Answer: Option 'A' is correct.

Step-by-step explanation:

In the binomial probability formula, we have

P(X=x)=^nC_xp^{x}q^{n-x}

Here, n = number of events

x = number of trials

p = probability of success

q = probability of failure

x is the number of trials among which we decide the number of successes and number of failures.

So, Option 'A' is correct.

Write -3/4x-6 in standard form using integers
taurus [48]

Answer:

3x+4y=-24

Therefore, option C is correct.

Step-by-step explanation:

We have been given the equation:

y=\frac{-3x}{4}-6[/

We will take LCM 4 on right hand side of the above equation:

y=\frac{-3x-24}{4}

Now, we will multiply the 4 in denominator on right hand side to the y in left hand side pof the equation we get:

4y=-3x-24

After rearranging the terms we get:

3x+4y=-24

Therefore, option C is correct.

Which rule describes the composition of
ExtremeBDS [4]

Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.

If
arlik [135]

Given:

In a right angle triangle θ is an acute angle and \tan\theta =\dfrac{3}{5}.

To find:

The value of \cos \theta.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

We have,

\tan\theta =\dfrac{3}{5}

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

Hypotenuse=\sqrt{Perpendicular^2+base^2}

Hypotenuse=\sqrt{(3x)^2+(5x)^2}

Hypotenuse=\sqrt{9x^2+25x^2}

Hypotenuse=\sqrt{34x^2}

Hypotenuse=x\sqrt{34}

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

\cos \theta=\dfrac{5x}{x\sqrt{34}}

\cos \theta=\dfrac{5}{\sqrt{34}}

Therefore, the value of \cos \theta is \dfrac{5}{\sqrt{34}}.

The area of a circle is A=πr².

Plug 3 in for the radius.

A=π(3²)

A=9π ft²,

or using 3.14 for pi,

Approximately 28.26 ft².
