help mePsychologists striving to understand the human mind may study the nervous system. Learning how the cells and organs (like the brain) function, help us understand the biological basis behind human psychology. The nervous system is composed of two basic cell types: glial cells (also known as glia) and neurons. Glial cells, which outnumber neurons ten to one, are traditionally thought to play a supportive role to neurons, both physically and metabolically. Glial cells provide scaffolding on which the nervous system is built, help neurons line up closely with each other to allow neuronal communication, provide insulation to neurons, transport nutrients and waste products, and mediate immune responses. Neurons, on the other hand, serve as interconnected information processors that are essential for all of the tasks of the nervous system. This section briefly describes the structure and function of neurons.

Which statement best evaluates the effectiveness of the conclusion
paragraph?
Thesis Statement: My future job must include human interaction, a
nontraditional workspace, and teamwork.
Main Points:
1. Work with people
2. Work in a nontraditional workspace
3. Work in a place where coworkers share ideas
Conclusion: In the end, my future job will be one that allows me to
collaborate with my coworkers in dynamic and nontraditional
workspaces. If I am forced to sit behind a desk I will be extremely bored. Furthermore, I will be less productive if I am forced to work alone without the chance to discuss ideas with my coworkers. So the next time an adult asks me what I want to do when
I grow up, I will tell them a job without a desk, in an office full of
people. That's my dream job!
A. The conclusion is effective because it presents interesting information not addressed in the body paragraphs.
B. The conclusion is ineffective because it does not restate the thesis in a new way.
C. The conclusion is effective because it restates the thesis, summarizes the main points, and includes a satisfying close.
D. The conclusion is ineffective because it fails to leave the reader with a thought-provoking question.Which statement best evaluates the effectiveness of the conclusion paragraph?

Answer: 1/32
Step-by-step explanation:
Instructions: Find the missing side. Round your answer to the nearest tenth.
Answer:
x = 24.9
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos 43 = x /34
34 cos 43 = x
x=24.86602
To the nearest tenth
x = 24.9
Solve Q²= a(p²-b²)/p in form of y=mx+c
Answer:
We want to rewrite:
q^2 = a*(p^2 - b^2)/p
as a linear equation, in the form:
y = m*x + c
So we start with:
q^2 = a*(p^2 - b^2)/p
we can expand the left side to get:
q^2 = (a/p)*p^2 - (a/p)*b^2
q^2 = a*p - (a/p)*b^2
Now we can ust define:
a*p = c
Then we can replace that to get:
q^2 = -(a/p)*b^2 + c
now we can replace:
q^2 = y
b^2 = x
Replacing these, we get:
y = -(a/p)*x + c
finally, we can replace:
-(a/p) = m
then we got the equation:
y = m*x + c
where:
y = q^2
x = b^2
c = a*p
m = -(a/p)
Solve the following inequality: |2x|<14 A. 7
Answer:
x<7
Step-by-step explanation:
it just is
Answer:
x > 7
x < -7
Step-by-step explanation:
Absolute value inequalitiy entered
|2x| > 14
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |2x|
For the Negative case we'll use -(2x)
For the Positive case we'll use (2x)
-(2x) > 14
Multiply
-2x > 14
Divide both sides by 2
-x > 7
Multiply both sides by (-1)
Remember to flip the inequality sign
x < -7
Which is the solution for the Negative Case
(2x) > 14
Divide both sides by 2
x > 7
Which is the solution for the Positive Case
x < -7
x > 7

This is the answer.
The t distribution should be used whenever _____. Group of answer choices the sample size is less than 30 the population is not normally distributed the sample standard deviation is used to estimate the population standard deviation None of the answers is correct.
Answer:
A: the sample size is less than 30
Step-by-step explanation:
Usually, the t-distribution is used instead of normal distribution in calculation of the mean of a normally distributed population when the sample size is small (n < 30) and if the population standard deviation is not known.
Thus, looking at the options, the correct one is Option A.

find the measure of the indicated angle to the nearest degree
Answer:
[tex]20^{\circ}[/tex]
Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse.
Let the angle we want to find be [tex]\theta[/tex]. [tex]\theta[/tex]'s adjacent side is 49 and the hypotenuse of the triangle is 52.
Therefore, we have the equation:
[tex]\cos \theta=\frac{49}{52}[/tex]
Take the inverse cosine of both sides:
[tex]\arccos (\cos \theta)=\arccos(\frac{49}{52})[/tex]
Simplify using [tex]\arccos (\cos \theta)=\theta \text{ for }\theta \in (0, 180^{\circ})[/tex]:
[tex]\theta=\arccos(\frac{49}{52}),\\\theta=19.557214,\\\theta\approx \boxed{20^{\circ}}[/tex]

For the transition matrix P = [0.8 2 0.2 2, 0.3 0.7], solve the equation SP = S to find the stationary matrix S and the limiting matrix Upper P overbar.
Answer:
Stationary matrix S = [ 0.6 0.4 ]
limiting matrix P = [tex]\left[\begin{array}{ccc}0.6&0.4\\0.6&0.4\\\end{array}\right][/tex]
Step-by-step explanation:
Transition matrix
[tex]p = \left[\begin{array}{ccc}0.8&0.2\\0.3&0.7\\\end{array}\right][/tex]
solving the equation SP = S ( using Markova chain with 2 states )
stationary matrix, S = [ a , 1 - a ]
given that SP = S
[ a , 1 - a ] * [tex]\left[\begin{array}{ccc}0.8&0.2\\0.3&0.7\\\end{array}\right][/tex] = [ a , 1 - a ]
= a*(0.8) + ( 1 - a ) ( 0.3 ) = a
∴ a = 0.6
hence; stationary matrix S = [ 0.6 0.4 ]
limiting matrix P = [tex]\left[\begin{array}{ccc}0.6&0.4\\0.6&0.4\\\end{array}\right][/tex]

The 12th term of the arithmetic sequence is 10.5. The 18th term of this sequence is 13.5. Find the common difference and the first term.
Answer:
Common difference = 0.5
First term = 6.
Step-by-step explanation:
the 12th term a12 = a1 + d(12-1) where a1 = first term and d = the common difference.
So a1 + 11d = 10.5 ....(A) Similarly:
a1 + 17d = 13.5....(B)
Subtracting equations:
(B) - (A) :-
6d = 13.5 - 10.5 = 3
d = 3/6 = 0.5
From equation (A):
a1 + 11(0.5) = 10.5
a1 = 10.5 -5.5 = 5.
