Y=78
A polygon has a total of 5 interior angles
In order to find the total amount of angles in a shape you do (the amount of angles - 2)x180 degrees
(5-2(3))180
3x180=540
Add the numbers you know (10+20+30+40+50=150)
540-150=390 and there are 5y altogether so divide 390 by 5 which is 78

(2.5 points) The probability that an airplane accident which is due to structural failure is diagnosed correctly is 0.85 and the
Nikitich [7]

Answer: 0.51

Step-by-step explanation:

This is a conditional probability. The first event is the airplane accident being caused by structural failure. The probability of it being due to structural failure is 0.3 and the probability of it not being due to structural failure is 0.7. The second event involves the diagnosis of the event. If a plane fails due to structural failure, the probability that it will be diagnosed and the results will say it was due to structural failure is 0.85, and the probability that the diagnosis is unable to identify that it was because of a structural failure is 0.15. If the plane were to fail as a result of some other reason aside structural failure, the probability that the diagnosis will show that it was as a result of structural failure is 0.35 and the probability of the diagnosis showing that is is not as a result of structural failure is 0.65. To find the probability that an airplane failed due to structural failure given that it was diagnosed that it failed due to some malfunction, this is the equation;

p = (probability of plane failing and diagnosis reporting that the failure was due to structural failure)/ (probability of diagnosis reporting that failure was due to structural failure)

p = (0.3*0.85)/((0.3*0.85) + (0.7*0.35))

p = 0.51

mamaluj [8]

Answer:

It is an unusual result contradicting the national survey.

Step-by-step explanation:

National survey showed 44% of college students who drink.

The professor's survey showed that 96/244 = 39% drink.

The professor's survey deviated from the national survey is 5% (44% - 39%) representing about 0.25% (5% squared) variance.

Standard deviation is the spread of a set of numbers from their mean.  In other words, it measures how far an observed value is from the mean. It can be calculated by getting the square root of the variance.

Katyanochek1 [597]

Answer:

  • A = 0.85(b +47)
  • $143.65

Step-by-step explanation:

Since the number of bagels sold already is 47, the total number of bagels sold will be b+47. The revenue from each sale is $0.85, so the total revenue will be ...

  A = 0.85·(b +47)

This equation can be written in different forms, but this satisfies the requirement for "an equation."

__

Since b is the number of addition bagels, when 122 additional bagels are sold, the value of b is 122. Then the equation becomes ...

  A = 0.85·(122 +47)

  A = 0.85·169 = 143.65

Revenue will be $143.65 when 122 additional bagels are sold.
