during the 40-minute time of talk? (1 point)

A Cell Phone Plan Has A Monthly Cost That Is Shown In The Table Below. What Is The Correct Statement

Answers

Answer 1

Answer:

Second from top...

The average rate of change is $0.07, meaning that for each minute of talk time, the monthly bill increases by $0.07.

Step-by-step explanation:

Pick any two points and calculate the slope which will represent the rate of change:

  (Minutes, Cost)

  (0, 9.95)

  (10, 10.65)

Rate of change:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (10.65 - 9.95) / (10 - 0)

             = 0.7 / 10

             = 0.07

y is cost

m is rate of change

x is minute(s) use

b is fixed monthly cost regardless if any minutes is used

  y = mx + b

  y = .07x + 9.95

a. State a conclusion about the null hypothesis.​ (Reject Upper H0 or fail to reject Upper H0
Choose the correct answer below.
A.Reject Upper H0 because the​ P-value is less than or equal to to α.
B. Reject Upper H0 because the​ P-value is greater than α.
C. Fail to reject Upper H0 because the​ P-value is greater than α.
D. Fail to reject Upper H0 because the​ P-value is less than or equal to α.
b. Without using technical​ terms, state a final conclusion that addresses the original claim. Which of the following is the correct​ conclusion?
A. The percentage of adults that would erase all of their personal information online if they could is less than or equal to 51​%.
B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51​%.
C. The percentage of adults that would erase all of their personal information online if they could is more than 51​%.
D. There is not sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51​%.

Answers

Answer:

A.Reject Upper H0 because the​ P-value is less than or equal to to α.

B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51​%.

Step-by-step explanation:

Given the claim :

Less than 51% will erase their personal information :

We take this as the null ;

H0 < 0.51 ;

Alternative hypothesis which is the opposite of the Null

H1 > 0.51

P value = 0.0148

α = 0.05

At α = 0.05 ; if p value is less than α ; reject the the Null

If p value is greater than Null ; then we fail to reject the Null

Pvalue < α

The P value is less than 0.05; then we reject the Null

B.) There is significance evidence to support the Alternative hypothesis claim, that the percentage of adult that would erase all their personal information online if they could is more Than 51%

An EWMA control chart uses λ = 0.5. What is the value of L such that the control limits of this EWMA control chart in the steady state have the same width with a 3σ X_bar control chart?

Answers

Answer:

5.199

Step-by-step explanation:

From the  information provided;

We know that λ = 0.5.

However, the control limits for a steady-state EMWA control chart is:

[tex]\mu_o \pm L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]

where;

[tex]UCL = \mu_o + L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]

[tex]LCL = \mu_o- L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]

Given that the data is chosen from an individual sample;

Then; we can express the width as:

[tex]L \sigma \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3 \sigma[/tex]

[tex]L \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3[/tex]

[tex]L \sqrt{\dfrac{0.5}{(2-0.5)}}= 3[/tex]

[tex]L \sqrt{\dfrac{0.5}{(1.5)}}= 3[/tex]

[tex]L \sqrt{0.333}= 3[/tex]

[tex]L\times 0.577= 3[/tex]

[tex]L=\dfrac{ 3 }{0.577}[/tex]

L = 5.199

Joe Summers buys a gas grill and accessories. The cost, including tax, amounts to $850.00. Joe finances the grill over 12 months after making a $150 down payment. The true annual Interest rate is 14%. What are Joe's monthly payments (principal plus Interest)?

To the nearest penny, c = $ Total of payments = amount financed + c = $ Total of payments = number of payments = monthly payment = $​

Answers

Answer:

"$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

Interest rate = 14 %

So, interest on $700 =

So, c = $98

Total payment = amount financed + c  = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

                                      =798 ÷ 12

                                      =$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!

PLZ GIVE BRAINLIEST AND PUSH THANKS BUTTON IM IN A BET ABOUT WHOEVER WINS GETS $50

Side lengths form a triangle that is similar to triangle ABC are 30, 21, 45 and this can be determined by using the given data.

Given :

Triangle ABC.AB = 10AC = 15BC = 7

The following steps can be used in order to determine the side lengths form a triangle that is similar to triangle ABC:

Step 1 - First determine the ratio of the length of AB and AC.

[tex]\rm \dfrac{AB }{AC} = \dfrac{10}{15}[/tex]    --- (1)

Step 2 - Now, determine the ratio of the length of AC and BC.

[tex]\rm \dfrac{AC }{BC} = \dfrac{15}{7}[/tex]  --- (2)

Step 3 - Determine the ratio of the length of BC and AB.

[tex]\rm \dfrac{AB }{BC} = \dfrac{10}{7}[/tex]   --- (3)

Step 4 - Now, check the ratio of the side lengths given in option A).

[tex]\dfrac{30}{21}=\dfrac{10}{7}[/tex]           (Similar to expression 3)

[tex]\dfrac{45}{21}=\dfrac{15}{7}[/tex]           (Similar to expression 2)
