A carnival has a ring-toss game where players try to toss rings around a stick. A player gets two attempts in a game. Let X repr

esent the number of rings a randomly chosen customer successfully tosses around the stick in a game. Based on previous data, here's the probability distribution of X along with summary statistics:
X=\text{\# of successes}X=# of successesX, equals, start text, \#, space, o, f, space, s, u, c, c, e, s, s, e, s, end text 000 111 222 P(X)P(X)P, left parenthesis, X, right parenthesis 0.900.900, point, 90 0.080.080, point, 08 0.020.020, point, 02 Mean: \mu_X=0.12μ X ​ =0.12mu, start subscript, X, end subscript, equals, 0, point, 12 Standard deviation: \sigma_X\approx0.38σ X ​ ≈0.38sigma, start subscript, X, end subscript, approximately equals, 0, point, 38
A player wins 10 tickets for each successful toss. Let T represent the number of tickets a randomly chosen players wins in a game. What are the mean and standard deviation of T?

Answer:

6 inches

Step-by-step explanation:

Formula for surface area of a cylinder:

SA=2\pi r^{2} +2\pi rh

Plug in values and solve for the radius:

180\pi =2\pi r^{2} +2\pi r(9)\\

Divide both sides by 2\pi

90=r^{2} +r(9)

Subtract 90 from both sides

0=r^{2} +9r-90

Use the quadratic equation to find the roots

x=(-b±\sqrt{b^2-4ac})*\frac{1}{2a} (sorry for formatting, Brainly doesn't

                                           allow equations with ± in them)

x=\frac{-9+\sqrt{9^2-4*1*90} }{2(1)}        and          x=\frac{-9-\sqrt{9^2-4*1*90} }{2(1)}

x=\frac{(-9+\sqrt{81+360})}{2}          and          x=\frac{(-9-\sqrt{81+360})}{2}

x=\frac{(-9+\sqrt{441})}{2}               and          x=\frac{(-9-\sqrt{441})}{2}

x=\frac{(-9+21)}{2}                   and          x=\frac{(-9-21)}{2}

x=\frac{12}{2}                           and          x=\frac{-30}{2}

x=6                             and          x=-15  

We can't have a negative radius, so that leaves us with r=6 in.

What is the general form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)?
yawa3891 [41]
The equation of circle is:
(x-a)^2+(y-b)^2=r^2 where C(a, b) is the center.
In order to find r you have to find the distance between C(-2, 1) and let's say A(-4, 1)

The formula for distance is:
\sqrt{  ( y_{A}-y_{C )^{2} + (x_{A}- x_{C )^{2} }
r = 2

The equation of circle is
(x+2)^2+(y-1)^2=4

I hope that this is the answer that you were looking for and it has helped you.

Determine the slope <br><br> 2y-4x=1
Maurinko [17]

Answer:

2

Step-by-step explanation:

The equation is mx+b=y

The equation is not simplified yet.

2y-4x=1

Add 4x to both sides

2y=1+4x

Divide by 2

1/2+2x

For this just identify. M=slope. The number next to the x is 2. So the answer is 2
