Someone a spinner has five sectors of equal size. the sectors are labeled 1, 2, 3, 4, and 5. the spinner is spun twice. x is the number of times an odd number is spun. drag each bar on the horizontal axis to the correct location to create a probability distribution for x.

Because the sectors are of equal size, each sector has the same probability of happening.
So for every number, you have a probability of 0.2 of it appearing.

Because you have three odd numbers, the probability to land on an odd number on each spin is 0.6. You can also say that the probability to not have an odd number is 0.4.

So what is the probability to have 0 odd number in two spins?
$0.4 \times 0.4 = 0.16$
What is the probability to have 1 odd number in two spins? You can have one odd number on the first or one odd on the second spin, that is why we add the probabilities.
$0.6 \times 0.4 + 0.4 \times 0.6 = 0.24 + 0.24 = 0.48$
What is the probability to have 2 odd numbers in two spins?
$0.6 \times 0.6 = 0.36$

To verify if we did a good job, we add all the probabilities. We should get 1.
0.16+0.48+0.36 = 1

.

So to slide your bars, you slide them up to the number I gave you for each case.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

Answer from: Quest

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
