The correct answer is B C and D
Hello!
1) PEMDAS. Almost any expression ever
2) A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
3) 8.38889 yards
4) idk sorry :'(
5) X= 11
6) X = -5
7) 3(x + 5).
I hope it helps!
5*0.6=3
3*0.6=1.8
1.8*0.6=1.08
5+(3*2)+(1.8*2)+(1.08*2)=16.76 ft
Answer:
1 yard
Step-by-step explanation:
Let b represent the amount of blue fabric and r represent the amount of red fabric.
Given;
Jessi has 9 feet of blue fabric
b = 9 ft
She need one third of that amount in red fabric.
r = 1/3 × b
Substituting the value of b;
The amount of red fabric needed r is;
r = 1/3 × 9 = 3 ft
Since they sell in yards , we need to convert it to yards.
1 yard = 3 feets
Therefore,
r = 3 ft × 1/3 yard per ft
r = 1 yard
Answer:
a) 0.623 (62.3%)
b) 0.764 (76.4%)
c) 0.6 (60%)
Step-by-step explanation:
a) defining the event F= the product is favorable , then the probability is
P(F) = probability that the study was sponsored by food industry * probability that the product is favorable given that it was sponsored + probability that the study had no corporate ties * probability that the product is favorable given that it was not sponsored = 0.70 * 0.68 + 0.30 * 0.49 = 0.623
b) for conditional probability we use the theorem of Bayes , then defining the event S= the study was sponsored by the food industry , we have:
P(S/F)=P(S∩F)/P(F)= 0.70 * 0.68/0.623 = 0.764 (76.4%)
where
P(S∩F)=probability that the study was sponsored by food industry and the product was found favorable
P(S/F)=probability that the study was sponsored by food industry given that the product was found favorable
c) for U= the product was found unfavourable , doing the same procedure as in a)
P(U)= 0.70 * 0.10 + 0.30 * 0.35 = 0.175
and the corresponding conditional probability is
P(N/U)=P(N∩U)/P(U)= 0.30 * 0.35 / 0.175 = 0.6 (60%)
where N represents the event = the study had no industry funding
