Step-by-step explanation:
Transversal
A line that crosses two other lines in the same plane at two distinct points.
Corresponding angles
A pair of angles that are in the same position relative to both lines crossed by the transversal.
Alternate interior angles
A pair of angles on the inner side of the two lines that the transversal crosses, but on opposite sides of the transversal.
Alternate exterior angles
A pair of angles on the outer side of the two lines that the transversal crosses, but on opposite sides of the transversal.
Consecutive interior angles
A pair of angles on the inner side of the two lines that the transversal crosses, and are on the same side of the transversal.
a) Lines p and q are crossed by transversal line s.
Therefore, ∠4 and ∠7 are consecutive interior angles as they are on the inner side of lines p and q, and are on the same side of the transversal s.
b) Lines r and s are crossed by transversal line p.
Therefore, ∠2 and ∠11 are alternate exterior angles as they are on the outer side of lines r and s, but on opposite sides of the transversal p.
c) Lines p and q are crossed by transversal line s.
Therefore, ∠12 and ∠16 are corresponding angles as they are in the same position relative to lines p and q crossed by the transversal s.
d) Lines r and s are crossed by transversal line q.
Therefore, ∠8 and ∠13 are alternate interior angles as they are on the inner side of lines r and s, but on opposite sides of the transversal q.
e) Lines p and q are crossed by transversal line s.
Therefore, ∠11 and ∠15 are corresponding angles as they are in the same position relative to lines p and q crossed by the transversal s.
f) ∠7 and ∠10 have no relationship.
g) Lines p and q are crossed by transversal line r.
Therefore, ∠1 and ∠14 are alternate exterior angles as they are on the outer side of lines p and q, but on opposite sides of the transversal r.
h) Lines p and q are crossed by transversal line s.
Therefore, ∠12 and ∠15 are consecutive interior angles as they are on the inner side of lines p and q, and are on the same side of the transversal s.
i) ∠6 and ∠7 have no relationship
j) Lines r and s are crossed by transversal line p.
Therefore, ∠1 and ∠3 are corresponding angles as they are in the same position relative to lines r and s crossed by the transversal p.
k) Lines r and s are crossed by transversal line q.
Therefore, ∠14 and ∠16 are corresponding angles as they are in the same position relative to lines r and s crossed by the transversal q.
l) Lines r and s are crossed by transversal line q.
Therefore, ∠6 and ∠15 are alternate exterior angles as they are on the outer side of lines r and s, but on opposite sides of the transversal q.
m) Lines p and q are crossed by transversal line r
Therefore, ∠5 and ∠10 are alternate interior angles as they are on the inner side of lines p and q, but on opposite sides of the transversal r.
n) Lines r and s are crossed by transversal line q.
Therefore, ∠8 and ∠14 are consecutive interior angles as they are on the inner side of lines r and s, and are on the same side of the transversal q.

Find sin x/2, cos x/2, tan x/2. from the given information. tan x = [tex]\sqrt{2}[/tex]. 0° < x < 90°
The trigonometric measures for the given angle are as follows:
[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{6}}[/tex][tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 + \sqrt{3}}{6}}[/tex][tex]\tan{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{3 + \sqrt{3}}}[/tex]How to obtain the trigonometric measures?We are given the measure of the sine for the angle and we need to find the three measures, sine, cosine and tangent for half the angle.
These measures are dependent on the cosine of the function, hence we apply the definition of the tangent as follows:
[tex]\tan{x} = \frac{\sin{x}}{\cos{x}}[/tex]
Hence:
[tex]\sqrt{2} = \frac{\sin{x}}{\cos{x}}[/tex]
[tex]\sin{x} = \sqrt{2}\cos{x}[/tex]
The exact value of the cosine can be found applying the identity as follows:
sin²(x) + cos²(x) = 1.
Then, from the equation of the sine as a function of the cosine from the tangent relation, we have that:
[tex](\sqrt{2}\cos{x})^2 + \cos^2{x} = 1[/tex]
[tex]2^\cos^2{x} + \cos^2{x} = 1[/tex]
[tex]\cos^2{x} = \frac{1}{3}[/tex]
[tex]\cos{x} = \pm \sqrt{\frac{1}{3}}[/tex]
The angle is of the first quadrant, as 0° < x < 90°, hence the cosine is positive, thus:
[tex]\cos{x} = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}[/tex]
The identity that gives the sine for half the angle is:
[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 - \cos{x}}{2}}[/tex]
Hence:
[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 - \frac{\sqrt{3}}{3}}{2}}[/tex]
[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{6}}[/tex]
The identity for the cosine is almost the same, just there is a plus instead of a minus, hence:
[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 + \cos{x}}{2}}[/tex]
[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 + \frac{\sqrt{3}}{3}}{2}}[/tex]
[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 + \sqrt{3}}{6}}[/tex]
The tangent is the sine divided by the cosine, hence the inserting the entire division and the same square root and simplify the common denominator, thus:
[tex]\tan{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{3 + \sqrt{3}}}[/tex]

c. Comparing your answers from parts a and b, how
does the variability of the scores in the sample
influence the measures of effect size?
Through reporting statistical results, we found that [tex]r^{2}[/tex] is 0.22 and Cohen's [tex]d[/tex] is 0.52 when s = 8, and [tex]r^{2}[/tex] is 0.04 and Cohen's [tex]d[/tex] is 0.21 when s = 20. It is also observed that when the variability of the scores in the sample, [tex]r^{2}[/tex] decreases, there is simultaneous decrease in the measures of effect size, Cohen's [tex]d[/tex] as well.
It is given to us that -
A random sample of n = 16 scores
Population with a mean of μ = 45
Sample mean is found to be M = 49.2
In Reporting Statistical results, there are two different effect sizes, namely eta-squared [tex]r^{2}[/tex] and Cohen's [tex]d[/tex].
Eta-square, [tex]r^{2} = \frac{t^{2} }{t^{2}+df }[/tex]
where, [tex]df = n-1[/tex]
[tex]SEM = \frac{s}{\sqrt{n} }[/tex]
and, [tex]t=\frac{x_{2} -x_{1} }{SEM}[/tex]
Cohen's [tex]d=\frac{x_{2} -x_{1} }{s}[/tex]
a) Given that the sample standard deviation is s=8
We have n = 16
So, [tex]df = n-1 = 16-1 = 15[/tex]
[tex]SEM = \frac{s}{\sqrt{n} } = \frac{8}{\sqrt{16} } = \frac{8}{4} = 2[/tex]
We also have μ = 45 and M = 49.2. This implies
[tex]t=\frac{x_{2} -x_{1} }{SEM} = \frac{49.2-45}{2} = \frac{4.2}{2} =2.1[/tex]
Now,
[tex]r^{2} = \frac{t^{2} }{t^{2}+df } = \frac{(2.1)^{2} }{(2.1)^{2}+ 15 }= \frac{4.41}{4.41+15} \\= \frac{4.41}{19.41} = 0.22[/tex]
Cohen's [tex]d=\frac{x_{2} -x_{1} }{s} = \frac{49.2-45}{8} = \frac{4.2}{8} = 0.52[/tex]
b) Given that the sample standard deviation is s=20
We have n = 16
So, [tex]df = n-1 = 16-1 = 15[/tex]
[tex]SEM = \frac{s}{\sqrt{n} } = \frac{20}{\sqrt{16} } = \frac{20}{4} = 5[/tex]
We also have μ = 45 and M = 49.2. This implies
[tex]t=\frac{x_{2} -x_{1} }{SEM} = \frac{49.2-45}{5} = \frac{4.2}{5} =0.84[/tex]
Now,
[tex]r^{2} = \frac{t^{2} }{t^{2}+df } = \frac{(0.84)^{2} }{(0.84)^{2}+ 15 }= \frac{0.706}{0.706+15} \\= \frac{0.706}{15.706} = 0.04[/tex]
Cohen's [tex]d=\frac{x_{2} -x_{1} }{s} = \frac{49.2-45}{20} = \frac{4.2}{20} = 0.21[/tex]
c) Comparing a and b, we see that the variability of the scores in the sample, [tex]r^{2}[/tex] is 0.22 when s = 8 and [tex]r^{2}[/tex] is 0.04 when s = 20. Similarly, Cohen's [tex]d[/tex] is 0.52 when s = 8 and [tex]d[/tex] is 0.21 when s = 20.
Thus, we can see that when the variability of the scores in the sample, [tex]r^{2}[/tex] decreases, there is simultaneous decrease in the measures of effect size, Cohen's [tex]d[/tex] as well.

There are two high schools in a small town.
High school A has currently 900 students and is projects to grow by 30 students each year
Similarly
High school B has currently 750 students and is projected to grow by 45 students each year.
To find the equation for each situation in terms of t years.
also in how many years t' the number of students in both high schools would be same?
Given
The initial strength of school A = 900
the increasing rate of students = 30 students per year
i.e students in 1 year = 30
students in t years = 30t
Total students of school A after 't' years = 900+ 30t
⇒ A = 600+ 65t
The initial strength of school B = 750
increasing rate of students = 45 per year
i.e. student in 1 year = 45
⇒ student in 't' years = 45t
Total students of school B in 't' years = 950 + 30t
=> B=950+30t
Now to find no. of years 't' when students in both schools are the same i.e. A =B
⇒ 900+ 30t = 750 + 45t
⇒ 45t-30t = 900-750
⇒ 15t = 150
⇒t= 150 /15
⇒t=10
Therefore after 10 years, students in both schools are the same.

A chemical company makes two brands of antifreeze. The first brand is 70% pure antifreeze, and the second brand is 95% pure antifreeze. In order to obtain 170 gallons of a mixture that contains 80% pure antifreeze, how many gallons of each brand of antifreeze must be used?
first brand: ?
Second brand ?
please dont answer if you dont know it.
The quantity of first brand is 102 gallons and quantity of second brand is 68 gallons
Given,
The first brand of antifreeze = 70% pure antifreeze
The second brand of antifreeze = 95% pure antifreeze
The quantity of mixture = 170 gallons contains 80% pure antifreeze
We have to find the quantity of each brand of antifreeze must be used;
Now,
The quantity of first brand = x gallons
The quantity of second brand = y gallons
Then,
x + y = 170
x = 170 - y ....(1)
70x / 100 + 95y / 100 = (80 × 170) / 100
70x + 95y = 13600
Now, putting the value of x from equation 1:
70 (170 - y) + 95y = 13600
11900 - 70y + 95y = 13600
11900 + 25y = 13600
25y = 13600 - 11900
25y = 1700
y = 1700/25
y = 68
Now, putting this value of y in equation 1:
x = 170 - 68
x = 102
Therefore,
The quantity of first brand is 102 gallons and quantity of second brand is 68 gallons
