If the forecast for two consecutive periods is 1,500 and 1,400 and the actual demand is 1,200 and 1,500 , then the mean absolute deviation is 1) 500 2) 700 3) 200 4) 100
200 is the mean absolute deviation. Therefore, choice three (200) is the right one.
How to calculate the mean absolute deviation
The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.
Forecasted values are as follows: 1,500 and 1,400
Values in actuality: 1,200 and 1,500
Absolute differences:
|1,500 - 1,200| = 300
|1,400 - 1,500| = 100
Now, we calculate the MAD:
MAD = (300 + 100) / 2 = 400 / 2 = 200
Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

Compute Hometown Property Casualty Insurance Company's combined ratio
after dividends using its data as follows:
Loss Ratio 75%
Expense Ratio,30%
Dividend Ratio 1%
Net Investment income 8%
Hometown Property Casualty Insurance Company's combined ratio, after dividends, can be calculated as 114%. This means that the company is paying out more in losses, expenses, dividends, and taxes than it is earning in premiums and investment income.
The combined ratio is a key metric used in the insurance industry to assess the overall profitability of an insurance company. It is calculated by adding the loss ratio and the expense ratio. In this case, the loss ratio is 75% and the expense ratio is 30%. Therefore, the combined ratio before dividends would be 75% + 30% = 105%.
To calculate the combined ratio after dividends, we need to consider the dividend ratio and the net investment income. The dividend ratio is 1%, which means that 1% of the company's premium revenue is paid out as dividends to shareholders. The net investment income is 8%, representing the return on the company's investments.
To adjust the combined ratio for dividends, we subtract the dividend ratio (1%) from the combined ratio before dividends (105%). This gives us 105% - 1% = 104%. Then, we add the net investment income (8%) to obtain the final combined ratio.
Therefore, the combined ratio after dividends for Hometown Property Casualty Insurance Company is 104% + 8% = 114%. This indicates that the company's expenses and losses, including dividends and taxes, exceed its premium revenue and investment income by 14%. A combined ratio above 100% suggests that the company is operating at a loss, and in this case, Hometown Property Casualty Insurance Company would need to take measures to improve its profitability.

the perimeter of a triangle is 23 cm. all the side lengths are integers. if one side measures 5 cm, what is the length of the largest possible side?
The largest possible side is 11 cm
The perimeter of any two-dimensional figure is defined as the distance around the figure. We can calculate the perimeter of any closed shape just adding up the length of each of the sides.
The sum of the lengths of the sides is the perimeter of any polygon. In the case of a triangle,
Perimeter = Sum of the three sides
he formula for the perimeter of a closed shape figure is usually equal to the length of the outer line of the figure. Therefore, in the case of a triangle, the perimeter will be the sum of all the three sides. If a triangle has three sides a, b and c, then,
Perimeter, P = a + b +c
perimeter of a triangle is 23 cm.
therefor , P = 23 cm.
one side measures 5 cm,
a = 5 cm
Perimeter,
P = a + b +c
23 = 5 + b + c
23 - 5 = b + c
b + c = 18
The sum of any 2 sides of a triangle is greater than the third side.

Write the event as set of outcomes. We flip three coins and obtain more tails than heads.
A. {ttt}
B. {ttt, tth, tht, htt}
C. {ttt, tth}
D. {tth, tht, htt}
Answer:
B.
Step-by-step explanation:
All the possible outcomes are listed on choice B.
The event is a set of outcomes. if we flip three coins and obtain more tails than heads is E = {ttt, tth, tht, htt} option (B) is correct.
What is set?A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
We have three coins.
As we know, in a coin there are two sides head and a tail.
If we flip three coins then the set of all the possible outcomes:
O = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
The set of outcomes has more tails than heads.
E = {ttt, tth, tht, htt}
We can find the probability, the probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Probability = 4/8 = 1/2
Thus, the event is a set of outcomes. if we flip three coins and obtain more tails than heads is E = {ttt, tth, tht, htt} option (B) is correct.

if a snowball melts so that its surface area decreases at a rate of 1 cm min, find the rate at which the diameter decreases when the diameter is 10 cm.
The rate at which the diameter decreases when the diameter is 10 cm is -0.00798 cm/min.
To find the rate at which the diameter decreases, we can use the relationship between the surface area and the diameter of a sphere.
The surface area of a sphere is given by the formula:
A = \(4\pi r^2\), where A is the surface area and r is the radius (which is half the diameter).
Differentiating both sides of the equation with respect to time t, we get:
dA/dt = 8πr(dr/dt).
We are given that the surface area decreases at a rate of \(1 cm^2/min\), so dA/dt = \(-1 cm^2/min\). We want to find dr/dt when the diameter is 10 cm, which means the radius is r = 10/2 = 5 cm.
Substituting these values into the equation, we have:
-1 = 8π(5)(dr/dt).
Simplifying, we get:
-1 = 40π(dr/dt).
Now, solving for dr/dt:
dr/dt = -1 / (40π).
Using a calculator, this evaluates to approximately -0.00798 cm/min.
Therefore, when the diameter is 10 cm, the rate at which the diameter decreases is approximately -0.00798 cm/min. Note that the negative sign indicates the decrease in diameter.

A medical equipment industry manufactures X-ray machines. The unit cost (the cost in dollars to make each X-ray machine) depends on the number of machines made. If machines are made, then the unit cost is given by the function . What is the minimum unit cost?Do not round your answer.
Answer:
$14,362
Step-by-step explanation:
The computation of the minimum unit cost is shown below:
Given that
0.6x^2 - 108x + 19,222
And as we know that the quadratic equation form is
ax^2 + bx + c
where
a = 0.6
b = -108
c = 19,222
Now for determining the minimal cost we applied the following formula which is
\(= \frac{-b}{2a} \\\\ = \frac{-(-108)}{2\times 0.6} \\\\ = \frac{108}{1.2}\)
= 90
Now put these values to the above equation
\(= 0.6\times 90^{2} - 108 \times 90 + 19,222\)

write the number 180 as a sum of three numbers so that the sum of the products taken two at a time is a maximum. (enter the three numbers as a comma-separated list.)
The maximum sum of the products taken two at a time is 180, and this can be achieved by choosing 60, 60, and 60 as the three numbers.
In order to write the number 180 as a sum of three numbers so that the sum of the products taken two at a time is a maximum, one way to do it is to use the formula:
\((x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + xz + yz)\)
Let the three numbers be x, y, and z.
Then the product of the numbers taken two at a time is: \(xy + xz + yz\)
If we want to maximize the sum of the products taken two at a time, we need to maximize \(xy + xz + yz\).
In the formula: \((x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + xz + yz)\)
We can see that the first three terms on the right-hand side are fixed since they depend on x, y, and z. Therefore, to maximize the sum of the products taken two at a time, we need to maximize 2(xy + xz + yz). Since we have the number 180, we can let: \(x + y + z = 180\)
Then, we need to maximize: 2(xy + xz + yz) Using calculus, we can find that the maximum value of 2(xy + xz + yz) is attained when: \(x = y = z = 60\)
Therefore, the three numbers that can be used to write the number 180 as a sum of three numbers so that the sum of the products taken two at a time is a maximum are: 60, 60, 60.

What is a right-angled triangle?
A triangle is said to have a right angle if one of the angles is 90 degrees. Right triangles are those with angles at 90 degrees, which are referred to as right angles.
The diagram shows a right-angled triangle with opposite = 12 units and hypotenuse as 54 units.
To find the angle x, apply the formula -
sin(x) = opposite/hypotenuse
sin(x) = 12/54
x = sin^-1(12/54)
x = sin^-1(2/9)
x = 12.84°
Rounding it to nearest tenth gives x = 12.8°.

How much time will it take your savings to double in value if the interest rate is 3%? What if the interest rate was 8%? Compute both answers by applying the "Rule of 72." Show all work
For an interest rate of 8%, we divide 72 by 8: 72 / 8 = 9. Thus, it would take around 9 years for the savings to double at an interest rate of 8%.
The "Rule of 72" is a quick estimation method to determine the time it takes for an investment or savings to double in value. By dividing 72 by the interest rate, you can obtain an approximation of the doubling time. For an interest rate of 3%, it would take approximately 24 years for the savings to double. For an interest rate of 8%, it would take around 9 years for the savings to double.
To calculate the doubling time using the Rule of 72, divide 72 by the interest rate. This provides an approximation of the number of years it takes for an investment or savings to double in value.
For an interest rate of 3%, we divide 72 by 3: 72 / 3 = 24. Therefore, it would take approximately 24 years for the savings to double.
For an interest rate of 8%, we divide 72 by 8: 72 / 8 = 9. Thus, it would take around 9 years for the savings to double at an interest rate of 8%.

A new car is purchased for 15600 dollars. The value of the car depreciates at 12. 25% per year.
To find the time it will be until the value of the car is 2700 dollars , we used the formula,
A = P (1 - r%)ⁿ
Here, A = 2700 dollars
P = 15600 dollars
r = 12.25% = 0.1225
Substitute all the values, we get;
2700 = 15600 (1 - 0.1225)ⁿ
0.17 = (0.88)ⁿ
