Answer:
22.5 batches
Step-by-step explanation:
We can solve this problem by dividing 9/12 by 2/12. We should do this because to find how many sets of something are in a number, the question is asking us to do division. Doing this, we get 9/12 * 12/2, giving us our answer of 4.5 sets of 2/12 in 9/12.
Answer:
ok this is that and that is this.hope this helps
Answer:
(4,10)
Step-by-step explanation:
7-3= 4
5=5=10
STEP 1
Mean =
![\frac{300+785+670+187+760+724}{6} = \frac{3426}{6}=571](https://tex.z-dn.net/?f=%20%5Cfrac%7B300%2B785%2B670%2B187%2B760%2B724%7D%7B6%7D%20%3D%20%5Cfrac%7B3426%7D%7B6%7D%3D571%20)
STEP 2
Subtract the mean from each data value then square the answer
![300-571=-271](https://tex.z-dn.net/?f=300-571%3D-271)
⇒
![(-271)^{2} =73441](https://tex.z-dn.net/?f=%20%28-271%29%5E%7B2%7D%20%3D73441)
![785-571=214](https://tex.z-dn.net/?f=785-571%3D214)
⇒
![(214)^{2}=45796](https://tex.z-dn.net/?f=%20%28214%29%5E%7B2%7D%3D45796%20)
![670-571=99](https://tex.z-dn.net/?f=670-571%3D99)
⇒
![(99)^{2}=9801](https://tex.z-dn.net/?f=%20%2899%29%5E%7B2%7D%3D9801%20)
![187-571=-384](https://tex.z-dn.net/?f=187-571%3D-384)
⇒
![(-384)^{2} =147456](https://tex.z-dn.net/?f=%20%28-384%29%5E%7B2%7D%20%3D147456)
![760-571=189](https://tex.z-dn.net/?f=760-571%3D189)
⇒
![189^{2}=35721](https://tex.z-dn.net/?f=189%5E%7B2%7D%3D35721%20)
![724-571=153](https://tex.z-dn.net/?f=724-571%3D153)
⇒
![153^{2} =23409](https://tex.z-dn.net/?f=153%5E%7B2%7D%20%3D23409)
STEP 3
Add the squared answers in STEP 2 then find the mean
![\frac{73441+45796+9801+147456+35721+23409}{6}= \frac{335624}{6}=55937.3](https://tex.z-dn.net/?f=%20%5Cfrac%7B73441%2B45796%2B9801%2B147456%2B35721%2B23409%7D%7B6%7D%3D%20%5Cfrac%7B335624%7D%7B6%7D%3D55937.3%20)
STEP 4
Square root the answer in STEP 3
![\sqrt{55937.3} =236.5](https://tex.z-dn.net/?f=%20%5Csqrt%7B55937.3%7D%20%3D236.5)
Standard deviation is 236.5
