👉🏼ξ = { 2, 3, 4, 5, 7, 9 },. A = { 2, 3, 4, 5, 7}, B = {2, 3, 5, 9 }. A number, x, is picked at random from ξ. Find P(x 𝜀 A∩B’)

👈🏼w is inversely proportional to y. x is directly proportional to the cube root of y. When y = 6.5 w = 8 and when w = 27, x = 100. Find the value of x when y = 0.8125

👆🏼3x = 4y and . Find x : y : z

👇🏼Make y the subject of

🖐🏼 c = 9.5 rounded to 1 decimal place and x = 4.81 rounded to 2 decimal places. Calculate the lower bound of w.
