Which choices are equivalent to the expression below? Check all that apply. 6√3
Westkost [7]

Answer:

case A. \sqrt{18}*\sqrt{6}

case B. \sqrt{108}

case E. \sqrt{3}*\sqrt{36}

Step-by-step explanation:

we have

6\sqrt{3}

we know that

6\sqrt{3}=\sqrt{36*3}=\sqrt{108}

<u>Verify each case</u>

case A) \sqrt{18}*\sqrt{6}

\sqrt{18}*\sqrt{6}=\sqrt{18*6}=\sqrt{108}

therefore

\sqrt{18}*\sqrt{6} is equivalent to 6\sqrt{3}

case B) \sqrt{108}

so

\sqrt{108} is equivalent to 6\sqrt{3}

case C) \sqrt{3}*\sqrt{6}

\sqrt{3}*\sqrt{6}=\sqrt{18}

therefore

\sqrt{18} is not equivalent to 6\sqrt{3}

case D) \sqrt{54}

so

\sqrt{54} is not equivalent to 6\sqrt{3}

case E) \sqrt{3}*\sqrt{36}

\sqrt{3}*\sqrt{36}=\sqrt{108}

therefore

\sqrt{3}*\sqrt{36} is equivalent to 6\sqrt{3}

case F) 108

so

108 is not equivalent to 6\sqrt{3}

djyliett [7]

Answer:

<em>5.5</em>

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

<em>Hence the midrange of the data is 5.5</em>
