Answer:

For each game, the player should be expected to lose $0.0263.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of each outcome:

1/38 probability of winning, that is, 1/38 probability of receiving $36.

37/38 probability of losing, that is, 37/38 probability of losing $1.

On average, how much money should a player expect to win or lose if they play this game repeatedly?

For each game:

[tex]E(X) = \frac{1}{38}*36 - \frac{37}{38}*1 = \frac{36 - 37}{38} = -\frac{1}{38} = -0.0263[/tex]

For each game, the player should be expected to lose $0.0263.

Answer:

10 hours or diez horas

Step-by-step explanation:

El total de horas entre las 7 am y las 5 pm es de 10 horas (5+5).

(English)

A clock, often known as a timepiece, is a device that measures and displays the passage of time.

The clock works in 12 hours time period, therefore, the time between 7 am and 12 pm is 5 hours, similarly, the time between 12 pm and 5 pm is 5 hours.

Thus, the total hours between 7 am and 5 pm is 10 hours(5+5).

(Spanish)

¿Qué es un reloj?

Un reloj, a menudo conocido como reloj, es un dispositivo que mide y muestra el paso del tiempo.

El reloj funciona en un período de tiempo de 12 horas, por lo tanto, el tiempo entre las 7 am y las 12 pm es de 5 horas, de manera similar, el tiempo entre las 12 pm y las 5 pm es de 5 horas.

Así, el total de horas entre las 7 am y las 5 pm es de 10 horas (5+5).

Answer:

a = 9

b = 19

Step-by-step explanation:

DO B FIRST

The mean is the average of all the terms (numbers) in the sequence

To find the average you find the sum of the terms and divided the sum by the number of terms there are.

The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A

a = 17(10)-7-12-15-17-19-20-22-24-25

a = 170-161

a = 9

The median is found by taking the average of the two middle terms

Our middle terms are 17 and B

the median times 2 equals the sum of the two terms and then subtract the term you know from the sum

b = 18(2)-17

b = 36-17

b = 19

1. x=-2, x=0

So, the equation in factored form would be x(x+2)=0.

2. x=0, x=4

So, the equation in factored form would be x(x-4)=0.

3. x=-2, x=0, x=4

So, the equation in factored form would be x(x+2)(x-4)=0.

Answer:

10) 7 meters

11) 10 yards

12) 452.16 inches²

13) 235.5 meters²

14) 22608 centimeters²

15) 4220.16 centimeters²

16) 1177.5 centimeters²

17) 141.3 millimeters²

Step-by-step explanation:

10) The volume of a rectangular prism is calculated by multiplying the height, width, and length of the shape. In this question, we have the volume, the width, and height, but not the length. To find it, we can divide the width and height from the volume.

First, divide the width.

[tex]\frac{210}{5}[/tex] = 42

Next, the height.

[tex]\frac{42}{6}[/tex] = 7

The length of the shape is 7 meters.

----------------------------------------------------------------------------------------------------------------

11) For this question, we can do the same thing. Take the volume, then divide the length and width from it.

[tex]\frac{360}{6}[/tex] = 60

[tex]\frac{60}{6}[/tex] = 10

The height is 10 yards.

----------------------------------------------------------------------------------------------------------------

12) We have to find the volume of a cylinder. The formula for this is [tex]V=\pi r^2h[/tex]. We will use 3.14 for pi. The radius is 4 in and the height is 9 in. We can plug our values into the equation and solve.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](4²)(9)

V = 3.14(4²)(9)

V = 50.24(9)

V = 452.16

The volume is 452.16 inches².

----------------------------------------------------------------------------------------------------------------

13) We will use the same formula for this. Our radius is 5 m and the height is 3 m. Plug the values in and solve.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](5²)(3)

V = 3.14(5²)(3)

V = 78.5(3)

V = 235.5

The volume of this cylinder is 235.5 meters².

----------------------------------------------------------------------------------------------------------------

14) The radius of this cylinder is 15 cm. The height is 32 cm. Put these numbers into our formula.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](15²)(32)

V = 3.14(15²)(32)

V = 708.5(32)

V = 22608

The volume of this cylinder is 22608 centimeters².

----------------------------------------------------------------------------------------------------------------

15) The next cylinder has a radius of 8 cm and a height of 21 cm.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](8²)(21)

V = 3.14(8²)(21)

V = 200.96(21)

V = 4220.16

The cylinder has a volume of 4220.16 centimeters².

----------------------------------------------------------------------------------------------------------------

16) This cylinder has a radius of 5 cm and a height of 15 cm.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](5²)(15)

V = 3.14(5²)(15)

V = 78.5(15)

V = 1177.5

The volume is 1177.5 centimeters².

----------------------------------------------------------------------------------------------------------------

17) The dimensions of this cylinder are 3 mm and 15 mm.

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](3²)(15)

V = 3.14(3²)(15)

V = 9.42(15)

V = 141.3

The volume is 141.3 millimeters².

Answer:

13 units is the answer.

Step-by-step explanation:

points (8,-4) and (3,8)

We can rewrite the Pythagorean theorem as,

[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]

∴ distance between 2 points (8,-4) and (3,8) = 13 units.

Answer:

Between 150 and 200 seeds will sprout

Answer:

1000 children

Step-by-step explanation:

Find the total units of adults and children = 2 + 3 = 5

5 units = 5000

1 unit = 5000 ÷ 5 = 1000

100% ÷ 5 units = 20% each unit

3 units = 20% x 3 = 60%

Since we all know that 60% of the people are children and 40% of the children are girls...

60 - 40 = 20%

20% = 1000

Simply plug 3 into the equation.

[tex]f(3) = 3(3)^2+2(3) = 3(9) + 6 = 27 + 6 = 33\\\\\\f(3) = 33[/tex]

Answer:

Step-by-step explanation:

Plugin x = 3 in the function

f(x) = 3x² + 2x

f(3) = 3*(3)² + 2*3               {3² = 3*3 = 9}

     = 3*9 + 6

     = 27 + 6

f(3) = 33

Answer:

EF = 27

Step-by-step explanation:

(x + 34)/2 = 2x - 13

x+ 34 = 4x - 26

3x = 60

x = 20

EF = 2(20) -13 = 27

Answer:

11.  EF = 27

Step-by-step explanation:

11.

Median of a trapezoid:

2x - 13 = 20 + x + 14

                    2

2(2x - 13) = 20 + x + 14

4x - 26 = 34 + x

4x - x = 34 + 26

3x = 60

x = 20

EF = 2x - 13

EF = 2(20) - 13

EF = 40 - 13

EF = 27
