PLEASE HELP! WILL GIVE BRAINLIEST! Jackson loves an adventure but always wants to know what he is getting himself into before he jumps in completely. He decides to take a rock climbing course. He arrives at the course which is meeting at the base of the mountain. He looks up and decides he needs to know how far UP he will be climbing. The instructor doesn’t know the height of this location (Jackson is starting to doubt the instructor’s ability if he doesn't know this simple fact) Jackson needs to figure out a way to know the approximate height before climbing. Jackson decides to use his highschool geometry skills to determine the height. He needs a mirror and luckily another climber pulls one out of his backpack. Jackson places the mirror on the ground so that he is able to look at the mirror and see the top of the mountain.
The mirror is 5 feet in front of him and is approximately 40 feet from the base of the mountain. ∆ Jackson is 6’4” tall. Approximately how high is the top of the mountain. -

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

The upcoming championship high school football game is a big deal in your little town. the problem is, it is being played in the next biggest town, which is two hours away! to get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. you determine that if more than three students share a ride, on average, you will create the app. you conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. the following data are collected: 6 5 5 5 3 2 3 6 2 2 5 4 3 3 4 2 5 3 4 5 construct a 95% confidence interval for the mean number of students who share a ride to school, and interpret the results. part a: state the parameter and check the conditions. part b: construct the confidence interval. be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process. part c: interpret the meaning of the confidence interval. part d: use your findings to explain whether you should develop the ride-share app for the football game.
