PLEASE HELP ASAP
How do you find the total for a purchase if there is sales tax?

Answer:

3/2 or 1 + 1/2

i havent done fractions in a long time but this is what i got from memory

you turn the 2/3 into 4/6 so they can easily be added together to get 9/6 which can be simplified to 3/2 or in proper form 1 + 1/2

Complete Question

The National Appliance Company makes refrigerators. One of its suppliers, the Exeter company, produces plastic shelves for the refrigerators and ships them in large lots. The National Appliance Company requires that the percentage of the plastic shelves that are defective be no more than 10%. If more than 10% are defective, the Prime Factor Company will reject the lot. To test this, the National Appliance Company randomly selects 573 of the shelves and has them inspected. It turns out that 70 are defective. Use this information and a 5% level of significance to determine if National Appliance should reject the batch.

Answer:

  The decision rule is  

Reject the null hypothesis  

The conclusion is  

There is no sufficient evidence to conclude that  proportion of defective shelf is less than or equal to 0.10  hence the National Appliance Company should reject that batch of shelfs

Step-by-step explanation:

From the question we are told that

    The population of defective plastics is  [tex]p = 0.10[/tex]

    The sample size is  n = 573

    The number of shelf that are defective is  k =  70  

     The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the sample proportion is mathematically represented as

           [tex]\^ p = \frac{k}{n}[/tex]

=>       [tex]\^ p = 0.1222[/tex]

The null hypothesis is [tex]H_o : p \le 0.10[/tex]

The  alternative hypothesis is  [tex]H_a : p > 0.10[/tex]

Generally the test statistics is mathematically represented as

            [tex]z = \frac{\^ p - p }{ \sqrt{\frac{p (1 - p)}{ n } } }[/tex]

=>          [tex]z = \frac{ 0.1222 - 0.10 }{ \sqrt{\frac{0.10 (1 - 0.10 )}{ 573 } } }[/tex]

=>          [tex]z = 1.77[/tex]

From the z table  the area under the normal curve to the right  corresponding to  1.77   is

       [tex]p-value = P(Z > 1.77 ) = 0.038364[/tex]

From the question we are told that  [tex]p-value < \alpha[/tex] hence

  The decision rule is  

Reject the null hypothesis  

The conclusion is  

  There is no sufficient evidence to conclude that  proportion of defective shelf is less than or equal to  0.10  hence the company should reject theat batch of shelfs

I don't want a lot for Christmas

There is just one thing I need

I don't care about the presents

Underneath the Christmas tree

I just want you for my own

More than you could ever know

Make my wish come true

All I want for Christmas is you, yeah

I don't want a lot for Christmas

There is just one thing I need

And I don't care about the presents

Underneath the Christmas tree

Santa Claus won't make me happy

With a toy on Christmas Day

I won't even wish for snow

And I'm just gonna keep on waiting

Underneath the mistletoe

To the North Pole for Saint Nick

Hear those magic reindeer click

'Cause I just want you here tonight

Holding on to me so tight

What more can I do?

Baby, all I want for Christmas is you

And the sound of children's laughter fills the air

And everyone is singing

I hear those sleigh bells ringing

Santa, won't you bring me the one I really need?

Won't you please bring my baby to me?

Oh, I don't want a lot for Christmas

D is the correct answer!

Hope this helped with the question you were looking for. Lmk on this problem if you need any help with any other questions!

The expression that can represent the length and the width are 2x - 3 and x + 2 respectively.

where

l = length

w = width

Therefore,

area = 2x² + x – 6

Let's factorise

2x²- 3x + 4x - 6

x(2x - 3) + 2(2x - 3)

Therefore,

(x + 2)(2x - 3)

Therefore, the expression that can represent the length and the width are 2x - 3 and x + 2 respectively.

Answer:

y = - 1.5x - 15

Step-by-step explanation:

Step 1:

- 3x - 2y = 30         Equation

Step 2:

- 2y = 3x + 30        Add 3x on both sides

Step 3:

y = - 1.5x - 15      Divide 2 on both sides

Answer:

y = - 1.5x - 15

Hope This Helps :)

Answer:   y = - 1.5x - 15

Step-by-step explanation:

First, we will add 3x to both sides of the equation.

-2y = 3x + 30

Next, we will divide 2 on both sides of the equation.

y = -1.5x - 15

Answer -  y = -1.5x - 15

What's the spinner?  How many numbers are on it?

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

Hi there! In order to solve this equation, all you have to do is distribute the 5 to the (y+10) and then shift like terms. Once you do that, you would get 5y+50=7y, and then you subtract the 5y from the 7y in order to get the 50 by itself. That would get you 2y, and from there, you just simply divide the value of 50 by 2y- getting you to 25 as the value of y. I hope this helped! <3 (Please mark as branliest if I got this right!)

Answer:

y = 25

Step-by-step explanation:

Distribute 5 (y+ 10) to get

5y + 50 = 7y

subtract the 5y from both sides to get

50 = 2y

divide the 2 from 2y on both sides to get

25 = y, or y = 25

Step-by-step explanation:

The table that shows the correct t and d values is

Distance Covered (m)           Time Taken (hr)

8                                               6

32                                              15

The table of values is given as:

Distance Covered (m)           Time Taken (hr)

8                                               6

16                                              12

32                                              15

48                                              18

The distance covered in 15 hours is 32 m and the time taken to cover 8 m is 6 hours

When these values are extracted, we have:

Distance Covered (m)           Time Taken (hr)

8                                               6

32                                              15

Answer as a fraction:  17/6

Answer in decimal form: 2.8333  (approximate)

==================================================

Work Shown:

Let's use the two black points to determine the equation of the red f(x) line.

Use the slope formula to get...

m = slope

m = (y2-y1)/(x2-x1)

m = (4-0.5)/(2-(-1))

m = (4-0.5)/(2+1)

m = 3.5/3

m = 35/30

m = (5*7)/(5*6)

m = 7/6

Now use the point slope form

y - y1 = m(x - x1)

y - 0.5 = (7/6)(x - (-1))

y - 0.5 = (7/6)(x + 1)

y - 0.5 = (7/6)x + 7/6

y = (7/6)x + 7/6 + 0.5

y = (7/6)x + 7/6 + 1/2

y = (7/6)x + 7/6 + 3/6

y = (7/6)x + 10/6

y = (7/6)x + 5/3

So,

f(x) = (7/6)x + 5/3

We'll use this later.

---------------------

We ultimately want to compute f(g(0))

Let's find g(0) first.

g(0) = 1 since the point (0,1) is on the g(x) graph

We then go from f(g(0)) to f(1). We replace g(0) with 1 since they are the same value.

We now use the f(x) function we computed earlier

f(x) = (7/6)x + 5/3

f(1) = (7/6)(1) + 5/3

f(1) = 7/6 + 5/3

f(1) = 7/6 + 10/6

f(1) = 17/6

f(1) = 2.8333 (approximate)

This ultimately means,

f(g(0)) = 17/6 as a fraction

f(g(0)) = 2.8333 as a decimal approximation
