Answer:

Yes

Step-by-step explanation:

The answer is yes because none of the x-coordinates repeat. If one or more of the x-coordinates repeat, it is no longer considered a function.

For several hours you watch a group playing dice on the street and you notice that the owner of the dice often wins.
Nostrana [21]

Answer:

there is no question

Step-by-step explanation:

It looks like the owner plays dirty, meaning he uses a trick of some kind to somehow influence the outcome in such a way, that it's outcome is no longer random.

By influencing the outcome, the owner can obtain an advantage over the playeers who are not aware of the trick or skill involved.

This is unfair and can be considered "dirty". This game is 'fixed'.

zavuch27 [327]

Answer:

The bottom surface of the glass container will be covered a quarter of the way on March 8th.

Step-by-step explanation:

The bacteria covering the bottom surface of the glass container doubles every day. If the surface is completely covered on March 10th, then one day earlier, on March 9th, half of the surface is covered.

Similarly, if half of the surface is covered on March 9th, then one day earlier, on March 8th, a quarter of the surface is covered.

Therefore, the bottom surface of the glass container will be covered a quarter of the way on March 8th.

A random sample of size 100 is taken from a population with the mean as 76 and the variance as 256. what is probability of getti
Blababa [14]

Given the population mean is \mu=76 and population standard deviation is \sigma=\sqrt{256} =16.

Now sample mean is \mu_X=76 and standard deviation of the sample mean is \sigma_X=\frac{\sigma}{\sqrt{n}} =\frac{16}{\sqrt{100}}=1.6.

Use Z-score for finding the probabilities. Use a standard normal distribution table.

a)The probability

P(74.4

b)The probability

P(X

c)The probability

P(X>78.4)=P(Z>\frac{78.4-76}{1.6}) \\  P(X>78.4)=P(Z>1.5) \\ P(X>78.4)=0.0668
