A plan for an executive travelers' club has been developed by an airline on the premise that 5% of its current customers would q

ualify for membership. A random sample of 500 customers yielded 45 who would qualify. (a) Using this data, test at level 0.01 the null hypothesis that the company's premise is correct against the alternative that it is not correct. State the appropriate null and alternative hypotheses. H0: p ≠ 0.05 Ha: p < 0.05 H0: p = 0.05 Ha: p > 0.05 H0: p = 0.05 Ha: p ≠ 0.05 H0: p ≠ 0.05 Ha: p = 0.05 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P-value = State the conclusion in the problem context. Reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Reject the null hypothesis. There is sufficient evidence to conclude that the company's premise is incorrect.

1. Consider the rational numbers 4/13 and 3/10.
Murljashka [212]

A)4/13 would be the larger number since if you were to try to add them, 4/13 = 40/130 and 3/10 = 39/130, 40/130 > 39/130

B) A rational number between them would be 39.5/130.

The sum of three numbers is 20. The sum of twice the first number, 5 times the second
Fed [463]

Answer:

well this is required for ur knowledge and ur experience but i could give u an example if u want

last week i had lied to my step mother about something that was small, she found out emediatly that i was lying and got mad. she asked me why do i lie to her so much and i couldnt answer cuz i didnt know. i lied to her many times  before and did some other stuff to her such as stealing and lying about important stuff. yesterday when she finally wasnt mad at me we talked long and hard and she told me that each time i lied or stole from her it broke alittle bit of her trust in me, she asked me if it was cuz i just didnt like her and i told her no and that i saw her as a family memember  but she told me she didnt believe me and that she cant believe a thing i say due to how much i lied to her. there was a lot of tears after that long talk and after i calmed down i did some stuff and then started thinking of reasons why i did the things i did. then i started thinking of how i could of fixed it. a way i could of fixed the issue before it was even an issue was i could of not lied nor stole from her, i could of told her how i felt instead of holding my emotions in. id love to fix what i lost but its not possible. a way i could fix the issue i have rn is try not to lie and try to convince her to trust me. something i want to take back during our talk? not saying anything at all.

now im not saying any of that was true but its a good example of what to say during this essay you could use ur own words and ur own problem to explain how you could fix,repair and all that other stuff. just use ur own story for the essay.  in ur own words and story try to answer all the questions asked.

If you had to relive that situation all over again, how would you fix the fight or keep it from turning into one?

Think about the following questions and then write several paragraphs in response: When did the fight occur, and what was it about?

Who was at fault—you, the other person, or both of you?

Why do you think it ended poorly?

In general, what would you have done differently?

What could you have said differently that would have let the other person know you were listening?

If you could take back something you said during the fight, what would it be?

What do you wish you would have said during that fight?

Did the fight result in your not being friends or not getting along with that person anymore?

Would you want repair your relationship with this person again?

If so, what are some possible ways to fix the damage?

focus on those questions when doing ur work and explain in detail how u would of fixed it or made it better :)

hope this helps and sorry it was so long anyways ik im asking a lot but if i helped can i get brainliest?

Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (2, -1)
jek_recluse [69]

Answer:

The equation of the line is 2x - 3y = 7 ⇒ answer A

Step-by-step explanation:

* Lets revise the relation between the parallel lines

- If two lines are equal then their slopes are equal

- We can make an equation of a line by using its slope and

 a point on the line

- If the slope of the line is m and passing through the point (x1 , y1),

 then we can use this form [y - y1]/[x - x1] = m to find the equation

* Lets solve the problem

- The line is parallel to the line 2x - 3y = 5

∴ the slope of the line = the slope of the line 2x - 3y = 5

- Rearrange the terms of the equation to be in the form

  y = mx + c to find the slope of it

∵ 2x - 3y = 5 ⇒ subtract 2x from both sides

∴ -3y = 5 - 2x ⇒ divide two sides by -3

∴ y = 5/-3 - 2x/-3 ⇒ y = 2/3 x - 5/3

∴ The slop of the line is 2/3

∵ The line passes through point (2 , -1)

* Lets use the rule to find the equation of the line

∵ y - (-1)/x - 2 = 2/3

∴ y + 1/x - 2 = 2/3 ⇒ by using cross multiplication

∴ 3(y + 1) = 2(x - 2) ⇒ open the brackets

∴ 3y + 3 = 2x - 4 ⇒ put x an d y in one side

∴ 2x - 3y = 3 + 4

∴ 2x - 3y = 7

* The equation of the line is 2x - 3y = 7
