Answer:

The expected net gain to the player for one play is -$0.0526.

Step-by-step explanation:

To find the expected net gain, we multiply each outcome by its probability:

Player wins:

Earns $35.

1 out of 38 numbers, so probability 1/38.

Player loses:

Loses $1.

37 out of 38 numbers, so probability 37/38.

Expected value:

[tex]\frac{1}{38} \times 35 - \frac{37}{38} \times 1 = -\frac{2}{38} = -0.0526[/tex]

The expected net gain to the player for one play is -$0.0526.

y = 2x

Step-by-step explanation:

( 0 , 0 ) ( 10 , 20)

Slope = Change in y ÷ change in x

         [tex]= \frac{20-0}{10-0}\\\\=\frac{20}{10}\\\\=2[/tex]

m= 2; (0,0)

y - y1 =m(x - x1)

y - 0 = 2(x - 0)

    y = 2x

Answer:

y= 2/1x + 0

So.. its 20 rise, run 10 or 20/10

Get two points from the graph (10,20) and (20,40)

y2-y1  40-20= 20

x2-x1  20-10 = 10

Answer:

6.3 sq ft

Step-by-step explanation:

Area of entire Δ = 1/2·(4)(1.9+3.1)

                           = 2(5)

                           = 10 sq ft

Area of unshaded Δ = 1/2 ·(4)·(1.9)

                                  = 2(1.9) =3.8 sq ft

Area of shaded Δ = 10.0 - 3.8 = 6.2 sq ft

Answer:

Z=8 is the answer

Step-by-step explanation:

first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8

Step-by-step explanation:

[tex] \tt{5z - 8 = 32}[/tex]

We want to remove the 8 first.

Step 1 : Since the original equation is minus 8 , we are going to use the opposite operation and add 8 to both sides.

⟶ [tex] \tt{5z - 8 + 8 = 32 + 8}[/tex]

Simplify -8 + 8 = 0 on the left. 32 + 8 = 40 on the right. Then we need to think about how to remove the coefficient 5.

⟶ [tex] \tt{5z = 40}[/tex]

Step 2 : Since the opposite of multiplication is division , we are going to divide both sides by 5.

⟶ [tex] \tt{ \frac{5z}{5} = \frac{40}{5}} [/tex]

Simplify. 5 / 5 = 1 on the left. 40/5 = 8 on the right. So , our answer is z = 8.

⟶ [tex] \tt{z = 8}[/tex]

[tex] \pink{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{z = 8}}}}}}}[/tex]

Answer:

r = 4 units

Step-by-step explanation:

From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.

Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.

Here, x - coordinate is - 4

Since radius is a non negative number.

So, r = 4 units

Answer:

286

Step-by-step explanation:

Given :

Mean (m) = 284

Standard deviation (s) = 5.5

P(Z > x) = 0.34

According to the standardized formula :

Zscore = (x - m) / s

Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412

Hence, Zscore = 0.412

Zscore = (x - m) / s

0.412 = (x - 284) / 5.5

5.5 * 0.412 = x - 284

2.266 = x - 284

x = 2.266 + 284

x = 286.266

x = 286 (nearest whole number)

Answer:

See attached image for the requested graph

Step-by-step explanation:

The values completed in the table and text boxes as shown, are all correct.

For the plotting of the points and drawing of the line, please see the attached image.

a. By putting the value of x one by one table can be completed

The complete table is attached below.

b. The graph is attached below.

c. solution of the given equation is x = 1.5.

Use the concept of fucntion which is defined as:

A relation between a collection of inputs and outputs is known as a function.

A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

The given fucntion is:

y = 6 - 2x

Since we know that this equation has degree one,

Therefore, it represents the equation of a line

Now to complete the table put the value of x in the fucntion one by one:

Put x = 0:

y = 6 - 2(0)

y = 6

Put x = 1:

y = 6 - 2(1)

y = 4

Put x = 2:

y = 6 - 2(2)

y = 2

Put x = 3:

y = 6 - 2(3)

y = 0

Put x = 4:

y = 6 - 2(4)

y = -2

Put x = 5:

y = 6 - 2(5)

y = -4

b. Now with the help of this table draw the graph of this fucntion.

The graph of it is attached below.

c. To solve the equation:

6-2x  = 3

Subtract 6 on both sides,

-2x = -3

Divide both sides by -2 we get.

x = 1.5

Hence,

The solution of the given equation is 1.5.

Answer:

y = ½x

_____

k = ½

Step-by-step explanation:

[# of donuts] 2 → [total price] $1

[# of donuts] 12 → [total price] $6

[# of donuts] 3 → [total price] $1.50

[# of donuts] 7 → [total price] $3.50

Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.

Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.

C 0759, 1518

Step-by-step explanation:

The numbers which represent the first 2 students selected is the option D.) 0759, 1019.

Random number table are a table of numbers arranged in an unpredictable sequence. These tables are used to select a random sample in certain situations.

We have the line in the random table as,

24000  75983  62200  91518  10198  88936

There are 1020 students in total.

So we have to select four digit numbers of the sequence 0001, 0002, ..........., 1019, 1020.

Any number which is not included in this interval will not be selected.

From the reference line given, the four digit numbers are,

2400, 0759, 8362, 2009, 1518, 1019, 8889, ...

From this line, mark the numbers included in our interval from 0001 to 1020.

The numbers are 0759 and 1019. Other numbers are not included in our required interval.

Hence the first 2 students will represent as the numbers 0759 and 1019.

For positive integers: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 For all integers: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 For Gaussian integers: ± 1 ± 3 i and ± 3 ± i (all combinations of signs) Explanation: A prime number is a number whose only factors are itself, units and unit multiples of itself. So in the positive integers, the first few primes are: 2 , 3 , 5 , 7 , 11 , ... So the smallest composite positive integer with the five smallest prime positive integers as factors is: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 If we extend our interest to include negative integers, then the smallest primes are: 2 , − 2 , 3 , − 3 , 5 , − 5 , ... So the smallest composite integers with the five smallest prime integers as factors are: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 If we consider Gaussian integers, then the smallest primes are: 1 + i , 1 − i , − 1 + i , − 1 − i , 1 + 2 i , 1 − 2 i , − 1 + 2 i , − 1 − 2 i , 2 + i , 2 − i , − 2 + i , − 2 − i , 3 , − 3 ,...
