Anytime you subtract a negative number, it changes it to adding a positive number.
-2 + 0.7
Since we are adding, we will have an arrow going to the right
-2 + 0.7 = -1.3
Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3
Best of Luck!
Lets put the numbers in order...
6,7,7,8,8,9,9,10,11,30
Q1 = 7
Q2 = (8 + 9) / 2 = 17/2 = 8.5
Q3 = 10
IQR = Q3 - Q1 = 10 - 7 = 3 <== so the interquartile range is 3
mean absolute deviation...
the mean of our data is 10.5
now we subtract the mean from every data point....and find its absolute value
6 - 10.5 = -4.5.....| -4.5| = 4.5
7 - 10.5 = -3.5.....| -3.5| = 3.5
7 - 10.5 = -3.5.....|-3.5| = 3.5
8 - 10.5 = - 2.5....|-2.5| = 2.5
8 - 10.5 = -2.5....|-2.5| = 2.5
9 - 10.5 = -1.5....|-1.5| = 1.5
9 - 10.5 = -1.5....|-1.5| = 1.5
10 - 10.5 = -0.5..| -0.5| = 0.5
11 - 10.5 = 0.5...|0.5| = 0.5
30 - 10.5 = 19.5..|19.5| = 19.5
now we take the average of these numbers
(4.5+3.5+3.5+2.5+2.5+1.5 + 1.5 + 0.5+0.5+19.5) / 10 =
40/10 = 4 <== ur mean absolute deviation
In summary :
ur interquartie range (IQR) of ur data set is 3
ur mean absolute deviation (MAD) of ur data set is 4
Answer:
D 85/95
Step-by-step explanation:
17/19
Multiply the top and bottom by 3
17/19 *3/3 =51/57
Multiply the top and bottom by5
17/19 *5/5 =85/95
0.25m + 1.75= 15
Move +1.75 to the right side of the equal sign which becomes -1.75
0.25m=15-1.75
subtract 15 and 1.75 which is 13.25
0.25m=13.25
divide 0.25 by both sides. 0.25m divided by 0.25 is 1m and 13.25 divided by 0.25 is 53.
He can travel 53 miles
0.25m + 1.75= 15
