c) It would be larger, because higher confidence requires a larger margin of error.

When increasing the confidence level from 95% to 99%, the margin of error of the confidence interval tends to increase. This is because a higher confidence level means we want to be more certain or have a higher level of confidence in capturing the true population parameter.

To achieve a higher confidence level, we need to widen the interval to account for more potential variability in the population. As a result, the margin of error increases, reflecting the increased uncertainty and the need for a larger range of values to capture the true population parameter with higher confidence.

Therefore, the margin of error of a 99% confidence interval, based on the same sample, would be larger compared to the 95% interval.

Answer: \(4.\ \ \ \dfrac{4\sqrt{mn}}{m^2}\) .

Step-by-step explanation:

The given expression: \(\sqrt{\dfrac{16n}{m^3}}\)

'

since \(16=4^2\)

\(m^3=m^{2+1}= m^2\times m\)   [\(a^{n+m}=a^n\times a^m\)]

Now, the given expression becomes,

\(\sqrt{\dfrac{4^2n}{m^2\timesn}}=\dfrac{4\sqrt{n}}{m\sqrt{m}}\)

Since there is root in denominator , so we need to rationalize

\(\dfrac{4\sqrt{n}}{m\sqrt{m}}\times\dfrac{\sqrt{m}}{\sqrt{m}}=\dfrac{4\sqrt{mn}}{m\times\sqrt{m}\times\sqrt{m} }\\\\=\dfrac{4\sqrt{mn}}{m\times m}\\\\=\dfrac{4\sqrt{mn}}{m^2}\)

Hence, the correct option is \(4.\ \ \ \dfrac{4\sqrt{mn}}{m^2}\) .

The distance between rhea and her friend's house could be 8 km and The distance of the library from the rocks house could be 15 km.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

rhea got a new e-scooter. She wanted to show it to her friend on the way to the library.

Her friend Ronan's house is due north of her house.

After showing him the new scooter she went to the library which is due west from rocks house.

while returning back she drove 17km diagonally to her house.

By Pythagoras' theorem

|AC|^2 = |AB|^2 + |BC|^2    

Here we can assume that

AB = The distance between rhea and her friend's house.

BC = The distance of the library from rocks house.

The triplet of the 17 would be (8, 15, 17)

So, we can say that the AB could be 8 km and BC could be 15 km or vice versa.

The generating function for the sequence {an} is given by a(x) = (1 + 2x) / (1 - x - 6x^2). It captures the terms of the sequence {an} as coefficients of the powers of x.

To find the generating function of the sequence {an}, we can use the properties of generating functions and solve the given recurrence relation.

The given recurrence relation is: an = an-1 + 6an-2

We are also given the initial conditions: a0 = 1 and a1 = 3.

To find the generating function, we define the generating function A(x) as:

a(x) = a0 + a1x + a2x² + a3x³ + ...

Multiplying the recurrence relation by x^n and summing over all values of n, we get:

∑(an × xⁿ) = ∑(an-1 × xⁿ) + 6∑(an-2 × xⁿ)

Now, let's express each summation in terms of the generating function a(x):

a(x) - a0 - a1x = x(A(x) - a0) + 6x²ᵃ⁽ˣ⁾

Simplifying and rearranging the terms, we have:

a(x)(1 - x - 6x²) = a0 + (a1 - a0)x

Using the given initial conditions, we have:

a(x)(1 - x - 6x²) = 1 + 2x

Now, we can solve for A(x) by dividing both sides by (1 - x - 6x^2²):

a(x) = (1 + 2x) / (1 - x - 6x²)

Therefore, the generating function for the given sequence is a(x) = (1 + 2x) / (1 - x - 6x²).

The relation between ages of all people in the world can be classified as a non-functional relation or a many-to-many relation, as multiple people can have the same age and age can vary among individuals.

The relation between ages of all people in the world can be classified as a non-functional relation because there can be multiple people with the same age. In other words, one age value (input) does not uniquely determine a single person (output). For example, there can be multiple individuals who are 25 years old. Additionally, age can vary among individuals, meaning that different people can have different ages. This variability further supports the notion of a non-functional relation.

One minute has 60 seconds. So we want to know if the car can travel 200 meters in 1 second, how far can it go in 60 seconds?

The speed in meters per minute is 12,000

The most appropriate statement that expresses a possible relationship between the variables, rate of pedaling and speed of a bicycle, is option A: "As the rate of pedaling increases, the speed of a bicycle increases."

This statement suggests that there is a positive correlation between the rate of pedaling and the resulting speed of the bicycle. When a cyclist pedals faster, it generates more force and power, translating into increased speed. This relationship aligns with basic principles of physics, as a greater input of energy and effort through pedaling leads to a higher velocity or speed output.

Option B implies that decreasing bicycle speed necessitates an increase in the rate of pedaling, and option C indicates that increasing bicycle speed is associated with a decrease in the rate of pedaling.

The formula of the determinant of a general n x n matrix Vn, can be derived using mathematical induction, elementary row operations, and cofactor expansion as follows:

Base caseFor the 1x1 matrix V1 = [α], its determinant is simply α, which can be obtained by cofactor expansion as follows: |α| = αInductive stepSuppose that the formula holds for all (n-1)x(n-1) matrices. We want to show that it holds for all nxn matrices.

Vn = [a11 a12 ... a1n;a21 a22 ... a2n;...;an1 an2 ... ann]For each row i, let Vi,j be the (n-1)x(n-1) matrix obtained by deleting the ith row and the jth column. Then, using the definition of the determinant by cofactor expansion along the first row, we have:

|Vn| = a11|V1,1| - a12|V1,2| + ... + (-1)n-1an,n-1|V1,n-1| + (-1)n an,n|V1,n|

For the ith term of the sum,

we have:

|Vi,j| = (-1)i+j|Vj,i|,

which can be shown using cofactor expansion along the ith row and jth column and applying mathematical induction:

For the base case of the 2x2 matrix V2 = [a11 a12;a21 a22],

we have:

|V2| = a11a22 - a12a21 = (-1)1+1a22|V2,1| - (-1)1+2a21|V2,2| - (-1)2+1a12|V2,3| + (-1)2+2a11|V2,4|

= a22|V1,1| + a21|V1,2| - a12|V1,3| + a11|V1,4|

For the inductive step, assume that the formula holds for all (n-1)x(n-1) matrices. Then, for any 1 <= i,j <= n,

we have:

|Vi,j| = (-1)i+j|Vj,i|

Therefore, we can express the determinant of Vn as:

Answer:

She would arrive 1 hour earlier than originally planned

Step-by-step explanation:

20 times 50 = 1000

this is the number of miles that Reena would travel at the speed of 50 mph for 20 hours.

If she drives 60 mph for the first 5 hours, she has so far driven 300 miles.  if she travelled 50 mph for the remained of the trip, we can figure out the amount of time she spent in this period by diving the remainder of 1000 - 300 = 700 by 50.

700/50 = 14

14 + 5 = 19

20 - 19 = 1

The probability that the moderate number of moths in 60 traps is more significant than 0.4 is approximately 0.9738 or 97.38%.

(a).

The mean number of moths =  60 traps

Now, the properties of normal distribution and central limit theorem are used.

mean of the individual moth counts = 0.5.

The standard deviation = the Standard deviation of the individual moth counts, divided by the square root of the sample size.

standard deviation = (0.7 / \(\sqrt{60}\))

standard deviation = 0.0905

the mean number of moths and standard deviation of the average number of moths in 60 traps are 0.5 and 0.0905.

(b) .

By using the central limit theorem

The average number of moths in 60 traps = 0.4

The z-score formula is to be calculated by using:

Z = (sample mean - population mean) / (standard deviation/sqrt (sample size))

Substituting the given values, we have:

Z = (0.4 - 0.5) / (0.7 / sqrt(60))

Z = -1.94

The probability of a Z-score greater than -1.94 is approximately 0.9738.

Hence, we can conclude that the probability that the average number of moths in 60 traps is greater than 0.4 is approximately 0.9738.
