34 total pencils......16 were sharpened...that means (34 - 16 ) = 18 pencils that were not sharpened.

so the ratio of unsharpened pencils to sharpened pencils is :
18:16 which reduces to 9:8 or 9/8 or 9 to 8 <==

Answer:

        1  

= -----------

   6(x + 7)

Step-by-step explanation:

3x - 21      x^2 - 49

----------- ÷ -------------

18x - 18        x - 1

3x - 21          x - 1

----------- ×  -------------

18x - 18       x^2 - 49

Factor the top left:

3x - 21  = 3(x - 7)

Factor the bottom left:

18x - 18 = 18(x - 1)

Factor the new bottom right:

x^2 - 49 = (x + 7)(x - 7)

Multiply and simplify the faction:

3(x - 7)            x - 1

----------- ×  -----------------

18(x - 1)       (x + 7)(x - 7)

        1  

= -------------

   6(x + 7)

Answer:

1) The discount is $4.05

The sale price is $18.45

2) The discount is $10

The sale price is $30

3) The discount is $2.6

The sale price is $23.4

Step-by-step explanation:

1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.

Actual Price= $22.50

Discount = 18%

Finding discount:

18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05

So, the discount is $4.05

Finding Sale Price

The sale price can be found by: Sale\;Price=Actual\:Price-Discount

Putting values and finding sale price:

Sale\:Price=22.50-4.05\\Sale\:Price=18.45

The sale price is $18.45

2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.

Actual Price= $40.00

Discount = 25%

Finding discount:

25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10

So, the discount is $10

Finding Sale Price

The sale price can be found by: Sale\;Price=Actual\:Price-Discount

Putting values and finding sale price:

Sale\:Price=40.00-10\\Sale\:Price=30

The sale price is $30

2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.

Actual Price= $26.00

Discount = 10%

Finding discount:

10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6

So, the discount is $2.6

Finding Sale Price

The sale price can be found by: Sale\;Price=Actual\:Price-Discount

Putting values and finding sale price:

Sale\:Price=26.00-2.6\\Sale\:Price=23.4

The sale price is $23.4

Answer:

The required probability is 0.0855

Step-by-step explanation:

Consider the provided information.

The daily revenue has mean $7200 and standard deviation $1200.

\mu_{\bar x}=7200

\sigma=1200

The daily revenue totals for the next 30 days will be monitored.

\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}

\sigma_{\bar x}=\frac{1200}{\sqrt{30}}=219.089

As we know Z=\frac{\bar x-\mu_{\bar x}}{\sigma_{\bar x}}

Substitute \bar x=7500, \mu_{\bar x}=7200\ and\ \sigma_{\bar x}=219.089 in above formula.

Z=\frac{7500-7200}{219.089}=1.3693

From the standard normal table P( Z >1.3693) = 0.0855

Hence, the required probability is 0.0855
