A magazine asks its readers to complete a survey on their favorite music and TV
celebrities. Classify the sample as one of the following.
A simple
B stratified
C convenience
D self-selected
Answer:
C convenience
Step-by-step explanation:
Convenience sampling (also known as availability sampling) is a type of non-probability sampling method in which data is collected from population members who are readily available for survey. An example for convenience sampling is the use of questionnaires or magazine to ask questions.
It is the most commonly used method of sampling because it is cheap incredibly prompt and uncomplicated.
Answer:
The correct option is;
D. Self-selected
Step-by-step explanation:
Self-selected sampling also known as volunteer sampling is a sampling method in which participants are those that voluntarily respond to an advert or to the request of the researcher who ask for members of the population to take part in the study
The magazine in the question has put out a survey of which the magazine is asking readers to complete and the readers can then decide if they wish to participate in the study which is a form of self-selected sampling.

Please help me find the surface area. Please explain, but not so its confusing like common core. Thanks.
Answer:
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Nine friends went on a camping trip a campsite costs 40 per night for the first 4 people and campers can pay an extra fee for each additional person if the group of friends rented one campsite for one night and paid 80 how much did the campground charge for each additional person
Answer:
8 dollars per extra person
Step-by-step explanation:
subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8
Answer:
$8 charge for each additional person
Step-by-step explanation
$40/night for each person
First 4 people already paid.
Leftover are 5 people.
9-4=5
Since first 4 people paid, the rest to be paid is $40.
$80-$40=$40
To find the charge for each person, divide the amount of money left by the amount of people left.
40÷5= 8
$8 is the additional charge for each additional person.
Javier constructed a square by drawing two congruent triangles. Which shows one of the triangles he could have used? A triangle with angles 45 degrees, 45 degrees, and 90 degrees. 2 sides are congruent. A triangle with angles 55 degrees, 35 degrees, and 90 degrees. A triangle with angles 65 degrees, 65 degrees, and blank. A triangle with 3 angles of 60 degrees. All sides are congruent.
Answer:
(A)A triangle with angles 45 degrees, 45 degrees, and 90 degrees. 2 sides are congruent.
Step-by-step explanation:
If Javier wants to construct a square by drawing two congruent triangles.
One of the angle of the triangle must be equal to 90 degrees to form one of the vertex of the square.The other two sides of the triangle must be equal(congruent) to form the two adjacent side lengths of the square. This gives rise to an Isosceles Triangle with base angles of 45 degrees each.Therefore, the triangle which could be used is a triangle with angles 45 degrees, 45 degrees, and 90 degrees.
The correct option is A.
Answer:
its a
Step-by-step explanation:
Which of the following represents the translation of A (1, −2) along the vector <−5, 1> and then the vector <3, 0>?
A. A (1, −2) → A ′(2, −7) → A ″(6, −7)
B. A (1, −2) → A ′(−4, −1) → A ″(−1, −1)
C. A (1, −2) → A ′(−5, 1) → A ″(3, 0)
D. A (1, −2) → A ′(−5, −2) → A ″(−15, 0)
Answer:
B. A (1, −2) → A ′(−4, −1) → A ″(−1, −1)
Step-by-step explanation:
When you see anything in between <> (let's say <a, b> are the numbers), it basically means <x+a, y+b>.
So if you replace a with -5, b with 1, and x and y with (1, -2) you get...
= (1 + (-5), -2 + 1)
= (1-5, -1)
= (-4, -1) ----------> Those are the coordinates of the new point.
But wait, it says that we now have to translate along the vector <3, 0>
So (-4, -2) become the new (x, y) coordinates and <3, 0> become the new a, b
= (-4+3, -1 + 0)
= (-1, -1)
That means that the coordinates of point A'' are (-1, -1)
Another way you could do this is by combining the two translations to just do one translation. It'll skip over the middle step, but will still give you the correct answer.
You would combine them by adding the translations of the x-coordinates together and the y-coordinates together
= <-5 + 3, 1 + 0 >
= <-2, 1>
Now you translate the point by this vector and...
= (1 - 2, -2 + 1)
= (-1, -1)
Tada! It works!
Therefore, the answer is B.

A chord is 15 cm long. It is 9 cm from the center of the circle. What is the radius of the circle?
Answer:
a²+b²=c²
7.5²+9²=c²
137.25=c²
√137.25=c²
11.72.... = c
The Radius of the circle is approximately 11.72cm
Step-by-step explanation:
Using this data. Create a Triangle with the Chord and Center of the dot. We know the distance between the chord and center which is one length of one of the sides.
We split the chord from the intersecting line from the center to the chord making the second line being 7.5cm
After We draw a line from the center of the circle to where the chord meets to the edge of the circle to create the triangle
We now have 2 measurements and can use Pythagorean Theorem to determine the radius from the missing length of the triangle.

Above are two different models of the same triangular handkerchief. If the area of the model on the right is 108 sq cm, what is the area of the model on the left?
A.
27 sq cm
B.
54 sq cm
C.
12 sq cm
D.
36 sq cm
Answer:
54
Step-by-step explanation:
The area of the model on the left is 12[tex]cm^{2}[/tex]
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
SCALE FACTOR FORMULAScale DirectionScale Up (smaller to larger) = [tex]\frac{Larger figure measurement }{Smaller figure measurement}[/tex]
Scale Down (larger to smaller) = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]
According to question
area of right triangle which have (1cm= 2inch) is 108 [tex]cm^{2}[/tex] .
and Left triangle have (1cm= 6inch)
we will convert cm into inch for right triangle
area of right triangle = 108 [tex]cm^{2}[/tex]
as 1 cm = 2inch
1 [tex]cm^{2}[/tex] = 4 [tex]inch^{2}[/tex]
therefore,
108 [tex]cm^{2}[/tex] = 4 * 108 [tex]inch^{2}[/tex]
as mentioned that two different models of the same triangular handkerchief
and left triangle is 1 cm = 6 inch
1 [tex]cm^{2}[/tex] = 36 [tex]inch^{2}[/tex]
now we have to scale down as we have to larger to smaller
Scale Down (larger to smaller) = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]
= 4*108 / 36
= 12
Hence, the area of the model on the left is 12[tex]cm^{2}[/tex]

Answer:
A). X is 80 degrees
Step-by-step explanation:
B). We know this because AD and EH are congruent. Since B and F are also congruent, then x and the angle above B must be congruent. So, the angle an=bove B is 80 degress, which makes line AD 180 degrees, or a straight line. that must mean that x is 80 degrees as well.

Figure CDEF is a parallelogram.
Parallelogram C D E F is shown. The length of F C is 6 n minus 1, the length of C D is 4 n + 2, and the length of D E is 5 n + 9.
Which equations are correct? Select three options.
n = 10
n = 7
CF = 59
FE = 42
CD = 30
Answer: A, C, D
Step-by-step explanation: The other person accidentally put 49 instead of 42
The equations that are correct are n = 10, CF = 59 and FE = 42
Properties of a parallelogramFrom the attached diagram, we can see that the opposite side of the parallelogram are equal, hence;
DE = CF
6n - 1 = 5n + 9'
Find the value f n
6n - 5n = 9 + 1
n = 10
CF = 5n + 9
CF = 5(10) + 9
CF = 59
For the measure of FE
FE = 4n + 2
FE = 4(10) + 2
FE = 42
Hence the equations that are correct are n = 10, CF = 59 and FE = 42

Find the MAD of the data set 26,34,66,71,76,82,88,95. show work
Answer:
MAD mean absolute deviation = 18.9
Step-by-step explanation:
mean: 26 + 34 + 66 + 71 + 76 + 82 + 88 + 95 = 538/8 = 67.25
26 - 67.25 = 41.25
34 - 67.25 = 33.25
66 - 67.25 = 1.25
71 - 67.25 = 3.75
76 - 67.25 = 8.75
82 - 67.25 = 14.75
88 - 67.25 = 20.75
95 - 67.25 = 27.75
(MAD) mean absolute deviation: 41.25 + 33.25 + 1.25 + 3.75 + 8.75 + 14.75 + 20.75 + 27.75 = 151.5/8 = 18.9
