My little brother set it up earlier and flew it just fine, but after a while one motor quit working. I did some research and downloaded betaflight. We hooked it up to the drone and now nothing s working. After several YouTube videos, here s what I ve tried:

Reset the controller s connection to the receiver (Taranis QX7). Its green light is flashing, but I think that connection s the problem somehow

My little brother thinks it s because when I opened betaflight, I clicked "reset settings" without backing it up. Was that the problem?

I set it up to UART 1. I don t know if that s correct.

Under "configuration," I set "receiver" to "IBUS"

When I go to "receiver" and play with the Taranis, none of the meters move like they re supposed to.

Is there any other way to troubleshoot this? I m a noob at drones.

I know my transmission s out, I m wondering the cost

and whether it has to be fixed or replaced. I m sure you have to see it to know for sure, but just a guess would be awesome.

It s a 2008 Toyota RAV4. When I put it in reverse, sometimes it will reverse for a bit. When I put it in drive, it sounds like it s trying to find the gear and it is grinding on it repeatedly. Sometimes it does that when I m trying to put it in reverse as well.

I m assuming I have to replace it, and I was guessing around $2,500. Am I in the right neighborhood there?

You randomly select a piece of fruit and then return it to the basket. Then you randomly select another piece of fruit. The first piece of fruit is an apple and the second piece is a peach. Find the probability.

So 5/12 *7/12, right? Do you times them together?

That s all I really need, but we re doing law of sines. The triangle is asymmetrical and not a right angle.

Angle A = 55 degrees

Side a = 7 (it s opposite the angle)

Angle B is what we re trying to know.

Side B = 9

So I set it up like this:

Sin55 degrees/7=sinB/9

Cross multiply, get to about

sinB=1.053

But when I plug in the inverse sin of 1.053 it s an error. Am I doing something wrong?

How in the heck do I get there?

Miss Smithson's SAGE test scores are normally distributed with a mean of 238 and a standard deviation of 32. What is the probability that one of her students will score between a 174 and 270?

I need to know the answer and how to figure it out.

Do they have a yearly fee or anything?

Otherwise, how do authors and/or publishing companies make money? Why doesn't everyone just go to the library?

Honest question here for a school assignment.

It's a hypothetical,

There's a man that starts a company based on the "first-sale doctrine," saying if he bought the books he could copy e-books and then resell them.

I was assigned to make the argument that he COULD do this. Super difficult.

My team met, and the section I agreed to take was how iTunes and other models like this work.

Is there any website that has like a "pay-for-subscription" thing and you get to use all their books, movies or music?

Or is there anything within the licensing laws that you could twist and make an argument for the bookstore owner?

Or any help at all? I've been reading a ton of legal articles about iTunes and Amazon, but none of them are relevant... that or they completely argue against my topic.

Any help at all? I'm three hours into this assignment and no closer to finishing it.

Currently company XYZ has a $1000 face value bond that matures in 10 years with an annual coupon rate of 6%. The bond is priced to yield 8% per year. What is the price of the bond? Input your answer without sign (no - or + signs) and without comma. Round to the nearest cent.

I'm trying to create a Jeopardy board in PowerPoint. I want it to show the points on one side and the question on the back (it's an answer because of the Jeopardy format, but I digress).

How do I do that?

I don't know what exactly it's called. For work, if you're connected to the internet via the business's secure server, you have access to a M-drive account.

I have connected to it before on my Mac, but my work computer is a windows.

How do I connect to this drive? TIA

44. Referring to the study in problem 42, suppose we wanted to plan a similar study with just female seniors. We want to have a margin of error of 25 with 95% confidence. What is the sample size needed to achieve this margin of error? Assume that the standard deviation for all female seniors is σ = 100.

(a) 8 (c) 62 (e) 122 (b) 61 (d) 87

I can NOT figure this out.

A company asserts that 80% of the customers who purchase its special lawn mower wil have no repairs during the first two years of ownership. Your personal study of 100 randomly selected ownders found 70 lasted the first two years without repair expenses. Can you use the standard Normal table to compute the probability that 70% or fewer in the sample lasted the two years without repair expenses? Why or why not?

(a) Yes, because the smaple size is greater than 30 and the Central Limit Theorem applies.

(b) Yes, because both of the following are met: np ≥ 10, n(1 − p) ≥ 10.

(c) No, because the sample size is less than 30 (so the Central Limit Theorem does not apply).

(d) No, because both of the following are not met: np ≥ 10, n(1 − p) ≥ 10.

Here's my problem. I know that it's either (b) or (d) because those are the rules for being able to compute that probability. But in order to know if the conditions are met or not, I need to find p.

The way to find p is using the table and finding the z-score.

The formula for z-score is x-U0/(sigma/sqrtn). I don't have the sigma/standard deviation. Even if I use the formula for t it doesn't work because I don't have the s or standard deviation.

How in the heck do I solve this?

If we were to test the hypotheses H0 : p = 0.7 versus Ha : p > 0.7 using sample results of pˆ = 0.80 from a sample of size 100, what is the value we should use for the standard deviation of the sampling distribution of pˆ in the test statistic?

(a) 0.0016 (b) 0.0021

(c) 0.0400 (d) 0.0458

The answer is D, but I don't know why. Is there a simple formula I don't know or something? 10 points to whomever walks me through this :).

4. Suppose you want to estimate the proportion of voters who will vote for George Smith, a candidate for state representative. How many should you sample in order to estimate p with a margin of error of 0.05 (5%) and 95% confidence?

(a) 1537 (c) 97 (e) 40 (b) 385 (d) 73

The answer is B. I have no idea why. How do you solve this? TIA
