For the same sample size, a 90% confidence interval is narrower than a 95% confidence interval is not true. The correct answer is: for the same sample size, a 90% confidence interval is narrower than a 95% confidence interval.

A confidence interval is an estimated range of values that likely contains the true population parameter. A higher confidence level requires a wider interval because the goal is to be more confident that the true parameter falls within the interval. As the confidence level decreases, the interval narrows, meaning it is more precise, but there is less confidence in its accuracy. So, a 90% confidence interval will be narrower than a 95% confidence interval for the same sample size.

Answer: its number two

It's important to note that the resulting polynomial is not in P_3, as it has a degree of 4.

The student's question involves a linear operator L acting on a polynomial p(x) in P_3, the space of polynomials of degree 3 or less. The linear operator is defined as L(p(x)) = x * p'(x) * p''(x). Let's find the result of this operation step-by-step.

1. Determine the general form of a polynomial in P_3: A polynomial in P_3 has the form p(x) = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants.

2. Compute the first derivative p'(x): To find the first derivative, differentiate p(x) with respect to x. We get p'(x) = 3ax^2 + 2bx + c.

3. Compute the second derivative p''(x): Next, differentiate p'(x) with respect to x. We get p''(x) = 6ax + 2b.

4. Compute the product x * p'(x) * p''(x): Multiply the first derivative, second derivative, and x together. We have (x)(3ax^2 + 2bx + c)(6ax + 2b).

5. Simplify the expression: After multiplying and combining like terms, we get L(p(x)) = 18a^2x^4 + 12abx^3 + 4a^2x^3 + 4b^2x^2 + 12acx^2 + 6bcx + 2cx^2.

This is the resulting polynomial after applying the linear operator L to a polynomial p(x) in P_3. However, it's important to note that the resulting polynomial is not in P_3, as it has a degree of 4.

Let the unknown angle be x

\(\\ \sf\longmapsto x+98=180\)

\(\\ \sf\longmapsto x=180-98\)

\(\\ \sf\longmapsto x=82\)

Increasing order:-

\(\\ \sf\longmapsto 17<81<82\)

Shortest side has shortest opposite angle and largest side has largest opposite angle.

Increasing order

\(\\ \sf\longmapsto AC<AB<BC\)

Here in given ∆ABC we have been given that measure of angles C & B are 81° and 17° respectively. So first of all we need to find out the angle A. By sum of property of triangle we know that sum of all angles of triangle tends to 180°. Let 'x' be the angle for measure of angle A.

Now,

\(:\implies\tt{x + c + b = 180}\)

\(:\implies\tt{x + 81 + 17 = 180}\)

\(:\implies\tt{x + 98 = 180}\)

\(:\implies\tt{x = 180 - 98}\)

\(:\implies\tt{x = 85}\)

Now for the increasing order for the given angles can be given by,

Answer:

Step-by-step explanation:

Let's call the number of students who picked sport "s" and the number of students who picked painting "p". We know:

p + s = 5 (the number of students who picked painting and sport)

42 - p - s = 8 (the number of students who did not pick either)

s = 2p (twice as many picked sport as painting)

From the first equation, we can solve for p:

\(\sf:\implies{p + 2p = 5}\)

\(\sf:\implies{3p = 5}\)

\(\sf:\implies{p = 5/3}\)

So, 5 students picked painting and 10 students picked sport. And the number of students who picked sport but not painting is:

s - p = 10 - 5/3 = 10 - 5/3 = 25/3.

Based on the given data,the calculated Economic Order Quantity( EOQ) is approximately 360.50 units.

Based on the given data, we can calculate the Economic Order Quantity (EOQ) using the formula:

EOQ = sqrt((2 * demand * setup cost) / holding cost)

First, we need to determine the setup cost, which is given as $120 per order. The holding cost is $35 per unit.

Demand = 19012 units per quarter

Setup cost = $120 per order

Holding cost = $35 per unit

Substituting these values into the EOQ formula:

EOQ = sqrt((2 * 19012 * 120) / 35)

= sqrt(4562880 / 35)

≈ sqrt(130082.29)

≈ 360.50

Therefore, the calculated EOQ is approximately 360.50 units.

To check the EOQ figures, you would compare this result to their current order quantity. If their current order quantity is close to 360.50 units, then the EOQ figures are in line with their current practice. However, if the current order quantity significantly differs from 360.50 units, further analysis may be required to understand the factors influencing their ordering decisions.

Given that a is in Quadrant 2 and sin(a) =, we need to calculate the value of a. However, the value of sin(a) is missing in the question.

Please provide the value of sin(a) to proceed further. Similarly, given that B is in Quadrant 1 and tan(B) = 1, we need to calculate the exact answers for sin(2/3), cos(26), and tan(23).Here are the steps to calculate the exact answers for sin(2/3), cos(26), and tan(23):Given that B is in Quadrant 1 and tan(B) = 1:Since

tan(B) = opposite / adjacent We can assume opposite side as x and adjacent side as 1. Therefore, we get:

Tan(B) = opposite / adjacent

=> 1 = x/1

=> x = 1 Hence, the opposite side in the right triangle is 1.

Now, we can use the Pythagorean Theorem to find the adjacent side. Using the Pythagorean Theorem, we get:

hypotenuse^2 = opposite^2 + adjacent^2

=> hypotenuse^2 = 1 + 1

=> hypotenuse = √2a.

sin(2a) = sin 16/9 Given that a is in Quadrant 2, the value of cos(a) is positive and sin(a) is negative.

sin(a) = -16/9

cos(a) = sqrt(1 - sin^2(a)

= sqrt(1 - (256/81))

= sqrt(25/81)

= 5/9cos(2a)

= cos^2(a) - sin^2(a)

= (5/9)^2 - (16/9)^2

= 25/81 - 256/81= -231/81

tan(2a) = (2tan(a))/(1 - tan^2(a)

)= 2 * (-16/9) / (1 - (-16/9)^2)

= -32/145 Given that B is in Quadrant 1 and

tan(B) = 1:b. cos(26)We know that

cos(90 - 26) = sin(26) and

sin(90 - 26) = cos(26)

cos(90 - 26) = sin(26)

= sin(64)= cos(26)c. tan(23) We can use the identity

tan(2x) = 2tan(x) / (1 - tan^2(x))

tan(2*23) = tan(46)

= 2tan(23) / (1 - tan^2(23))

=> 1/tan(46) = 2/tan(23) - tan(23)

=> tan(23)

= (2 / tan(46)) + tan(46) We know that

tan(90 - 46)

= cot(46)

= cot(44)

= 1/tan(44) Substituting this value, we get

tan(23) = (2 / (1/tan(44))) + (1/tan(44))

= 2tan(44) + tan(44)

Answer:

Step-by-step explanation:

A sample size of 1500 or 10000 is generally sufficient for a reasonably accurate poll if proper methodology and random sampling techniques are utilized.

The correct answer is option A and B.

Determining a sufficient sample size for a reasonably accurate poll requires considering several factors: the population size, desired margin of error, confidence level, and expected variability within the population.

To calculate the sample size, we can use the formula:

n = (\(Z^2 * p * (1-p)) / (E^2)\)

Where:

n = required sample size

Z = Z-score corresponding to the desired confidence level

p = estimated proportion or expected prevalence in the population

E = desired margin of error

For example, let's assume we want a 95% confidence level, a margin of error of 5%, and an estimated prevalence of 50% (which provides the maximum required sample size). Plugging these values into the formula, we have:

Z = 1.96 (corresponding to a 95% confidence level)

E = 0.05 (5% margin of error)

p = 0.5 (estimated prevalence)

n = (\(1.96^2\) * 0.5 * (1-0.5)) / (0.05^2)

n = (3.8416 * 0.25) / 0.0025

n = 0.9604 / 0.0025

n = 384.16

Therefore, the required sample size would be approximately 384. This calculation assumes a worst-case scenario (p = 0.5) to ensure a conservative sample size estimate.

Based on the given options:

- A sample size of 1500 exceeds the required sample size, providing a reasonably accurate poll.

- A sample size of 10000 is more than sufficient and would yield an even more accurate poll.

- Sampling 10 percent of the population can be considered sufficient, depending on the total population size.

- Sampling 100 percent of the population would provide the most accurate results, but it is usually impractical or impossible.

In conclusion, both a sample size of 1500 and 10000 are correct answer making option A and B the correct answer.

A random sample is then drawn from each stratum using the stratified sampling approach, which divides the population into subgroups (strata) depending on certain criteria (stratum).

The university's student body serves as the population in this situation, while the eight schools serve as the subgroups (business, liberal arts, engineering, etc.).

The administrator can reach conclusions regarding the cost of textbooks for each institution by selecting a sample of 50 students from each college to make sure the sample is representative of the varied student body.

This approach is helpful when a population is divided into multiple subgroups and the researcher wants to make sure that the sample fairly reflects each segment.

Step-by-step explanation:

hopefully I'm correct

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.
