It will take an additional 8 weeks to reach a height of 48 centimeters.
y = 4.5x
Since, the maximum height is 48 cm and the plant has already grown 12 cm, we deduct the 12 from 48 to get the additional weeks it needs to grow.
48 - 12 = 4.5x
36 = 4.5x
36/4.5 = 4.5x / 4.5
x = 8 weeks.

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.
Hey there! I'm happy to help!
Quotient means we are dividing. We are dividing A by the difference of 3 and B. Difference means subtract, so our algebraic expression is A/(3-B).
Have a wonderful day! :D
