The variable expression equation of the situation is;

x + 5 + x + 3·x - 7 = $73

The amount of money Jadah collects = $15

The amount of money Martez collects = $20

The amount of money Roana collects = $38

Step-by-step explanation:

The given parameters are;

The total amount of money they collect together = $73

The amount of money Martez collects = 5 + The amount of money Jadah collects

The amount of money Roana collects = 3 × The amount of money Jadah collects - 7

Let x represent the amount of money Jadah collects

Therefore, we have;

The amount of money Martez collects = 5 + x

The amount of money Roana collects = 3 × x - 7

The variable expression equation of the situation is given as follows;

The total amount of money the three collected = x + 5 + x + 3 × x - 7 = $73

∴ 5 × x - 2 = $73

5 × x - 2 = 73

5 × x  = 73 + 2 = 75

x = 75/5 = 15

x = 15

The amount of money Jadah collects = x = $15

The amount of money Martez collects = 5 + x = 5 + 15 = 20

The amount of money Martez collects = $20

The amount of money Roana collects = 3 × x - 7 = 3 × 15 - 7 = 38

The amount of money Roana collects = $38

In conclusion:

The penguin swims half the circumference of the circular island, which is equivalent to half the distance around the circle.

The circumference of a circle can be calculated using the formula:

C = πd,

where C is the circumference and d is the diameter of the circle.

Given that the diameter of the island is 20 meters, the radius (r) of the island is half the diameter, which is 10 meters.

Substituting the value of the radius into the formula, we have:

C = π * 10 meters = 10π meters.

To find half the circumference, we divide the total circumference by 2:

Half circumference = (10π meters) / 2 = 5π meters.

Therefore, the penguin swims a distance of 5π meters.

To construct a 98% confidence interval for B₁, we can use the t-distribution since the sample size is small (n = 12).

Given the sample mean (B₁ = 46), sample standard deviation (s = 5.7), and sum of squares (SSzz = 57), we can calculate the confidence interval.

The formula for a confidence interval is:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

For a 98% confidence level and n = 12, the critical value is approximately 2.681 (obtained from a t-distribution table).

The standard error is calculated as the sample standard deviation divided by the square root of the sample size (s / √n).

Plugging in the values:

Standard Error = 5.7 / √12 ≈ 1.647

Confidence Interval = 46 ± (2.681 * 1.647)

Therefore, the 98% confidence interval for B₁ is approximately (42.21, 49.79).

In conclusion, we can be 98% confident that the true value of B₁ falls within the range of 42.21 to 49.79 based on the given sample data.

Answer:

240000

Step-by-step explanation:

Answer:

240,000

Step-by-step explanation:

Pretend it is only 4 ten thousands. It would be 40,000. Since it is 24, there are 2.4 times more digits, so it would be 240,000 since it is at least 10 times more than a thousand which would be the 40,000 .

In case anyone needs 24 ten thousandths in the future:

0.0024

0.00024 is equal to 24 hundred-thousandths and there are tenths (0.1), hundredths (0.01), and thousandths (0.001). Then ten thousandths would just be a step lower (0.0001) but since there are 24, it would go into the thousandths place but have the four in the ten thousandths. So it would be 0.0024.

The values of a and b given vectors are a = 4 and b = 8.

for a set of vectors to be orthogonal, the dot product of any two distinct vectors in the set should be zero.

Let's check if this condition is satisfied for the given vectors:

u_1 • u_2 = (2)(4) + (1)(-5) + (-1)(3) = 8 - 5 - 3 = 0

u_1 • u_3 = (2)(2) + (1)(a) + (-1)(b) = 4 + a - b

u_2 • u_3 = (4)(2) + (-5)(a) + (3)(b) = 8 - 5a + 3b

We need to find values of a and b such that u_1, u_2, and u_3 form an orthogonal set. So we need u_1 • u_3 = 0 and u_2 • u_3 = 0.

u_1 • u_3 = 4 + a - b = 0, so a - b = -4 ...(1)

u_2 • u_3 = 8 - 5a + 3b = 0, so 5a - 3b = 8 ...(2)

We now have two equations in two variables (a and b). Solving these equations simultaneously, we get:

a = 4, b = 8

Substituting these values back into the dot products, we can check that u_1, u_2, and u_3 form an orthogonal set:

u_1 • u_2 = 0

u_1 • u_3 = 4 + 4 - 8 = 0

u_2 • u_3 = 8 - 20 + 24 = 0

Therefore, the values of a and b that make u_1, u_2, and u_3 an orthogonal set are a = 4 and b = 8.

(a) The horizontal asymptote is y = 2.

The vertical asymptote is x = 1.

The y-intercept is (0, -1).

The x-intercept is (1, 0).

To find the horizontal asymptote, we compare the degrees of the numerator and denominator. In this case, both have a degree of 1. Therefore, the horizontal asymptote is given by the ratio of the leading coefficients, which is y = 2.

To find the vertical asymptote, we set the denominator equal to zero and solve for x:

x - 1 = 0

x = 1

Thus, the vertical asymptote is x = 1.

To find the y-intercept, we substitute x = 0 into the function:

f(0) = (2(0) - 1) / (0 - 1) = -1

Therefore, the y-intercept is (0, -1).

To find the x-intercept, we set the numerator equal to zero and solve for x:

2x - 1 = 0

2x = 1

x = 1/2

Thus, the x-intercept is (1/2, 0).

The graph illustrates a slant asymptote of y = 2, a vertical asymptote at x = 1, a y-intercept at (0, -1), and an x-intercept at (1/2, 0).

The rational function f(x) = (2x - 1) / (x - 1) has a horizontal asymptote at y = 2, a vertical asymptote at x = 1, a y-intercept at (0, -1), and an x-intercept at (1/2, 0).

(b) Direct Answer:

The horizontal asymptote is y = 1.

The vertical asymptotes are x = 2 and x = -2.

The y-intercept is (0, -3/4).

The x-intercepts are (-4, 0) and (3, 0).

To find the horizontal asymptote, we compare the degrees of the numerator and denominator. In this case, both have a degree of 2. Therefore, the horizontal asymptote is given by the ratio of the leading coefficients, which is y = 1.

To find the vertical asymptotes, we set the denominator equal to zero and solve for x:

x^2 - 4 = 0

(x + 2)(x - 2) = 0

x = -2 or x = 2

Thus, the vertical asymptotes are x = -2 and x = 2.

To find the y-intercept, we substitute x = 0 into the function:

f(0) = (0^2 + 0 - 12) / (0^2 - 4) = -3/4

Therefore, the y-intercept is (0, -3/4).

To find the x-intercepts, we set the numerator equal to zero and solve for x:

x^2 + x - 12 = 0

(x - 3)(x + 4) = 0

x = 3 or x = -4

Thus, the x-intercepts are (-4, 0) and (3, 0).

The graph illustrates a horizontal asymptote at y = 1, vertical asymptotes at x = -2 and x = 2, a y-intercept at (0, -3/4), and x-intercepts at (-4, 0) and (3, 0).

The rational function f(x) = (x^2 + x - 12) / (x^2 - 4) has a horizontal asymptote at y = 1, vertical asymptotes at x = -2 and x = 2, a y-intercept at (0, -3/4), and x-intercepts at (-4, 0) and (3, 0).

The image of (-5,-9) after dilation by a scale factor of 3 centered at the origin is (-15,-27).

To find the image of the point (-5,-9) after dilation by a scale factor of 3 centered at the origin.

We can use the following formula:

(x', y') = (kx, ky)

Where (x', y') are the coordinates of the dilated point, (x, y) are the coordinates of the original point, and k is the scale factor.

In this case, k = 3, and the coordinates of the original point are (-5,-9).

So we have:

x' = 3(-5) = -15

y' = 3(-9) = -27

Therefore, the image after dilation is (-15,-27).

A' = 3/2 * (0,-3) = (0,-9/2) = (0,-4.5) (0,-4.5)

C' = 3/2 * (0,5) = (0, 15/2) = (0,7.5) (0,7.5)

B' = 3/2 * (6,6/3) = (9 , 9/2) = (9,4.5) (9,4.5)

The two lengths which separate the top 9% and bottom 9% of nails are equal to 5.52 cm and 5.44 cm respectively and any nail length which are outside the calculated range can be rejected.

Mean = 5.48 cm

Standard deviation = 0.03cm

Use the z-score formula to find the corresponding z-scores for the top 9% and bottom 9% of the normal distribution,

For the top 9%, we have,

Attached table,

z = InvNorm(1 - 0.09)

 ≈ 1.34

For the bottom 9%, we have,

z = InvNorm(0.09)

  ≈ -1.34

where InvNorm is the inverse normal cumulative distribution function.

Using the z-score formula, we have,

z = (x - μ) / σ

Rearranging the formula, we can solve for x,

x = μ + zσ

Length that separates the top and bottom 9% of nails is,

For the top 9%, we have,

x = 5.48 + 1.34(0.03)

  ≈ 5.52

For the bottom 9%, we have,

x = 5.48 - 1.34(0.03)

   ≈ 5.44

Therefore, the two lengths that separate the top 9% and bottom 9% of nails are 5.52 cm and 5.44 cm, respectively. Any nail length outside this range can be rejected.

In this proof, we first assume that A ⊆ B and take an arbitrary element x of B^c. Then, we assume for the sake of contradiction that x is also an element of A.

Using the fact that A ⊆ B, we show that x must also be an element of B, which contradicts our assumption that x is in B^c. This contradiction allows us to conclude that our assumption that x is in A must be false, and therefore x is in A^c. Since x was arbitrary, we have shown that for any element of B^c, it must also be in A^c. Therefore, B^c ⊆ A^c.

To prove the statement "If A ⊆ B, then B^c ⊆ A^c," we can use the following proof skeleton:

Proof:
1. Let x be an arbitrary element of B^c.
2. Assume for the sake of contradiction that x is an element of A.
3. Since A ⊆ B, we know that x is also an element of B.
4. But this contradicts our assumption that x is an element of B^c.
5. Therefore, our assumption that x is an element of A must be false.
6. Thus, x is an element of A^c.
7. Since x was arbitrary, we have shown that for any x in B^c, x is in A^c.
8. Therefore, B^c ⊆ A^c, as required.
