The measure of x is  \angle x=24^{\circ}

Explanation:

It is given that $\angle x$ and $\angle y$ are supplementary angles.

The two angles are said to be supplementary if their angles add up to 180°

Thus, we have,

\angle x+\angle y=180^{\circ}

Also, it is given that \angle y=156^{\circ}

Substituting the value in the expression \angle x+\angle y=180^{\circ}, we have,

\angle x+$156^{\circ}$=180^{\circ}

Subtracting both sides by $156^{\circ}$, we get,

\angle x+$156^{\circ}$-156^{\circ}=180^{\circ}-156^{\circ}

                 \angle x=24^{\circ}

Thus, the measure of x is \angle x=24^{\circ}

The probability that Roger wins a tennis tournament (event A) is 0.45, and the probability that Stephan wins the tournament (eve
Svetllana [295]

Answer:

Hence, option (3) is correct.

Step-by-step explanation:

The probability that Roger wins a tennis tournament (event A) is 0.45 i.e. P(A)=0.45

The probability that Stephan wins the tournament (event B) is 0.40 i.e. P(B)=0.40

The probability of Roger winning the tournament, given that Stephan wins, is 0 i.e. P(A|B)=0

The probability of Stephan winning the tournament, given that Roger wins, is 0 i.e. P(B|A)=0

We know that P(A|B)=\dfrac{P(A\bigcap B)}{P(B)}

⇒   P(A∩B)=0

But if A and B are independent events then P(A∩B)=P(A)×P(B)

Hence, P(A|B)=P(A)

Similarly P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}

Hence, if A and B are independent events then,

P(B|A)=P(B)

But in this situation such a thing is not possible.

Hence, option (3) is correct.

What is the completely factored form of 9x^2+24x+16
stepladder [879]
<span>The completely factored form of 9x^2+24x+16 is equal to
</span><span>9x^2+24x+16
(3x + 4) (3x + 4)

Since the two factors are the same, this can be simplified as
</span>(3x + 4) (3x +<span> 4)
</span>(3x + 4)^2

It is a perfect square factor.

Answer: 2x + 5y = -5

Step-by-step explanation:

Two lines are said to be parallel if they have the same slope.

The equation of the line given :

2x + 5y = 10

To find the slope , we will write it in the form y = mx + c , where m is the slope and c is the y - intercept.

2x + 5y = 10

5y = -2x + 10

y = -2/5x + 10/5

y = -2/5x + 2

This means that the slope is -2/5 ,the line that is parallel to this line will also have a slope of -2/5.

using the formula:

y-y_{1} = m (x-x_{1} ) to find the equation of the line , we have

y - 1 = -2/5(x -{-5})

y - 1 = -2/5 ( x + 5 )

5y - 5 = -2 ( x + 5 )

5y - 5 = -2x - 10

5y + 2x = -10 + 5

therefore :

2x + 5y = -5 is the equation of the line that is parallel to 2x + 5y = 10
