I took the test and got 100% on it.
The solution is : x = 77 and x > 38.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
we know that,
Sum of all angles in a triangle is 180.
The angle PNO will hence be:
180 - 38 - 39 = 103 degrees.
The angle PNO + angle x = 180 degrees (straight line)
So 103 + x = 180,
therefore x = 180 - 103 = 77.
Which is also greater than 38,
so x > 38 is also correct.

A newsletter publisher believes that 64d% of their readers own a Rolls Royce. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.020.02 level of significance, the testing firm decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
Step-by-step explanation:
The null hypothesis
[tex]H_o:p=0.64[/tex]
The alternative hypothesis
[tex]H_1:p \neq 0.64[/tex]
At 0.02 level of significance,
the testing firm rejects the null hypothesis.
This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.

Find the distance between the point (-2, -3) and the line with the equation y=4-2/3x
Answer:
[tex]D = \frac{25\sqrt{13}}{13}[/tex]
Step-by-step explanation:
Given
[tex]y = 4 - \frac{2}{3}x[/tex]
[tex](x_1,y_1) = (-2,-3)[/tex]
Required
Determine the distance
[tex]y = 4 - \frac{2}{3}x[/tex]
Write the above equation in standard form:
[tex]Ax + By + C = 0[/tex]
So, we have:
[tex]\frac{2}{3}x+y - 4 = 0[/tex]
By comparison:
[tex]A = \frac{2}{3}[/tex] [tex]B = 1[/tex] and [tex]C = -4[/tex]
The distance is calculated using:
[tex]D = \frac{|Ax_1 + By_1 + C|}{\sqrt{A^2 + B^2}}[/tex]
Where:
[tex](x_1,y_1) = (-2,-3)[/tex]
[tex]A = \frac{2}{3}[/tex] [tex]B = 1[/tex] and [tex]C = -4[/tex]
This gives:
[tex]D = \frac{|\frac{2}{3} * (-2) + 1 * (-3) - 4|}{\sqrt{(\frac{2}{3})^2 + 1^2}}[/tex]
[tex]D = \frac{|-\frac{4}{3} -3 - 4|}{\sqrt{\frac{4}{9} + 1}}[/tex]
Take LCM
[tex]D = \frac{|\frac{-4-9-12}{3}|}{\sqrt{\frac{4+9}{9}}}[/tex]
[tex]D = \frac{|\frac{-25}{3}|}{\sqrt{\frac{13}{9}}}[/tex]
[tex]D = |\frac{-25}{3}|/\sqrt{\frac{13}{9}}[/tex]
[tex]D = \frac{25}{3}/\sqrt{\frac{13}{9}}[/tex]
Split the square root
[tex]D = \frac{25}{3}/\frac{\sqrt{13}}{\sqrt{9}}[/tex]
Change / to *
[tex]D = \frac{25}{3}*\frac{\sqrt{9}}{\sqrt{13}}[/tex]
[tex]D = \frac{25}{3}*\frac{3}{\sqrt{13}}[/tex]
[tex]D = \frac{25}{\sqrt{13}}[/tex]
Rationalize
[tex]D = \frac{25}{\sqrt{13}} * \frac{\sqrt{13}}{\sqrt{13}}[/tex]
[tex]D = \frac{25\sqrt{13}}{13}[/tex]
Hence, the distance is:
[tex]D = \frac{25\sqrt{13}}{13}[/tex]

3.) An attorney charges a fixed fee of $250 for an initial meeting and $150 per hour for all hours
worked after that. The equation represents his total fee is y=150x + 250. Find the value of y
for the following hour(s) (x) that he has worked: {0, 1, 5, 10, 15, 303
Answer:
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Attorney A becomes a better deal at 5 hours

Answer:
x = 10 yd
Explanation:
These triangles are based on proportions. 12 yd is proportional to 18 yd, and x yd to 15 yd. We want to find x. We'll use the rule of three to calculate the unknown number.
12/18 = x/15
x = (12 · 15)/18
x = 10 yd (10 yards from the hut to the gold coins)

Leanne has an assignment where she is required to name something that qualifies as nonmaterial culture. What would BEST demonstrate this concept?
A. the belief that no one should kill another person
B. the lyrics to a song on the Internet
C. clothing that was made by a local craftswoman
D. a cell phone app that helps people find a friend
Answer:
A.
Step-by-step explanation:
The best option that would demonstrate this concept would be the belief that no one should kill another person. This is because out of all the available options this is the only intangible "material" that actually affects a population's culture. Such a belief or idea would make a population create their entire culture around such a belief as well as the other thoughts and ideas that define what is write and wrong to a culture.

Jen has a bag of marbles. There are 5 blue, 6 red and 7 white marbles in the bag. Jen pulls out a blue marble and does not replace it. What is the probability that Jen will get another blue marble?
Answer:
75%
Step-by-step explanation:
Answer:
4/18
Step-by-step explanation:
It would be a 4/18 chance she would get another blue marble, because first you add all of the marbles together which is 5+6= 11 + 7 = 18, so there are 5 blue marbles, and we have a chance of pulling another blue one 5/18 but since we already took one out, there are only 4 blue marbles left, so it's a 4/18.
Find the Quetion of the line that passes through the points (1,6) and (5,2)
Answer:
[tex]y=-x+7[/tex]
Step-by-step explanation:
Equation of straight line is given as
[tex]y-y_1=m(x-x_1)[/tex]
where slope m is calculated as
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)[/tex]
[tex]m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1[/tex]
Equation of line that passes through the points (1,6) and (5,2)
[tex]y-6=-1(x-1)\\y=-x+7[/tex]
The water supply uses huge concrete pipes to drain stormwater.
a Find the external radius of a pipe.
b Find the Internal radius of a pipe.
c Find the volume of concrete necessary to make one pipe.
Answer:
a. External radius is 0.5 m.
b. Internal radius is 0.45 m.
c. Volume of concrete necessary to make one pipe is 0.37 [tex]m^{3}[/tex].
Step-by-step explanation:
a. It can be observed that the diameter of the pipe is 1 m.
External radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{1}{2}[/tex]
= 0.5
External radius = 0.5 m
b. Internal radius of the pipe can be determined by;
Internal radius = [tex]\frac{internal diameter}{2}[/tex]
But,
Internal diameter = 1 m - (2 x 0.05 m)
= 1 m - 0.10 m
= 0.9 m
Internal diameter = 0.9 m
So that,
Internal radius = [tex]\frac{0.9}{2}[/tex]
= 0.45
Internal radius = 0.45 m
c. Volume of concrete required = [tex]\pi[/tex][tex]r_{e} ^{2}[/tex]h - [tex]\pi[/tex][tex]r_{i} ^{2}[/tex]h
where [tex]r_{e}[/tex] is the external radius, and [tex]r_{i}[/tex] is the internal radius.
Volume of concrete required = [[tex]\frac{22}{7}[/tex] x [tex](0.5)^{2}[/tex] x 2.5] - [[tex]\frac{22}{7}[/tex] x [tex](0.45)^{2}[/tex] x 2.5]
= 1.9643 - 1.5911
= 0.3732
The volume of concrete necessary to make one pipe is 0.37 [tex]m^{3}[/tex].
