Answer: Isosceles

<u>Step-by-step explanation:</u>

Given: AB || DE ,  BC is a transversal

∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°

∠DCA, ∠ACB, & ∠BCA are supplementary  --> ∠ACB = 50°

By the Triangle Sum Theorem, ∠A+∠B+∠C  = 180° --> ∠CAB = 50°

Triangle is isosceles because ∠A ≅ ∠C

A major television manufacturer has determined that its 44 inch screens have a mean service life that can be modeled by a normal
Neko [114]

Answer:

P(5

And we can find this probability with thie difference:

P(-2

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

X \sim N(6,0.5)  

Where \mu=6 and \sigma=0.5

We are interested on this probability

P(5

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(5

And we can find this probability with thie difference:

P(-2

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2
