Step-by-step explanation:
the first one
1/3 is 5/15 so you can fill 5/15 +5/15 (2bags) and you will have 2/15 pounds left
Answer:
386
Step-by-step explanation:
4+4+5x2x5+(3+3+3)x6x6+2+2
=4+4+5x2x5+9x6x6+2+2
=4+4+50+324+2+2
=386
If it was one year it would be 2200 and you just keep adding 200 for each year.
Answer:
D. 14.32
Step-by-step explanation:
The formula for standard deviation is:
![SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}](https://tex.z-dn.net/?f=SD%20%3D%20%5Csqrt%7B%5Cfrac%7B%5Csum%20%7C%20x-%5Cmu%7C%5E2%7D%7BN%7D%7D)
The mean μ is 33.
The (x minus μ) squared are 361, 49, 49, 361 respectively.
So that the SD = ![\sqrt{\frac{820}{4}} \approx 14.31782...](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B820%7D%7B4%7D%7D%20%5Capprox%2014.31782...)
