    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.

  14. 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 step-by-step explanation and a problem-solving 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 Pac-Man. 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 Pac-Man 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 open-courseware 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.

    Divide by using long division.

    • ANSWER:
      long division
      divide x [from the denominator]
      into the leading term to get the divisor
      then see what the -4 generates

      2x^3-3x^2-18x-8

      2x^3/x=2x^2
      2x^2*(x-4)=2x^3-8x^2

      subtract
      5x^2-18x-8

      5x^2/x=5x
      5x*(x-4)=5x^2-20x

      subtract
      2x-8

      2x/x=2
      2*(x-4)=2x-8

      leaves zero

      collect the divisors

    2. Lies are a waste of time

    • ANSWER:
      1. 8x = 10x + 70
      -2x = 70
      x = -35

      2. 8m -4m -16 = 0
      4m -16 = 0
      4m = 16
      m = 4

      3. -12x + 24 = 6 +4x
      18 = 16x
      x = 9/8

  35. QUESTION:
    Does anyone know where me and my hubby can find a free online site for math brain teasers??
    We have been looking around but, all we come up with is sudoku, word brain teasers, and word math problems. We dont mind word math problems, but we dont want all of them to be word. We want a site where you can visually have about 30-100 ( or more ) questions to answer. Mostly college algebra and up. Thats where we last left off. LOL Thanks everyone!!

    • ANSWER:
      It is not that difficult to make your own puzzles.
      If you really need them, look through previous Mathematics Contests. I have always found them intriguing to do.

    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)

    "Over the past hundred or so years, the Earth's population has grown at a very predictable rate. Every 30 years, the population has doubled. Assuming the Earth's population has always increased in this fashion, when did people first appear?"
    The time when people first appeared began with two people.

    OHHH! i didnt tell the FIRST FIVE PEOPLE who aswered this: (very important)

    world's population: 6,692,088,500
    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 half-life 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...

  42. 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? Explain

    an 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.

    1. Directions for Problems 1-5: 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 false

    always 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 false

    always true

    never true; if m = 2 and n = 7, then the statement is false

    4. Directions for Problems 1-5: 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 1/1

      -5 > -1
      -1/5 is greater than -1/1

      2. 2x^2 – 12x + 18 = 0
      2(x^2-6x+9) = 0
      2(x-3)^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).

    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

    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
      x-153x/2304
