A sofa with an original price of $600 is put on sale for $480.
What is the percentage discount on the cost of the sofa?

Answers

Answer:

20%

Step-by-step explanation:

Percentage discount on the cost of the sofa = 20%

What is percentage discount?

Percentage discount = (Absolute discount / Cost price) × 100

Given,

             Cost price =  $600

Absolute discount  =  Cost price - Selling price

Absolute discount  =  $600 - $480

                                = $120

Percentage discount = (Absolute discount / Cost price) × 100

                                   = (120/600) × 100

                                   = 120/6

                                   = 20%

Hence, percentage discount on the cost of the sofa = 20% .

US Weekly magazine claims that 32% of its readers believe Angelina Jolie was best dressed at the Academy awards. To verify this claim, how large a sample is needed for a 0.05 margin of error at a 95% confidence level?

Answers

Answer: 335

Step-by-step explanation:

Formula for sample size :

[tex]n=p(1-p)(\dfrac{z^*}{E})^2[/tex], where p =population proportion, z* = critical z-value, E = Margin of error.

Given: p = 32% = 0.32

E = 0.05

Critical z-value for 95% confidence = 1.96

Required sample size :

[tex]n=(0.32)(1-0.32)(\dfrac{1.96}{0.05})^2\\\\=334.372864\approx335[/tex]

Hence, the required sample size = 335

how do you graph this linear equation???​

Answers

Answer:

You can choose x as any value like x = 7

if x were to equal 7 then

the equation would be y = 2 times 7 - 1

2 times 7 = 14 and 14-1 = 13

y would be 13 ifi x was 7
