Cómo se calcula la probabilidad de que salga el número 5 lanzando un dado 20 veces​

Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?

Formulate alisha has a number in mind. if she adds three to her number the result is less than five. use this information to write and solve an inequality about alisha's number. then graph the solution set.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
