If you add up the close at 10pm numbers you get 60. Since the total number of people surveyed was 200 and the question asks if there were 4,000 you would divide 4,000 by 200 and you would get 20. Then you should multiply 60 by 20.

When you play darts, you know three darts at the board and add the scores. Bristoe and Clancy are practising. Here are the score

Alja [10]

The person who has a better average will be Clancy.

The person who has more varied scores is Bristoe.

<h3>How to calculate the average??</h3>

Bristoe - 18,32,26,53,5,29,41,15,85,9,44,28,100,37,55. The average will be the addition of the numbers as dividing by 15. This will be:

= 577/15

= 38.47

Clancy - 41,26,33,51, 26,29,60,45,60,19,42,36.

Average= 468/12

= 39

The person who has a better average will be Clancy.

The person who has more varied scores is Bristoe.

Write as an algebraic expression: Five times

Alenkasestr [34]

Given:

The statement is "Five times the difference of the cube of y and the square of x".

To find:

The algebraic expression for the given statement.

Solution:

We know that,

Cube = Power 3

Square = Power 2

Difference = Minus (-)

Times = Multiplication (×)

Now,

Cube of y = $y^3$

Square of x = $x^2$

Difference of the cube of y and the square of x = $y^3-x^2$

Five times the difference of the cube of y and the square of x is:

Required expression = $5(y^3-x^2)$

Therefore, the correct option is C. The required algebraic expression for the given statement is $5(y^3-x^2)$ .
