Step-by-step explanation:

–2(5 – 4x) < 6x – 4

Step 1: –10 + 8x < 6x – 4

Step 2: –10 < –2x – 4

Step 3: –6 < –2x

Step 4: divide each side by by -2, remembering to flip the inequality

Hello!

For #1, the LCD is (A) 12 since both numbers go into 12 as their minimal number.

For #2, the missing number is (B) 4 because 1/4*4/4=4/16.

For #3, the answer is (B) 3 because you have to crossmultiply 20n(4*15) to find the answer.

for #4, the correct answer is (A) 4/5 is less than 5/6 because when converted into fractions with a common denominator, 24/30 is less than 25/30.

For #5, the LCD is 36; therefore, the answer is (A) because the fractions in the answer are properly converted to their new denominator.

I really hope I helped!

Marizza181 [45]

Answer:

(a) 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent.

Step-by-step explanation:

We are given that a certain federal agency employs three consulting firms (A, B and C) with probabilities 0.4, 0.35 and 0.25 respectively i.e.;

 P(A) = 0.4        P(B) = 0.35          P(C) = 0.25

Also, From past experience it is known that the probability of cost overruns for the firms are 0.05, 0.03, and 0.15, respectively which means;

Let CO = Event of cost overruns

P(CO/A) = 0.05 - It means probability of cost overruns given the consulting firm involved was A.

Similarly, P(CO/B) = 0.03      P(CO/C) = 0.15

(a) Probability that the consulting firm involved is company A given a cost overrun is experienced by the company is given by, P(A/CO);

We will use Bayes' theorem here calculating the above probability ;

           P(A/CO) = \frac{P(A)*P(CO/A)}{P(A)*P(CO/A) + P(B)*P(CO/B) + P(C)*P(CO/C)}

                          = \frac{0.4*0.05}{0.4*0.05 + 0.35*0.03 + 0.25*0.15} = 0.29412 .

(b) No, the events selecting company A and incurring in cost overruns are not independent because the cost overruns happens only when the consulting firm is involved and also the cost overruns will differ as we move towards another consulting firm so the chances of cost overruns will depend on the fact that which consulting firm has been involved.
