A spinner has six sections of equal shape and size. Each section is either black or white. The table shows the result of an experiment when the spinner was spun 90 times: Result of Spin Black White Number of Spins 72 18 Based on the datawhich of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner? The spinner is equally likely to land on black or whit The spinner is 4 times more likely to land on whit The spinner is 4 times more likely to land on black The information cannot be concluded from the data table

A square is shown with sides labeled 9. A shaded circle is shown in the center of the square. The diameter of the circle is 3.

Part A: Is the probability of hitting the black circle inside the target closer to 0 or 1? Explain your answer. (5 points) Part B: Is the probability of hitting the white portion of the target closer to 0 or 1? Explain your answer. (5 points)

and theres tha questions lol^
anonymous
  • anonymous
sorry i tried to make it easier to read
anonymous
  • anonymous
ok the area of the circle is 7.07
anonymous
  • anonymous
ok but i need to now how you did it, because it wants me to explain my answer.
anonymous
  • anonymous
and the area of the square is 81
anonymous
  • anonymous
the probability of hitting inside the target would be closer to 0 because there is a higher total area in the square and the circle only covers 7.07 total area of the square out of the 81 total area that the square has
anonymous
  • anonymous
ok so thats part a?
anonymous
  • anonymous
yes
anonymous
  • anonymous
the probability of hitting the white is closer to 1 because the the black circle only takes up 7.07 of the area of the square so the square (white part) has a higher probability of getting hit
anonymous
  • anonymous
ok thank you so much

was that one or two questions

Isla flipped a coin 30 times. The coin landed heads up 9 times and tails up 21 times. Part A: Based on the results, what is the experimental probability of the coin landing heads up? Show your work. (5 points) Part B: What is the theoretical probability of the coin landing heads up? Show your work. (5 points)
anonymous
  • anonymous
based on theoretical probability the coin should land heads up 15 times since there are two sides to the coin and since she flipped it 30 times you would usually have the amount of heads and tails split even
anonymous
  • anonymous
thats for part B
anonymous
  • anonymous
sorry i was eating a pineapple
anonymous
  • anonymous
based on the results, there is a 30% chance that she will get heads because from the results you would take 9 and divide that by 30 and get .3 then multiply that by 100 and that would give you 30%
anonymous
  • anonymous
ok thank you, and since it all has to be typed out my teacher has to grade it instead so it might take a few days for the results to come in, but ill let you know what i get as soon as i do.
anonymous

ok cool

Based on the table, determine the experimental probability of each outcome (landing open side up, landing closed side up, and landing on its side). Show your work.
anonymous

sorry i sent it in pieces lol
anonymous
  • anonymous
can u send a pic of the table
anonymous
  • anonymous
it wont, it just sends it in word form

can u send it all in one piece?

LUCAS
anonymous
  • anonymous
what u do is take the number of times each position that it landed and divide it by 50 then multiply by 100
anonymous
  • anonymous
wait is that the answer or do you actually want me to do that
anonymous
  • anonymous
for example 3 divided by 50=0.06 then multiply that by 100 and u get 6% for the probabitity of it landing open side up position
anonymous
  • anonymous
IS THAT THE ANSWER ORR
anonymous
  • anonymous
UM
anonymous
  • anonymous
caps xD
anonymous

UM OK ILL SEND THE SECOND ONE YES OKAY GOOD

Mark spins a penny 100 times and it lands head side up 41 times. Explain why Mark's experimental probability may be different from the theoretical probability of spinning a coin.
anonymous
  • anonymous
anonymous
  • anonymous
because the theoretical probability would say that the amount of times the coin lands on heads would be very close if not the same as the amount of times it would land on tails. so since he is spinning it randomly, he is going to get a random number and it could be way off from the theoretical probability.
anonymous
  • anonymous
ok is that the answer for the one i just sent you?
anonymous
  • anonymous
yes
anonymous
  • anonymous
did u get the other one
anonymous
  • anonymous
i was showing u how do it
anonymous
  • anonymous
no lol
anonymous
  • anonymous
just give me the answer its easier
anonymous
  • anonymous
i ggave u one answer
anonymous
  • anonymous
6%
anonymous
  • anonymous
can you give me the rest
anonymous
  • anonymous
oh my god my family is walking out the door
anonymous
  • anonymous
the 7 divided by 50= 0.14x100=14% for close side up
anonymous
  • anonymous
then 80% for the last one
anonymous
  • anonymous
ill convince them to stay home
anonymous
  • anonymous
the on its side position
anonymous
  • anonymous
thats all of them
anonymous
  • anonymous
can you say it all in one message its getting confusing
anonymous
  • anonymous
open side up: 3 / 50 = 0.06 x 100 = 6% closed side up: 7 / 50 = 0.14 x 100 = 14% landing on its side: 40 / 50 = 0.8 x 100 = 80%
anonymous
  • anonymous
ur lucky i like you :P
anonymous
  • anonymous
ok thanks ill submit the test now. thanks again
anonymous
  • anonymous
haha that is so sweet, i couldnt thank you more i promise ill do whatever to make it up to you :D
anonymous
  • anonymous
can i kik u now or can u not use ur phone?
anonymous
  • anonymous
yeah you can kik me
anonymous
  • anonymous
ok :D
