I was reading the comments from the other person who answered and I'm guessing both of you don't know what Mean Absolute Deviation (MAD) means.... I'm going to show you an example.......
For example:
2, 2, 4, 4
2 + 2 + 4 + 4 = 12 ÷ 4 = 3
12 ÷ 4 (because there are exactly 4 numbers)
Mean: 3
Mean Definition: The mean is the average of the numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.
Mean Absolute Deviation (MAD):
2, 2, 4, 4 Mean: 3
(2 - 3) + (2 - 3) + (4 - 3) + (4 - 3) = 4 ÷ 4 = 1
Mean Absolute Deviation: 1
4 ( because I subtracted all the numbers and then added it all together) ÷ 4 (because there are exactly 4 number)
I hope your getting it because if you do it on paper it's easier.
Hope these helps!!!! Happy Holidays!!!! (:
Cameron is playing 9 holes of golf. He needs to score a total of at most 13 over par on the last four holes to beat his best golf score. On the last four holes, he scores 7 over par, 3 under par, 8 over par, and 3 under par.
Cameron does beat his best score. He scores 7 and 8 over par, as well as 3 under par twice. This makes him have 7 + 8 or 15 over par and 3 + 3 or 6 under par. 15 - 6 = 9, which is under 13, his current best score.

A ceiling fan has five equally spaced blades find the angle of rotation the Maps one blade on to the adjacent blade
Answer:
A rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.
Step-by-step explanation:
We are told that a ceiling fan has 5 equally spaced blades. It will work as a regular pentagon.
We can find angle of rotation to map one blade on adjacent blade dividing 360 by 5 as sum of angles of regular pentagon equals to 360 degrees.
[tex]\text{ Angle of rotation}=\frac{360}{5}[/tex]
Upon dividing 360 by 5 we will get,
[tex]\frac{360}{5} =72[/tex]
Therefore, a rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.
The angle between adjacent blades in a five-blade ceiling fan is b. 72°.
Step 1 :**Understanding the Situation**:
We have a ceiling fan with five equally spaced blades. We need to find the angle of rotation that maps one blade onto the adjacent blade.
Step 2 :**Identifying the Angle between Blades**: Since the blades are equally spaced, we can find the angle between adjacent blades by dividing the full circle (360°) by the number of blades, which is 5.
[tex]\[ \text{Angle between adjacent blades} = \frac{360°}{5} = 72° \][/tex]
Step 3 :**Checking the Options**:
- (a) 144° is twice the angle between adjacent blades. This would correspond to skipping one blade and landing on the third blade, which is not adjacent.
- (b) 72° is the same as the angle between adjacent blades. This seems promising.
- (c) 90° is not consistent with the division of the circle by the number of blades.
- (d) 36° is half the angle between adjacent blades. This would correspond to a situation where we skip two blades, which is not adjacent.
Complete Question :

In 1 hour how many more times does a rabbits heart beat than a dogs rabbits heart beat per 1 minute 212 dogs heart beat per 1 minute
Answer: In 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat
Step-by-step explanation:
Since we have given that
Rabbit's heart beat in 1 min 212 times more than dog's heart beat in 1 min.
So, in 1 hour , we get,
[tex]1\text{ hour }= 60\text{ minutes}\\so, heartbeat = 212\times 60=12720[/tex]
So, in 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat .
To determine how many more times a rabbit's heart beats than a dog's in an hour, multiply the rabbit's beats per minute by 60 to get the hourly beat total, and do the same for the dog. Subtract the dog's total from the rabbit's to find the difference. Assuming a dog's heart rate of 70 beats per minute, a rabbit's heart beats 8,520 more times per hour than a dog's.
To calculate how many more times a rabbit's heart beats than a dog's in one hour, we first need to establish the number of beats per hour for both animals. Since the rabbit's heart beat is 212 times per minute, we multiply this number by 60 (the number of minutes in an hour) to find out the total heartbeats in one hour for a rabbit:
Rabbit heartbeats per hour = 212 beats per minute x 60 minutes = 12720 beats per hour.
Next, we need the same figure for the dog. Without the specific heart rate for the dog, we'll assume a generic heart rate for calculation purposes. For example, if a dog's heart beats 70 times per minute (a common rate for dogs), we multiply by 60:
Dog heartbeats per hour = 70 beats per minute x 60 minutes = 4200 beats per hour.
Now, to find out how many more times the rabbit's heart beats than the dog's, we subtract the dog's heartbeats per hour from the rabbit's:
Rabbit's additional heartbeats = 12720 beats per hour - 4200 beats per hour = 8520 more beats per hour.
C is directly proportional to d such that c=1.5d.
find c when D=12: First you have to plug in the number so if d=12 the you do c=12(1.5) which equals 18. C=18
Find d if C=15: you now have to do the inverse operation. if c=d1.5 then d= c/1.5 Then plug in the numbers again, d=15/1.5 it equals 10, so d=10

At midnight, the temperature was 30 degrees F. By 6:00 a.m., it had dropped 5 degrees and by noon, it had increased by 11 degrees. What was the temperature at noon?
Answer: 36 degrees
Step-by-step explanation:
subtract 5 from 30=25
add 11 to 25
25+11=36
Considering the temperature changes throughout the day, the temperature at noon was 36 degrees F.
Explanation:If the temperature started at 30 degrees F at midnight, and it dropped 5 degrees by 6:00 a.m, the temperature at 6:00 a.m. was 30 - 5 = 25 degrees F. Then, if the temperature increased by 11 degrees F by noon, we just add this increase to the temperature at 6:00 a.m. This results in 25 + 11 = 36 degrees F. So, the temperature at noon was 36 degrees F.

[tex]\frac{7}{9} -\frac{2}{8} \times \frac{4}{9}[/tex]
Start by multiplying the fractions together. When multiplying fractions they don't need to have a common denominator, so multiply 2/8 and 4/9 from left to right.
[tex]\frac{2}{8} \times \frac{4}{9} = \frac{8}{72}[/tex]
Now your new problem looks like: 7/9 - 8/72. When subtracting fractions they have to have common denominators so multiply 7/9 by 8/8.

John Thunderhawk is making furniture. He finds that to design a particular cabinet and set up his shop to produce it costs $1,800. Then the labor and supplies to build each one are $400. So his cost, y, for x items is represented by y=1,800 + 400x. He can sell the cabinets for $600. So his revenue, y, is represented by y=600x. The solution to this system of equations is his break-even point, the point beyond which he starts making a profit. How many cabinets must he sell to break-even?
The number of cabinets he must sell to breakeven is 9.
How many cabinets must he sell?
Breakeven is when the total cost and the revenue is zero. At the breakeven point, profit is zero.
Breakeven : total cost = revenue
1800 + 400x = 600x
In order to determine the value of x, take the following steps:
Combine similar terms:
1800 = 600x - 400x
Add similar terms together
1800 = 200x
Divide both sides of the equation by 200
x = 1800 / 200
x = 9

To break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.
The break-even point occurs when the total cost is equal to the total revenue.
We can find this point by setting the cost equation and the revenue equation equal to each other and solving for x :
Set the cost and revenue equations equal :
Given that the cost equation is y = 1,800 + 400x, and the revenue equation is y = 600x , set these two equations equal to find the break-even point:
[tex]\[ 1,800 + 400x = 600x. \][/tex]
Rearrange the equation :
Subtract 400x from each side:
[tex]\[ 1,800 = 200x. \][/tex]
Solve for x :
Divide by 200 to isolate x :
[tex]\[ x = \frac{1,800}{200} = 9. \][/tex]
Therefore, to break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.

Here's the question: You have an electrical circuit with various components, all of which are in series. The current (I) through the system is (5.772 - 5.323i) milliamperes (mA). The impedance (Z) in that same system is (3.342 + 4.176i) kilohms (kΩ). Please tell me the magnitude of the voltage in the circuit.
Answer:
41.99 or 42.0 volts.
Step-by-step explanation:
We have been given the impedance (Z) of the circuit which is:
[tex]Z=3.342+4.176i[/tex]
and the current through the circuit is:
[tex](5.772-5.323i)[/tex]
The voltage across the circuit is given by:
[tex]V= I\times Z=IZ[/tex], where 'V' is the voltage, 'I' is the current, and 'Z' is the impedance.
Plugging the values of 'I' and 'Z' we get:
[tex]V=(5.772-5.323i)\times 10^{-3}\times (3.342+4.176i)\times 10^3[/tex]
[tex]V=(5.772-5.323i)\times(3.342+4.176i)[/tex]
[tex]V= (41.51+6.31i)[/tex]
Now that we have the voltage, we can find the magnitude of the voltage as follows:
[tex]V= \sqrt{(41.51)^2+(6.31)^2}=\sqrt{1723.08+39.81}=\sqrt{1762.89}=41.98 \approx 42.0[/tex]
So the magnitude of the voltage across the circuit is 42.0 Volts.
George had $235 in his checking account he withdrew $20 each day on Monday Tuesday and Wednesday George got paid on Friday and deposited $130 into his checking account then on Saturday he wrote two checks one for a $167 and one for $212 what was the checking balance after writing the checks
235$ and if you withdraw 20$ on three days thats 60$ so if we remove that from the account we have 175$ left.
Then on Friday when he got paid he put 130$ into the bank he has 175+130=305$
If he wrote a check 1 for 167$ and 1 for 212$ thats his account balance - 212 then -167 = 305 -378 so he has a balance of -73
The checking balance after writing the checks is -$74.
Explanation:To calculate the checking balance after writing the checks, we need to keep track of George's transactions:
Starting balance: $235Monday: Withdraw $20 (-$20)Tuesday: Withdraw $20 (-$40)Wednesday: Withdraw $20 (-$60)Friday: Deposit $130 (+$70)Saturday: Write a check for $167 (-$97)Saturday: Write a check for $212 (-$309)To find the final balance, we add the positive values (deposits) and subtract the negative values (withdrawals and checks):
Starting balance ($235) + Deposits ($130) - Withdrawals ($60) - Checks ($167 + $212) = $235 + $130 - $60 - $167 - $212 = -$74
Therefore, the checking balance after writing the checks is -$74.

Solution-
Quadratic regression equation,
[tex]y =ax^2+bx+c[/tex]
taking x = input/independent variable = year - 2000
and y = output/dependent variable = share of the global GDP
To plot a quadratic equation for the data points, we need to calculate all the constants a,b and c , then putting all the values in the general equation we can get the best fit curve for the data set.
Using, the graphing calculator, we can calculate the values of a, b, and c. The values were found to be,
a = -0.0471
b = 2.6366
c = 12.1001
Putting all the values,
[tex]y =-0.0471x^2+2.6366x+12.1001[/tex]
This is the best fit quadratic function that models the share of the global GDP.
For calculating the share of GDP in the year 2027, we can put the value of x to get the value of y.
x = year-2000=2027-2000=27,
[tex]y=-0.0471(27)^2+2.6366(27)+12.1001=-0.0471(729)+2.6366(27)+12.1001=48.95[/tex]
∴ In the year 2027, the maximum share will be 48.95% of total GDP.
The detailed answer explains how to find the quadratic function that models the data and calculates the predicted share of the GDP in 2027 using the quadratic function.
Quadratic Function Model:
Using the given data points, we can find the quadratic function that best models the developing economies' share of global GDP. This can be achieved by fitting a quadratic equation to the data.
The quadratic function that best models the data is: y(x) = 0.7386x^2 - 28.4235x + 276.0976
Predicted Share of GDP in 2027:
To find the predicted share of the GDP in 2027, substitute x = 27 (since 2027 is 27 years after 2000) into the quadratic function.
By calculating, the predicted share of the GDP in 2027 is approximately 44.5233%.

A veterinarian needs to know an animals weight in kilograms.If 20 pounds is about 9 kilograms and a dog weighs 30 pounds,use a ratio table to find the dogs weight in kilograms.
Answer:
13.5 kgs.
Step-by-step explanation:
Here we have to find conversion factor of lbs into kg.
For this we use the given information.
Given that the weight of a dog is 20 lbs and also 9 kg.
Hence we have conversion factor as
20 lbs = 9 kg
Or 1 lb =9/20 = 0.45 kg.
Using this, we find the 30 lb converted into kg.
For 1 lb, equivalent kg = 0.45
Hence for 30 lbs equivalent kg= 30(0.45) = 13.5 kg.
