Answer:
The Height is 15in
Step-by-step explanation:
V=L.W.H
300=10x2xH
300=20xH
300/20=H
H=15in
Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.
To answer the question, we need to know what probability is
<h3>What is probability?</h3>
This is the likelihood for an event to occur. It is given by
P(event) = number of required outcomes/total number of outcomes
Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.
<h3>Probability that all of Erica's flights will be on time</h3>
So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)
= [P(flight)]⁴
= (90%)⁴
= (0.9)⁴
= 0.656
≅ 0.66
= 66%
So, the probability that all of Erica's flights will be on time is B 66%.

Answer: The sunflower be 50 inches tall after 6 weeks.
Total height of sunflower in w weeks = 20+1.5 w,
Step-by-step explanation:
Given: In the beginning, the sunflower was 20 inches tall.
The sunflower then began to grow at a rate of 1.5 inches per week.
Then, total height of sunflower in 6 weeks = 20+1.5 ×20, where 1.5 ×20= growth in 6 weeks
= 20+30
= 50 inches
So, the sunflower be 50 inches tall after 6 weeks.
Let w = number of weeks, then
Total height of sunflower in w weeks = 20+1.5 w, where 1.5 w= growth in w weeks.
