First, we need to put the numbers in order...
58,60,69,71,78,78,85,85,86,87,88,91,93,95,95,95,96,98,100,100
and since there is an even number of numbers (20), we need to find the 2 middle numbers and divide them by 2 to find the median (Q2)
Q2 (the median) = (87 + 88) / 2 = 175/2 = 87.5
now we take all the numbers below 87.5...and find the median (middle number) and that number will be Q1...there is 2 middle numbers...so we add them and divide by 2
Q1 = (78 + 78) / 2 = 156/2 = 78
now we take all the numbers after 87.5....and find the median...there will be 2 numbers, so we add them and divide by 2..that wil be Q3
Q3 = (95 + 95) / 2 = 190/2 = 95
So in summary :
Q1 = 78 <==
Q2 = 87.5
Q3 = 95 <==
The interquartile range (IQR) is found by subtracting Q1 from Q3.
IQR = 95 - 78 = 17 <==

1/2X+4=X-4
1/2X+8=X
8=1/2X
16=X
(Pick one of the equations )
y=1/2X+4
y=(1/2)(16)+4
y=12
point: (16,12)
Answer:
150 miles
Step-by-step explanation:
Abdul's average speed in heavy traffic = 30 mph
Time Spent in heavy traffic = 1 hour
Distance covered in heavy traffic =Speed in heavy traffic X Time Spent in Heavy Traffic
=30 X 1 =30 miles
Abdul's Average speed in light traffic= 60 mph
Time Spent in light traffic = 2 hours
Distance covered in light traffic =Speed in light traffic X Time Spent in light Traffic = 60 X 2 =120 miles
Total Distance covered by Abdul = Distance covered in heavy traffic + Distance covered in light traffic
=30 + 120
=150 miles
