Answer: The percent error in the player's guess is 9.5%.

Step-by-step explanation:

Given : A basketball player guesses her team will score 57 points during the game.

The player's team actually scores 63 points.

i.e. The actual core = 63 points

The estimated score = 57 points

Then , the percent error in the player's guess would be :

=\dfrac{|\text{Estimated score-Actual score}|}{\text{Actual score}}\times100\\\\=\dfrac{|57-63|}{63}\times100\\\\=\dfrac{|-6|}{63}\times100\\\\=\dfrac{6}{63}\times100=9.52380952381\%\\\\\approx9.5\%

Hence, the percent error in the player's guess is 9.5%.

U(-3,6), V(-8, 1), W(-3,1)<br> 180° rotation about the origin
Ad libitum [116K]

Answer:

<em>U'</em>(3, -6), <em>V</em><em>'</em>(8, -1), <em>W</em><em>'</em>(3, -1)

Step-by-step explanation:

According to the <em>180°-rotation rule</em>, you take the OPPOSITE of both the y-coordinate and x-coordinate:

<u>Extended Rotation Rules</u>

270°-clockwise rotation [90°-counterclockwise rotation] >> (x, y) → (-y, x)

270°-counterclockwise rotation [90°-clockwise rotation] >> (x, y) → (y, -x)

180°-rotation >> (x, y) → (-x, -y)

I am joyous to assist you anytime.

Which expression is NOT equivalent to the other three? A) −9 − 7n + 16n B) 9(n − 9) Eliminate C) n − 9 + 8n D) 9n − 9
yuradex [85]

Answer:

The expression is not equivalent to other three is 9(n-9) .

Option (B) is correct .

Step-by-step explanation:

Take first expression

= -9 -7n + 16n

= 9n-9

Take second expression

= 9(n-9)

= 9 × n - 9 × 9

= 9n - 81

Take third expression

= n-9+8n

= 9n-9

Take fourth expression

= 9n-9

Therefore expression is not equivalent to other three is 9(n-9) .

Option (B) is correct .
