A company has actual unit demand for three consecutive years of 124, 126, and 135. The respective forecasts for the same three years are 120, 120, and 130. Which of the following is the resulting MAD value that can be computed from this data? A. 3 B. 5 C. 15 D. 123
Answer:
B. 5
Step-by-step explanation:
Computation for Which of the following is the resulting MAD value that can be computed from this data
Using this formula
MAD Value=[(Actual unit demand-Respective forecasts)/Number of years]
Let plug in the formula
MAD Value = [(124 - 120) + (126 - 120) + (135 - 130)]/3 years
MAD Value =(4+6+5)/3 years
MAD Value = 15/3 years
MAD Value = 5
Therefore the MAD value that can be computed from this data is 5

Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67

Please find the complete question and the graph in the attached file.
[tex]\to \frac{12}{l}= \frac{5.5}{l-x}\\\\\to 12(l - x) = 5.5l\\\\\to 12l - 12x = 5.5l\\\\\to 12l -5.5l = 12x\\\\\to 6.5l =12x\\\\\to 12x = 6.5l \\\\\to x = ( \frac{6.5}{12})l \\\\[/tex]
Calculating the Derivative of the above value:
[tex]\to \frac{dx}{dt} = (\frac{6.5}{12}) \frac{dl}{dt}\\\\\to \frac{dl}{dt} = (\frac{12}{6.5}) \frac{dx}{dt}\\\\\to \frac{dx}{dt} = 2 \\\\ \to \frac{dl}{dt} = ( \frac{12}{6.5} \times 2)[/tex]
[tex]=\frac{24}{6.5} \\\\= \frac{48}{13} \ \frac{ft}{sec}[/tex]

Consider the systems of equations below.
System A)
X^2 + y = 17
Y = -1/2x
System B)
Y = x^2 - 7x + 10
Y = -6x + 5
System C)
Y = -2x^2 + 9
8x - y = -17
Determine the number of real solutions for each system of equations.
System A) ____
SystemB) ____
System C) ____
Based on the systems of equations given, the number of real solutions for each system is:
System A - 2 solutions. System B - 0 solutions. System C - 1 solution. How many solutions will the systems of equations give?To find out the number of solutions, you should plot the equations on a graph.
When system A is plotted as shown attached, you notice that line y = 1/2x intersects x² + y² = 17 twice. It therefore has two solutions.
When system B is plotted, y = -6x + 5 does not intercept y = x² + 7x + 10 which means that there are no real solutions.
System C shows only one real solution because 8x - y = -17 intercepts y = -2x² + 9 once.

Angle A and Angle B are supplementary angles. If the measure of angle A = (6x + 10)° and the measure of angle B = (4x +30), then find the measure of angle B.
Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°

Give GHJ=XJZ find each missing measure
Answer/Step-by-step explanation:
Given that ∆GHJ is congruent to ∆XYZ, this:
<G = <X,
<H = <Y = 38°
<J = <Z,
GH = XY = 27 ft
HJ = YZ = 27 ft (two sides of an isosceles ∆ are the same)
GJ = XZ = 18 ft
a. GJ = 18 ft
b. XY = 27 ft
c. ZY = 27 ft
d. m<H = m<Y (corresponding angles)
m<H = 38° (substitution)
e. m<Z = (180 - 38)/2 (base triangles of an isosceles ∆ are equal)
m<Z = 142/2
m<Z = 71°
f. m<J = m<Z (corresponding angles)
m<J = 71° (substitution)

A study conducted on American families shows that 18% of these families have medical bills of more than $10,000. Find the probability that among 5 randomly selected American families, at least one has medical bills of more than $10,000.
Answer:
the probability is 0.6293
Step-by-step explanation:
The computation of the probability is shown below:
Given that
n = 5
P = 0.18
As it represents the binomial distribution
P(X = x) = [tex]^NC_x[/tex]× p^x × (1 - p) ^(n - x)
P(X > 1) = 1 - P(X < 1)
= 1 - P(X = 0)
= 1 - ( [tex]^5C_0[/tex]× (0.18) ^0 × (0.82) ^5)
= 1 - 0.3707
= 0.6293
hence, the probability is 0.6293

A certain forest covers an area of 4000km squared. Suppose that each year this area decreases by 3.75percent. What will the area be after 14 years
Answer:
After 14 years, the area will be 2342.4 km squared.
Step-by-step explanation:
Since the area is decreasing, we can use the decaying exponential function
[tex]y = A(1 - r)^{t}[/tex]
where
A represents the initial area.r represents the rate at which the area changest is the time periodGiven
Initial Area A = 4000 km squared
Rate r = 3.75% = 3.75/100 = 0.0375
Time period t = 14
To Determine
The Area after 14 years = y = ?
Plug in the values in the formula
[tex]y = A(1 - r)^{t}[/tex]
[tex]y\:=4000\left(1\:-\:0.0375\right)^{14}[/tex]
[tex]y=4000\cdot \:0.9625^{14}[/tex]
[tex]y=2342.4[/tex] km squared
Therefore, after 14 years, the area will be 2342.4 km squared.

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.
The nth term of an arithmetic sequence.
= a + (n - 1)d
The 61st term of the sequence is 85.
What is an arithmetic sequence?
It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8 is an arithmetic sequence.
We have,
-5, -7/2, -2, -1/2, 1
a = -5
d = -7/2 + 5
d = 3/2
Now,
The nth term of an arithmetic sequence.
= a + (n - 1)d
Now,
n = 61
61st term:
= -5 + (61 - 1)(3/2)
= -5 + 60 x 3/2
= -5 + 30 x 3
= -5 + 90
= 85
Thus,
The 61st term of the sequence is 85.

Which can be used to prove angle 3 is congruent to angle 6
Answer:
alternate interior angle
Step-by-step explanation:
A boat travels at a rate of 18 kilometers per hour from its port. A second boat is 34 kilometers behind the
first boat when it starts traveling in the same direction at a rate of 22 kilometers per hour to the same port.
Let d represent the distance the boats are from the port in kilometers and t represent the amount of time
in hours. The system of equations ⎧
⎨
⎩
d = 18t + 34 d = 22t
can be used to represent this situation. How many
hours will it take for the second boat to catch up to the first boat? How far will the boats be from their
port? Use the substitution method to solve this real-world application.
The number of hours taken should be 8.5 hours
And, the distance should be 187 km.
Important information:The equation is d = 18t + 34 and d = 22t.The calculation is as follows:d = 18t + 34
d = 22t
Put the d value in the above equation
22t = 18t + 34
22t - 18t = 34
4t = 34
t = 8.5 hours
Now the distance is
= 22(8.5)
= 187 km
