If a 200-mile trip takes 4 hours to com- plete, the average speed is A. 30 miles per hour.

B. 40 miles per hour.

C. 50 miles per hour.

D. 60 miles per hour.

Step-by-step explanation:

if you need 4 h to complete a trip of 200 miles

200/4=50 miles/hour

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
