Answer:

A. x²+x-11

Step-by-step explanation:

Take one of the x values and try them out on all formulas to see if the expected output occurs.

Already with x=2 you get

-5, 28, -3, 27 so you know that only the first formula works.

What is the equation has intercepts at x(1, 0, 0), y(0, -1,0), and z(0, 0, 2)
bulgar [2K]

In intercept form, the plane that has these intercepts is ...

... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1

... x/1 + y/(-1) + z/2 = 1

... 2x -2y +z = 2 . . . . . in standard form

Suppose that you roll a pair of honest dice. If you roll a total of​ 6, you win​ $18; if you roll a total of​ 11, you win​ $72;
ser-zykov [4K]

You can roll a total of 6 by rolling (1, 5), (2, 4), (3, 3), (4, 2), or (5, 1). There are 36 total possible rolls that can be obtained, so you roll a total of 6 with probability 5/36.

You can roll a total of 11 by rolling (5, 6) or (6, 5), hence with probability 2/36 = 1/18.

Any of the other remaining 29 outcomes occurs with probability 29/36.

The expected value of your winnings is

$18*5/36 + $72*1/18 - $9*29/36 = -$0.75

so the answer is E.

A six-sided die with sides labeled 1 through 6 will be rolled once. Each number is equally likely to be rolled.
ivanzaharov [21]

Answer:

2/3

Step-by-step explanation:

The numbers greater then 2 are 3, 4, 5, 6

That's four numbers that are greater then two.

or 4/6, then you just reduce it by dividing by two on the top and bottom

4/2 =2

6/2 = 3                            so the answer is 2/3
