A significance level of 5% (more commonly referred to as 95%) corresponds to a statement that (only) a probability of 5% or less is that a particular randomly generated observation is accepted as significant.
In this example, the p-level (the true probability that the observations are randomly generated) is less than 5% (0.0421 <0.05), so we can draw the conclusion that the observations are significant.
p = 0.0421 means that the probability is only 0421/1000. The choice of significance level to reject the null hypothesis is optional. Traditionally, 5%, 1%, and 0.1% levels have been used. In rare situations, a 10% significance level is also used.

Step-by-step explanation:
Putting the data on the line plot is not too bad. Just put an x above the number on the numberline. If a number in the data set repeats, just stack those x's up over the numberline. It seems like the hardest part is labelling the number line. Each tick mark can be 1/8. On the image I wrote all the fractions in eighths at the bottom, then to label the numberline I used the simplified fractions. For example I started with 1 3/8 because it was the smallest number in the data set. Next is 1 4/8, but simplified that is 1 1/2. So 1 1/2 is how we label the numberline.
There were 12 pieces of data, but really only six numbers because some were repeated.
Stack x's above the numberline. Done! You have a line plot. See image.

Sarai loves music and decides to paint a music staff on her bedroom wall. She knows that it is important to make the lines parallel, or the end result will not look correct. She pencils in the image below, but before she uses paint, she wants to make sure the lines are parallel. Remembering what she has learned in Geometry class, she uses a piece of tape to make a transversal and decides to measure some angles.
Using Sarai’s measurements, Line 1 must be parallel to Line 3 according to which postulate or theorem?
Can you also please explain how you got the answer? thank you <3
Using Sarai's measurements, Line 3 must be parallel to Line 5 by option (A) Converse of Alternate Exterior Angles Theorem.
What is the Alternate Exterior Angles theorem?The alternate Exterior Angles theorem states, "If two lines are parallel and they are intersected by the same straight line then the alternative exterior angles formed by the figure are equal to each other."
The converse of this theorem states that "If two lines intersected by one transverse and formed alternate exterior angles, and if they are equal to each other then that two lines are parallel to each other."
Here in Sarai's measurement, we can conclude that Line 3 and Line 5 are intersected by one straight line, and the formed alternate exterior angles both are 65, which shows they are equal to each other.
Hence by Converse of the Alternate Exterior Theorem, we can say that both lines are parallel to each other.
So, Line 3 must be parallel to Line 5 according to the Converse of Alternate Exterior Angles Theorem.
Hence Option (A) is correct.

Step-by-step explanation:

A telegraph pole stands on a line joining two points P and Q on the ground.
The telegraph pole is 9 m tall. The angle of depression of the top of the pole to point P
is 4°. The angle of depression of the top of the pole to point Q is 7º. What is the
horizontal distance between P and Q.
Step-by-step explanation:
let's call the top of the pole T, and the ground point of the pole G.
so, the situation gives us 2 right-angled triangles:
PTG and QTB.
from both triangles we know one leg (TG, the pole = 9 m), the inner angles at G (90° in both cases), and actually the inner angles at T, because we know the angles of depression there.
the inner triangle angles at T are just the complementary angles of the angles of depression (that means they add up together to 90°).
the inner angle at PTG = 90 - 4 = 86°
the inner angle at QTG = 90 - 7 = 83°
and because the sum of all angles in a triangle is always 180°, we even know the third angles at P and Q :
angle P = 180 - 90 - 86 = 4°
angle Q = 180 - 90 - 83 = 7°
yes, they are the same as the angles of depression (must be the same).
so, we know from both triangles 1 side and all 3 angles.
with the law of sine we can get every missing side.
particularly we need the second legs (sides in the ground) to get the distance between both points.
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c being the sides always opposite of their related angles.
TG/sin(4) = PG/sin(86)
PG = 9×sin(86)/sin(4) = 128.7059963... m
TG/sin(7) = QG/sin(83)
QG = 9×sin(83)/sin(7) = 73.29911785... m
the distance between P and Q can have now 2 solutions :
if P and Q are on different sides of the pole, then
PQ = 128.7059963... + 73.29911785... = 202.0051142... m
but if they are on the same side of the pole, then their distance is
PQ = 128.7059963... - 73.29911785... = 55.40687846... m
due to the phrasing of the first sentence I suspect the first solution to be right.
but just in case, I gave you also the second possible solution.

How many outfits can be made with 40 shirts and 15 pairs of pants
Answer:
600
Step-by-step explanation:
So I'm assuming an outfit is considered one shirt, and one pair of pants... But anyways, this can be expressed in a graph. So for each shirt, there are going to be 15 possible pants you can chose. And this goes for each shirt. So in other words you're simply adding up 15, 40 amount of times. Or 15 * 40, which is 600. I attached an image that illustrates this graph. You can also think of it in terms of choosing one of 15 pants and then for each pant, there are 40 possible shirts to choose from. This is essentially adding up 40, 15 times, or in other words 40 * 15, which is going to get you the same result. But in my diagram I used it in terms of choosing a shirt first.
Answer:
600
Step-by-step explanation:
Pair 1 of pants goes with 40 shirts
Pair 2 of pants goes with 40 shirts
Pair 3 of pants goes with 40 shirts
Pair 4 of pants goes with 40 shirts
Pair 5 of pants goes with 40 shirts
Pair 6 of pants goes with 40 shirts
Pair 7 of pants goes with 40 shirts
Pair 8 of pants goes with 40 shirts
Pair 9 of pants goes with 40 shirts
Pair 10 of pants goes with 40 shirts
Pair 11 of pants goes with 40 shirts
Pair 12 of pants goes with 40 shirts
Pair 13 of pants goes with 40 shirts
Pair 14 of pants goes with 40 shirts
Pair 15 of pants goes with 40 shirts
Add up everything (not including the 1,2,3,4,5,...14,15 pairs of pants because each pair of pants goes with 40 different shirts so u just add up all the 40's) and you would get 600 outfits.

Solve the linear system.
x + y = -3
y = 2x
Answer:
x = -1
y = -2
Step-by-step explanation:
You can use the method of substitution to solve this equation. Since you know that y= 2x, you can substitute that value into x + y = -3:
x + (2x) = -3
Combine like terms:
3x = -3
x = -3/3
x = -1
Now that you know the value of x, you can substitute it into any of the two equations (I'll be choosing y = 2x)
y = 2x
y = 2 (-1)
y = -2
So your solution is x = -1, y = -2
Point form: (-1, -2)

Segment FG is on a number line with point F at 1.2. Point H lies on FGat 3.15. Point H is the length of FGfrom point G. What
are the location of G and the length of FG?
Type the correct answer in each box. Use numerals instead of words.
The location of G is?
The length of FG is?
A number line is a line that shows the locations of all directed numbers. The answers required to the question are:
i. The location of G is 2.18.
ii. The length of FG is 0.98.
A number system is a system that can be used to locate the position of directed numbers on a number line. A number line has two ends: positive and negative ends. This starts from negative infinity to positive infinity. Thus all numbers can be located on a number line.
Directed numbers are numbers that have either a positive sign or a negative sign. Thus all numbers are directed numbers.
From the given question, let the distance between FG and GH be represented by x (since Point H is the length of FG from point G).
Thus,
Point FH = 3.15 - 1.20
= 1.95
x = [tex]\frac{FH}{2}[/tex]
= [tex]\frac{1.95}{2}[/tex]
x = 0.975
So that,
Location of point G = 1.200 + 0.975
= 2.175
Therefore, the location of G is 2.175 (2.18). And the length of FG is 0.975 (0.98).
