Answer:
a) The DSO decreases.
Step-by-step explanation:
DSO is short for Days Sales Outstanding and it is a measure of how quickly a company can convert its accounts receivable to cash. A company is described as strong when it has enough cash flow and this can be achieved by reducing the length of days within which accounts receivable can be converted to cash.
For the company to achieve a lowered DSO, it must ensure that customers with bad or low credit ratings are not allowed, or reasonably reduced in the business. The accounting and payment procedures must also be checked to be expedient so that delays in payment procedures would be reasonably reduced.

What is the cost of x students paying tuition of $2800 each?
Answer:
$2800[tex]x[/tex]
Step-by-step explanation:
Tuition fee per student = $2800/student
if there are [tex]x[/tex] amount of students, then the total costs of tuition that will be generated will be
([tex]x[/tex] students) x ($2800/student) = $2800[tex]x[/tex]
If for example, there are 200 students in this school, then in this case, [tex]x[/tex] = 200 students.
Total cost = (200 students) x ($2800/student) = $560000.
In simple terms, the cost of [tex]x[/tex] students paying tuition of $2800, is [tex]x[/tex] multiplied by the $2800 tuition for each student which is $2800[tex]x[/tex]

A number is 9 more than another number. Twice the sum of the two numbers is 10. Find the two numbers.
Answer:
7, -2
Step-by-step explanation:
we call the first number "X" and the second one "Y"
X is 9 more than Y! which means we need to add 9 to Y so it'll be equal to X. so: Y+9=X
also 2×(X+Y)=10
you can also write this down as: 2X+2Y=10
now we have:
X=Y+9
2X+2Y=10
you can now put what equals to X in the second Equation:
2(Y+9)+2Y=10 => 2Y+18+2Y=10 => 4Y=10-18 =>Y= -2
the only thing left to do is to put Y= -2 in the first equation:
X= -2+9 => X=7
An algebraic equation is an equation with unknown variables which can be represented using any number of the alphabet.
The two numbers are 7 and -2
Let's represent the unknown numbers which are the unknown variables with the letters
Let the first number = m
The second number = n
A number is 9 more than another number. This statement is represented by the algebraic equation:
m = 9 + n .......... Equation 1
Twice the sum of the two numbers is 10. This statement is represented by the algebraic equation:
2 (m + n) = 10
2m + 2n = 10...................Equation 2
We substitute 9 + n for "m" in Equation 2
2(9 + n) + 2n = 10
18 + 2n + 2n = 10
Subtract 18 from both sides
18 - 18 + 2n + 2n = 10 - 18
4n = -8
Divide both sides by 4
4n/4 = -8/4
n = -2
We solve for m using Equation 1
m = 9 + n
m = 9 + (-2)
m = 9 - 2
m = 7
Therefore, the two numbers are 7 and -2

Given an isosceles right triangle with side 6 m, what is the length of the hypotenuse?
Show work please
Answer: 6√2m or 8.49.
Step-by-step explanation:
Drawing the right angled triangle and label the sides, AC, which is the hypotenuse and the longest, AB , one if the sides, and BC the third sides. Since it is an isosceles right angle triangle with the right angle at B, based on my own diagram here, two of the sides are equal.
AB = BC = 6m
Now to find the hypotenuse, we apply the Pythagoras theorem which states that the square of the sum of the two sides equal the square of the hypotenuse side.That is
AC² = AB² + BC²
AC² = 6² + 6²
= 36. + 36
= 72
AC² = 72, Therefore, AC which is the hypotenuse
AC = √72
= √36 × √2
= 6√2m. or 8.49m

Between 9 AM and 10 AM one hundred airplanes departed from Newark Airport. Ten of the airplanes were delayed by an hour each. Of the remaining airplanes, half left on time and half were delayed by an average of 20 minutes. To the nearest whole minute, how long was the average flight delay
Answer:
27 minutes
Step-by-step explanation:
Given that :
Total number of planes = 100
10 planes were delayed by an hour each= 60 minutes;
Total delay time for the 10 planes = (60 * 10) = 600 minutes
Of the 90 remaining :
Half (45) left on time = no delay
(Delay2) : Half (45) experieced a average delay of 20 minutes.
Total delay time for the 45 planes = (45 * 20) = 900
Hence,
Overall delay time = (600 + 900) = 1500 minutes
Number of planes delayed = (10 +45) = 55 planes
Average flight delay :
(Overall delay time / number of planes delayed)
(1500 / 55) = 27.27
= 27 minutes ( to the nearest minute)

Solve the following System of Three Equations:
x−3y+z=−15
2x+y−z=−2
x+y+2z=1
Answer:
x = -3 , y = 4 , z = 0
Step-by-step explanation:
Solve the following system:
{x - 3 y + z = -15
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Choose an equation and a variable to solve for.
In the first equation, look to solve for z:
{x - 3 y + z = -15
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Solve for z.
Subtract x - 3 y from both sides:
{z = 3 y + (-x - 15)
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Perform a substitution.
Substitute z = -15 - x + 3 y into the second and third equations:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
x + y + 2 (-15 - x + 3 y) = 1
Hint: | Expand the left hand side of the equation x + y + 2 (-15 - x + 3 y) = 1.
x + y + 2 (-15 - x + 3 y) = x + y + (-30 - 2 x + 6 y) = -30 - x + 7 y:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
-30 - x + 7 y = 1
Hint: | Choose an equation and a variable to solve for.
In the second equation, look to solve for x:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
-30 - x + 7 y = 1
Hint: | Isolate terms with x to the left hand side.
Subtract 15 - 2 y from both sides:
{z = -15 - x + 3 y
3 x = 2 y - 17
-30 - x + 7 y = 1
Hint: | Solve for x.
Divide both sides by 3:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
-30 - x + 7 y = 1
Hint: | Perform a substitution.
Substitute x = (2 y)/3 - 17/3 into the third equation:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 - 73/3 = 1
Hint: | Choose an equation and a variable to solve for.
In the third equation, look to solve for y:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 - 73/3 = 1
Hint: | Isolate terms with y to the left hand side.
Add 73/3 to both sides:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 = 76/3
Hint: | Solve for y.
Multiply both sides by 3/19:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
y = 4
Hint: | Perform a back substitution.
Substitute y = 4 into the first and second equations:
{z = -x - 3
x = -3
y = 4
Hint: | Perform a back substitution.
Substitute x = -3 into the first equation:
{z = 0
x = -3
y = 4
Hint: | Sort results.
Collect results in alphabetical order:
Answer: {x = -3 , y = 4 , z = 0

Explanation:
Set A = {4,5,6,7,8,9} since these values are larger than 3 and smaller than 10. We only consider whole numbers in this range.
Set B = {1,2,3,4,5,6,7} represents positive whole numbers less than 8
To find the set [tex]A \cap B[/tex] we need to see which values are in both A and B at the same time. Those values are {4,5,6,7}
So [tex]A \cap B = \{4,5,6,7\}[/tex]
--------
side note: the notation [tex]A \cap B[/tex] means "A intersect B", so we're looking at where the two sets intersect or overlap (ie what they have in common).
Sebastian was in a hotel lobby and took the elevator up 7 floors to his room. Then he took the elevator down 9 floors to the parking garage. He described his movement with the expression 9+ (-7). What is Sebastian's error?
Answer:
Sebastian didn't interpret the numbers correctly (See explanation)
Step-by-step explanation:
If you go up an elevator, you are gaining floors, so the number is positive.
If you go down an elevator, you are losing floors, so the number is positive.
Looking at the statement, he went 7 floors up to his room, then 9 floors down to the parking garage this can be represented as [tex]7 - 9[/tex], since the 7 is positive and the 9 is negative.
Sebastian described the movement as [tex]9 + -7[/tex], which is wrong - 9 should be -9 and -7 should be 7.
Hope this helped!
Answer:
Step-by-step explanation:
Let the lobby level be the reference point for Seb's movement.
The following describes his motion: +7 - 9. This puts him 2 floors below the lobby level.
Seb's "9 + (-7)" is incorrect because it indicates an upward trip, whereas the actual direction was downward. Similarly, "-7" indicates a downward trip, whereas the action direction was upward.

Answer:
-2
Step-by-step explanation:
So we want to find the value of:
[tex](-6)+(4)[/tex]
Simply add:
[tex](-6)+4=-2[/tex]
Thus, drop the word SUM on -2.
Further notes:
To use the number line to solve, first start by placing your point on -6.
Since we are adding 4 to -6, we move to the right. Thus, move from -6 four spaces to the right.
If you do so correctly, you will end up at -2, the same answer we acquired previously.
Answer:
[tex]\Huge \boxed{-2}[/tex]
Step-by-step explanation:
The sum is the result from adding two or more numbers to each other.
[tex]-6 + 4 = - 2[/tex]
-6 is the starting point on the number line.
4 is added to -6, so an arrow from -6 goes 4 units to the right of the number line.
The arrow stops at -2.

Answer:
For x = 0, P(x = 0) = 0.35
For x = 1, P(x = 1) = 0.54
For x = 2, P(x = 2) = 0.11
For x = 3, P(x = 3) = 0
Step-by-step explanation:
We are given that the Sky Ranch is a supplier of aircraft parts. Included in stock are 6 altimeters that are correctly calibrated and two that are not. Three altimeters are randomly selected, one at a time, without replacement.
Let X = the number that are not correctly calibrated.
Number of altimeters that are correctly calibrated = 6
Number of altimeters that are not correctly calibrated = 2
Total number of altimeters = 6 + 2 = 8
(a) For x = 0: means there are 0 altimeters that are not correctly calibrated.
This means that all three selected altimeters are correctly calibrated.
Total number of ways of selecting 3 altimeters from a total of 8 = [tex]^{8}C_3[/tex]
The number of ways of selecting 3 altimeters from a total of 6 altimeters that are correctly calibrated = [tex]^{6}C_3[/tex]
So, the required probability = [tex]\frac{^{6}C_3}{^{8}C_3}[/tex]
= [tex]\frac{20}{56}[/tex] = 0.35
(b) For x = 1: means there is 1 altimeter that is not correctly calibrated.
This means that from three selected altimeters; 1 is not correctly calibrated and 2 are correctly calibrated.
Total number of ways of selecting 3 altimeters from a total of 8 = [tex]^{8}C_3[/tex]
The number of ways of selecting 2 correctly calibrated altimeters from a total of 6 altimeters that are correctly calibrated = [tex]^{6}C_2[/tex]
The number of ways of selecting 1 not correctly calibrated altimeters from a total of 2 altimeters that are not correctly calibrated = [tex]^{2}C_1[/tex]
So, the required probability = [tex]\frac{^{6}C_2 \times ^{2}C_1 }{^{8}C_3}[/tex]
= [tex]\frac{30}{56}[/tex] = 0.54
(c) For x = 2: means there is 2 altimeter that is not correctly calibrated.
This means that from three selected altimeters; 2 are not correctly calibrated and 1 is correctly calibrated.
Total number of ways of selecting 3 altimeters from a total of 8 = [tex]^{8}C_3[/tex]
The number of ways of selecting 1 correctly calibrated altimeters from a total of 6 altimeters that are correctly calibrated = [tex]^{6}C_1[/tex]
The number of ways of selecting 2 not correctly calibrated altimeters from a total of 2 altimeters that are not correctly calibrated = [tex]^{2}C_2[/tex]
So, the required probability = [tex]\frac{^{6}C_1 \times ^{2}C_2 }{^{8}C_3}[/tex]
= [tex]\frac{6}{56}[/tex] = 0.11
(d) For x = 3: means there is 3 altimeter that is not correctly calibrated.
This case is not possible, so this probability is 0.

Find all unit vectors that are orthogonal to the vector u = 1, 0, −4 .
Answer:
Step-by-step explanation:
Given:
u = 1, 0, -4
In unit vector notation,
u = i + 0j - 4k
Now, to get all unit vectors that are orthogonal to vector u, remember that two vectors are orthogonal if their dot product is zero.
If v = v₁ i + v₂ j + v₃ k is one of those vectors that are orthogonal to u, then
u. v = 0 [substitute for the values of u and v]
=> (i + 0j - 4k) . (v₁ i + v₂ j + v₃ k) = 0 [simplify]
=> v₁ + 0 - 4v₃ = 0
=> v₁ = 4v₃
Plug in the value of v₁ = 4v₃ into vector v as follows
v = 4v₃ i + v₂ j + v₃ k -------------(i)
Equation (i) is the generalized form of all vectors that will be orthogonal to vector u
Now,
Get the generalized unit vector by dividing the equation (i) by the magnitude of the generalized vector form. i.e
[tex]\frac{v}{|v|}[/tex]
Where;
|v| = [tex]\sqrt{(4v_3)^2 + (v_2)^2 + (v_3)^2}[/tex]
|v| = [tex]\sqrt{17(v_3)^2 + (v_2)^2}[/tex]
[tex]\frac{v}{|v|}[/tex] = [tex]\frac{4v_3i + v_2j + v_3k}{\sqrt{17(v_3)^2 + (v_2)^2}}[/tex]
This is the general form of all unit vectors that are orthogonal to vector u
where v₂ and v₃ are non-zero arbitrary real numbers.
[tex]\left ( \frac{1}{\sqrt{17}},0, \frac{-4}{\sqrt{17}}\right )[/tex]
A vector is a quantity that has both magnitude and direction.
Two vectors are said to be orthogonal if they are perpendicular to each other.
Unit vectors orthogonal to [tex]u=\left ( a,b,c \right )[/tex] are given by [tex]\left ( \frac{a}{\sqrt{a^2+b^2+c^2}},\frac{b}{\sqrt{a^2+b^2+c^2}},\frac{c}{\sqrt{a^2+b^2+c^2}} \right )[/tex]
So, vectors orthogonal to [tex]u=\left ( 1,0,-4\right )[/tex] are [tex]\left ( \frac{1}{\sqrt{1^2+0^2+(-4)^2}},\frac{0}{\sqrt{1^2+0^2+(-4)^2}},\frac{-4}{\sqrt{1^2+0^2+(-4)^2}} \right )[/tex]
[tex]\left ( \frac{1}{\sqrt{1^2+0^2+(-4)^2}},\frac{0}{\sqrt{1^2+0^2+(-4)^2}},\frac{-4}{\sqrt{1^2+0^2+(-4)^2}} \right )=\left ( \frac{1}{\sqrt{17}},0, \frac{-4}{\sqrt{17}}\right )[/tex]
So, unit vector orthogonal to [tex]u[/tex] is [tex]\left ( \frac{1}{\sqrt{17}},0, \frac{-4}{\sqrt{17}}\right )[/tex]

Each statement describes a transformation of the graph of F(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(x) - 3?
Answer: B) Shift 3 units down
Recall that y = f(x) as both describe outputs of a function. The same applies for g(x) as well. Saying f(x)-3 means y-3. So we're subtracting 3 from the y coordinate of each point. A point like (1,5) moves to (1,2). Doing this to all points on f(x) will move the entire curve down 3 units.
If f(x)= x and g(x) = x + 6, find g(f(o)).
Answer:

Step-by-step explanation:
f(x)= x
g(x) = x + 6,
g(f(o))
Let x = 0
f(0) = 0
