Question

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

Answer 25

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)

Answer 26

@Skielerlucas04

Answer 27

this is confusing me lol

Answer 28

sorry

Answer 29

is that all one question?

Answer 30

yes

Answer 31

ohhh ok

Answer 32

Answer 33

thats just the picture ^

Answer 34

ik

Answer 35

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)

Answer 36

and theres tha questions lol^

Answer 37

sorry i tried to make it easier to read

Answer 38

ok the area of the circle is 7.07

Answer 39

ok but i need to now how you did it, because it wants me to explain my answer.

Answer 40

and the area of the square is 81

Answer 41

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

Answer 42

ok so thats part a?

Answer 43

yes

Answer 44

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

Answer 45

ok thank you so much

Answer 46

was that one or two questions

Answer 47

1

Answer 48

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)

Answer 49

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

Answer 50

thats for part B

Answer 51

sorry i was eating a pineapple

Answer 52

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%

Answer 53

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.

Answer 54

ok cool

Answer 55

is that it?

Answer 56

no, there is 2 more

Answer 57

can i pm u?

Answer 58

pm?

Answer 59

private message

Answer 60

oh yeah sure

how do you do that lol

Answer 62

just did

Answer 63

post the other ones

Answer 64

one at a time tho lol

Answer 65

ok

Answer 66

Jake tossed a paper cup 50 times and recorded how it landed. The table shows the results:

Answer 67

Position Open Side Up Closed Side Up Landing on Side
Number of Times Landed in Position 3 7 40

Answer 68

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.

Answer 69

sorry i sent it in pieces lol

Answer 70

can u send a pic of the table

Answer 71

it wont, it just sends it in word form

Answer 72

can u send it all in one piece?

Answer 73

yes give me a second

Answer 74

Jake tossed a paper cup 50 times and recorded how it landed. The table shows the results:


Position Open Side Up Closed Side Up Landing on Side
Number of Times Landed in Position 3 7 40


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.

Answer 75

LUCAS

Answer 76

what u do is take the number of times each position that it landed and divide it by 50 then multiply by 100

Answer 77

wait is that the answer or do you actually want me to do that

Answer 78

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

Answer 79

IS THAT THE ANSWER ORR

Answer 80

UM

Answer 81

caps xD

Answer 82

UM OK ILL SEND THE SECOND ONE YES OKAY GOOD

Answer 83

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.

Answer 84

@Skielerlucas04 ^^^

Answer 85

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.

Answer 86

ok is that the answer for the one i just sent you?

Answer 87

yes

Answer 88

did u get the other one

Answer 89

i was showing u how do it

Answer 90

no lol

Answer 91

just give me the answer its easier

Answer 92

i ggave u one answer

Answer 93

6%

Answer 94

can you give me the rest

Answer 95

oh my god my family is walking out the door

Answer 96

the 7 divided by 50= 0.14x100=14% for close side up

Answer 97

then 80% for the last one
