Answer 1
Answer:  Yes it is a function.

Reason:

There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.

If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.

A group of friends went to lunch. Click on all the correct answers below according to the Letters A, B, and C.

A Their original bill cost $50.00, but they had a coupon for 20% off their meal. Find the discounted price (before tax and tip).
B A sales tax of 7% was added. What was the total amount including sales tax?
C The group chose to tip 20%. What is the total amount that their bill cost including tax and tip?

Answers

Answer:

A. 10.00, so total price is currently 40.00

B. 42.8

C. Total amount is 51.36

Step-by-step explanation:

20% of 50 is 10. Taking off 10% (your discount) would make it 40.

7% of 40 is 2.8. The total amount is now 42.8

20% (your tip) of 42.8 = 8.56.

42.8 + 8.56 = 51.36.

51.36 is your final cost.

Find the critical value Zc necessary to form a confidence interval at the level of confidence c=0.82 what does Zc=

Answers

Answer:

The z-critical values are:

[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]

Step-by-step explanation:

The confidence level is, c% = 82%.

The significance level for the two tails are:

Left tailed:

[tex]\frac{\alpha}{2} =\frac{1-c\%}{2}[/tex]

   [tex]=\frac{1-0.82}{2}\\\\=\frac{0.18}{2}\\\\\=0.09[/tex]

Right tailed:

[tex]1-\frac{\alpha}{2} =1-\frac{1-c\%}{2}[/tex]

         [tex]=1-0.09\\\\=0.91[/tex]

The z-critical values are:

[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]

*Use the z-table.

A door delivery florist wishes to estimate the proportion of people in his city that will purchase his flowers. Suppose the true proportion is 0.05. If 408 are sampled, what is the probability that the sample proportion will differ from the population proportion by greater than 0.03?

Answers

Answer:

 The probability is  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is  [tex]p = 0.05[/tex]

    The sample size is  n =  408

Generally the standard deviation of the sampling distribution is mathematically represented as

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

=>    [tex]\sigma = \sqrt{\frac{ 0.05 (1- 0.05)}{408} }[/tex]

=>    [tex]\sigma = 0.0108[/tex]

Generally the probability that the sample proportion will differ from the population proportion by greater than 0.03 is mathematically represented as

        [tex]P( | \^ p - p| > 0.03) = P( \frac{|\^ p - p | }{\sigma } > \frac{0.03}{0.0108} )[/tex]

[tex]\frac{|\^ p -p |}{\sigma }  =  |Z| (The  \ standardized \  value\  of  \ |\^ p -p | )[/tex]

So    

       [tex]P( | \^ p - p| > 0.03) = P( |Z|> 2.778 )[/tex]

=>   [tex]P( | \^ p - p| > 0.03) = P( Z < 2.778) - P(Z < -2.777)[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.778  and  -2.778  is

     [tex]P( Z < 2.778) = 0.99727[/tex]

and

     [tex]P( Z < -2.778) = 0.0027347[/tex]

So

     [tex]P( | \^ p - p| > 0.03) = 0.99727 - 0.0027347[/tex]

=>  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

Step-by-step explanation:

(9x + 29)° + (93 - 5x)° + (10x + 2)° = 180°

9x + 29 + 93 - 5x + 10x + 2 = 180

14x + 124 = 180

14x = 56

x = 4

m∠A = (9(4) + 29)° = 65°

m∠C = (10(4) + 2)° = 42°  

m∠C < m∠A < m∠B

3x+2y=4,6x+3y=2 Solve the systems of equations by substitution

Answers

Answer:

x = -8/3, y = 6

Step-by-step explanation:

3x+2y=4   so x = (4-2y)/3

6x+3y=2

substiute x into the second equation

6((4-2y)/3) +3y = 2

2(4-2y) + 3y = 2

8 - 4y + 3y = 2

-y = -6

y = 6

Replace y into the first equation

3x + 2 (6) = 4

3x +12 = 4

3x = -8

x = -8/3

Three tickets to a movie costs $37.50. If all tickets were the same price, what would be the cost of 2 tickets?
