Please help me asap ​
Luden [163]

Answer:

16.28 ft^2

Step-by-step explanation:

To find the area of the square do Base Times height.

Base (5), Height (2)

5 * 2 = 10

To find the semi circle do the regular formula for a circle but divide it by 2 at the end.

Area of a circle is pi time r squared

3.14 * 2^2 = 12.56 (Remember always follow order of operations or PEMDAS by squaring 2^2 first)

Since its a semi circle divide the area of the circle by 2.

12.56 / 2 = 6.28

To find the area of them both you add both areas together.

6.28 + 10 = 16.28 Ft^2

A roulette wheel has 38 slots total, 36 of which are numbered 1 through 36, and 2 green slots labeled "0" and "00." For any spin
Morgarella [4.7K]

Answer:

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

Step-by-step explanation:

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
