URGENT PLEASE ANSWER FAST, WILL MARK BRAINLIEST Sammy has 30 plastic frogs in a box.
The box contains an equal amount of green, red, and
purple plastic frogs. There are no other colors. A frog is
randomly selected from the box, and then replaced in the
box and a frog is again selected.
Find the probability that
1. A green frog will be selected both times
2. A red or purple frog jwill be selected the first draw
3. A green frog is selected only the first draw

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?
