Answer:

The questions are

  1. What does the frequency column in the attached table sum to?
  2. What does the relative frequency column in attached table  sum to?
  3. What is the difference between relative frequency and frequency for each data value  in the attached table?
  4. What is the difference between cumulative relative frequency and relative frequency  for each data value in attached table?

The correct answers are

  1. 65
  2. 1
  3. The relative frequency gives the relative proportion of each frequency in the sample while
  4. The frequency is the observed number of count of each grouping has in a given sample size

Step-by-step explanation:

1. The frequency column in the attached column sums up to 65 because it is the total number of sales persons selected

2. The relative frequency column in the attached table sum up to 1 because it is the sum of the fractions of the individual frequencies to the total frequency

3. The difference between relative frequency and frequency for each data value is that

The relative frequency gives the relative proportion of each frequency in the sample while

4. The frequency is the observed number of count of each grouping has in a given sample size

Simplify (2z^5)(12z^3)/4z^4
Sphinxa [80]

Answer:

6z^{4}

Step-by-step explanation:

Given in the question an expression,

\frac{ (2z^5)(12z^3)}{4z^4}

Step 1

Apply exponential "product rule"

x^{m}x^{n}=x^{m+n}

\frac{ 12(2)z^5)(z^3)}{4z^4}

\frac{ (24)z^5)(z^3)}{4z^4}

\frac{ 24(z^{(5+3)})}{4z^4}

\frac{ 24(z^{8})}{4z^4}

Step 2

Apply exponential " divide rule"

\frac{x^{m}}{x^{n}}=x^{m-n}

\frac{24/4(z^{8})}{z^4}

\frac{6(z^{8})}{z^4}

\frac{6(z^{8-4})}{1}

6z^{4}

4✓6 × 3✓6<br>multiply and simplify <br>show work​
mafiozo [28]

Answer:

3

√

2

Explanation:

First put change the words into an equation:

√

3

×

√

6

Now you can multiply them together as you would normally multiply:

√

3

×

√

6

=

√

18

Now let's prime factor 18 and see if there are any squares that we can take out of it to simplify. All we have to see is if there are 2 numbers that are the same:

18

/ \

6

3

/ \

2

3

As you can see, we have a square:

3

×

3

=

9

So take

√

9

out of

√

18

. You should have:

√

9

√

2

But since

√

9

=

3

we can simplify further to make:

√

9

√

2

→

3

√
