Answer:
Step-by-step explanation:
e) 3√2 (-3√6 -2 -6)
3√2 (-3√6 - 8)
-9√12 - 24√2
-9√(2^2 * 3) - 24√2
-18√3 - 24√2
or
6(-3√3 - 4√2)
f) -5√2 (3 + 2√2 - 6 - 1)
-5√2(-4 + 2√2)
20√2 - 20
or
20(√2 - 1)
To calculate the standard deviation of those numbers:<span>
1
Work out the Mean (the simple average of the numbers)
2
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.<span>Take the square root of that and we are done!</span></span>
-530
I hope this helps! (^_^)
Answer:
50s + 2000 =
Step-by-step explanation:
50s + 2000 = Marie's salary
she gets an additional $50 per sale she makes on top of her 2,000 per month. so let's say that she made 10 sales that month you would just plug 1o in for s. it would look like:
50(10) + 2000 = 2500
Well since there are 60 minutes in an hour with means there has 120 minutes
Divide 60 by 5 = 12 x 3 = 36
120 + 36 = 156 minutes.
