The answer is choice A) 2
The main cluster of data is the group {12, 12, 14, 17, 18, 19} as they aren't very far apart in distance (plot the values on a number line). The range of this group is 7 since 19-12 = 7. Compare this to the distance from 2 to 12 which is 10 units; a far greater distance than 7. So the value 2 is on its own on an "island" so to speak
Answer:
x = 1/10
Step-by-step explanation:
2/x -2 = 3/2x +3
Add 2 to each side
2/x -2+2 = 3/2x +3+2
2/x = 3 /2x +5
Subtract 3/2x from each side
2/x -3/2x = 3 /2x - 3/2x +5
2/x - 3/2x = 5
Get a common denominator
2/x *2/2 -3/2x =5
4/2x - 3/2x = 5
1/2x =5
Multiply each side by 2x
1 /2x * 2x = 5 *2x
1 = 10x
Divide each side by 10
1/10 = 10x/10
1/10 =x
Answer:
310 feet per mile marker
Step-by-step explanation:
The average change will be the difference in elevation over the difference in mile markers. Randy’s elevation changed from 6220 feet to 8390 feet, which is a difference of
8390-6220=2170 feet. He started tracking at mile markers 6 to mile markers 13, which is a difference of
13-6=7 miles markers. The average change in elevation is 2170 feet / 7 mile markers = 310 feet per mile marker.
