Doug is going to ride his bicycle 3,000 miles across the united states, from coast-to-coast. he wants to choose the route that will give him the greatest chance of success. here's what he finds in his research:

-there have been 2 attempts on the northern route from maine to washington. both of those riders made it 2,000 miles and quit in montana.

-there have been 19 attempts on the central route from virginia to california; 9 of those riders didn't make it out of virginia and the other 10 made it all the way to the pacific.

-there have been 32 attempts on the southern route from florida to san diego. one of those riders made it the whole way. another one went half a mile, realized he was out of shape, and quit. the other 30 riders quit somewhere in texas. they were evenly distributed between 1,300 and 1,700 miles.

which of the following is true? choose all answers that apply.

-the southern route has the lowest median distance traveled among the three routes.

-the standard deviation for distance traveled on the northern route is very low.

-the interquartile range for distance traveled on the southern route is less than 500 miles.

-the standard deviation for distance traveled on the southern route is less than the standard deviation for distance traveled on the central route.

Do you mind if you guys me with this question i’m on number 8

1.3.4 practice : modeling: solving linear equations in this assignment, you may work alone, with a partner, or in a small group. discuss the results of your work and/or any lingering questions with your teacher. your assignment: road trip you're taking a scenic road trip down ca-highway 1 from san jose, california, to los angeles. you plan to split the drive into two days, stopping for one night. choose one town to stop in, and find the driving distance for the second day. 1. circle the town you chose to stop in. (1 point) santa barbara: an image of palm trees san luis obispo: an image of a church 2. why did you choose this town? (1 point) 3.what do you know? .what do you want to find out? .what kind of answer do you expect? define the variable. 4. what is the variable x for this problem? (1 point) write the equation. 5. write an equation showing that the distance traveled on the first day plus the distance traveled on the second day is equal to 425 miles. (4 points: 2 points for each side of the equation) isolate the variable. 6. what inverse operation do you need to perform on both sides to isolate x in the equation? (2 points: 1 point for the correct number, 1 point for the correct operation) solve the equation. 7. solve the equation for x. interpret the answer in terms of the problem. (2 points: 1 point for the solution, 1 point for the interpretation) check your solution. 8. to confirm that your answer is correct, add the two days' distances. this should equal the total distance from san jose to los angeles. show your work as an equation. (3 points: 1 point for the setup, 2 points for the correct answer)
