Change 150% into a decimal by multiplying it by 100.
150(100)= 1.50
Now multiply 1.50(66)= 99

66 is the 100%
we can solve this problem by the rule of three.

Therefore:
66------------------------100%
x--------------------------150%

x=(66 * 150%) / 100%=99

Answer 150% of 66 is 99.

Other method:
150% of 66=1.5 *66=99

Answer: 150% of 66 is 99.

Answer:

The expectation is -$0.2632

Step-by-step explanation:

Consider the provided information.

The total number of balls are: 18 red + 18 black + 2 green = 38

If the ball lands on a red number, the player wins the amount of his bet.

The bat is ball will land on a red number.

The favorable outcomes are 18/38 and unfavorable are 20/38.

Let S be possible numerical outcomes of an experiment and P(S) be the probability.

The expectation can be calculated as:

E(x) = sum of S × P(S)

For $S_1 = 5$

$P(S_1) = \frac{18}{38}$

For $S_2 = -5$ (negative sign represents the loss)

$P(S_2) = \frac{20}{38}$

Now, use the above formula.

$E(x) = 5\times \frac{18}{38}-5\times \frac{20}{38}$

$E(x) = \frac{90}{38}-\frac{100}{38}$

$E(x) = \frac{-10}{38}$

$E(x) = -0.2632$

Hence, the expectation is -$0.2632

What is the minimum angle of rotation (in degrees) that will carry the star onto itself?

zloy xaker [14]

Answer:

When you rotate the regular pentagon \begin{align*}72^\circ\end{align*} about its center, it will look exactly the same. This is because the regular pentagon has rotation symmetry, and \begin{align*}72^\circ\end{align*} is the minimum number of degrees you can rotate the pentagon in order to carry it onto itself.
