Let's call the number we're looking for $y$ . We know that $y$ is twice as much as $x$ .

Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.

So, in order to obtain $y$ , you have to multply $x$ by 2. In formula, you have

$y = 2\cdot x$ or simply $y = 2x$

Why is volume of a cone is written in cubic units

frutty [35]

Answer:

The formula for the volume of a cone is 1/3 Bh. This means 1/3 the Area of the base times the height. You can calculate the area by multiply length and width. Area is two-dimensional. Multiplying height by it adds another dimension. When writing area, we say units squared. When writing volume, we say units cubed, because it is three dimensional.

g In a one-tail hypothesis test where you reject H0 only in the lower tail, what is the p-value if Z STAT

zepelin [54]

Answer:

The P-value is 0.0166.

Step-by-step explanation:

<u>The complete question is:</u> In a one-tail hypothesis test where you reject H0 only in the lower tail, what is the p-value if ZSTAT = -2.13.

We are given that the z-statistics value is -2.13 and we have to find the p-value.

Now, the p-value of the test statistics is given by the following condition;

P-value = P(Z < -2.13) = 1 - P(Z $\leq$ 2.13)

= 1 - 0.9834 = <u>0.0166</u>

Assuming that the level of significance is 0.10 or 10%.

The decision rule for rejecting the null hypothesis based on p-value is given by;

If the P-value of the test statistics is less than the level of significance, then we have sufficient evidence to reject the null hypothesis.

If the P-value of the test statistics is more than the level of significance, then we have insufficient evidence to reject the null hypothesis.

Here, the P-value is more than the level of significance as 0.0166 > 0.10, so we have insufficient evidence to reject the null hypothesis, so we fail to reject the null hypothesis.

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?
