Answer: Stratified random sampling.
Step-by-step explanation:
In a simple random sampling, every one has an equal chance of being chosen. This case is quite different.
In this case, since the analyst selects a sample of 400 car buyers by randomly sampling 100 buyers of each brand, this is a stratified random sampling since the outcome was already divided into 100 cars for each brand.

Answer
62
5.3
65
5.8
2.5
Step-by-step explanation:
FOr the first one we have the opposite and adjacent side, so we'll use TOA
let x= angle
tan(x)=4.7/2.5
x=61.99 or 62
2.) for this one we can just use pathagoryeous thereom
2.5²+4.7²=c²
28.34=c²
c=5.323
3.) For this one we know that the angles in a traingle must add to 180
let x= missing angle
25+90+x=180
x=65
4.) For this one we have the adjacent side but need the hypotonouse
we will therefore use CAH
cos(25)=5.3/x
5.3/(cos(25))=x
x=5.8
5.) For this one we will just use the pathagoryeous to solve for the missing side
a²+5.3²=5.8²
a²=6.107
a=2.5

ABCD is a parallelogram. Which statements are true?
Answer:
Final Answer: Statements 1, 2 and 4 are correct.
Step-by-step explanation:
Finding value of y:
2y + 3 = 15 => 2y = 12 => y = 6;
Finding value of x:
6x + 5 = 77 => 6x = 72 => x = 12;
Statement Number 1:
y² > 2x ? => 6² > 2 * 12 ? => 36 > 24 ?
Yes, 36 is bigger than 24, therefore statement one is correct.
Statement 2:
x = 2y ? => 12 = 2 * 6? => 12 = 12?
Yes, 12 is equal to 12. Statement 2 is correct.
Statement 3:
x + 2 = y + 10 ? => 12 + 2 = 6 + 10? => 14 = 16?
No, 14 is not equal to 16. Statement 3 is incorrect.
Statement 4:
y + 4 > x - 4 ? => 6 + 4 > 12 - 4 ? => 10 > 8 ?
Yes, 10 is bigger than 8. Statement 4 is correct.

Step-by-step explanation:
As we can see the opposite sides are equal and the opposite angles are equal so it is a parallelogram. Hence
5x = 70° { opposite angles of a parallelogram are equal }
x = 14°
Hope it will help :)⏩❤
The value of x in the given figure is 14, Option A is correct.
We need to find the value of x in the given figure.
The opposite angles in the given figure are equal.
So when we equate both the angles we get an equation
5x=70
Divide both sides by 5
x=70/5
x=14

PLS HELP I REALLY NEED TO GET THIS RIGHT!!
Answer:
x = 66°
Step-by-step explanation:
First, you can use exterior angle theorem to say that
[tex]m<JIH = m<JDI + m<DJI[/tex]
and you can substitute to get:
105° = 39° + m<DJI
m<DJI = 66°
m<DJI and m<AJF are vertical angles, so they equal each other:
m<DJI = m<AJF
m<AJF = x = 66°

If someone can do this whole thing for me I will give brainiest.
Answer:
A= x r^2
A= x r x r
r means radius
The value of pi() is 3.14
r^2 means radius x radius
Substitute the radius for r: A= x 7^2
Square the radius: 7 x 7= 49
Area in terms of pi(): 49
Area in terms of square inches: 153.86 in^2
Divide the diameter by 2: 12 ÷ 2= 6
Substitute the radius for r: A= x 6^2
Square the radius: 6 x 6= 36
Area in terms of pi(): 36
