Simplifly the expression 64^7/12
Evgesh-ka [11]

Answer:

8\sqrt{2}

Step-by-step explanation:

we have

64^{\frac{7}{12}}

we know that

64=2^{6}

substitute

64^{\frac{7}{12}}=(2^{6})^{\frac{7}{12}}\\ \\=(2)^{\frac{6*7}{12}} \\ \\=(2)^{\frac{7}{2}} \\ \\=\sqrt{2^{7}}\\ \\=2^{3}\sqrt{2} \\ \\=8\sqrt{2}

Rewrite this non-statistical question as a statistical question. How many minutes do I exercise each day?
stira [4]

Answer:

The statistical question should be

"how many minutes do I exercise on each day of the week" and "how many minutes do I exercise each day of the week whilst there is background music"

Step-by-step explanation:

Here we have the non statistical question, how many minutes do I exercise each day

We note that a statistical question is one in which there are are different variety answers, where the distribution and the inclination of the the answers is sought

Therefore, statistically, we should ask, "how many minutes do I exercise on each day of the week" or "how many minutes do I exercise each day of the week whilst there is background music".

X^4=15 <br> is an exponential equation?
miskamm [114]

Answer:

No. It is not an Exponential Equation.

Step-by-step explanation:

Givenx^{4} =15

By the Definition of Exponential Equation which states.

"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."

For Example:

All given below are said to be exponential equations.

5^{x} =5^{2} \\7^{x}=49\\

which can be rewritten as

7^{x}=7^{2}

Now in the given equation x^{4}=15 it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation

The lengths, in minutes, of the movies currently showing at a movie theater are shown in the data set. ​ ​ ​ ​Create a histogram
alexdok [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required lengths are not given.

I will use the following data set to answer the question.

Dataset: 35, 51, 39, 42, 68, 62, 32, 59

First, is to determine the range of the dataset

Range = Highest - Least

Range = 68 - 32

Range = 36

Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval

Class= Range/10

Class = 36/10

Class = 3.6

Class \approx 4

<em>So, we use 4 classes</em>

Plot the frequency distribution table as follows:

\begin{array}{ccc}{Intervals} & {Observations} & {Frequency} & {31-40} & {32,35,39} & {3} & {41-50} & {42} & {1} & {51-60} & {51,59} & {2} & {61-70} & {62,68} & {2}\ \end{array}

<em>See attachment for histogram</em>
