Answer:
-4 and 6
Step-by-step explanation:
Q1 is the median (the middle) of the lower half of the data, and Q3 is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21). Q1 = 7 and Q3 = 16. Step 5: Subtract Q1 from Q3.
With reduction of order, we assume a solution of the form

, with

. Then


and substituting into the ODE gives



Let

, so that

. This gives the linear ODE

This equation is also separable, so you can write

Integrating both sides with respect to

gives


Next, solve

for

by integrating both sides again with respect to

.



And finally, solve for

.

and note that

is already taken into account as part of

, so this is the general solution to the ODE.
Answer:
B
Step-by-step explanation:
The range is the interval of y values.
Smallest y values is -9 and the highest y values is 9.
So the range is
Answer:
0.18 miles per minute.
Step-by-step explanation:
You need to divide 9/10 miles by 5 because 5 minutes/5=1 minute.
9/10/5=0.18 (or 18/100)
