Determine the circumference of a circle with a radius of 4 units.

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.

What is true about the way you should approach financial goals across different stages of your life? a. failure to meet a financial goal is a sign of personal weakness, so you should never alter a goal until you have completed it exactly as you imagined it. b. you need to be consistent and determined when it comes to financial goals. the financial goals you make as a young adult should stay in place for the rest of your life. c. most people tend to make more money as they grow older and more experienced. after a certain point in your life you should have enough money to meet all of your financial goals, at which point you will no longer need to concern yourself with long-term goals. d. as you progress through life, your values and financial possibilities will gradually change, which leads to an evolution of your financial goals over time
