Consider the experiment where you flip a fair coin 4 times and you are interested in the number of heads that appear. From the website http://www.socr.ucla.edu/ go to DISTRIBUTIONS → [SOCR DISTRIBUTIONS] → BINOMIAL DISTRIBUTION. Select the appropriate “success probability” for this experiment.(a) Define the random variable of interest X.
(b) Use the applet to determine the probability that we observe exactly 2 heads.
(c) Now draw a tree diagram for the sample space, and determine, by hand, the probability of observing exactly 2 heads. Does this agree with your answer in 1(b)?
(d) What is the probability that we do not observe 2 heads?
(e) Use the applet to determine the mean and variance of X.
3. Using the same applet as in question 1, now adjust the number of trials to 16.
(a) What is the probability that we observe exactly 10 heads?
(b) Go to: http://www.pstat.ucsb.edu/faculty/gatto/binomial.pdf. Use this table to determine the probability of observing exactly 10 heads. Does this agree with your answer in 2(a)?

QUESTION:
I really need help with these math problems?!?
I'm taking a course in math in college but it's REALLY harder than I expected. It's online and I can't get in touch with the professor. The book I have is huge and I have to answer math problems that the book isn't even touching, like the class expects me to know it already but I honestly haven't touched math in a year. I need help with this question.A square barn measures 14 meters on each side. A goat is tethered outside by a rope that is attached to one corner of the barn:
a. Suppose that the length of the rope is 8 meters. On how many square meters of land is the goat able to graze? What shape is formed?
b. Suppose that the rope is made twice as long as in part a. On how many square meters of land is the goat now able to graze?
c. Lastly, an addition to the barn was built making it rectangular with dimensions 14 meters by 20 meters and extended the length of the rope to 24 meters, on how many square meters of land is the goat now able to graze?
The instructions say I have to give a stepbystep explanation and a problemsolving strategy I used. Please help and also, where can I go online to help me with learning math for free.

ANSWER:
Think simple...don't make this harder than it is. It would be best to draw this on paper. Picture the barn...14m each side. The rope is 8m at one of the corners. That means the goat can make a circle that has a radius of 8m, right? It would be a full circle, but the barn is in the way...it blocks 1/4 of the circle...making the circle look like PacMan. Use the formula for the area of a circle, then multiply by 0.75 or divide by 4 and multiply by 3 or whatever method makes sense to find 3/4 of the circle's area (area of a circle = pi * radius^2...ref: http://www.mathgoodies.com/lessons/vol2/circle_area.html). That takes care of part (a).To do parts (b) and (c), use the same ideas. For (b), the circle is slightly bigger than the sides of the barn, so it will be like a PacMan with "lips." By that I mean it will be a big 3/4 circle just like (a), but you will have another 1/4 circle of radius 2m at each of the sides where the rope is longer than the barn sides. Summary...3/4 the area of a circle of radius 16m, then add 1/4 area of a circle of radius 2m (do that 1/4 part 2 times...one for each of the barn sides),
Hopefully you're able to see how to get part (c) with those examples...same ideas, just draw it out and break it into simple shapes.
As far as free math help, there are tons of places, but if you like a high $ education for free, try the MIT opencourseware site http://ocw.mit.edu/index.htm where you can watch the same lectures for a lot of classes just as if you were in the class. Good luck.

Let W be the wrapping function and suppose f is the real function defined by:
f(theta) = d(W(0), W(pi/2 + theta)) / d(W(0), W(pi/2  theta))Find domain f
Determine whether f is even, odd, or neither
Find the zeros of f
Compute f(theta) in terms of cosine theta and sine theta and simplify the result until it is radical free.I hope this is readable and understandable. I don't have any of the symbols so I had to write out the word. I would appreciate it if only people who are able to answer this problem would comment. Please no "Why don't you do this yourself" comments, I am aware that I should be doing this myself but I do not understand how to do it, and all help is appreciated. Thanks.

My teacher isn't answering, but I assume that d is a function, if that helps.
ANSWER:
I will give you two hints:1. Wrapping function W(theta) gives you the point on the Cartesian graph that has coordinates (cos(theta), sin(theta))
2. In your equation 'd' means the distance between the two points (the function's arguments)

population increases 2.83 people per second
ANSWER:
According to PopClock, the current population of the world is 6,575,124,463 people. Wow...If you assume the population doubles every 30 years, then that would mean the population, in reverse time, has a halflife of thirty years. The formula for the number of generations is simply the log base 2 of the current population. The total time is then 30 years times that number... it's gonna be stupidly low.
computing... ding!
It's around 32... 22 is if you use the natural log, but you want the base 2 log. Multiply that by 30 and you have a grand total of 960 years of human history. Mmmmmkay...


QUESTION:
Math Problem! How many free pizza slices were given away? How many cups of soda were given away?
Info: Every Monday, at Capri Pizza, lucky customers can get free slices of pizza and free soda. Every 10th customer gets a free plain slice of pizza and every 12th customer gets a free cup of soda. On the first Monday of March, Capri Pizza had 211 customers.How do i do this problem and these:
b) When Jackie came into Capri Pizza, the owner told her that she was the first person to get both free items (the free slice of pizza and the free soda). What number customer must Jackie have been? How many other customers (from the 211 customers) would also get both free items? Explain.
c) Suppose that the owner also decides to give away free bags of potato chips to every 7th customer. Would any of the 211 customers be lucky enough to get all three free items? Explainan answer to any of these questions is good

ANSWER:
floor(211 / 10) = 21, so there were 21 customers getting free pizza.
floor(211 / 12) = 17, so there were 17 free sodas.The least common multiple of 10 and 12 is 60, so Jackie was the 60th customer of the day. Since floor(211/60) = 3, there would be two more customers that day getting both items free.
If potato chips are thrown into the mix, no customers that day would get all three items free, because the least common multiple of 10, 12, and 7 is 420. They would have to get about twice as many customers to end up hitting that number.

math. help. please answer!!!!! i dont get it so feel free to explain, but give your answers too :]?
1. Directions for Problems 15: Tell whether each statement is sometimes, always, or never true. For sometimes or never true, choose the answer that provides the correct counterexample.If a and b are nonzero real numbers and a > b, then 1/a > 1/b
2. If 2x^2 – 12x + 18 = 0, then x = 3. (The domain is all real numbers.) (Points: 1)
sometimes true; if x = –3, the statement is falsealways true
never true; if x = –3, the statement is false
3. If m and n are prime numbers, then m + n is also a prime number. (Points: 1)
sometimes true; if m = 3 and n = 11, then the statement is falsealways true
never true; if m = 2 and n = 7, then the statement is false
4. Directions for Problems 15: Tell whether each statement is sometimes, always, or never true. For sometimes or never true, choose the answer that provides the correct counterexample.
If 3x + 7 < 29, then x is an integer.

ANSWER:
1. Sometimes.
5 > 1
1/5 is not greater than 1/15 > 1
1/5 is greater than 1/12. 2x^2 – 12x + 18 = 0
2(x^26x+9) = 0
2(x3)^2 = 0
x = 3
This is equation is only true when x = 3.
That means if x does NOT equal 3, then the equation is false.3. If m = 3 and n = 11, then
m+n = 3+11 = 14 which is not prime.
Sometimes true. If m = 2 and n = 5, then m+n = 2+5 = 7 which is prime.4. Sometimes.
x = 0 is a solution (and 0 is an integer).
x = 1/2 is a solution (and 1/2 is not an integer).

QUESTION:
A few general math problems, need some help?
Basically, these questions are always giving me problems. They're a mix between probability, geometry, etc.. If you could help out, that would mean alot. I honestly wouldn't be asking if I could figure them out myself. Basically, I need to know how to figure each problem out. If you wish to provide the answer, feel free. If you could explain what I need to do in the BEST detail possible I would appreciate it. Thanks1.

Math Book Answers?
I need to know if there are any websites out there that will provide me with free answers for the Connected Mathematics text books?
Im having a really hard time figuring out some of the problems and I don't want to show up with nothing done. I don't want "advice" i just want to know of any websites.
ANSWER:
I taught with Connected Mathematics last year (I hated it).Their website is www.connectedmath.msu.edu.
hotmath.com claims to have answers for CMP.
The questions are difficult and very complex. Good luck with that. You think it is difficult to learn with it, it is certainly hard to TEACH it.


QUESTION:
Offering free math tutoring, where should i go?
I want to stay in practice with my math skills this summer and I don't just want to do practice problems on my own. I've decided that tutoring people for free will help several people all at once.As much as I like Yahoo! Answers I absolutely cannot do math in text format.
Does anyone know of a good website for like a streaming whiteboard kind of feel? They draw the problem and I can show them how to solve it like that. I'm not looking for a job. I won't be spending hours on there helping random people. I want a place that I can just log on to and help people and leave whenever I want.
Does a place like this exist?

QUESTION:
Math Problem please! Homework! free 10 pts.?
ROPES #2 The Class Picnic(Adv. Math)
Last year, Mrs. Reynolds’ class invited the families of her students to come and join in the fun during their annual picnic at Lake Konocktee. Mrs. Reynolds needed to get a white ticket for each adult, a green ticket for each boy, and a yellow ticket for each girl. The 60 adults mostly sat in the shade watching the kids play. The boys, who made up one third of the total people there, generally played in the lake. The girls only made up one sixth of the total number of people at the picnic; most of them played volleyball. How many yellow tickets did Mrs. Reynolds need to get?There's the problem, I need to know how you figured out your answer and it worked out a bit.. just explain how you got to your answer.
No, 60 is the number of ADULTS but there are more than 60 since the boys and girls also make up the TOTAL, not just the adults.
ANSWER:
that's so easy, she needs 20 yellow tickets because she already has 60 adults, and has 1/2 worth of boys and girls together, meaning that 60 is half, so one sixth would be the 20 tickets, and she would also need 40 green tickets, just in case you wanted to know

5.Mom baked a cake for the entire family. Dad ate 1/6, Brother ate 1/6 of what was left. Sister ate 1/4 of what was left. Spot the dog ate 1/3 of what was left. Baby sister ate 1/2 of
5 CONTINUED!
Baby sister ate 1/2 of what was left. How much of the original cake was left for mom to eat?Who ate the most of the cake?
ANSWER:
5) Let x be the cake.
Dad = x/16
Brother = (1/6)x/16=x/96
Sister = (1/4)(x/96) = x/ 384
Spot = (1/3)(x/384) = x/ 1152
Baby sister = (1/2)(x/1152)= x/ 2304
Cake left = x[x/16+x/384+x/1152+x/2304]
x[144x+6x+2x+1]/2304
x153x/2304
2151/2304 of cake left
