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

A box contains 1079 counters which are coloured either black, white or red.
aleksley [76]

<u><em>The total number of red counters that are in the box is; 728 red counters</em></u>

  • We are told that the box contains 1079 counters.

Let the number of white counters be x.

Let the number of red counters be y.

Let the number of black counters be z.

Thus;

z:x = 2:7

Thus; 2x/7 = z

Also, we are given;

x:y = 3:8

Thus;

8x/3 = y

  • Since total number in the box is 1079,then;

x + y + z = 1079

x + (8x/3) + (2x/7) = 1079

Multiply through by 21 to get;

21x + 56x + 6x = 22659

83x = 22659

x = 22659/83

x = 273

2x/7 = z

Thus; z = 2 × 273/7

z = 78

8x/3 = y

y = 8 × 273/3

y = 728

  • Thus,there are;

273 white counters

728 red counters

78 black counters.

if -16 is added to a numbet and the sum is doubled, the result is 17 less than the number. what is the number?
ololo11 [35]

Our missing number we are solving for is X.

We are told x will equal 2x (number doubled) plus -16.

x = 2x + -16 We want to move the smaller variable to the right to sit with the larger one and move the -16 to the left by subtracting it from both sides. Remember that subtracting a negative is the same as adding it. So essentially we add 16 to both sides.

16 = 2x - x Combine the variables

16 = x or x = 16

I chose to put the variable on the left in this problem to avoid having a -x on the left side. It doesn't matter which side the variable is on to solve, but when you state it - we usually say x = 16.

Points!! Help PLEASE!!!!!!!!!!!!!!!!! I've been stumped forever!:( Point estimate? Poll's margin of error? Fill in the blanks:
Brut [27]
The point estimate is the mid-point of the interval:
\frac{.35+.43}{2} = \frac{.78}{2} = 0.39

The margin of error is the difference between the endpoints of the interval and the mid-point.
0.43 - 0.39 = 0.04 = 4\%

Adam has four short straws, five medium straws, and six long straws. If he randomly draws two straws, one at a time without repl
Softa [21]

Answer:

5/15 or 3rd Chance.

Step-by-step explanation: If you add all of the straws together, and take the amount of medium straws there are: the probability will be limited to the amount of medium straws - of course with the total amount involved. Though, I'm not entirely sure, It's been a while since I've done anything like that.
