Suppose the dial on the spinner is spun 2 times in a row.
Ivenika [448]

The probability of one success and one failure will be 4/9. Table C represents the probability distribution for the variable X.

<h3>What is probability?</h3>

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

The dials on the spinner are spun 2 times in a row.

P(dial lands on region)=P(success) = 2/3

P(failure) = 1/3

The probability that the two times dials on the spinner are not spun 2 times in a row.

P = (1/3)² = 1/9

The probability that the two times dials on the spinner are spun 2 times in a row.

P = (2/3)²= 4/9

One may calculate the probability of one success and one failure using the binomial distribution or by simply deducting the probabilities we previously determined from 1.

P = 1 - 1/9 - 4/9

P = 4/9

The probability of one success and one failure will be 4/9.

Hence table C represents the probability distribution for the variable

X.

What is the simplest radical form of the expression? (x3y5)4/3
VikaD [51]

Rational exponents work as follows:

a^{\frac{b}{c}}=\sqrt[c]{a^b}

So, in your case, we have

(x^3y^5)^{\frac{4}{3}} = \sqrt[3]{(x^3y^5)^4}=\sqrt[3]{x^{12}y^{20}}=\sqrt[3]{x^{12}y^{18}\cdot y^2}}=x^4y^6\sqrt[3]{y^2}

Find the measure of side c. Triangle A B C has a right angle at angle C. The measure of angle A is 29 degrees. Hypotenuse A B is
Pavel [41]

Given:

In triangle ABC, right angle at angle C.

a = 33 meters

m\angle A=29^\circ

To find:

The measure of side c.

Solution:

In a right angle triangle,

\sin \theta =\dfrac{Perpendicular}{Hypotenuse}

It is also written as:

\sin \theta =\dfrac{Opposite}{Hypotenuse}

In triangle ABC, angle C is a right angle. It means the side c is the hypotenuse.

In triangle ABC,

\sin A=\dfrac{a}{c}

\sin 29^\circ=\dfrac{33}{c}

c=\dfrac{33}{\sin 29^\circ}

On further simplification, we get

c=\dfrac{33}{0.4848}

c=68.0693

c\approx 68.07

Therefore, the measure of side c is 68.07 meters.
