a plant grows at a rate of 4.5 centimeters per week. it is now 12 centimeters tall. suppose that the plant continues to grow at
vredina [299]
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.

Consider a collection of envelopes consisting of 1 red envelope, 3 blue envelopes, 2 green envelopes, and 3 yellow envelopes if
nasty-shy [4]

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.

Translate the English phrase into an algebraic expression: the quotient of A and the difference of 3 and B.
xxMikexx [17]

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
