Answer:

59 cents

Step-by-step explanation:

When finding the unit rate, you need to end up finding what is the price for one product (basically a fraction with one on the bottom) to find this I just did 3.55 / 6 which gave me 59 cents, the price of one coca cola bottle.

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.

Answer:

$25 I believe

Step-by-step explanation:

You would take $37.50 divided by 3 and get $12.50 which is the price of 1 ticket

Then you would multiply $12.50 x 2 to get $25

Answer: $25.00

Step-by-step explanation: First you would divide $37.50 by 3 and get the price of one ticket which would be 12.50. Then you would multiply 12.50 by two and get $25.00.      

32 is the correct answer. 40 times 0.8 because in decimal form, 80 percent equals 0.8:)

Answer:

32 80% of 40

Hope it is correct

If not I am sorry I tried my best

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

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]

Answer:

It is graph A

Step-by-step explanation:

Answer: A it your answer.

Step-by-step explanation:

Answer:

AB, BC, AC

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∠B = [93- 5(4)]° = 73°

m∠C = (10(4) + 2)° = 42°  

m∠C < m∠A < m∠B

AB < BC < AC

Answer:

[tex]-x-3[/tex]

Step-by-step explanation:

They want you to simplify the expression.

Step 1: Apply the distributive property.

[tex]\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)[/tex]

Step 2: Cancel the common factor of 5.

[tex]x+\frac{1}{5} (-15-2x)[/tex]

Step 3: Cancel the common factor of 5.

[tex]x-3-2x[/tex]

Step 4: Subtract 2x from x.

[tex]-x-3[/tex]

Answer:

Step-by-step explanation:

Speed = rate = slope

Find slopes:

Table:

(10, 70)

(20, 140)

Speed = 7 km/min

Graph:

(6, 90) , (4, 60)

Speed = (90 - 60) / (6 - 4) = 30/2 = 15 km/min. the greater cruising speed

Answer:

3y+4

Step-by-step explanation:

9y-6y=3y

Answer:

y=-8x+2

Step-by-step explanation:

The reason that is the answer is because the slope-intercept form is y=mx+b where m is the slope and b is the y-intercept so y=mx+b would be y=-8x+2

it had many purposes includeing to entertain and to compete

Answer:

A proportional relationship is any relationship that stays constant. since both sides of the equation do not change, this is a proportional relationship

Answer:

Step-by-step explanation:

The slope intercept form of a line is Y=MX + B where M is the slope and B is the y-intercept.

We know both of these so the equation turns into Y=1/2X-3
