Answer:

The final answer is \frac{8}{27} .

Step-by-step explanation:

Solve the following equation:

(2^{2} \cdot 3^{-1} \cdot 4^{-1})^{-1} \over 2^{-3} \cdot 3^{4}

-Simplify 2^{2} :

(2^{2} \cdot 3^{-1} \cdot 4^{-1})^{-1} \over 2^{-3} \cdot 3^{4}

(4 \times 3^{-1} \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

-Simplify 3^{-1} :

(4 \times 3^{-1} \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

(4 \times( \frac{1}{3}) \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

-Multiply both 4 and \frac{1}{3} :

(4 \times( \frac{1}{3}) \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

(\frac{4}{3} \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

-Simplify 4^{-1} :

(\frac{4}{3} \times 4^{-1})^{-1} \over 2^{-3} \times 3^{4}

(\frac{4}{3} \times (\frac{1}{4}) )^{-1} \over 2^{-3} \times 3^{4}

-Multiply both \frac{4}{3} and \frac{1}{4} together:

(\frac{4}{3} \times (\frac{1}{4}) )^{-1} \over 2^{-3} \times 3^{4}

(\frac{1}{3})^{-1} \over 2^{-3} \times 3^{4}

-Simplify \frac{1}{3}^{-1} :

(\frac{1}{3})^{-1} \over 2^{-3} \times 3^{4}

3 \over 2^{-3} \times 3^{4}

-Then, on the denominator,  simplify 2^{-3} :

3 \over 2^{-3} \times 3^{4}

3 \over \frac{1}{8}  \times 3^{4}

Simplify 3^{4} :

3 \over \frac{1}{8}  \times 3^{4}

3 \over \frac{1}{8}  \times 81

Multiply both \frac{1}{8} and 81 together:

3 \over \frac{1}{8}  \times 81

3 \over \frac{81}{8}

Divide 3 and \frac{81}{8} by multiplying 3 by the reciprocal of \frac{81}{8} :

3 \over \frac{81}{8}

3 \times (\frac{81}{8})

-And you multiply 3 and \frac{81}{8} together:

3 \times (\frac{81}{8})

\frac{8}{27}

So, the final answer would be \frac{8}{27} .

Mekhanik [1.2K]

Answer: 0.8413

Step-by-step explanation:

Given : Henry has collected data to find that the typing speeds for the students in a typing class has a normal distribution.

Mean : \mu=47

Standard deviation : \sigma= 4

Let x be the random variable that represents the typing speeds for the students.

The z-score :-

z=\dfrac{x-\mu}{\sigma}

For x= 51

z=\dfrac{51-47}{4}=1

Using the standard normal distribution table ,the probability that a randomly selected student has a typing speed of less than 51 words per minute :-

P(x

Hence, the probability that a randomly selected student has a typing speed of less than 51 words per minute = 0.8413

Which of the statements are true regarding dot plots bar graphs and historgrams
andrey2020 [161]

the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".

<h3>Which of the statements are true regarding dot plots, bar graphs, and histograms?</h3>

Dot plots,  bar graphs, and histograms are used to repersent graphically data sets.

Thus, what these graphs do represent are populations in a data set with a given property.

Remember that data is usually discrete, so we usually use dot plots and bar graphs to represent discrete data.

Histograms show distributions of numerical data (it can be used for continuous or discrete data).

With all that in mind, we conclude that the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".
