Answer:
In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean.
To calculate the standard deviation of those numbers:
Work out the Mean (the simple average of the numbers)
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.
Take the square root of that and we are done!
Option D
Money earned by Marty is $ 16.72
<em><u>Solution:</u></em>
Given that, Marty started a lawn mowing business
He kept track of his expenses and earnings in a table
Lawn Mower = - $49.99
Gasoline = - $8.79
Moyer's yard = $ 40
Griffen's yard = $ 35.50
To find: Money earned by Marty
Total money earned = lawn mower + gasoline + moyers yard + griffens yard
Total money earned = -49.99 - 8.79 + 40 + 35.50
Total money earned = -58.78 + 40 + 35.50
Total money earned = -18.78 + 35.50 = 16.72
Thus money earned by Marty is $ 16.72
Hello!
Since y is equal to both of them they are equal to each other
3x + 7 = 3x + 2
Now you solve it algebraically
Subtract 2 from both sides
3x + 5 = 3x
Subtract 3x from both sides
5 = 0
Since 5 does not equal 0 there are no solutions
The answer is D
Hope this helps!
