The Standard Deviation is a measure of how spread out numbers are. Standard deviation can be calculated by the expression as follows:
s = √∑(x - x(mean))^2/n-1
x(mean) = 24
s = √∑(x - 24)^2 / 7-1
<span>s = 6.11
Hope this answers the question. Have a nice day.</span>
Answer: The required ratio would be 
Step-by-step explanation:
Since we have given that
∠O=90°,
MO = 15, (Perpendicular)
ON = 8, (Base) and
NM = 17 (Hypotenuse)
So, we need to find the cosine of ∠N.
As we know that

Hence, the required ratio would be 
Answer: 426.5
Step-by-step explanation:
You know that she spent 34.12 on gas and you also know that that amount of money was the 8% of her paycheck.
Therefore, keeping the above on mind, you can write the following expression, where
is the total amount of money of her paycheck:

When you solve for
, you obtain the result shown below:

A) let the number of cameras sold per day for breakeven be x
Total daily cost = 2000 + 9x
Total daily revenue = 17x
therefore for just covering expenses both cost and revenue must be equal
2000 + 9x = 17x
2000 = 17x - 9x = 8x
x = 2000/8 = 250 cameras
b) increasing production by 50 cameras per day will give a daily profit of;
50 * (17 - 9) = 50 * 8 = $400 (seeing that the fixed daily cost of $2000 remains unchanged)
It's a
