Answer:
0.16
Step-by-step explanation:
The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:
Here the standard deviation is
![= \sqrt{npq} \\\\= \sqrt{20\times 0.18 \times (1 - 0.18)}\\\\= \sqrt{20\times 0.18\times 0.82}\\\\= \sqrt{2.952}](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7Bnpq%7D%20%5C%5C%5C%5C%3D%20%5Csqrt%7B20%5Ctimes%200.18%20%5Ctimes%20%281%20-%200.18%29%7D%5C%5C%5C%5C%3D%20%5Csqrt%7B20%5Ctimes%200.18%5Ctimes%200.82%7D%5C%5C%5C%5C%3D%20%5Csqrt%7B2.952%7D)
= 1.72
Now the minimum no of smokers is
![= np - 2\times 1.72\\= 20 \times 0.18 - 3.44\\\\= 0.16](https://tex.z-dn.net/?f=%3D%20np%20-%202%5Ctimes%201.72%5C%5C%3D%2020%20%5Ctimes%200.18%20-%203.44%5C%5C%5C%5C%3D%200.16)
Answer:
360 cm cubed
Step-by-step explanation:
Use the volume formula.
V=whl
V=12 x 6 x 5
V=360
The answer is 5x-11
You have to distrivute 1/3 into 6x and -9 and after you have your answer for those you can combine like terms.
74 units would be your answer for the length segment
