First change each term to its radical form and simplify.
2^(5/2)= sqrt(2^5)=4sqrt2
2^(3/2)= sqrt(2^3)=2sqrt2
Now subtract
4sqrt2 - 2sqrt2 = 2sqrt2

Which phrase can be represented by an equation? twice as much as a number 12 less than a number half of a number is 15 the diffe
jeka57 [31]

Answer:

Half of a number is 15

Step-by-step explanation:

First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.

An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.

Twice as much as a number:              2X

12 less than a number:                        X - 12

Half of a number is 15:                        X/2 = 15

The difference of 20 and a number: 20 - X

As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Butoxors [25]

The mean of a dataset is simply the sum of the elements, divided by how many elements you have.

In your case, you have a dataset of 10 elements, so we will divide by 10.

The sum of the elements is

5+8+9+11+7+7+8+9+12+7=83

Which implies that the average is

\dfrac{83}{10}=8.3

Which should be approximated to 8.
