A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a 50-50 chance of

getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for 80% of the successful bids and 35% of the unsuccessful bids the agency requested additional information. a. What is the prior probability of the bid being successful (that is, prior to the request for additional information)

Answer:

Probability = 0.50

Step-by-step explanation:

Given

Probability = 50\ 50\ chance  

Successful\ Bids = 80\%

Unsuccessful\ Bids = 35\%

Required

Determine the probability before the request of past experience

In this case, we only consider the 50 50 chance probability

Probability = \frac{50}{50 + 50}

Probability = \frac{50}{100}

Probability = 0.50

Six times a number, increased by 3 is is 27. find the number
Mekhanik [1.2K]

Answer : The number is 4.

Step-by-step explanation:

<u>Given : </u>

six times a number, increased by 3 is is 27.

<u>To Find: </u>

The number.

<u>Solution : </u>

Let the number is x

six times a number is 6x

Increased by 3 = 6x+3

According to the given question :

<u>Solving the value x : </u>

6x+3 =27

6x = 27-3

6x = 24

x = 24/6

x = 4

Answer:

x = 12

Step-by-step explanation:

The shape ABCDEF is an irregular polygon.  

The sum of the interior angles of any regular or irregular polygon = (n - 2) x 180 (where n is the number of sides of the polygon).  

Therefore, the sum of the interior angles of shape ABCDEF = (6 - 2) x 180 = 720°

So to find the value of x, we need to add together all the interior angles and equal it to 720, then solve for x.

Before we do that, we need to determine angle F.

From inspection, we can see that angle F and 52° are a linear pair.  We know that a linear pair of angles add up to 180°, so F + 52 = 180  ⇒  F = 180 - 52 = 128°

Therefore:

                                           A + B + C + D + E + F = 720

(10x - 5) + 108 + (8x - 3) + (14x - 25) + 133 + 128 = 720

Collect like terms:

10x + 8x + 14x - 5 + 108 - 3 - 25 + 133 + 128 = 720

Combine like terms:

32x + 336 = 720

Subtract 336 from both sides:

32x = 384

Divide both sides by 32:

x = 12

Solve the quadratic equation x2=25/36.<br><br><br>What are the solutions of the equation x2=25/36?
Alinara [238K]

Answer:

x is equal to positive 5/6 and negative 5/6

Step-by-step explanation:

To solve this, you simply need to take the square root of both sides:

x^2 = \frac{25}{36}\\\sqrt{x^2} = \sqrt{\frac{25}{36}}\\x = \pm \frac{5}{6}
