A consulting firm submitted a bid for a large research project. The firm’s management
amid [387]

Answer:

(a) 0.50

(b) 0.75

(c) 0.6522

Step-by-step explanation:

We are given that the firm’s management  initially had a 50–50 chance of getting the project.

Let Probability of getting a project or bid being successful, P(S) = 0.50

Probability of not getting a project or bid being unsuccessful, P(US) = 1 - 0.50 = 0.50

Also, Past  experience indicates that for 75% of the successful bids and 40% of the unsuccessful bids  the agency requested additional information which means;

Let event R = agency requested additional information

So, Probability that the agency requested additional information given the bid was successful, P(R/S) = 0.75

Probability that the agency requested additional information given the bid was unsuccessful, P(R/US) = 0.40

(a) Prior probability of the bid being successful = Probability of getting a project or bid being successful = \frac{50}{100} = 0.50

(b) The conditional probability of a request for additional information given that  the bid will ultimately be successful = P(R/S) = 0.75

(c) The posterior probability that the bid will be successful given a request for  additional information is given by P(S/R) ;

Using Bayes' Theorem for this we get;

   P(S/R) = \frac{P(S) * P(R/S)}{P(S)*P(R/S) + P(US) * P(R/US)} = \frac{0.50 * 0.75}{0.50*0.75 + 0.50*0.40} = 0.6522 .

The circumference of a planet is about 23,000 miles. Find its diameter to the nearest mile.
lakkis [162]
Circumference = \pi d

We know that the circumference in here is equal to 23000 miles. 

23000 = pi x d 

pi will be approximated to 3.14 

23000 = 3.14d 

divide both sides by 3.14 to get 
about 7325 as the diameter

Solve for the expression. 3 1/5x3/5
zloy xaker [14]

Answer:

1 23/25

Step-by-step explanation:

3 1/5 * 3/5

Change the mixed number to an improper fraction

(5*3+1 )/5 = 16/5

16/5 * 3/5 = 48/25

Change to a mixed number

25/25 + 23/25

1 23/25

The order of temperature values become -16.7°C > -11.15°C > -7°C > 3°C And -16.7°C is the coolest temperature and 3°C is the warmest as compare to others.

According to the statement

we have given that the some values of the temperatures and we have to write it in the order from the coolest to the warmest means in increasing order.

So, For this purpose,

The given values of temperatures are:

3°C , -7°C , 2°F, 262 K

Firstly convert into one form

So, convert all values in Celsius form,

3°C = 3°C

-7°C = -7°C

2°F = -16.7°C

262 K = -11.15°C

Now arrange into the order from coolest to warmest

So, it will become

-16.7°C > -11.15°C > -7°C > 3°C

So, -16.7°C is the coolest temperature and 3°C is the warmest as compare to others.

The order of temperature values become -16.7°C > -11.15°C > -7°C > 3°C And -16.7°C is the coolest temperature and 3°C is the warmest as compare to others.
