Answer:
2/3
Step-by-step explanation:
To find the probability, you first have to add up the total number of marbles in the bag.
3+4+9+5=21
Next you find the probability of getting a yellow:
9/21
Then you find the probability of getting a green:
5/21
And since the problem says "yellow <em>or</em> green" we will add the two together
9/21 + 5/21 = 14/21 = 2/3
Answer:
a+2b-d=1, 3, 5, 7
Step-by-step explanation:
(ax^2+bx+3)(x+d)
ax^3+bx^2+3x+adx^2+bdx+3d
ax^3+bx^2+adx^2+3x+bdx+3d=x^3+6x^2+11x+12
ax^3=x^3, a=1
bx^2+adx^2=6x^2
x^2(b+ad)=6x^2
b+ad=6
b+(1)d=6
b+d=6
------------
3x+bdx=11x
x(3+bd)=11x
3+bd=11
-----------------
b=6-d
3+(6-d)d=11
3+6d-d^2=11
3-11+6d-d^2=0
-8+6d-d^2=0
d^2-6d+8=0
factor out,
(d-4)(d-2)=0
zero property,
d-4=0, d-2=0
d=0+4=4,
d=0+2=2
b=6-4=2,
b=6-2=4.
------------------
a+2b-d=1+2(2)-2=1+4-2=5-2=3
-------------------
a+2(4)-4=1+8-4=9-4=5
-----------------------
a+2(2)-4=1+4-4=5-4=1
-----------------------
a+2(4)-2=1+8-2=9-2=7
Answer:
6.12
1.39
4.12
12
Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by 
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is 
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is 
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is 
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is
