The statement " data analytics often use samples rather than the full population of transactions." is False. So, option b is correct.

Option "a)" explains how data analytics can be used to test internal controls that are designed to prevent or detect fraud. These controls include processes and procedures that are put in place to ensure the accuracy and reliability of financial information and to detect any irregularities that may indicate fraud.

Option "c)" highlights how data analytics can detect small frauds before they become material. This is because data analytics can identify unusual patterns of behavior that may be indicative of fraud, even if the amounts involved are relatively small.

Option "d)" is incorrect because it states that all of the above options are ways data analytics are useful for detecting fraud. This is not entirely accurate because option "b" states that data analytics often use samples rather than the full population of transactions, which is not necessarily a beneficial aspect for detecting fraud.

The nightly rate that will maximize the nightly revenue is $200. The maximum revenue is $39,000.

What is revenue?

Revenue in accounting refers to the total amount of money made from the sale of products and services that are essential to the company's core operations. Sales or turnover are other terms used to describe commercial revenue. Some businesses make money from royalties, interest, or other fees.

The number of rooms in the hotel is 250.

80% of the hotel room occupied.

The number of occupied rooms is 250 × 80% = 200.

The nightly rate is $190.

The total rent is 200 × $190 = $38,000.

If each $10 increase in the rate results in 5 fewer occupied rooms.

The new rent is $190+10 = $200.

The number of occupied rooms is (200 - 5) = 195

The total rent is  $200 × 195 = $39,000.

The maximum revenue is $39,000.

Answer:

you need 221.2 ml of the 64% and 5308.8ml of the 29%

Step-by-step explanation:

the formula is (% x v)=(% * v)+(% * v)

so

(0.3 * 5530)=(0.64 * x)+(0.29 * (5530-x))

simplify

1,659= 0.64x + 1,603.7 - 0.29x

1,659=0.35x + 1,603.7

subtract 1603.7 from both sides

55.3=0.25x

divide 0.25 from both sides

221.2=x

subtract

5530-221.2

The main impact of increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).

This is because the standard deviation is a measure of the spread of the data, and the wider the spread, the wider the confidence interval will be. Mathematically, this can be shown by the following calculation:

The confidence interval is usually given by the formula:

where x is the mean of the sample, z is the z-score representing the confidence level, sigma is the standard deviation, and n is the sample size.

In this case, let's assume that x = 10, z = 1.96 (95% confidence interval), and n = 10. Then, when the standard deviation is 3.1, the confidence interval is 10 +/- (1.96*3.1/sqrt(10)) = 10 +/- 0.62, or (9.38, 10.62).

However, when the standard deviation is increased to 5.8, the confidence interval becomes 10 +/- (1.96*5.8/sqrt(10)) = 10 +/- 1.12, or (8.88, 11.12).

Therefore, increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).

The difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.

The variability in golf scores for players on the LPGA Tour and the PGA Tour can be measured using the standard deviation. To calculate the standard deviation, the squared differences between each score and the mean score must be calculated and then averaged. Then, the square root of this average must be taken.

Formula:

Standard Deviation =√((x1–μ)2+(x2–μ)2+...+(xn–μ)2)/n

Where:

x1, x2, ..., xn are the individual observations

μ is the mean

n is the number of observations

In this case, the sample of tournament scores from LPGA events showed a standard deviation of strokes and the sample of tournament scores from the PGA Tour showed a standard deviation of strokes. The difference between the two standard deviations can then be calculated by subtracting the LPGA standard deviation from the PGA standard deviation.

Therefore, the difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.

The solution is The perimeter of the sector is :30.5 cm

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

here, we have,

Mathematically, we have the area of the sector as;

e/360 * pi * r^2

r is 8 cm

so we have

58 = e/360 * pi * 8^2

58/64 * 360/pi = e

e = 103.85

To get the perimeter,

we have length of the arc plus 2r

Length of the arc is;

e/360 * 2 * pi * r

add 2 r;

e/360 * 2 * pi * r + 2r

so we have

103.85/360 * 2 * pi * 8 + 2(8)

= 14.5 + 16

Sum of angles in a straight line is 180°. Thus;

∠CAB = 180 - 104

∠CAB = 76°

The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

I have to flip the coin 16 times to say that I am 95% confident the coin is unfair.

This question can be answered using the binomial distribution. If we assume the coin is fair, then each flip of the coin has a 50% chance of coming up heads. We can use the binomial distribution to calculate the probability of getting heads at least 95% of the time.

For this calculation, we need to know the number of trials, n. We can use the formula: n = (1.96^2)/(p(1-p)) to calculate n for a 95% confidence level. In this case, p = 0.5, so n = 15.84. Since this is not a whole number, we can round up to 16 flips.

We have,

The coordinates of the endpoints are (a, b) = [tex](x_1, y_1)[/tex] and (-3, -5) = [tex](x_2, y_x)[/tex].

The distance between the two endpoints is 11 units.

Now,

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

11 = [tex]\sqrt{(-3 - a)^2 + (-5 - b)^2}[/tex]

Squaring both sides.

11² = (-3 - a)² + (-5 - b)²

121 = (-3 - a)² + (-5 - b)²

If we take a = -3 and b = 6

121 = (-3 + 3)² + (-5 - 6)²

121 = 0 + (-11)²

121 = 121
