Answer:
They would be normally distributed.
Step-by-step explanation:
Because there are more than 30 samples, the distribution would closely resemble the normal distribution.
40 ticketholders are winning the contest. 40 ≥ 30. This is enough to make the distribution approximately normal.
Answer:
0.28
Step-by-step explanation:
The volume of a cylinder is given by the multiplication of the area of the base by the height of the cylinder. π×r²(area of the base) × h (height of the cylinder) ⇔

×

cm²×35cm=12127.5cm³
(r is half of the diameter. Because we are doing the square of r, the cm also are squared.)
Rounding to the nearest tenth is to round the result so that it maintains a number after the point - the result is 12127.5cm³
