Step-by-step explanation:
y = -5x² + 2x - 3 and y = -3x - 3.
=> -5x² + 2x - 3 = -3x - 3
=> 5x² - 5x = 0
=> 5x(x - 1) = 0
=> x = 0 or x = 1.
When x = 0, y = -3(0) - 3 = -3.
When x = 1, y = -3(1) - 3 = -6.
The solutions are (0,-3) and (1,-6).
Answer:
4/11
Outcomes that meet your requirement are
(1, 6), (2, 6), (6, 1), (6, 2)
for a total of 4 favorable outcomes.
There are 11 outcomes in which one die shows a 6.
So your probability would be 4/11.
The median
It uses all the added numbers as one
8(5*3)+(2*5)+(2*10)=360
8(15)+(10)+(20)=
8(45)=
