Hoping to increase the chances of reaching a performance goal, the director of a research project has assigned three separate re

search teams the same task. the director estimates that the team probabilities are .9, .8, and .7 for successfully completing the task in the allotted time. assuming that the teams work independently, what is the probability that the task will not be completed in time?

Here, the probabilities for success for the three teams are 0.9, 0.8 and 0.7, so the probability of failure for the three teams will be 0.1, 0.2 and 0.3.

We need to find the probability that all the teams fail, which can be calculated as: 0.1 * 0.2 * 0.3 = 0.0060 or 0.60%.

I hope my solution solves your query.

Currently, you owe the bank $9,800 for a car loan. The loan has an interest rate of 7.75 percent and monthly payments of $310. Y
Ostrovityanka [42]

Answer:

It will extend the loan for 15.83 months = 16 more months.

Explanation:

We need to calcualte the difference in time between one option and another:

Original Loan:

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C  $310.00

time n

rate 0.0064583 (0.0775annual rate / 12 month per year)

PV $9,800

310 \times \frac{1-(1+0.0064583)^{-n} }{0.0064583} = 9800\\

We rearrenge and solve as much as we can:

(1+0.0064583)^{-n}= 1-\frac{9800\times0.0064583}{310}

(1+0.0064583)^{-n} = 0.79583439

Now, we solve using logarithmics properties:

-n= \frac{log0.795834387096774}{log(1+0.0064583)}

35.47385568

Now we calcualte with the new terms:

C  $225.00

225 \times \frac{1-(1+0.0064583)^{-n} }{0.0064583} = 9800\\

(1+0.0064583)^{-n}= 1-\frac{9800\times0.0064583}{225}

(1+0.0064583)^{-n}= 0.71870516

-n= \frac{log0.718705155555555}{log(1+0.0064583)}

51.30909653

Last step, we solve for the difference:

51.30 - 35.47 = 15.83 = 16 more months

Mercury Company sells tickets in advance for its weekly productions and records the proceeds as Unearned Revenue. At the end of
sattari [20]

Answer:I did the calculations and i believe i got it right.

Explanation:

Mercury sold 500 tickets at $40 a piece, okay, still with me, good. Yet, only 450 tickets were used during the month. What that mean is to minus 50 tickets. 50 multiplied by $40 is $2000. 500 multiplied by $40 equals to $20000. $20000 minus $2000 is equaled to $18000. They also had a Unearned Revenue account that had a credit balance of $5000. So, that means they should be in "debt." They should have $-15000. Add $2000, it is equaled to $-13000. So it should be $-13000. If wrong, i'm sorry.
