The concept of discontinuity is characterized by qualitative change.

Answer: Option D

Explanation:

There are certain changes in processes initiated that can tend a specific process to discontinue and continue in a new form or otherwise totally cease.

These changes usually occur due to differences in the sequence of stages of the process, difference in quality, or due to a distinct change. Thus, discontinuity can be regarded as the discontinuity of a specific part of the process or the discontinuity of the entire process.

Effectus [21]

Answer:

The correct answer is: Cerebellum

Explanation:

Cerebellum is a part of the hindbrain and is found in the posterior cranial fossa in the cranial cavity.

This part of the brain receives inputs from the spinal cord and the brain and thus plays a crucial role in motor control. It is associated with timing, coordination, and precision.

It is also involved in the regulation of fear and pleasure responses, attention and language.

Since in the given example, after the accident Tracey is experiencing difficulty in coordination. Therefore, she has most likely damaged the Cerebellum.

In-s [12.5K]

Answer:

$z=1.28$

And if we solve for a we got

$a=58 +1.28*5=64.4$

So the value of height that separates the bottom 90% of data from the top 10% is 64.4.

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 velocity of a population, and for this case we know the distribution for X is given by:

$X \sim N(58,5)$

Where $\mu=58$ and $\sigma=5$

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.10$ (a)

$P(X$ (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.

As we can see on the figure attached the z value that satisfy the condition with 0.90 of the area on the left and 0.1 of the area on the right it's z=1.28. On this case P(Z<1.28)=0.9 and P(z>1.28)=0.1

If we use condition (b) from previous we have this:

$P(X$

$P(z$

But we know which value of z satisfy the previous equation so then we can do this:

$z=1.28$

And if we solve for a we got

$a=58 +1.28*5=64.4$

So the value of height that separates the bottom 90% of data from the top 10% is 64.4.

boyakko [2]

Answer:

Students who watch more television perform more poorly on their exams.

Explanation:

Television can be very detrimental to students' academic performance. There needs to be a balance between the amount of time a student is watching and the amount of time he is studying, doing physical and academic activities, and sleeping.

The more time the student spends assuming the less time he will have for other activities. With this, the activities of academic nature will be impaired, the student will not give enough attention to the studies and with that the academic performance of this student will fall.

From this we can conclude that students who watch more television perform worse on exams.
