Answer:
Red on the 5th draw = 0.0907
Step-by-step explanation:
The first to fourth selections are all the same.
Blue + white = 12 + 6 = 18
The total number of marbles is 11 + 12 + 6 = 29
P(~ red) for the first four times = (18/29)^4 = 0,1484
Now on the 5th time, the first red is 11/18
So the Probability is 0.1484 * 11/18 = 0.0907
(a). How much the T-shirt cost.
(b). 23=12+x
(c). 23-12=x; x= 11
(d) the T-shirt cost $11.
Answer:
4000 rounded about
Step-by-step explanation:
I don't like these computer choice thingies. It detracts from the math.
If we want to eliminate x we multiply the first equation by 5 then add it to the second:
OK, that's how it's done. Reading through the choices, that's choice D.
EDITED:
so lets make the question more clear
lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;
3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32
= THIS EQUALS 32
Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4 = THIS EQUALS 32
MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )
