D1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, in ascending order
Q2 (median) = d5 = 2 //value in the middle
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 is middle value of d1,d2,d3,d4, but there is no middle element among four elements, that is why arithmetic mean is taken)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquantlie range = IQR = Q3 - Q1 = 5 -1 = 4
answer: 4
Some of the rates that can be formed are; Speed = 8.333 mph
Number of miles covered per gallon of gasoline used = 14.706 mpg
The number of gallons used per hour = 0.567 gallons per hour
<h3>How to use units conversion?</h3>
We are told that the Northwest Football team drove 25 miles.
Now, the time that this team took was 3 hours.
Thus, one rate that can be formed is the speed in mi/hr. Thus;
Speed = 25/3 = 8.333 mph
Another rate that can be found is the number of miles covered per gallon of gasoline used. This gives us;
25/1.7 = 14.706 mpg
Another rate that can be gotten is the number of gallons used per hour;
= 1.7/3 = 0.567 gallons per hour

Answer:
x= 
MARK ME BRAINLIEST PLEASE
Answer:
The numbers are 87 and 106
Step-by-step explanation:
x + y = 193
x - y = 19
Add y to both sides of the equation
x = 19 + y
Substitute new value for x into first equation
19 + y + y = 193
Add y's together
19 + 2y = 193
Subtract 19 from both sides of the equation
2y = 174
Divide both sides of the equation by 2
y = 87
193 - 87 = 106
The numbers are 87 and 106
Hope this helps :)
