Answer:
range: 13, mean: 6
Step-by-step explanation:
You get range by subtracting the largest number (15) by the smallest number (2). 15-2 equals 13.
You get mean by adding up all of the numbers (2+2+3+4+5+5+6+8+10+15=60) and dividing the sum by the amount of numbers in the list (10). 60/10 equals 6.
Answer: No.
Step-by-step explanation:
Given: A treasure chest sinks at a rate no less than 20 feet per second.
Speed = -20 feet per second.
The depth of ocean = -4200 feet
Since 1 minute = 60 seconds
Therefore 3 minutes=
180 seconds
The depth D reached by treasure chest in 3 minutes is given by :-
![D=Speed\times time\\\Rightarrow\ D=-20\times180\\\Rightarrow\ D=-3600\ feet](https://tex.z-dn.net/?f=D%3DSpeed%5Ctimes%20time%5C%5C%5CRightarrow%5C%20D%3D-20%5Ctimes180%5C%5C%5CRightarrow%5C%20D%3D-3600%5C%20feet)
Clearly -4200<-3600
Therefore, the treasure chest can not reach the ocean floor in less than 3 minutes.
Answer:
The numbers are 8 and 6
Step-by-step explanation:
Let x and y be the two numbers
x+y = 14
x-y = 2
Add the two equations together
x+y = 14
x-y = 2
--------------
2x +0y = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 14
8+y =14
Subtract 8 from each side
8+y-8 =14-8
y =6
The numbers are 8 and 6
