Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)
The second moment is..
In order to solve it you insert the point in slope from
the equation is
Y=Mx+b
Plug it in as
-4=3(8)+b
-4=24+b
Then subtract 24
B=-28
So
The answer is
Y=3x-28
Answer:
$56,320 is the year 2 profit
Step-by-step explanation:
$ 32,000 x .76 = $24,320
$32,000 + $24,320 = $56,320
Table: The number 60 goes underneath 5.
The number 7 goes above 84.
120 under 10.
12 above 144.
Explanation: Refer to the next question. Each ratio will equal out to 1/12 so you either divide or multiply 12 for each one.
5x12=60
84/12=7
10x12=120
144/12=12
1. 1/12
Explanation:
2 packets of flavoring to 24 ounces of water, 24/2 is 12.
4. 276 ounces of water
Explanation:
12 ounces of water to every packet of flavoring so we need to multiply 23 by 12 which equals 276.
5. Yes. (9.5, 114) makes sense because it follows the ratio of 1:12. 114/9.5=12; 9.5x12=114.
6. 36/3, 66/5, 108/9, 180/15
Explanation:
24/2 = 12, multiply each bottom number by 12 and divide each top number by 12.
7. It uses multiplication because you are multiplying by 12.
