6 bicycles can be parked in a row in 6 which mean there is 720 ways to park the 6 bicycles
Answer:
a) 0.46; b) 0.41; c) 0.19; d) 0.59
Step-by-step explanation:
For part a,
There were 121 people that walked by; out of these 56 entered the store. This is an empirical probability of
56/121 ≈ 0.46
For part b,
There were 56 people that entered the store. Of those, 23 bought something. This is an empirical probability of
23/56 ≈ 0.41.
For part c,
We multiply the probability that someone walking by enters the store and the probability that someone entering the store buys something:
0.46(0.41) = 0.1886 ≈ 0.19
For part d,
Since the probability of someone entering the store buying something is 0.41, this means the probability that this person does not buy something is
1-0.41 = 0.59.
Answer:
Step-by-step explanation:
7/10 are black therefore 14/20 are black
Step-by-step explanation:
part A:
she can buy 8 of $1 items and and 5 $2 since
<em>$18 < $20</em>
she can buy 5 $1 items and and 7 $2 since
<em>$19 < $20</em>
she can buy 5 $3 items and and 8 $2 since
<em>$19 < $20</em>
<em></em>
part B:
let x represent $2 and y represent $1 , since she wants to spend below $20 this would be
part C:
refer to the attached graph for part c
the difference between the ordered pairs that falls on the line and the shaded area is 0
