PLEASEE HELP ASAP I REALLY NEED HELP

Mathematics
1 answer:
AURORKA [14]3 years ago
7 0

Answer:

1) y = 115°

2) x = 120°

3) x = 163°

Step-by-step explanation:

  • the sum of the interior angles of a figure = (number of sides - 2) * 180

1)

the sum of the interior angles of this figure = (5 - 2) * 180 = 540°

the fifth angle = the sum of the interior angles - the sum of the four angles

the fifth angle or y = 540 - (90 + 135 + 112 + 88) = 115

2)

the sum of the interior angles = (6 - 2) * 180 = 720°

x = 720 - (90 + 90 + 140 + 150 + 130) = 120

3)

the sum of the interior angles = (5 - 2) * 180 = 540°

x = 540 - (68 + 121 + 103 + 85) = 163

Let x denote the lifetime of a mcchine component with an exponential distribution. The mean time for the component failure is 25
aliina [53]

Answer:

0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

The probability that x is lower or equal to a is given by:

P(X \leq x) = \int\limits^a_0 {f(x)} \, dx

Which has the following solution:

P(X \leq x) = 1 - e^{-\mu x}

The probability of finding a value higher than x is:

P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}

The mean time for the component failure is 2500 hours.

This means that m = \frac{2500}, \mu = \frac{1}{2500} = 0.0004

What is the probability that the lifetime exceeds the mean time by more than 1 standard deviations?

The standard deviation of the exponential distribution is the same as the mean, so this is P(X > 5000).

P(X > x) = e^{-0.0004*5000} = 0.1353

0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations
