For this case we can define the random variable of interest as: "The nicotine content in a single cigarette " and for this case we know the following parameters:

$\mu = 0.4, \sigma = 0.1$

And for this case we select a sample size of n =100 and we want to find the following probability:

$P(\bar X$

And for this case we can use the z score formula given by:

$z =\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z= \frac{0.38-0.4}{\frac{0.1}{\sqrt{100}}}= -2$

And we can find the required probability with the normal standard table and we got:

$P(z$

What happens if the red lines are NOT parallel. Which angle types are still congruent?(please help)

PtichkaEL [24]

Answer:

If they are not parallel they will cross.

The angle types that are still congruent are the angles that are the same size.

Step-by-step explanation:

Parallel lines never cross but non parallel lines cross.
