<u>Answer choice:</u> D) 3/25
Answer:
Third answer shown
Step-by-step explanation:
Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.
x + 3 = -2x + 6
Add 2x to both sides. 2x 2x
3x + 3 = 0 + 6
3x + 3 = 6
Subtract 3 on both sides. -3 -3
3x = 3
Divide both sides by 3. x = 1
Now, let's see what y must be if x equals 1.
Line M: y = x + 3 --> y = 1 + 3 --> y = 4
Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed
So the ordered pair (x, y) that satisfies <u><em>both </em></u>equations is (1, 4)
*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.
That is the third answer shown.
I’m pretty sure the answer to that is b
Answer:
Step-by-step explanation:
A two 6 sided die is rolled
Sample space would be (1,1)...(1,6)....(6,1)....(6,6)
Let x be the sum obtained
X can take values as 2 or 3 ....12
P(x=12) = P(6,6) =1/36
P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36
P(2) =P(1,1) = 1/36
For other outcomes no payment
Thus we can list this as
Sum 2 3 4 5 6 7 8 9 10 or 11 12
Prob 1/36 5/36 1/36
Gain 3 0 0 0 0 0 0 0 50 100
E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36
E(gain) = total= 353/36
Cost of game = 6
E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6
= 3.806
