Answer:
a. 0.58
b. 0.78
Step-by-step explanation:
a. The probability of egg come from B1 or B2
P(B1) = 3000/10000 = 0.3
P(B2) = 4000/10000 = 0.4
P(P1 ∪ B2) = 0.3 + 0.4 -(0.3)(0.4)
P(P1 ∪ B2) = 0.7 - 0.12
P(P1 ∪ B2) = 0.58
b. The probability that the market received an egg that is acceptable
P(received an egg that is acceptable) = P(B1 acceptable) + P(B2 acceptable) + P(B3 acceptable)
P(received an egg that is acceptable) = 0.80*3000 + 0.90*4000 + 0.60*3000 / 10000
P(received an egg that is acceptable) = 2400 + 3600 + 1800 / 10000
P(received an egg that is acceptable) = 7800 / 10000
P(received an egg that is acceptable) = 0.78
Answer:
y=2 and x=1
Step-by-step explanation:
sub 2 into 1
3(15-7y) + 4y= 11
45 - 21y +4y =11
-21y+4y= 11-45
-17y= - 34
y=2
Therefore sub y into x equation
x=15-7(2)
x= 1
Answer:
(-45,45,14)
Step-by-step explanation:
(r+v)*w=((9,8,3)+(6,7,-1))*(-3,3,7)=(15,15,2)*(-3,3,7)=(-45,45,14)
