Answer:
a : b : c = 12 : 10 : 15
Step-by-step explanation:
Given that: b = of c
i.e b = ............... 1
2c = 5b
So that;
c = .................... 2
Also,
4a = 3c
a = ................ 3
⇒ a = × ()
a = ................. 4
15b = 8a
b = ................. 5
Comparing the derived equations:
From equations 2 and 3,
a:c = : = 4:5
From equations 1 and 2,
b:c = : = 2:3
But a common value of b = 15, gives;
a : c = 12 : 15 and b : c = 10 : 15
Thus, a : b : c = 12 : 10 : 15
T^2-t=12
t^2-t-12=0
(t-4)(t+3)=0
t=4, -3
<span>B.You reach into a basket and draw a name for a prize, return the name into the basket, and then draw a second time for another prize.
The results of the prizes in the first basket are not related at all to what happens in the second basket. So these two events are independent.
Hope this helps :)</span>
