statistical or nonstatistical What's the difference? is that statistical is of or pertaining to statistics while nonstatistical is not statistical.
Statistical sampling is more objective and uses probability to determine the appropriate sample size. While it is does not eliminate sampling risk, statistical sampling allows the auditor to measure sampling risk and take steps to control it. Nonstatistical sampling relies more on the auditor's judgment.

max and orlena bought 23 acres of land for $110,400. they bought some of the acres at $4000 per acre and some at $6300 per acre. how many acres did they buy at each price?
They bought 15 acres at $ 4000 per acre and 8 acres at $6300 per acre
Let,
They bought x acres at $ 4000
and ( 23-x ) acres at $ 6300
From information,
By using algebra,
4000x + 6300(23-x) = 110,400
4000x - 6300x+ 144900 = 110,400
-2300x = 110,400-144900
- 2300x = - 34500
x =34500 /2300
x = 15
x = 15
They bought 15 acres at $ 4000 per acre
(23 - 15 ) = 8 acres at $6300 per acre
Hence, they purchased 8 acres for $6300 per acre and 15 acres for $4,000 each.

you roll a six-sided die 20 times. what is the probability of having exactly 8 rolls land on a number greater than 4?
The probability of getting a number greater than 4 when the dice is rolled 20 times is 7.
The number on dice greater than 4 is 2 (that is 5 and 6 on dice) thus the probability of getting a number greater than 4 is
P = 2/6
P = 1/3
This is the probability if the dice were rolled once but if the dice were rolled 20 times thus the probability, in this case, needs to be multiplied by 20
P = 1/3*20
P = 6.66

Answer: 4683
Step-by-step explanation:
To have an odd number, and since the only odd number you have in your list is 3, that would be in the one's place. Then, you have to put the smallest number (except for 3) in the front. Now, you have two more places to fill in (4 _ _ 3). Like the 4, put the 6 after the 4 to have the smallest possible hundreds place. Now place the eight. Your final number should be... 4683.
when playing yahtzee, you roll five regular 6-sided dice. how many different outcomes are possible from a single roll? the order of the dice does not matter.
Answer:
6
Step-by-step explanation:
Which answer is correct?
(A)4x + y = 6
−2x + y = −5
(B)x + y = 8
2x − 9y = 4
(C)x − 4y = −6
−2x − y = 5
(D) −x + y = 9
9x + 2y = 4
The system of equations best represented by the graph are 4x + y = 6 and −2x + y = −5
How to determine the system of equations represented by the graph?The solution of the equations plotted in the graph can be found by checking the point of intersection of the lines
By examining the given graph we can guess the x and y values of the point of intersection. We need to guess because we do not have a means of getting the exact value from the graph. I guess x = 1.9 and y = -1.4
In order to find the system of equations represented by the graph, we need to solve the equations given in the option and check which one gives us x and y values close to what we guessed from the graph
By Solving 4x + y = 6 and −2x + y = −5:
4x + y = 6 (1)
−2x + y = −5 (2)
Using elimination, subtract (2) from (1), this gives:
6x = 11
x = 11/6 = 1.83
Put x = 11/6 into (1):
4(11/6) + y = 6
y = 6 - 4(11/6)
y = 6 -44/6 = -4/3 = -1.33
Since these calculated values are very close to the guessed values
Therefore, 4x + y = 6 and −2x + y = −5 are the system of equations best
represented by the graph. So option A is the answer

In triangle ABC, what is the measure of angle C if A = 120°, a = 25, and b = 20? Round the answer to the nearest hundredth.
The angle C = 103.85° using the sine rule and rounded to the nearest hundredth.
What is the sine rule?In trigonometry, the sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Considering the ∆ABC, the sine rule states that;
(a/sinA) = (b/sinB) = (c/sinC)
so
25/sin120° = 20/sinB
sinB = (20 × sin120°)/25 {cross multiplication}
sinB = 0.6928
B = sin^(-1)[0.6928)] {sine inverse}
B = 43. 85°
Sum of interior angles in ∆ABC is 180° so;
C = 180° - (120° + 43.85°)
C = 180° - 76.15°
C = 103.85°
With the application of the sine rule, we can conclude that the value of the angle C is 103.85° rounded to the nearest hundredth.

Using the concepts of co-ordinate geometry, we got that (1.14,3.17) is best set of co-ordinates for the equipment staging if art contractors must locate an equipment staging area to serve the three construction sites, located at (x,y) coordinates (0,3), (1,4) and (5,5).
So, for x co-ordinates how we can find the output, for this we need to find that co-ordinate in which stagging area is maximum.
So that co-ordinate is given = [x-coordinate of point A + x-co-ordinate of point y)/2.0]-1.36
=>the best x-co-ordinate is =[(0+5)/2.0]-1.36
=>the best x-co-ordinate is =1.14,
Similarly, for the y-co-ordinate
the best y-co-ordinate is given by =[[y-co-ordinate of point A+ y-co-ordinate of point B]/2.0] +0.67
=>the best y-co-ordinate is given by =[(0+5)/2/0]+0.67=2.5+0.67
=>the best y-co-ordinate is given by=(
Therefore, the best x and y co-ordinate is (1.14,3.17)
Hence, when art contractors locate an equipment staging area to serve three construction sites, located at (x,y) coordinates (0,3), (1,4) and (5,5). traffic between the staging area and each of the sites is 30 trips a week, except for the site located at (5,5), which is only 10 trips a week. the best set of co-ordinates for the equipment staging area is (1.14,3.17).

A school had 1 200 students last year and only 1 080 students this year. What was the percent decrease in the number of students?
The percentage decrease in the number of students in the school was 10%.
What is the percentage?The percentage refers to the ratio or proportion of students that reduced the number of the school population for the present year in comparison to last year's.
We can compute the percentage by finding the decrease in population and taking the result as a numerator of the total number in the last year and multiplying the result by 100.
Percentages represent fractional values and are usually depicted by the percentage sign (%).
The total number of students in the school last year = 1,200
The total number of students in the school this year = 1,080
The decrease in the number of students = 120 (1,200 - 1,080)
The percentage decrease = 10% (120/1,200 x 100)

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Bill without tax = 105.73
Tax = 6%
So, bill amount after tax = 105. 73 + 105. 73 x 6/100
= 105.73 + 6.3438
= $112.0738
Addition of 20% tip = 112.0738 + 211.46 = $323.5338.

passes through A (2, "-5)" parallel to BC with (1, 3) and ( 4, 5) PLS HURRRY!!!!!
The equation for the linear equation parallel to BC is:
y = (2/3)*x - 19/3
How to get the linear equation?
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
slope = (y2 - y1)/(x2 - x1)
And two lines are parallel if both lines have the same slope and different y-intercept.
So if we want to et a line parallel to BC whose endpoints are (1, 3) and ( 4, 5), the slope should be:
slope = (5 - 3)/(4 - 1) = 2/3
So our line is like:
y = (2/3)*x + b
And this must pass through (2, -5)
Replacing these values we get:
-5 = (2/3)*2 + b
-5 - 4/3 = b
-15/3 - 4/3 = b
-19/3 =b
Then the linear equation is:

The new odds that the box picked is a special one is 4
Since, there are four boxes that look the same. in one box (the special one), half of the marbles are blue. but only 1/8 of the marbles in the other boxes are blue.
We will have this hypothesis:
The box the blue marble was picked from is the special box.
Prior confidence we had:
Ratio of special boxes to non special boxes=1:3
Now P(blue &special)=1/2, given that a box is selected from the special box, there is 1/2 chance that it is blue
And P(blue & not special)=1/8, given that a box is selected from a non-special box, there is 1/8 chance that it is blue
According to Baye's factor ,we get:
