I can't seem to figure this out, thank you guys! If you can show your work so I can learn that would be great (all three questions go together).1. You and your best friend want to take a vacation to Peru. You have done some research and discovered that it will cost $2400 for the plane tickets, all-inclusive hotel and resort, and souvenirs. You have already saved $1750. If you invest this money in a savings account with a 2.3% interest rate compounded annually, how long will it take to earn enough money to go on the trip? Use the compound interest formula A = P (1 + i)n, where A is the accumulated amount, P is the principal, i is the interest rate per year, and n is the number of years. Round your final answer to the nearest tenth2. You are planning to go on this trip in 2 years. How much money will you need to invest at a 2.3% interest rate compounded annually in order to have $2400 in 2 years? Use the compound interest formula A = P (1 + i)n. (Round final answer to the nearest cent, but otherwise don’t round any intermediate values)3. Now say you only have $1600 to invest and the highest interest rate you can find is 3.55% compounded annually. If you decide to wait 7 years to go on the trip, how much money will you have to spend on the trip? Use the compound interest formula A = P (1 + i)n. (Round final answer to the nearest cent, but otherwise don’t round any intermediate values)

HELP PLEASE AND FAST I WILL FAIL The dot plot shows how many attempts it took for each student to complete a puzzle: Dot plot titled Puzzle Attempts and labeled Number of Attempts shows number line from 1 to 10. There are no dots over 1 and 10, 1 dot over 2 and 9, 2 dots over 3 and 8, 3 dots over 4 and 7, 5 dots over 5 and 6. Is the median or the mean a better measure of center for these data and why? Mean, because the data are skewed and there are outliers Mean, because the data are symmetric and there are no outliers Median, because the data are skewed and there are outliers Median, because the data are symmetric and there are no outliers
