<u>Center and Radius</u>
3x² + 3y² + 30x - 42y - 141 = 0
x² + y² + 10x - 14y - 47 = 0
x² + 10x + y² - 14y - 47 = 0
x² + 10x + 25 + y² - 14y - 49 = 0
x² + 10x + 25 + y² - 14y - 49 = 47
x² + 10x + 25 + y² - 14y + 49 = 47 + 25 + 49
x² + 10x + 25 + y² - 14y + 49 = 121
(x + 5)² + (y - 7)² = 121
center: (-5, 7)
radius: 11

Tom says that he needs 6 rolls to obtain each possible outcome on a 6-sided die. On the fourth roll, he rolls his second "3". To
Anna11 [10]

Answer:

Tom is incorrect

Step-by-step explanation:

The odds of getting any number on a 6-sided die are 1:6

Every time he rolls, there is a 1:6 chance he gets any number.  Therefore, it is totally plausible to get the same number again.  As the number of rolls tends toward infinity, the ratio of each number occurring to number of rolls equals 1:6.

galben [10]
Hey! 
So when there is a scale factor you would always multiply it with the original dimensions, even if it wasn't a fraction.
so 4 time 1/5 is 0.8
and 6 times 1/5 is 1.2
so the dimensions of the model bed is 0.8 foot by 1.2 feet
Your answer is A!
Hope this helps!
