The amount of money which is expected to lose if the game of spinner is played 1000 times is $111.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

You spin the spinner two times.

Let suppose there are total 12 outcomes on a spinner which has 12 blocks. In this block, 4 is blue. The probability of getting blue twice in this spinner and earning $15 is,

[tex]P=\dfrac{4}{12}\times\dfrac{4}{12}\\P=\dfrac{1}{9}[/tex]

The probability of not getting two blue in two spun and losing $2 is,

[tex]P^{-1}=1-\dfrac{1}{9}\\P^{-1}=\dfrac{8}{9}[/tex]

The money to expect to win or lose if you play this is,

[tex]E(X)=15\times\dfrac{1}{9}-2\times\dfrac{8}{9}\\E(X)=-0.111[/tex]

For 1000 games,

[tex]E(X)=-0.111\times1000\\E(X)=-111[/tex]

Thus, the amount of money which is expected to lose if the game of spinner is played 1000 times is $111.

Answer:

Solution

To solve the problem first we have simplify the improper fraction.

⇒ 33/4 ÷ 4 pounds.

= (4 × 3 + 3) /4 ÷ 4 pounds.

= 15/4 ÷ 4 pounds.

= 15/4 × 1/4 pounds.

= 15/16 pounds.

Now we know that, 1 pound = 16 ounces.

Therefore, 15/16 pounds .

= 15/16 × 16 ounces.

= 15/1

= 15

= 15 ounces.

Answer: 15 ounces.

3 3/4 pounds of rice divided equally in 4 containers.

the amount of ounces of rice each were in.

33/4 ÷ 4 pounds

= (4 × 3 + 3)/4 ÷ 4 pounds

= 15/4 ÷ 4 pounds

= 15/4 × 1/4 pounds

= 15/16 pounds

so, now:

1 pound = 16 ounces

hence, 15/16 pounds = 15/16 × 16 ounces

= 15 ounces

Answer:

Fraction: 23/18

Radians: 23π/ 18

Step-by-step explanation:

A semi circle is 180 degrees, so 230 degrees of a semi circle would be 230/180, or 23/18.

To convert degrees to radians, do the degree times π/180, so the answer is 23π/18

Hey there!

Answer:

center of the circle is (5, -3) and radius of the circle is 8 units

Step-by-step explanation:

Find the center of the circle given by this equation:

x²-10x+y²+6y-30=0

for x

b= -10

for y

b=+6

complete the square

for x

(-10/2)² = 25

for y

(6/2)²=9

x²-10x+25

y²+6y+9

(x²-10x+25)+(y²+6y+9)+30=0+25+9

(x²-10x+25)+(y²+6y+9)=25+9+30

(x-5)²+(y+3)²=64

This is the form of a circle. Use this form to determine the center and radius of the circle

(x − h)² + (y − k)² = r²

Circle Equation

(x-a)² + (y−b) ² = r² is the circle equation with a radius r, centered at (a, b)

Rewrite x² - 10x + y² + 6y - 30 = 0 in the form of the standard circle equation

(x − h)² + (y − k)² = r²

(x - 5)² + (y-(-3))² = 8²

(x-5)² + (y+3)² = 8²

r=8

h=5

k=-3

signs of h and k are opposite of what they are inside the parenthesis

Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x- offset from the origin, and k represents the y-offset from origin.

r=8

h=5

k=-3

thats the answer i think

Answer:

4 = 22

Step-by-step explanation:

Factor 40 into its prime factors

          40 = 23 • 5

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          4 = 22

Factors which will remain inside the root are :

          10 = 2 • 5

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          2 = 2

At the end of this step the partly simplified SQRT looks like this:

        2 • sqrt (10x4)  

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x8)=x4

    (3.2) sqrt(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x2•sqrt(x)

    (4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

     SQRT(x4) = x2

  sqrt (40x4) =

       2 x2 • sqrt(10)

Simplified Root :

2 x2 • sqrt(10)

Answer:

It's technically the same thing, because if we solve both of these the answer would be same.

First one says 70 percent part of 7 and the other one says 7 percent part of 70. However, if we solve both of these the answer will be same:

i) 70% of 7

= (70/100) × 7

= 4.9 answer

ii) 7% of 70

= (7/100) × 70

= 4.9 answer

So, here as you can see, through both the equations we get the same answer, which is 4.9 .

This is one of the basic principles of multiplication actually, where:

a × b = c

b × a = c

Therefore,

a × b = b × a

Answer:

Angle 6= 109
Angle 6= 71

Step-by-step explanation:

Angle 4 and Angle 2 are equal because they are vertical angles, Angle 2 is also 109, Angle 6 is corresponding to angle 2, meaning angle 6 is also 109. To figure out angle 7 you simply do 180-109=71 and you get 71 for angle 7

Answer:

Step-by-step explanation:

<6 is the same since they are alternate interior angles meaning <6 is 109 degrees

7 is going to be a little more complicated.

180-109=71

<1,2,3 and 4 all share similar angles. 1 and 3 are similar, meaning 2 and 4 are also.

If 2 is 4 (109), then this means that 7 is 109 as it is the alternate exterior angle.

Find length FD

FD is Opposite

BD adjacent

O + A is Toa

Tan20 = o/9

x9

9 x Tan20 = o

O = 3.2757.... (ans)

Opposite/ FD is 3.28cm to 2.p.d

Draw diagonal line from A to D & find its length - that's the hypotenuse of a right-angle created

Use Pythagoras Theorem

a^2 + b^2 = c^2

25^2 + 9^2 = c^2

Square root both sides to get c

C = root 25^2 + 9^2

= root 706

= 26.57066...(ans)

AD is 26.57cm

Now create another right-angle triangle A to F to D back to A.

Label dimensions found such as the Length of AD to be 26.57.. Plus, FD to be 3.28.

Use trig for angel FAD:

Opposite of triangle is 3.28

Adjacent is 26.57

So, OA means Toa, but we're after an angle & have to use tan inverse instead.

Tan-1 (3.28/26.57) = 7.0374..

So, the angle is 7.04 degrees.

(ans) - ignore, I did use rounded figures in my ans, I was originally not going to, but I did.

Another method to graph a line in the xy-axis or xy-plane is to use its intercepts. What are intercepts? These are points of the line that are found on the xx and yy axes. There are two kinds of intercepts.

The first one is called the x-intercept because it is the point of the line located on the horizontal axis (x-axis).

The second is the y-intercept which is the point of the line located on the vertical axis (y-axis).
