Question

Essay; show all work. Last fall, a gardener planted 64 iris bulbs. She found that only 56 of the bulbs bloomed in the spring.



Find the empirical probability that an iris bulb of this type will bloom. Give answer as a fraction in lowest terms.
How many of the bulbs should she plant next fall if she would like at least 59 to bloom?

Answer 1

\[\frac{56}{64}=\frac{7}{8}\]

Answer 2

second question is ambiguous but your teacher probably wants you to solve
\[\frac{59}{x}=\frac{7}{8}\] for x

Answer 3

answer would be
\[x=\frac{59\times 8}{7}=67.42\] so i would say 68

Answer 4

how did u get 59/x=7/8?

Answer 5

oh you want 59 to bloom yes? 64 gives you 56 blooms so the ratio of "blooms" to "planted" is 7 to 8

Answer 6

you want 59 to something = 7 to 8, so you solve this via
\[\frac{59}{something} = \frac{7}{8}\]

Answer 7

oh ok...

Answer 8

if not clear we can think of it this way:
\[\frac{7}{8}=.875\] so 87.5% of the plants bloom. then it is like solving a percent problem "59 is 87.5% of what number?" the solution is the same

Answer 9

put in lots of words so teacher is impressed with your essay!

Answer 10

oh ok.. that makes sense

Answer 11

heres another one...

Answer 12

Essay; show all work. A community 5K run will award $50 to the winner. 65 people enter the race, and they each pay an entry fee of $20. Assuming they are all equally likely to win, what is a fair price for the competition? Round to the nearest cent.

Answer 13

wouldnt you take 50-20

Answer 14

i am a bit confused. it says the entry fee is $20. is that what you are supposed to adjust?

Answer 15

or are you supposed to adjust the winning amount?

Answer 16

i have no clue this is the question they asked.. and thats it.

Answer 17

well if they are only awarding $50 to the winner then each entrant should only pay
\[\frac{50}{65}\] dollars and that would break even

Answer 18

if they each payed 77 cents (rounded) then that would be $50 total. since each is equally likely to win they should each pay the same amount.

Answer 19

it asked for fair price for the competition round to nearest cent

Answer 20

so it would be 80 cents?

Answer 21

no to the nearest cent is 77

Answer 22

oh ok...

Answer 23

50/65=.7692... rounded give .77 or 77 cents

Answer 24

one last problem... lol
ty for helping me with this...
