The probability of winning a game is 3/5. A player expects 30 wins. How many games did they play?

On a histogram the bar for 20 < x ≤ 30 has a frequency density of 3.5. How many values are in that class?On a histogram the bar for 20 < x <= 30 has a frequency density of 3.5. How many values are in that class?

A block has mass 610 g (to the nearest 10 g) and volume 19 cm³ (to the nearest cm³). Work out the upper bound of its density, to 2 decimal places.A block has mass 610 g (to the nearest 10 g) and volume 19 cm^3 (to the nearest cm^3). Work out the upper bound of its density, to 2 decimal places.

The point (-2, 5) lies on y = f(x). Write down its image on y = f(x) + 3.

y is directly proportional to x³. When x = 2, y = 32. Work out y when x = 4.y is directly proportional to x^3. When x = 2, y = 32. Work out y when x = 4.
