Rose wants to determine whether her neighbors would be interested in buying candles in her upcoming fundraiser. She stops at every other house on her street to ask her neighbors' opinions.

1. Self-selected sample
2. systematic sample
3. simple random sample
4. Convenience sample

Answer:

Step-by-step explanation:

Because lines [tex]m[/tex] and [tex]n[/tex] are parallel, angles 1, 3, 4, 6 are equivalent, and all remaining angles are also equivalent.

Knowing this, you can set up the following equation:

[tex]86 = 2x + 25[/tex]

[tex]86 - 25 = 2x[/tex]

[tex]61 = 2x[/tex]

[tex]x = 30.5[/tex]

Answer:

x = 30.5

angle 1: 94 degrees

angle 2: 86 degrees

angle 3: 94 degrees

angle 4: 94 degrees

angle 5: 86 degrees

angle 6: 94 degrees

Answer:

Step-by-step explanation:

12(2y+1)-18y=36  <---- Distribute 12 into 2y+1

24y+12-18y=36 <----- Subtract 24y by 18y

6y+12=36 <---- Subtract 12 from 36

6y=24  <---- Divide 6 by 24

y=4

Answer:

16 cm^2

Step-by-step explanation:

The sqaure is 2*2=4

base x hieght  for triangle then divide by one half

so

2 x 2 = 4

3*2 =6 then 6/2=3

3*4=12

12+4=16

16 is the answer

Answer:

[tex](b)\\\tan x, \cot x[/tex]

Step-by-step explanation:

Given

trigonometric function is

[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]

Applying trigonometric formulae

[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]

[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]

option (b) is correct

[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

Complete question :

Six jurors are to be selected from a pool of 20 potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, 2 of the 20 prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If 6 jurors are selected at random from this group of 20, find the probability that the number of potentially prejudiced jurors among the 6 selected jurors is ;

a. exactly 1

b. none

c. at most 2

Answer:

0.442 ; 0.479 ; 1

Step-by-step explanation:

Given:.

Total number of candidates = 20

Number of jurors to be selected = 6

Number of prejudiced jurors = 2

Required outcome / Total possible outcomes :

Using the combination formula :

nCr = n! ÷ (n-r)!r!

1.)

P(number of prejudiced jurors is exactly 1) :

[2C1 * 18C5] ÷ 20C6

(2*8568)÷ 38760

= 0.442

B.)

P(None of the jurors is prejudiced) :

[2C0 * 18C6] ÷ 20C6

(1 * 18564) ÷ 38760

= 0.479

C.)

P(at most 2 of the jurors are prejudiced)

P(x =0) + p(x = 1) + p(x = 2)

P(x = 2) :

[2C2 * 18C4] ÷ 20C6

(1 * 3060) ÷ 38760

= 0.079

P(x =0) + p(x = 1) + p(x = 2)

(0.479 + 0.442 + 0.079)

= 1

Answer:

hypergeometric

Step-by-step explanation:

For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.

There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.

Answer:

The greatest common factor is 7

[tex]35 + 14 = 49[/tex]

Step-by-step explanation:

Given

[tex]35 + 14 =[/tex]

Required

Apply distributive property

Express 35 as 7 * 5 and 14 as 7 * 2

[tex]35 + 14 = 7 * 5 + 7 * 2[/tex]

Apply distributive property

[tex]35 + 14 = 7 ( 5 + 2)[/tex]

The greatest common factor is 7

Solving further to get the solution

[tex]35 + 14 = 7 * 7[/tex]

[tex]35 + 14 = 49[/tex]

Answer:

7(5+2)

Answer:

y < 12

Step-by-step explanation:

Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12

Please answer my question

Answer:

a = 15, b = - 14

Step-by-step explanation:

Given the 2 equations

[tex]\frac{a}{5}[/tex] - [tex]\frac{b}{2}[/tex] = 10 ( multiply through by 10 to clear the fractions )

2a - 5b = 100 → (1)

a - b = 29 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the a- term

- 2a + 2b = - 58 → (3)

Add (1) and (3) term by term to eliminate a

0 - 3b = 42

- 3b = 42 ( divide both sides by - 3 )

b = - 14

Substitute b = - 14 into (2) and evaluate for a

a - (- 14) = 29

a + 14 = 29 ( subtract 14 from both sides )

a = 15

Answer: x=20 y=20√2

Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)

Answer:

area of square=side²

36/49yd²=side²

(36/49yd²)²=side

6/7 yd=side

Answer:

s = [tex]\frac{6}{7}[/tex] yd

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the length of side )

Given A = [tex]\frac{36}{49}[/tex] , then

s² = [tex]\frac{36}{49}[/tex] ( take the square root of both sides )

s = [tex]\sqrt{\frac{36}{49} }[/tex] = [tex]\frac{\sqrt{36} }{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

Answer:

538826 ml

Step-by-step explanation:

Answer:

538826 mL

Step-by-step explanation:

:)

a. 2⁵ × 2^(3) = 2^(a) is a = 8.

b. 7⁴/[tex]7^b[/tex] = 7⁻² is b = 6.

c. [tex]8^c[/tex] = 1/64 is c = - 2.

Some common rules of exponents are

[tex]{a^b}\times{a^c} = a^{b + c}[/tex].

[tex]\frac{a^b}{a^c} = a^{b - c}[/tex]

We can only add and subtract exponents only when we have the same base.

Given,

2⁵ × 2³ = [tex]2^a[/tex].

[tex]2^{5+3}[/tex]= 2^(a).

[tex]2^8[/tex] = [tex]2^a[/tex]

a = 8.

[tex]\frac{7^4}{7^b}[/tex] = [tex]7^{-2}[/tex]

[tex]7^{4-b}[/tex] = [tex]7^{-2}[/tex].

4 - b = - 2.

- b = - 6.

b = 6.

[tex]8^c[/tex] = 1/64.

[tex]8^c[/tex] = 1/[tex]8^2[/tex].

[tex]8^c[/tex] = [tex]8^{-2}[/tex]

c = - 2.
