Let the token profit be X. For a win, the profit is 2 tokens. For a loss, the profit is -3 tokens. The probability of a win is <span><span>212</span>+<span>212</span>+<span>212</span>=<span>612</span>=<span>12</span></span> the probability of a loss is <span><span>612</span>=<span>12</span></span> Setting up a probability distribution variable gives: <span>E(X)=(−3×<span>12</span>)+(2×<span>12</span>)=−1<span>12</span>+1=−<span>12</span> token</span><span> Therefore, on average, the player would expect to lose a half a token per game.</span>

Is 3/x+4/y=2 linear or non-linear

Eduardwww [97]

The given equation is non-linear.

Solution:

Given expression is $\frac{3}{x} +\frac{4}{y} =2$ .

To find the equation is linear or non-linear.

Linear equation is a straight line which is in the form ax + by + c = 0.

Otherwise it is non-linear equation.

⇒ $\frac{3}{x} +\frac{4}{y} =2$

Do cross multiply for the fractions to make the denominators same.

⇒ $\frac{3y}{yx} +\frac{4x}{yx} =2$

⇒ $\frac{3y+4x}{yx} =2$

Do cross multiplication.

⇒ $3y+4x=2yx$

⇒ $4x+3y-2yx=0$

Here, there is no constant term.

So, the equation is not a straight line.

Hence, the given equation is non-linear.

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x

laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line $y=7x$ is $y=7x-12$

Step-by-step explanation:

Given:

a line $y=7x$

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

$y=7x$ ...........Given

Comparing with,

$y=mx$

Where m =slope

We get

$Slope = m = 7$

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

$(y-y_{1})=m(x-x_{1})$

Substituting the points and so we will get the required equation of the line,

$(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line$

Therefore, equation of the line that passes through (2,2) and is parellel to the line $y=7x$ is $y=7x-12$
