Answer:
Smallest number is 18. Largest number is 30.
Step-by-step explanation:
a:b:c = 4:5:3
∃x such that a = 4x, b = 5x, c = 3x
"sum of the numbers is 72"
a+b+c = 4x+5x+3x = 72
x = 6
a = 4x = 24
b = 5x = 30
c = 3x = 18
Answer:
It will affect the process in the sense that the sample population size will be unknown due to the fact that we don't know the population standard deviation.
Step-by-step explanation:
We are told that you do not know the population standard deviation. Thus, the sample population will not be able to be calculated because this sample standard deviation given will not suffice and we need the population standard deviation to be able to calculate the sample population size.

Answer:
The resultant vector is
. The resultant displacement is 1 miles.
Step-by-step explanation:
It is given that Minossoo is training for cross country in the fall. He ran 5 miles east. Then he turned around and ran 4 miles west.
Let he start from point A, then ran 5 miles east and reach to point B. After that he turned around and ran 4 miles west to reach point C.
![|\overrightarrow{AB}|=5miles](https://tex.z-dn.net/?f=%7C%5Coverrightarrow%7BAB%7D%7C%3D5miles)
![|\overrightarrow{BC}|=4miles](https://tex.z-dn.net/?f=%7C%5Coverrightarrow%7BBC%7D%7C%3D4miles)
His initial direction is east, then he turned and run along the west direction. The resultant vector is
![\vec{v}=\overrightarrow{AB}-\overrightarrow{BC}](https://tex.z-dn.net/?f=%5Cvec%7Bv%7D%3D%5Coverrightarrow%7BAB%7D-%5Coverrightarrow%7BBC%7D)
The resultant displacement
![\vec{v}=5-4=1](https://tex.z-dn.net/?f=%5Cvec%7Bv%7D%3D5-4%3D1)
Therefore resultant vector is
. The resultant displacement is 1 miles.
