The probability of landing on red the first time is 1/2, because there are two colors on the wheel. The probability of landing on blue the second time in that individual round is 1/2. The probability of landing on red the third time in that individual round is 1/2.

Multiply 1/2 by 1/2 by 1/2

Answer: The probability is 1/8

Solve the simultaneous equations, 2x+4y = 1
GarryVolchara [31]
For a solution to exist the x and y values must be equal at that point.

I'll solve both for y first (and there are other ways to do this of course)

2x+4y=1, 4y=1-2x, y=(1-2x)/4

3x-5y=7, -5y=7-3x, y=(3x-7)/5

Since y=y at the solution point we can say:

(1-2x)/4=(3x-7)/5  cross multiplying...

5-10x=12x-28

-22x=-33

x=3/2 or if you prefer 1.5, now we can solve for y using either origianl equation...

2(1.5)+4y=1

3+4y=1

4y=-2

y=-0.5

So the solution is the point (1.5, -0.5)

A car entered a roundabout from Mason Avenue, traveled 280 feet, then turned onto Perry Street. If the roundabout has a diameter
Rama09 [41]

Answer:

The angle of rotation is 214°.

Step-by-step explanation:

Formula for arc length:

The length of arc is the product of radius and the central angle ( in radian).

L= rθ

L= Length of arc

r= Radius

θ= Central angle (in radian).

Here L= 280 feet and diameter =150 feet.

Radius =\frac{150}{2} feet =75 feet

L= rθ

\Rightarrow \theta =\frac{L}{r}

\Rightarrow \theta =\frac{280}{75} radian.

We know that,

π  radian= 180°

\Rightarrow 1 \ radian= \frac{180^\circ}{\pi}

\Rightarrow \frac{280}{75} \ radian = \frac{180^\circ}{\pi}\times  \frac{280}{75}

                      = 214°

The angle of rotation is 214°.

GIVING BRAINLIEST!!
sergij07 [2.7K]

Answer:

It would cost <em>n</em> people $<em>nd</em> to play Decimal Decisions and $<em>nr</em> to play Ratio Rage. So, it would cost <em>n</em> people $<em>nd</em> + $<em>nr</em>= $2<em>n</em>(<em>d</em> + <em>r</em>).

<em>d</em>= Decimal Decisions and <em>r</em>= Ratio Rage

You didn't give a price for either game, so I just did variables in place of actual cost. Hope this helps!
