I usually avoid asking these type of questions to the best of my ability, but I figured there's no harm in asking.

My boyfriend is 19, I'm 18. We've been really good friends for the past 2 or 3 years. We decided a couple months ago to try dating. And so far, so good. The only thing I have an issue with is that I'm a virgin, and he's definitely been around the block a couple times with a good handful of girls. When we were friends, it didn't bug me but now that we're dating, it gets to me a little.

Do you think it's normal for this to make me feel a little uneasy? I hate this high school drama boyfriend issues crap. But I just want to know if it's ok to be a tad upset or what you think I should do about it.

I showed it to my mom, too, but she doesn't understand it either.

"Describe the bio-psychosocial view of successful aging. Be sure to give examples of biological, psychological and social factors that facilitate a positive old age."

Can someone please translate this into plain English for me? I am trying to understand the praise that Hamlet has for Horatio but I can't seem to grasp it.

for thou hast been

As one, in suffering all, that suffers nothing,

A man that fortune's buffets and rewards

Hast ta'en with equal thanks: and blest are those

Whose blood and judgment are so well commingled,

That they are not a pipe for fortune's finger

To sound what stop she please. Give me that man

That is not passion's slave, and I will wear him

In my heart's core, ay, in my heart of heart,

As I do thee.

I need homework help! No, I am not cheating. I have provided my answers below. I just need to know if I did them right. And if I didn't, can you tell me what I did wrong? Please help. Thank you.

I. The expected value of a geometric random variable is determined by the formula (1-p)p.

II. If X is a geometric random variable and the probability of success is .85, then the probability distribution of X will be skewed left, since .85 is closer to 1 than 0.

A) I only

B) II only

C) III only

D) I and II only

3. B-False.

4. A- (Well, B is technically a right answer too because the z score is for both negative and positive) C and D had too high of a probability.

I am writing an essay for my AP English class about Hamlet. What do you think are some motifs in the second and third acts? There is no right or wrong answer, as there are endless possibilities. For example, I think that one of the most obvious motifs in the second act is confusion. What do you think?

AP Statistics, I would appreciate the help.

Hey! So here is the situation: I am 18 year old high school senior, I am living at home, and I am jobless. About a week ago, my mom informed me that my parents were going to quit paying for things like gas, food, clothes, etc. I am totally fine with that, in fact, I would love to have a job. However, my parents still will not allow me to get a job because, according to them, SCHOOL is my job (I have like a 3.9 GPA overall).

A little hypocrytical on their part considering they want me to pay for my own stuff yet won't allow me to get a job.

I require not much. I could make do with 200 a month (most of that for fuel.)

What I am asking of YOU, fellow YouTube Answerers, is how can I make an income without having a job? I was maybe looking at Associated Content for writing articles because I love to write and I'm actually good at it. Anyone have any experience with that or any other ideas?

Please keep ideas LEGAL. I don't really feel like going to jail for drug dealing or prostitution (sorry, that was a bad joke on my part.)

If it is not a total loss, but the damage is more than $2000, then $1500 will be paid. Nothing will be paid for damage costing $2000 or less and of course nothing is paid out if there is no damage.

I'm an 18 year old girl. I just want a steady boyfreind (yea yea, I know I'm young, but come on we all know how it feels to have someone to love). However, it seems like the only type of guys that I can attract are horny ones that want a "dip and run" even though they are aware that I am a virgin and by no means slutty, nor do I wear revealing clothing. I'm really into music, guitar, hiphop and tap dance, and volunteering, pretty smart, and I love hiking. My closest circle of friends are all guys and they all refer to me as either their little sister or brother. I ask them if I'm just not attractive for a boyfriend but they all claim that I'm hot and a total sweetheart and anyone would be lucky to have me.

Sorry, I'm just kind of ranting now.

What I'm asking of you, am I just not girlfriend material? Picture available upon request if you either leave your email address, cell number, or IM ID or something.

So I am in AP Statistics and it is torture. I am doing this assignment, it has 7 questions that are all alike, and I have no idea what to do. I am posting the first question so if you could please explain what to do so I can do the rest of them, that would be awesome! Thank you so much.

Glaucoma is a disease of the eye that is manifested by high intraocular pressure. The distribution of intraocular pressure in the general population is approximately normal with mean 16 mm Hg and standard deviation 3.2 mm Hg. If the normal range for intraocular pressure is between 10 and 22 mm Hg, than what proportion of the general population would fall within this range?

2. An experimenter wishes to test whether or not two types of fish food (a standard fish food and a new product) work equally well at producing fish of equal weight after a 2-month feeding program. The experimenter has 2 identical fish tanks (1 & 2) to put fish in and is considering how to assign the 40 tagged fish to the tanks. To properly assign the fish, one step would be to:

A) put all the odd tagged numbered fish in one tank, the even in the other, and give the standard food type to the odd numbered ones

B) obtain pairs of fish whose weights are virtually equal at the start of the experiment and randomly assign one to the group tank 1, the other to tank 2 with the feed assigned at random to the tanks.

C) to proceed as in as in (b), but put the heavier of the pair into tank 2.

D) assign the fish at random to the two tanks and give the standard feed to tank 1.

E) not to proceed as in (b) because using the initial weight in (b) is a non-random process.Use the initial length of the fish instead.
