What is the question

If Benito is selecting samples of five values from the table, which row will result in the greatest mean? Population Data Row 1
Vilka [71]

Answer:

4th row will result in the greatest mean.

Step-by-step explanation:

We are asked to find the row with greatest mean from our given rows.

We will use formula \bar{x}=\frac{\Sigma x}{n}, where,

\bar{x}=\text{Mean},

\Sigma x=\text{Sum of all data values},

n=\text{Number of data points in sample}

Let us find mean of each row using above formula.

\text{Mean of row 1}=\frac{4+2+2+3+3}{5}

\text{Mean of row 1}=\frac{14}{5}

\text{Mean of row 1}=2.8

Therefore, mean of 1st row is 2.8.

\text{Mean of row 2}=\frac{3+3+4+3+2}{5}

\text{Mean of row 2}=\frac{15}{5}

\text{Mean of row 2}=3

Therefore, mean of 2nd row is 3.

\text{Mean of row 3}=\frac{2+4+3+4+3}{5}

\text{Mean of row 3}=\frac{16}{5}

\text{Mean of row 3}=3.2

Therefore, mean of 3rd row is 3.2.

\text{Mean of row 4}=\frac{3+4+4+7+3}{5}

\text{Mean of row 4}=\frac{21}{5}

\text{Mean of row 4}=4.2

Therefore, mean of 4th row is 4.2.

Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.

Can someone help me with this please
skad [1K]

Answer:

the answer is: 6z^3

Step-by-step explanation:

We need to solve this equation:

\sqrt{36z^6}

We know that 6X6 = 36

and √ = 1/2

Solving:

=\sqrt{6*6*z*z*z*z*z*z}\\We\,\,know\,\,6X6=6^2\,\, and \,\,z*z=z^2\\=\sqrt{6^2*z^2*z^2*z^2} \\=(6^2)^{1/2}*(z^2)^{1/2}*(z^2)^{1/2}*(z^2)^{1/2}\\=6*z*z*z\\=6z^3

So, the answer is: 6z^3

Kareendeep has $168.50 in her bank account. She buys x shirts for $5.5o each. Write and solve an equation Kareendeep can use to
Vikentia [17]

Answer:

Equation: 5.5x = 168.5

Solution: 30 shirts

Step-by-step explanation:

First, create the equation where x is the number of shirts.

Since each shirt is $5.50, the cost of the shirts will be 5.50x

Set this equal to 168.50, since that is how much money Kareendeep has.

So, the equation will be 5.5x = 168.5

Now, solve this for x, the number of shirts she can buy:

5.5x = 168.5

Divide each side by 5.5

x = 30.6

Since we can only have a whole number of shirts, she can only buy 30 shirts.

So, the answer is 30 shirts.
