I have no idea how to do this problem, so if you can walk me through step by step, it would be very much appreciated!

I wonder how Ghost Hunters,.TAPS...and all those other groups go to foreign countries and understand what the ghosts are saying. Do they take an interpreter with them? Or do all ghosts speak English? (I'm not sure I should have wasted 5 pts. on a silly question like this. I just want to "play" too!!)

Those who have some background information, or just know enough...
A suggestion of a tenth planet was brought up. However, it seems in this day & age. we couldn't just declare anything a planet, but there was never any official meaning for a planet, or for celestial bodies in general, so how would we know how to tell?,

How do you feel about the events that transpired?, How do you feel about the decision and scientific definition they came up with, does it make sense?, Do you approve of the way they handled the situation and the method they used in reaching their solution? (voting=politics=not science)
Do you think anyone will be affected by this?, who will be affected the most?
Why do you think it's caused as much of a controversy as it has?, what exactly is so special about Pluto anyway (once deemed "the plucky little planet that could)

Okay, that's not an essay prompt, I just want responses, & i'm trying to lead you into your answer...
Thanks!!!

The starting salaries of a random sample of three students who graduated from North Carolina State University last year with majors in the mathematics sciences are $45,000, $35,000, and $55,000.

a. Find a point estimate of the population mean of the starting salaries of all math science graduates at that university last year.

b. There is a margin of error of $24,800 for a 95% confidence interval for the population mean starting income. Construct that interval.

c. Use this example to explain why a point estimate alone is usually insufficient for a statistical inference.

*Notes:
A point estimate is a single number that is our "best guess" for the parameter.

An interval estimate is an interval of numbers within which the parameter value is believed to fall.

A confidence interval is an interval containing the most believable values for a parameter. This is a number chosen to be close to 1, most commonly 0.95.

So I figured out that the 3 cubic roots are -2, 1+i(square root of 3) and 1-i(square root of 3)

So how do i verify that 1+i(square root of 3) multiplied by 3 is -8?
Is it?

1)what may cause a ball to miss the target?
2)you probably noticed that the range of the ball increases in direct proportion to the speed at which it left the ramp. the speed depends on the release point of the ball on the ramp. what roles do you think air resistance had in this experiment?

3)should the height of the can be taken into account when measuring the vertical distances h?

Can anyone explain space or time as entities within themselves? Are they not simply measures of 'how much?' What is the definition of space? What is the definition of time?
