Answer:

<u> -54.5%</u>

Step-by-step explanation:

You will have to use this formula

\frac{new value-oldvalue}{oldvalue}

When substituted in you have \frac{30-66}{66}

30-66=-36

-36/66= -0.54 (54 repeating)

Then you have to convert this into a percentage, -54.54(repeating) percent

To the nearest hundredth you would round down to<u> -54.5%</u>.

It is a Decrease because it is negatated.

in a roulette wheel there are 38 numbered slots: 36 slots are the numbers 1 through 36 and the remaining two slots are 0 and 00.
frez [133]

roulette consists in placing a small ball in a roulette wheel, Probability (Roulette ball not landing on red) = 10 / 19

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes

Given:

Number of total slots = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

Find:

Probability (Roulette ball not landing on red)

Computation:

Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)

Probability (Roulette ball not landing on red) = 1 - (18 / 38)

Probability (Roulette ball not landing on red) = 20 / 38

Probability (Roulette ball not landing on red) = 10 / 19

Answer:

\frac{16 {d}^{3} }{ {c}^{2} }

Step-by-step explanation:

{4}^{2}  {c}^{ - 2}  {d}^{3}  {e}^{0}

➡️ 16 {c}^{ - 2}  {d}^{3}  \times 1

➡️ 16 {c}^{ - 2}  {d}^{3}

➡️ 16 \times  \frac{1}{ {c}^{2} }  \times  {d}^{3}

➡️ \frac{16 {d}^{3} }{ {c}^{2} }
