Step-by-step explanation:
Flipping a coin and rolling a number cube are both independent events. Independent events do not rely on the outcome of any previous events. This means that whatever you flip on the coin will have no effect on whatever you roll on the number cube and each flip of the coin or roll of the cube has the same probability as the flip or roll before.
The probability of getting tails on a coin toss is:
The probability of getting a number less than 3 (so 1 or 2) on a number cube is:
Since we are combining these events, we need to multiply the fractions together to get our overall probability:
*
=
The sum of ( x +
) + (
x -
) is
x +
Step-by-step explanation:
To add or subtract 2 fractions, they must have same denominators, if they not do that
- Find the Lowest common multiple of the two denominators (LCM)
- Replace each denominator by it
- Divide The LCM by each denominator and multiply the numerator of each fraction by its quotient
∵ ( x +
) + (
x -
)
- Let us start with adding the like terms
∴ ( x +
) + (
x -
) = (
∵ ( x +
x ) have same denominators, then we can add them
∴ ( x +
x ) =
x
∵ ( -
) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( -
) = (
-
) =
∴ ( x +
) + (
x -
) =
x +
The sum of ( x +
) + (
x -
) is
x +

Basically, you just have to use the formula of the volume of a cylinder, which is πr^2h, to find the answers
Sorry about the picture being blurry, really bad camera
3. Radius = 6 ÷ 2
= 3 cm
Volume = πr^2h
= π × 3^2 × 5
= 45π
