You drove for half the time at 60mph and the other half the time at 30mph.
To find your average speed, we add 60 and 30 then divide them by two (because you drove at 2 different speeds). 60+30 = 90 and 90/2 = 45 so 45 miles per hour is your average speed.
Note: Velocity implies a direction to the force and there is no direction in this question, just speed. Without direction we cannot use velocity, only speed.
I could be wrong because I didn’t take business calculus, but i guess it’s the same as regular calculus.
So I assumed that the revenue is equal to the price times the amount produced: R=px
Now differentiating, I get: dR/dt =pdx/dt +xdp/dx. I used the product rule
But Mr. Kong wants his revenue constant ? So I assume that dR/dt=0
Plug in values and solve dx/dt. Please message me back. I want to see if I got it write

Answer: D) At the next school assembly, choose one student from each of 20 randomly selected rows.
Step-by-step explanation:
A wouldnt be correct because it is all students from the spots program
B isnt correct because it is 10 girls and 10 boys from the girls' and boys' soccer teams
C wouldnt be correct because it would be the first 20 students she sees once she leaves statistics class
D is the only unbiased, completely random selection choice.
(3,5)....x1 = 3 and y1 = 5
(1,3)....x2 = 1 and y2 = 3
slope formula : (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (1 - 3) = -2/-2 = 1 <== slope is 1
