Answer: sampling variation

Step-by-step explanation: took the quiz

The margin of error is given by the sampling variation of the proportion of customers

The most accurate type of probability sampling is random sampling. Each person in a population has an equal probability of getting selected for the sample thanks to this method of sampling.

This kind of sampling is perfect for highly controlled investigations where it is unacceptable to have human bias in the selection of the sample.

Each sampling unit in a population has an equal probability of being included in the sample when using simple random sampling (SRS). As a result, each potential sample has an equal probability of being chosen.

Given data ,

Let the margin of error be represented as A

where the value of A is

The confident interval is = 96 %

And , the value of sample is of 200 customers

where the warranty claims from 0.15 to 0.28

So , the cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim

Therefore , it is a sampling variation

Hence , the situation is a sample variation

Answer:

144

Step-by-step explanation:

We can see that every 2 boxes has 24 peaches in it. That means that every single box would have 12 in it. Then it is just simple multiplication from there. 12 * 12 = 144.

Hope that this helps!

Answer:

y=3x-2

Step-by-step explanation:

We know the equation ends in -2 because when x is zero, y is -2

To find the rest of the equation take any other point and take away the -2 from y

Then divide the y by the x to see how may times larger (or smaller) the y is then the x

(I chose -14)

-12÷-4=3

y=3x

the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table

Answer:

y = 2(x + 3)² - 4

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square

y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms

  = 2(x² + 6x) + 14

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 6x

y = 2(x² + 2(3)x + 9 - 9 ) + 14

  = 2(x + 3)² - 18 + 14

  = 2(x + 3)² - 4 ← in vertex form

Answer:

x= -3 and y= 0

Step-by-step explanation:

5x+2y=-15

2x-2y=-6    

7x        =-21

x= -3

Putting value of x in equation 1  

5(-3) +2y=-15

-15+2y= -15

2y= 0

y= 0

This can be solved with the help of matrices

In matrix form the above equations can be written in the form

[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex]  [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]

Let

[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex] = A  [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = X  and  [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]= B

Then AX= B

or X= A⁻¹ B

where  A⁻¹= adj A/ ║A║   where mod A≠ 0

adj A=  [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex]

║A║= ( 5*-2- 2*2)= -10-4= -14≠0

X= A⁻¹ B

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]    =- 1/14  [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex]   [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]    =- 1/14     [tex]\left[\begin{array}{ccc}-2*-15&+ -2*-6\\-2*-15&+ 5*-6\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  =- 1/14 [tex]\left[\begin{array}{ccc} 30&+12\\30&+-30\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  =- 1/14 [tex]\left[\begin{array}{ccc}42\\0\\\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-42/14\\0/-14\\\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-3\\0\\\end{array}\right][/tex]

From here x= -3 and y= 0

Answer:

Rachel worked for [tex]3\frac{2}{3}[/tex] hours

Step-by-step explanation:

See comment for complete question

Given

Let

[tex]D = Dominic[/tex]

[tex]R = Rachel[/tex]

So:

[tex]D = 2\frac{3}{4}[/tex]

and

[tex]R =1\frac{1}{3}[/tex] as long as D

Required

Determine the number of hours spent by Rachel

This implies that:

[tex]R =1\frac{1}{3}[/tex] as long as D

Rewrite as:

[tex]R =1\frac{1}{3} * D[/tex]

Substitute: [tex]D = 2\frac{3}{4}[/tex]

[tex]R =1\frac{1}{3} * 2\frac{3}{4}[/tex]

Express as improper fraction

[tex]R =\frac{4}{3} * \frac{11}{4}[/tex]

This gives:

[tex]R =\frac{1}{3} * 11[/tex]

[tex]R =\frac{11}{3}[/tex]

Express as mixed numbers

[tex]R =3\frac{2}{3}[/tex]

Hence, Rachel worked for [tex]3\frac{2}{3}[/tex] hours
