I know that to be a USPS first class package, a package has to weigh 13 ounces or less. But my question is this: can a box be shipped as a first class package? I have a smaller sized item that I need to ship, but it s a little to big to fit comfortably in a padded envelope. And all of the first class packages that I ve seen have been in padded envelopes. Thanks!

I had a question about two tight end sets and who is an eligible receiver in this formation. I know that you have to have at least 7 players on the line of scrimmage or it s an illegal formation. You can have more than 7, but 7 is typical

So if I have a two tight end set, both tight ends are eligible receivers as long as the wide receivers on the outsides line up off the line, right? For example, say I have a tight end outside of each tackle, a receiver out wide on each side (but off the line) a QB and a back in the backfield, I have 5 eligible receivers? (both WRs, both tight ends and the RB)

But say for instance that the receiver split out wide right lines up on the line of scrimmage. This makes the tight end who s lined up on the line of scrimmage on the right side an ineligible receiver, right? I would have only 4 eligible receivers, and the said tight end would not be allowed to pass the line of scrimmage until after the ball is caught?

Sorry this is so long. Just wanting to clarify. Thanks!

This is definitely a dumb question, but where do you place a printed shipping label on a square box? I'd prefer not to place it on the top because that is where the flaps come together and I don't want to risk having the label accidentally ripped off. But will the package still be accepted by the USPS if I place the label on any of the four sides? Thanks!

Yesterday, I mailed a letter with the wrong type of street. For example, I mailed it to 123 Smith Ave. instead of 123 Smith Rd. Everything else is correct: the street number, the town and the zip code.

Will the letter still make it to the person or will it be returned to sender? Thanks!

A certain flight arrives on time 88% of the time. Suppose 142 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that:

A: exactly 123 flights are on time

B: at least 123 flights are on time

C: fewer than 132 flights are on time

D: between 132 and 134, inclusive are on time.

Also, is there a way to solve this on a ti-83 calculator? Thank you very much!!!!!!!

Clarinex-D is a medication whose purpose is to reduce the symptoms associated with a variety of allergies. In clinical trials of Clarinex-D, 5% of the patients in the study experienced insomnia as a side effect. Suppose a random sample of 20 Clarinex-D users is obtained and the number of patients who experienced insomnia is recorded.

a. Find the probability that exactly 3 experienced insomnia as a side effect.

b. Find the probability that 3 or fewer experienced insomnia as a side effect.

c. Find the probability that 3 or more experienced insomnia as a side effect.

d. Find the probability that between 1 and 4 patients, inclusive, experienced insomnia as a side efffect?

In the game of roulette, a player can place a $7 bet on the number 2 and have a 1/38 probability of winning. If the metal ball lands on 2, the player gets to keep the $7 and is rewarded $245. Otherwise, the player is awarded nothing and the casino takes the $7. What is the expected value of the game to the player? If you played the game 1,000 times, how much would you expect to lose?

The expected value is:
