Start: 21.5
After Tacos: 21.5*(1-1/4)=21.5*(3/4)=16.125
Used For Burgers: 16.125*(2/3)=10.75
Burgers: 10.75/(1/4)=10.75*4=43
Answer:
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Step-by-step explanation:
The addition rule of probability is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A ∪ B) is probability A or B , P(A ∩ B) is probability A and B
∵ P(A) = 0.33
∵ P(B) = 0.6
∵ P(A ∩ B) = 0.248
- Substitute these values in the rule above
∴ P(A ∪ B) = 0.33 + 0.6 - 0.248
∴ P(A ∪ B) = 0.682
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Answer:
15.4
Step-by-step explanation:
3(9+3⋅8)−23
3(12.8)-23
38.4-23
15.4
So the answer is15.4
Simplify terms, then move the terms over so 'y' is by itself.
-7y-0.6=3.6-y
-0.6-3.6=-y+7y
-4.2=6y
y=-4.2/6
y= -0.7
