Question

The bar representing which of the following probabilities on a histogram would be the highest? A.1/30 B.1/15 C.1/10 D.2/15

help asap !! please

Answer 1

convert each fraction to a decimal number and that will allow you to compare the numbers easier

Answer 2

for example

1/30 = 0.0333333...

1/15 = 0.0666667

So we can see that 1/15 is larger than 1/30 since 0.0666667 is larger than 0.033333

Answer 3

so it would be b?

Answer 4

if you just had those two fractions, yes

but you need to compare the rest of the fractions

Answer 5

c is 0.1 and d is 0.13 so than it would be d than?

Answer 6

correct

Answer 7

oh okay thank you,

Answer 8

you're welcome

Answer 9

Do you know anything about this?

Answer 10

that's the combination of choosing 7 things out of 9

basically it's asking "how many ways are there to choose 7 items out of 9 where order does not matter"

Answer 11

I don't understand, cause the choices are A.66 B.55 C.36 D.45

Answer 12

have you learned about permutations?

Answer 13

no , this is online math,

Answer 14

I figured that, but I would have also figured that you have learned about permutations or combinations by now

Answer 15

seems odd how they skipped over that

Answer 16

No, it was never on any of the information given to me for each section,

Answer 17

well luckily we can take advantage of the fact that 9 C 7 = 9 C 2

9 C 2 = (9*8)/2 = ???

Answer 18

36

Answer 19

so 9 C 7 = 36 as well

Answer 20

you can also use Pascals triangle to get the same thing

Answer 21

what about this? If a probability distribution is 5/12,1/6 ,1/4 , x, what is the value of x? A.1/3 B.1/6 C.1/12 D.1/4

Answer 22

add up all the fractions including x and set it equal to 1

then solve for x

Answer 23

5/12 + 1/6 + 1/4 + x = 1

solve this for x

Answer 24

i don't know, 7/22?

Answer 25

no

Answer 26

oh wait, one sec

Answer 27

i don't undersad

Answer 28

understand*

Answer 29

what do you get when you combine these fractions

5/12 + 1/6 + 1/4

Answer 30

i don't know , cause they have different numbers do i need them both to get 12?

Answer 31

yes you need all the denominators to be equal to 12

Answer 32

12/12?

Answer 33

you multiply 6 with 2 and 4 with 3 ,

Answer 34

5/12 = 5/12

1/6 = 2/12

1/4 = 3/12

-----------------

5/12 + 1/6 + 1/4

is the same as

5/12 + 2/12 + 3/12

Answer 35

10/12 reduced to 5/6?

Answer 36

good

Answer 37

thaat not right

Answer 38

we're not done yet

Answer 39

oh

Answer 40

but we're on the right path to getting there

Answer 41

okay whats next?

Answer 42

5/12 + 1/6 + 1/4 + x = 1

is the same as

5/6 + x = 1


Now subtract 5/6 from both sides to isolate x


5/6 + x - 5/6 = 1 - 5/6

x = 1 - 5/6

x = ???

Answer 43

4/6 reduced to 2/3? but that not on there either?

Answer 44

nevermind 0.16666666666

Answer 45

no not this



but this
