Answer:
The mid-point is (9,-9/2)
Step-by-step explanation:
You would use the mid-point formula for this

if you plug that in it is (
)
resulting in (11/2,-2/2) = (11/2,-1)
Answer:
126250
Step-by-step explanation:
5.5% of 250000 is 13750 so you multiply 13750 by 9 which = 123750 then you subtract 123750 from 250000 so you get your answer
Answer:
the probability that at least one envelope is a yellow envelope is 16/21
Step-by-step explanation:
The probability that at least one envelope is a yellow envelope is P(Y);
P(Y) = 1 - P(Y)'
P(Y)' is the probability that no envelope is a yellow envelope.
Given;
red envelope = 1
blue envelopes = 3
green envelopes = 2
yellow envelopes = 3
Total = 9
Number of non-yellow envelope = 9 -3 = 6
(6 envelope are not yellow)
P(Y)' = P1 × P2 × P3
Since there is no replacement;
P(Y)' = 6/9 × 5/8 × 4/7
P(Y)' = 5/21
From equation 1;
P(Y) = 1 - 5/21
P(Y) = 16/21
the probability that at least one envelope is a yellow envelope is 16/21.
