Joe has a 1/2 probability of pulling a blue marble and 1/10 probability of pulling a red marble. 5/10+1/10= 6/10
6/10=3/5 there’s a 3/5 probability of pulling a blue than red marble
(i’m not sure if i completely understood i’m am very sorry if it’s wrong.)
Answer:
d. - 15
Step-by-step explanation:
The equation for direct variation is
y = kx
We know y =3 when x = -9
3 = k(-9)
Divide by -9
3/-9 = -9k/-9
-1/3 = k
The equation is then
y = -1/3 x
We know y = 5
5 = -1/3 x
Multiply each side by -3
-3*5 = -3*-1/3x
-15 = x
