Answer:
ok
Step-by-step explanation:
not really hard if you concentrate
right now check the curve and see if you'll see x axis
Given:
Let x be the whole amount inherited.
1/2 * x - invested with Bernie Madoff
1/3 * x - lost due to identity theft
1/8 * x - lost in casino
40,000 - remainder
x - x/2 - x/3 - x/8 = 40,000
LCM:
2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24
3: 3, 6, 9, 12, 15, 18, 21, 24
8: 8, 16, 24,
x * 24/24 = 24x / 24
x/2 * 12/12 = 12x / 24
x/3 * 8/8 = 8x / 24
x/8 * 3/3 = 3x / 24
40,000 * 24/24 = 960,000 / 24
24x/24 - 12x/24 - 8x/24 - 3x/24 = 960,000/24
(24x - 12x - 8x - 3x)/24 = 960,000/24
x/24 = 960,000/24
24 * x/24 = 24 * 960,000/24
x = 960,000
x = 960,000 initial inheritance
x/2 = 960,000/2 = 480,000 invested with Bernie Madoff
x/3 = 960,000/3 = 320,000 lost due to identity theft
x/8 = 960,000/8 = 120,000 lost in the casino
40,000 - remaining amount.
960k - 480k - 320k - 120k = 40k
40k = 40k
Answer:The reason there is no commutative property for subtraction or division is because order matters when performing these operations.
Step-by-step explanation:
Answer:
Because this spread will add up to zero
Step-by-step explanation:
Mean defines the center of the data. Some values are below this center and some values are above this center.
For the values which are below the center (i.e. less than the mean), when mean is subtracted from these values, this results in negative numbers.
For the values which are above the center(i.e. greater than the mean), when mean is subtracted from these values, this results in positive numbers.
When these negative and positive numbers are summed together, as it is, they cancel out each other, leaving an answer equal to zero, which would be meaningless. As a spread of 0 would mean all data values are the same, when infact they aren't.
To avoid this, the difference of mean from the data value is squared, so that we can get all positive values, and then these values are added up together to calculate the spread of the data.
Conclusion:
The average of deviations of individual data from the mean will result in answer equal to zero, as a result they are squared first before finding the average.
